-
-Use page_pool_alloc_pages instead of page_pool_dev_alloc_pages, which
-can give the gfp parameter, in the case of not supporting 64-bit width,
-using 32-bit address memory can reduce a copy from swiotlb.

-Subject: [PATCH] arm64: dts: rockchip: adjust rk3568 pll clocks
-
-The rk3568 gpll should run at 1200mhz and the ppll should run at 200mhz.
-These are set incorrectly by the bootloader, so fix them here.
-
-gpll boots at 1188mhz, but to get most accurate dividers for all
-gpll_dividers it needs to run at 1200mhz, otherwise everyone downstream
-isn't quite right.
-
-ppll feeds the combophys, which has a divide by 2 clock, so 200mhz is
-required to reach a 100mhz clock input for them.
-
-The vendor-kernel also makes this fix.

-I2S0 has not been added, as it is connected to HDMI and there is

-
-In the rockchip_thermal.c driver we now get the resets with
-a devm_reset_control_array_get() function, so remove
-the reset-names property as it is no longer needed.
-Although no longer required in rockchip-thermal.yaml
-sort tsadc-apb as first item.

-Subject: [PATCH] arm64: dts: rockchip: Add spi nodes on rk356x
-
-This adds the four spi nodes (spi0, spi1, spi2, spi3) to the
-rk356x dtsi. These are from the downstream device tree, though
-I have double-checked that their interrupts and DMA numbers are
-correct. I have also tested spi1 with an SPI device.

-Subject: [PATCH] arm64: dts: rockchip: drop pclk_xpcs from gmac0 on rk3568
-
-pclk_xpcs is not supported by mainline driver and breaks dtbs_check
-
-following warnings occour, and many more
-
-rk3568-evb1-v10.dt.yaml: ethernet@fe2a0000: clocks:
-    [[15, 386], [15, 389], [15, 389], [15, 184], [15, 180], [15, 181],
-    [15, 389], [15, 185], [15, 172]] is too long
-	From schema: Documentation/devicetree/bindings/net/snps,dwmac.yaml
-rk3568-evb1-v10.dt.yaml: ethernet@fe2a0000: clock-names:
-    ['stmmaceth', 'mac_clk_rx', 'mac_clk_tx', 'clk_mac_refout', 'aclk_mac',
-    'pclk_mac', 'clk_mac_speed', 'ptp_ref', 'pclk_xpcs'] is too long
-	From schema: Documentation/devicetree/bindings/net/snps,dwmac.yaml
-
-after removing it, the clock and other warnings are gone.
-
-pclk_xpcs on gmac is used to support QSGMII, but this requires a driver
-supporting it.
-Once xpcs support is introduced, the clock can be added to the
-documentation and both controllers.

- handles
-
-All nodes and handles related to USB have the prefix usb or usb2,
-whereas the phy handles are prefixed with u2phy. Rename for
-consistency reasons and to facilitate sorting.
-
-This patch also updates the handles in the only board file that
-uses them (rk3566-quartz64-a.dts).

- mode
-
-In the 3.0 device core, if the core is programmed to operate in
-2.0 only, then setting the GUCTL1.DEV_FORCE_20_CLK_FOR_30_CLK makes
-the internal 2.0(utmi/ulpi) clock to be routed as the 3.0 (pipe)
-clock. Enabling this feature allows the pipe3 clock to be not-running
-when forcibly operating in 2.0 device mode.

-Subject: [PATCH] mmc: dw-mmc-rockchip: Fix handling invalid clock rates
-
-The Rockchip rk356x ciu clock cannot be set as low as the dw-mmc
-hardware supports. This leads to a situation during card initialization
-where the clock is set lower than the clock driver can support. The
-dw-mmc-rockchip driver spews errors when this happens.
-For normal operation this only happens a few times during boot, but when
-cd-broken is enabled (in cases such as the SoQuartz module) this fires
-multiple times each poll cycle.
-
-Fix this by testing the lowest possible frequency that the clock driver
-can support which is within the mmc specification. Divide that rate by
-the internal divider and set f_min to this.

-Subject: [PATCH] PCI: rockchip-dwc: Reset core at driver probe
-
-The PCIe controller is in an unknown state at driver probe. This can
-lead to undesireable effects when the driver attempts to configure the
-controller.
-
-Prevent issues in the future by resetting the core during probe.

-
-clk_rtc_32k and its child clock clk_hdmi_cec detauls to a rate of 24 MHz
-and not to 32 kHz on RK356x.
-
-Fix this by assigning clk_rtc_32k a rate of 32768, also assign the parent
-to clk_rtc32k_frac.

-Subject: [PATCH] drm/rockchip: Add VOP2 driver
-
-The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
-It replaces the VOP unit found in the older Rockchip SoCs.
-
-This driver has been derived from the downstream Rockchip Kernel and
-heavily modified:
-
-- All nonstandard DRM properties have been removed
-- dropped struct vop2_plane_state and pass around less data between
-  functions
-- Dropped all DRM_FORMAT_* not known on upstream
-- rework register access to get rid of excessively used macros
-- Drop all waiting for framesyncs
-
-The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
-board. Overlay support is tested with the modetest utility. AFBC support
-on the cluster windows is tested with weston-simple-dmabuf-egl on
-weston using the (yet to be upstreamed) panfrost driver support.

-Subject: [PATCH] phy: rockchip: Support PCIe v3
-
-RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
-It use a dedicated PCIe-phy. Add support for this.
-
-Initial support by Shawn Lin, modifications by Peter Geis and Frank
-Wunderlich.
-
-Add data-lanes property for splitting pcie-lanes across controllers.
-
-The data-lanes is an array where x=0 means lane is disabled and  x > 0
-means controller x is assigned to phy lane.

-Subject: [PATCH] net: phy: add Motorcomm YT8531S phy id.
-
-We added patch for motorcomm.c to support YT8531S. This patch has
-been tested on AM335x platform which has one YT8531S interface
-card and passed all test cases.
-The tested cases indluding: YT8531S UTP function with support of
-10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
-and YT8531S Combo function that supports auto detection of media type.
-
-Since most functions of YT8531S are similar to YT8521 and we reuse some
-codes for YT8521 in the patch file.

-Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8521 gigabit
- ethernet phy
-
-Add dts support for Motorcomm yt8521 gigabit ethernet phy.
- Add ytphy_rgmii_clk_delay_config function to support dst config for
- the delay of rgmii clk. This funciont is common for yt8521, yt8531s
- and yt8531.
- This patch has been verified on AM335x platform.

- ethernet phy
-
-Add dts support for Motorcomm yt8531s gigabit ethernet phy.
- Change yt8521_probe to support clk config of yt8531s. Becase
- yt8521_probe does the things which yt8531s is needed, so
- removed yt8531s function.
- This patch has been verified on AM335x platform with yt8531s board.

-Subject: [PATCH] mmc: core: Improve fallback to speed modes if eMMC HS200
- fails
-
-In the error path of mmc_select_hs200() we are trying our best to restore
-the card/host into a valid state. This makes sense, especially if we
-encounter a simple switch error (-EBADMSG). However, rather than then
-continue with using the legacy speed mode, let's try the other better speed
-modes first. Additionally, let's update the card->mmc_avail_type to avoid
-us from trying a broken HS200 mode again.
-
-In an Amlogic S905W based TV box where the switch to HS200 mode fails for
-the eMMC, this allows us to use the eMMC in DDR mode in favor of the legacy
-mode, which greatly improves the performance.

-Subject: [PATCH] mmc: core: set initial signal voltage on power off
-
-Some boards have SD card connectors where the power rail cannot be switched
-off by the driver. If the card has not been power cycled, it may still be
-using 1.8V signaling after a warm re-boot. Bootroms expecting 3.3V signaling
-will fail to boot from a UHS card that continue to use 1.8V signaling.
-
-Set initial signal voltage in mmc_power_off() to allow re-boot to function.
-
-This fixes re-boot with UHS cards on Asus Tinker Board (Rockchip RK3288),
-same issue have been seen on some Rockchip RK3399 boards.
-
-I am sending this as a RFC because I have no insights into SD/MMC subsystem,
-this change fix a re-boot issue on my boards and does not break emmc/sdio.
-Is this an acceptable workaround? Any advice is appreciated.

-This is another shot at previous work submitted by Marty Jones
-<mj8263788@gmail.com> (https://lore.kernel.org/linux-arm-kernel/20201228152836.02795e09.mj8263788@gmail.com/),
-which is now a year old.
-
-v2: Following up on Robin Murphy's comments, the NEO3 DTS is now
-standalone and no longer includes the nanopi R2S one. The lan_led and
-wan_len nodes have been removed, and the sys_led node has been renamed
-to status_led in accordance with the board schematics.

-Subject: [PATCH] wifi: mac80211: fix receiving A-MSDU frames on mesh
- interfaces
-
-The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets
-on mesh interfaces, because it assumes that the Mesh Control field is always
-directly after the 802.11 header.
-802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is
-actually part of the A-MSDU subframe header.
-This makes more sense, since it allows packets for multiple different
-destinations to be included in the same A-MSDU, as long as RA and TID are
-still the same.
-Another issue is the fact that the A-MSDU subframe length field was apparently
-accidentally defined as little-endian in the standard.
-
-In order to fix this, the mesh forwarding path needs happen at a different
-point in the receive path.
-
-ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field
-and leave it in after the ethernet header. This also affects the source/dest
-MAC address fields, which now in the case of mesh point to the mesh SA/DA.
-
-ieee80211_amsdu_to_8023s is changed to deal with the endian difference and
-to add the Mesh Control length to the subframe length, since it's not covered
-by the MSDU length field.
-
-With these changes, the mac80211 will get the same packet structure for
-converted regular data packets and unpacked A-MSDU subframes.
-
-The mesh forwarding checks are now only performed after the A-MSDU decap.
-For locally received packets, the Mesh Control header is stripped away.
-For forwarded packets, a new 802.11 header gets added.

+ 24.
+
+DPI hasn't really been used up until now, so the default has
+been meaningless.
+In theory we should be able to pass the desired format for the
+adjacent bridge chip through, but framework seems to be missing
+for that.
+
+As the main device to use DPI is the VGA666 or Adafruit Kippah,
+both of which use RGB666, change the default to being RGB666 instead
+of RGB888.

+Subject: [PATCH] drm/vc4: Fix timings for VEC modes
+
+This commit fixes vertical timings of the VEC (composite output) modes
+to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R
+standards.
+
+Previous timings were actually defined as 502 and 601 lines, resulting
+in non-standard 62.69 Hz and 52 Hz signals being generated,
+respectively.
+
+Changes to vc4_crtc.c have also been made, to make the PixelValve
+vertical timings accurately correspond to the DRM modeline in interlaced
+modes. The resulting VERTA/VERTB register values have been verified
+against the reference values set by the Raspberry Pi firmware.

+Subject: [PATCH] drm/vc4: Fix definition of PAL-M mode
+
+PAL-M is a Brazilian analog TV standard that uses a PAL-style chroma
+subcarrier at 3.575611[888111] MHz on top of 525-line (480i60) timings.
+This commit makes the driver actually use the proper VEC preset for this
+mode instead of just changing PAL subcarrier frequency.
+
+DRM mode constant names have also been changed, as they no longer
+correspond to the "NTSC" or "PAL" terms.

+Subject: [PATCH] drm/vc4: Add support for more analog TV standards
+
+Add support for the following composite output modes (all of them are
+somewhat more obscure than the previously defined ones):
+
+- NTSC_443 - NTSC-style signal with the chroma subcarrier shifted to
+  4.43361875 MHz (the PAL subcarrier frequency). Never used for
+  broadcasting, but sometimes used as a hack to play NTSC content in PAL
+  regions (e.g. on VCRs).
+- PAL_N - PAL with alternative chroma subcarrier frequency,
+  3.58205625 MHz. Used as a broadcast standard in Argentina, Paraguay
+  and Uruguay to fit 576i50 with colour in 6 MHz channel raster.
+- PAL60 - 480i60 signal with PAL-style color at normal European PAL
+  frequency. Another non-standard, non-broadcast mode, used in similar
+  contexts as NTSC_443. Some displays support one but not the other.
+- SECAM - French frequency-modulated analog color standard; also have
+  been broadcast in Eastern Europe and various parts of Africa and Asia.
+  Uses the same 576i50 timings as PAL.
+
+Also added some comments explaining color subcarrier frequency
+registers.

+Subject: [PATCH] drm/vc4: Allow setting the TV norm via module parameter
+
+Similar to the ch7006 and nouveau drivers, introduce a "tv_mode" module
+parameter that allow setting the TV norm by specifying vc4.tv_norm= on
+the kernel command line.
+
+If that is not specified, try inferring one of the most popular norms
+(PAL or NTSC) from the video mode specified on the command line. On
+Raspberry Pis, this causes the most common cases of the sdtv_mode
+setting in config.txt to be respected.

+during drm_mode_obj_set_property_ioctl(). Set crtc_state->mode_changed
+if TV norm changes even without explicit mode change. This makes things

+"drm/vc4: Set the possible crtcs mask correctly for planes with FKMS"
+plus a couple of minor fixups for the 5.9 branch.

+
+drm/vc4: Make normalize_zpos conditional on using fkms
+
+Eric's view was that there was no point in having zpos
+support on vc4 as all the planes had the same functionality.
+
+Can be later squashed into (and fixes):

+From: Dave Stevenson <dave.stevenson@raspberrypi.com>
+Date: Tue, 27 Apr 2021 14:24:21 +0200
+Subject: [PATCH] drm/vc4: Add support for gamma on BCM2711
+
+BCM2711 changes from a 256 entry lookup table to a 16 point
+piecewise linear function as the pipeline bitdepth has increased
+to make a LUT unwieldy.
+
+Implement a simple conversion from a 256 entry LUT that userspace
+is likely to expect to 16 evenly spread points in the PWL. This
+could be improved with curve fitting at a later date.

+Subject: [PATCH] drm/vc4: hvs: Force modeset on gamma lut change
+
+The HVS Gamma block can only be updated when idle, so we need to disable
+the HVS channel when the gamma property is set in an atomic commit.
+
+Since the pixelvalve cannot have its assigned channel halted without
+stalling unless it's disabled as well, in our case that means forcing a
+full disable / enable cycle on the pipeline.

+Subject: [PATCH] drm/vc4: Enable gamma block only when required.
+
+With HVS5 the gamma block is now only reprogrammed with
+a disable/enable. Loading the table from vc4_hvs_init_channel
+(called from vc4_hvs_atomic_enable) appears to be at an
+invalid point in time and so isn't applied.
+
+Switch to enabling and disabling the gamma table instead. This
+isn't safe if the pipeline is running, but it isn't now.
+For HVS4 it is safe to enable and disable dynamically, so
+adopt that approach there too.

+Subject: [PATCH] drm/vc4: Disable Gamma control on HVS5 due to issues writing
+ the table
+
+Still under investigation, but the conditions under which the HVS
+will accept values written to the gamma PWL are not straightforward.
+
+Disable gamma on HVS5 again until it can be resolved to avoid
+gamma being enabled with an incorrect table.

+ drm_panel
+
+Current usage of drm_connector_set_panel_orientation is from a panel's
+get_modes call. However if the panel orientation property doesn't
+exist on the connector at this point, then drm_mode_object triggers
+WARNs as the connector is already registered.
+
+Add an orientation variable to struct drm_panel and initialise it from
+drm_panel_init.
+panel_bridge_attach can then create the property before the connector
+is registered.

+
+Breaking the bridge chain does not work for atomic bridges/panels
+and generally causes issues.

+are called, so move that to encoder_mode_set in the same way that

+Subject: [PATCH] drm/vc4: Remove splitting the bridge chain from the driver.
+
+Splitting the bridge chain fails for atomic bridges as the
+framework can't add the relevant state in
+drm_atomic_add_encoder_bridges.
+The chain was split because we needed to power up before
+calling pre_enable, but that is now done in mode_set, and will
+move into the framework.

+
+Remove the encoder functions, and create a bridge attached to

+
+As a bridge has state which an encoder doesn't, we need to
+add the state management functions as well.
+
+As there is no bridge atomic_mode_set, move the initialisation
+code that was in mode_set into _pre_enable.
+The code to actually enable and disable sending video are split
+from the general control into _enable and _disable.

+Subject: [PATCH] drm/vc4: Remove entry to ULPS from vc4_dsi post_disable
+
+Post_disable was sending the D-PHY sequence to put any device
+into ULPS suspend mode, and then cutting power to the DSI block.
+The power-on reset state of the DSI block is for DSI to be in
+an operational state, not ULPS, so it then never sent the sequence
+for exiting ULPS. Any attached device that didn't have an external
+reset therefore remained in ULPS / standby, and didn't function.
+
+Use of ULPS isn't well specified in DRM, therefore remove entering
+it to avoid the above situation.

+Subject: [PATCH] drm/vc4: hdmi: Add CSC for BT601/709/2020 limited and full
+ range output
+
+The HVS always composes in the RGB domain, but there is a colourspace
+conversion block on the output to allow for sending YCbCr over the
+HDMI interface.
+The colourspace on that link is configurable via the "Colorspace"
+property on the connector, and that updates the infoframes. There
+is also selection of limited or full range based on the mode selected
+or an override.
+
+Add code to update the CSC as well so that the metadata matches the
+image data.
+

+
+When the margins are changed, the dlist needs to be regenerated
+with the changed updated dest regions for each of the planes.
+
+Setting the zpos_changed flag is sufficient to trigger that

+Subject: [PATCH] drm/atomic-helpers: remove legacy_cursor_update hacks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The stuff never really worked, and leads to lots of fun because it
+out-of-order frees atomic states. Which upsets KASAN, among other
+things.
+
+For async updates we now have a more solid solution with the
+->atomic_async_check and ->atomic_async_commit hooks. Support for that
+for msm and vc4 landed. nouveau and i915 have their own commit
+routines, doing something similar.
+
+For everyone else it's probably better to remove the use-after-free
+bug, and encourage folks to use the async support instead. The
+affected drivers which register a legacy cursor plane and don't either
+use the new async stuff or their own commit routine are: amdgpu,
+atmel, mediatek, qxl, rockchip, sti, sun4i, tegra, virtio, and vmwgfx.
+
+Inspired by an amdgpu bug report.
+
+v2: Drop RFC, I think with amdgpu converted over to use
+atomic_async_check/commit done in
+

+
+    drm/amd/display: Add fast path for cursor plane updates
+
+we don't have any driver anymore where we have userspace expecting
+solid legacy cursor support _and_ they are using the atomic helpers in
+their fully glory. So we can retire this.
+
+v3: Paper over msm and i915 regression. The complete_all is the only
+thing missing afaict.
+
+v4: Rebased on recent kernel, added extra link for vc4 bug.

+Subject: [PATCH] drm/vc4: Add async update support for cursor planes
+
+Now that cursors are implemented as regular planes, all cursor
+movements result in atomic updates. As the firmware-kms driver
+doesn't support asynchronous updates, these are synchronous, which
+limits the update rate to the screen refresh rate. Xorg seems unaware
+of this (or at least of the effect of this), because if the mouse is
+configured with a higher update rate than the screen then continuous
+mouse movement results in an increasing backlog of mouse events -
+cue extreme lag.
+
+Add minimal support for asynchronous updates - limited to cursor
+planes - to eliminate the lag.
+
+See: https://github.com/raspberrypi/linux/pull/4971

+Subject: [PATCH] drm/vc4: Configure the HVS COB allocations
+
+The HVS Composite Output Buffer (COB) is the memory used to
+generate the output pixel data.
+Until now the vc4 driver has been relying on the firmware to
+have set these to sensible values.
+
+In testing triple screen support it has been noted that only
+1 line was being assigned to HVS channel 2. Whilst that is fine
+for the transposer (TXP), and indeed needed as only some pixels
+have an alpha channel, it is insufficient to run a live display.
+
+Split the COB more evenly between the 3 HVS channels.

+Subject: [PATCH] drm/vc4: Set AXI panic modes for the HVS
+
+The HVS can change AXI request mode based on how full the COB
+FIFOs are.
+Until now the vc4 driver has been relying on the firmware to
+have set these to sensible values.
+
+With HVS channel 2 now being used for live video, change the
+panic mode for all channels to be explicitly set by the driver,
+and the same for all channels.

+Subject: [PATCH] clk: bcm: rpi: Create helper to retrieve private data
+
+The RaspberryPi firmware clocks driver uses in several instances a
+container_of to retrieve the struct raspberrypi_clk_data from a pointer
+to struct clk_hw. Let's create a small function to avoid duplicating it
+all over the place.

+Subject: [PATCH] BCM2708: Add core Device Tree support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add the bare minimum needed to boot BCM2708 from a Device Tree.

+
+BCM2708: DT: change 'axi' nodename to 'soc'
+
+Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
+The VC4 bootloader fills in certain properties in the 'axi' subtree,
+but since this is part of an upstreaming effort, the name is changed.

+
+BCM2708_DT: Correct length of the peripheral space
+
+Use dts-dirs feature for overlays.
+
+The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
+
+Using this fixes the install_dtbs target, which previously did not install the overlays.

+
+BCM270X_DT: switch to bcm2835-i2s
+
+I2S soundcard drivers with proper devicetree support (i.e. not linking
+to the cpu_dai/platform via name but to cpu/platform via of_node)
+will work out of the box without any modifications.
+
+When the kernel is compiled without devicetree support the platform
+code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
+will link to it via name, as before.

+SDIO-overlay: add poll_once-boolean parameter
+

+
+BCM270X_DT: Make mmc overlay compatible with current firmware
+
+The original DT overlay logic followed a merge-then-patch procedure,
+i.e. parameters are applied to the loaded overlay before the overlay
+is merged into the base DTB. This sequence has been changed to
+patch-then-merge, in order to support parameterised node names, and
+to protect against bad overlays. As a result, overrides (parameters)
+must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
+
+mmc-overlay.dts (that switches back to the original mmc sdcard
+driver) is the only overlay violating that rule, and this patch
+fixes it.
+
+bcm270x_dt: Use the sdhost MMC controller by default
+
+The "mmc" overlay reverts to using the other controller.
+
+squash: Add cprman to dt
+
+BCM270X_DT: Use clk_core for I2C interfaces
+
+BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
+
+The mainline Device Tree files are quite close to downstream now.
+Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
+for our dts files.
+
+Mainline dts files are based on these files:
+
+          bcm2835-rpi.dtsi
+  bcm2835.dtsi    bcm2836.dtsi
+          bcm283x.dtsi
+
+Current downstream are based on these:
+
+  bcm2708.dtsi    bcm2709.dtsi    bcm2710.dtsi
+             bcm2708_common.dtsi
+
+This patch introduces this dependency:
+
+  bcm2708.dtsi    bcm2709.dtsi
+          bcm2708-rpi.dtsi
+          bcm270x.dtsi
+  bcm2835.dtsi    bcm2836.dtsi
+          bcm283x.dtsi
+
+And:
+          bcm2710.dtsi
+          bcm2708-rpi.dtsi
+          bcm270x.dtsi
+          bcm283x.dtsi
+
+bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
+bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
+
+Other changes:
+- The led node has moved from /soc/leds to /leds. This is not a problem
+  since the label is used to reference it.
+- The clk_osc reg property changes from 6 to 3.
+- The gpu nodes has their interrupt property set in the base file.
+- the clocks label does not point to the /clocks node anymore, but
+  points to the cprman node. This is not a problem since the overlays
+  that use the clock node refer to it directly: target-path = "/clocks";
+- some nodes now have 2 labels since mainline and downstream differs in
+  this respect: cprman/clocks, spi0/spi, gpu/vc4.
+- some nodes doesn't have an explicit status = "okay" since they're not
+  disabled in the base file: watchdog and random.
+- gpiomem doesn't need an explicit status = "okay".
+- bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
+  it's now set directly in that file.
+- bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
+- Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

+BCM270X_DT: Don't generate "linux,phandle" props
+
+The EPAPR standard says to use "phandle" properties to store phandles,
+rather than the deprecated "linux,phandle" version. By default, dtc
+generates both, but adding "-H epapr" causes it to only generate
+"phandle"s, saving some space and clutter.

+MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The

+so that requesting 38.4kbaud actually gets 31.25kbaud.

++Introduction
++============
++
++This directory contains Device Tree overlays. Device Tree makes it possible
++to support many hardware configurations with a single kernel and without the
++need to explicitly load or blacklist kernel modules. Note that this isn't a
++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
++are still configured by the board support code, but the intention is to
++eventually reach that goal.
++
++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
++default, the Raspberry Pi kernel boots with device tree enabled. You can
++completely disable DT usage (for now) by adding:
++
++    device_tree=
++
++to your config.txt, which should cause your Pi to revert to the old way of
++doing things after a reboot.
++
++In /boot you will find a .dtb for each base platform. This describes the
++hardware that is part of the Raspberry Pi board. The loader (start.elf and its
++siblings) selects the .dtb file appropriate for the platform by name, and reads
++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
++are disabled, but they can be enabled using Device Tree parameters:
++
++    dtparam=i2c=on,i2s=on,spi=on
++
++However, this shouldn't be necessary in many use cases because loading an
++overlay that requires one of those interfaces will cause it to be enabled
++automatically, and it is advisable to only enable interfaces if they are
++needed.
++
++Configuring additional, optional hardware is done using Device Tree overlays
++(see below).
++
++GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
++not the physical pin numbers.
++
++raspi-config
++============
++
++The Advanced Options section of the raspi-config utility can enable and disable
++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
++is possible to both enable an interface and blacklist the driver, if for some
++reason you should want to defer the loading.
++
++Modules
++=======
++
++As well as describing the hardware, Device Tree also gives enough information
++to allow suitable driver modules to be located and loaded, with the corollary
++that unneeded modules are not loaded. As a result it should be possible to
++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
++have its contents deleted (or commented out).
++
++Using Overlays
++==============
++
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++    modprobe i2c-bcm2835
++    modprobe rtc-ds1307
++    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
++
++With DT enabled, this becomes a line in config.txt:
++
++    dtoverlay=i2c-rtc,ds1307
++
++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++    dtoverlay=i2c-rtc,ds1307,addr=0x68
++
++Parameters usually have default values, although certain parameters are
++mandatory. See the list of overlays below for a description of the parameters
++and their defaults.
++
++Making new Overlays based on existing Overlays
++==============================================
++
++Recent overlays have been designed in a more general way, so that they can be
++adapted to hardware by changing their parameters. When you have additional
++hardware with more than one device of a kind, you end up using the same overlay
++multiple times with other parameters, e.g.
++
++    # 2 CAN FD interfaces on spi but with different pins
++    dtoverlay=mcp251xfd,spi0-0,interrupt=25
++    dtoverlay=mcp251xfd,spi0-1,interrupt=24
++
++    # a realtime clock on i2c
++    dtoverlay=i2c-rtc,pcf85063
++
++While this approach does work, it requires knowledge about the hardware design.
++It is more feasible to simplify things for the end user by providing a single
++overlay as it is done the traditional way.
++
++A new overlay can be generated by using ovmerge utility.
++https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge
++
++To generate an overlay for the above configuration we pass the configuration
++to ovmerge and add the -c flag.
++
++    ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \
++               mcp251xfd-overlay.dts,spi0-1,interrupt=24 \
++               i2c-rtc-overlay.dts,pcf85063 \
++    >> merged-overlay.dts
++
++The -c option writes the command above as a comment into the overlay as
++a marker that this overlay is generated and how it was generated.
++After compiling the overlay it can be loaded in a single line.
++
++    dtoverlay=merged
++
++It does the same as the original configuration but without parameters.

++Name:   fbtft
++Info:   Overlay for SPI-connected displays using the fbtft drivers.
++
++        This overlay seeks to replace the functionality provided by fbtft_device
++        which is now gone from the kernel.
++
++        Most displays from fbtft_device have been ported over.
++        Example:
++          dtoverlay=fbtft,spi0-0,rpi-display,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
++
++        It is also possible to specify the controller (this will use the default
++        init sequence in the driver).
++        Example:
++          dtoverlay=fbtft,spi0-0,ili9341,bgr,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
++
++        For devices on spi1 or spi2, the interfaces should be enabled
++        with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
++
++        The following features of fbtft_device have not been ported over:
++        - parallel bus is not supported
++        - the init property which overrides the controller initialization
++          sequence is not supported as a parameter due to memory limitations in
++          the bootloader responsible for applying the overlay.
++
++        See https://github.com/notro/fbtft/wiki/FBTFT-RPI-overlays for how to
++        create an overlay.

++Name:   gpio-led
++Info:   This is a generic overlay for activating LEDs (or any other component)
++        by a GPIO pin. Multiple LEDs can be set up using multiple calls to the
++        overlay. While there are many existing methods to activate LEDs on the
++        RPi, this method offers some advantages:
++        1) Does not require any userspace programs.
++        2) LEDs can be connected to the kernel's led-trigger framework,
++           and drive the LED based on triggers such as cpu load, heartbeat,
++           kernel panic, key input, timers and others.
++        3) LED can be tied to the input state of another GPIO pin.
++        4) The LED is setup early during the kernel boot process (useful
++           for cpu/heartbeat/panic triggers).
++
++        Typical electrical connection is:
++           RPI-GPIO.19  ->  LED  -> 300ohm resister  -> RPI-GND
++        The GPIO pin number can be changed with the 'gpio=' parameter.
++
++        To control an LED from userspace, write a 0 or 1 value:
++           echo 1 > /sys/class/leds/myled1/brightness
++        The 'myled1' name can be changed with the 'label=' parameter.
++
++        To connect the LED to a kernel trigger from userspace:
++           echo cpu > /sys/class/leds/myled1/trigger
++           echo heartbeat > /sys/class/leds/myled1/trigger
++           echo none > /sys/class/leds/myled1/trigger
++        To connect the LED to GPIO.26 pin (physical pin 37):
++           echo gpio > /sys/class/leds/myled1/trigger
++           echo 26 > /sys/class/leds/myled1/gpio
++        Available triggers:
++           cat /sys/class/leds/myled1/trigger

++                                /sys/class/leds/<label> . Default 'myled1'.
++        trigger                 Set the led-trigger to connect to this LED.
++                                default 'none' (LED is user-controlled).
++                                Some possible triggers:
++                                 cpu - CPU load (all CPUs)
++                                 cpu0 - CPU load of first CPU.
++                                 mmc - disk activity (all disks)
++                                 panic - turn on on kernel panic
++                                 heartbeat - indicate system health
++                                 gpio - connect to a GPIO input pin (note:
++                                        currently the GPIO PIN can not be set

++                                will turn on the GPIO/LED). Default '0'.

++Name:   gpio-no-bank0-irq
++Info:   Use this overlay to disable GPIO interrupts for GPIOs in bank 0 (0-27),
++        which can be useful for UIO drivers.
++        N.B. Using this overlay will trigger a kernel WARN during booting, but
++        this can safely be ignored - the system should work as expected.
++Load:   dtoverlay=gpio-no-bank0-irq

++Name:   gpio-no-irq

++Load:   dtoverlay=gpio-no-irq
++Params: <None>
++
++
++Name:   gpio-poweroff
++Info:   Drives a GPIO high or low on poweroff (including halt). Using this
++        overlay interferes with the normal power-down sequence, preventing the
++        kernel from resetting the SoC (a necessary step in a normal power-off
++        or reboot). This also disables the ability to trigger a boot by driving
++        GPIO3 low.
++
++        The GPIO starts in an inactive state. At poweroff time it is driven
++        active for 100ms, then inactive for 100ms, then active again. It is
++        safe to remove the power at any point after the initial activation of
++        the GPIO.
++
++        Users of this overlay are required to provide an external mechanism to
++        switch off the power supply when signalled - failure to do so results
++        in a kernel BUG, increased power consumption and undefined behaviour.
++Load:   dtoverlay=gpio-poweroff,<param>=<val>
++Params: gpiopin                 GPIO for signalling (default 26)
++
++        active_low              Set if the power control device requires a
++                                high->low transition to trigger a power-down.
++                                Note that this will require the support of a
++                                custom dt-blob.bin to prevent a power-down
++                                during the boot process, and that a reboot
++                                will also cause the pin to go low.
++        input                   Set if the gpio pin should be configured as
++                                an input.
++        export                  Set to export the configured pin to sysfs
++        active_delay_ms         Initial GPIO active period (default 100)
++        inactive_delay_ms       Subsequent GPIO inactive period (default 100)
++        timeout_ms              Specify (in ms) how long the kernel waits for
++                                power-down before issuing a WARN (default 3000).
++
++
++Name:   gpio-shutdown
++Info:   Initiates a shutdown when GPIO pin changes. The given GPIO pin
++        is configured as an input key that generates KEY_POWER events.
++
++        This event is handled by systemd-logind by initiating a
++        shutdown. Systemd versions older than 225 need an udev rule
++        enable listening to the input device:
++
++                ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
++                        SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
++                        ATTRS{keys}=="116", TAG+="power-switch"
++
++        Alternatively this event can be handled also on systems without
++        systemd, just by traditional SysV init daemon. KEY_POWER event
++        (keycode 116) needs to be mapped to KeyboardSignal on console
++        and then kb::kbrequest inittab action which is triggered by
++        KeyboardSignal from console can be configured to issue system
++        shutdown. Steps for this configuration are:
++
++            Add following lines to the /etc/console-setup/remap.inc file:
++
++                # Key Power as special keypress
++                keycode 116 = KeyboardSignal
++
++            Then add following lines to /etc/inittab file:
++
++                # Action on special keypress (Key Power)
++                kb::kbrequest:/sbin/shutdown -t1 -a -h -P now
++
++            And finally reload configuration by calling following commands:
++
++                # dpkg-reconfigure console-setup
++                # service console-setup reload
++                # init q
++
++        This overlay only handles shutdown. After shutdown, the system
++        can be powered up again by driving GPIO3 low. The default
++        configuration uses GPIO3 with a pullup, so if you connect a
++        button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
++        you get a shutdown and power-up button. Please note that
++        Raspberry Pi 1 Model B rev 1 uses GPIO1 instead of GPIO3.

++        Do NOT use in conjunction with dtparam=i2c_vc=on. From the 5.4 kernel

++        dtparam=i2c_vc=on will try and enable the mux, so combining the two

++Info:   Watterott RPi-Display - 2.8" Touch Display
++        Linux has 2 drivers that support this display and this overlay supports
++        both.
++
++        Examples:
++          fbtft/fb_ili9341: dtoverlay=watterott-display
++          drm/mi0283qt: dtoverlay=watterott-display,drm,backlight-pwm,rotate=180
++
++        Some notable differences with the DRM driver compared to fbtft:
++        - The display is turned on when it's first used and not on driver load
++          as with fbtft. So if nothing uses the display it stays off.
++        - Can run with a higher SPI clock increasing framerate. This is possible
++          since the driver avoids messing up the controller configuration due to
++          transmission errors by running config commands at 10MHz and only pixel
++          data at full speed (occasional pixel glitch might occur).
++        - PWM backlight is supported.

++Troubleshooting
++===============
++
++If you are experiencing problems that you think are DT-related, enable DT
++diagnostic output by adding this to /boot/config.txt:
++
++    dtdebug=on
++
++and rebooting. Then run:
++
++    sudo vcdbg log msg
++
++and look for relevant messages.
++
++Further reading
++===============
++
++This is only meant to be a quick introduction to the subject of Device Tree on
++Raspberry Pi. There is a more complete explanation here:

++ * PiFace Digital, Device Tree Overlay.
++ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
++ *
++ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
++ * SPI GPIO port expander.
++ *
++ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
++ * and LEDs, plus two relays on the first two outputs. These output loads are
++ * active-high.
++ *
++ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
++ * with four on-board switches connecting them to ground. Inputs devices are
++ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
++ * activated for GPIO bank B.
++ *
++ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
++ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
++ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
++ * and JP2.
++ *
++ * You can tell the driver about these jumper configurations with the
++ * spi-present-mask bitmask:
++ *
++ *     | JP1 | JP2 | dtoverlay line in /boot/config.txt         |
++ *     | --- | --- | ------------------------------------------ |
++ *     |  0  |  0  | dtoverlay=pifacedigital                    |
++ *     |  0  |  0  | dtoverlay=pifacedigital:spi-present-mask=1 |
++ *     |  0  |  1  | dtoverlay=pifacedigital:spi-present-mask=2 |
++ *     |  1  |  0  | dtoverlay=pifacedigital:spi-present-mask=4 |
++ *     |  1  |  1  | dtoverlay=pifacedigital:spi-present-mask=8 |
++ *
++ * # Example
++ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
++ *
++ *     $ grep pifacedigital /boot/config.txt
++ *     dtoverlay=pifacedigital
++ *     $ sudo systemctl poweroff
++ *
++ * Attach the PiFace Digital and power on the Raspberry Pi.
++ * Then use the libgpiod tools to query the device:
++ *
++ *     $ sudo apt install gpiod
++ *     $ gpiodetect | grep mcp23s17
++ *     gpiochip2 [mcp23s17.0] (16 lines)
++ *
++ * Set GPIO outputs 0, 2 and 5:
++ *
++ *     $ gpioset gpiochip2 0=1 2=1 5=1
++ *
++ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
++ *
++ *     $ gpioget gpiochip2 {8..15}
++ *     1 1 1 1 1 1 1 1
++ *
++ * And even monitor interrupts:
++ *
++ *     $ gpiomon gpiochip2 {8..15}
++ *     event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
++ *     event:  RISING EDGE offset: 11 timestamp: [1597361663.062555051]

+Subject: [PATCH] Register the clocks early during the boot process, so that
+ special/critical clocks can get enabled early on in the boot process avoiding
+ the risk of disabling a clock, pll_divider or pll when a claiming driver
+ fails to install propperly - maybe it needs to defer.

+Subject: [PATCH] clk-bcm2835: Read max core clock from firmware
+
+The VPU is responsible for managing the core clock, usually under
+direction from the bcm2835-cpufreq driver but not via the clk-bcm2835
+driver. Since the core frequency can change without warning, it is
+safer to report the maximum clock rate to users of the core clock -
+I2C, SPI and the mini UART - to err on the safe side when calculating
+clock divisors.
+
+If the DT node for the clock driver includes a reference to the
+firmware node, use the firmware API to query the maximum core clock
+instead of reading the divider registers.
+
+Prior to this patch, a "100KHz" I2C bus was sometimes clocked at about
+160KHz. In particular, switching to the 4.9 kernel was likely to break
+SenseHAT usage on a Pi3.

+Subject: [PATCH] Revert "Bluetooth: Always request for user confirmation for
+ Just Works (LE SC)"
+
+This reverts commit ffee202a78c2980688bc5d2f7d56480e69a5e0c9.
+
+The commit "Bluetooth: Always request for user confirmation for Just
+Works" prevents BLE devices pairing in (at least) the Raspberry Pi OS
+GUI. After reverting it, pairing works again. Although this companion
+commit ("... (LE SC)") has not been demonstrated to be problematic,
+it follows the same logic and therefore could affect some use cases.
+
+If another solution to the problem is found then this reversion will
+be removed.
+

+Subject: [PATCH] Revert "Bluetooth: Always request for user confirmation for
+ Just Works"
+
+This reverts commit 92516cd97fd4d8ad5b1421a0d51771044f453a5f.
+
+Thi commit "Bluetooth: Always request for user confirmation for Just
+Works" prevents BLE devices pairing in (at least) the Raspberry Pi OS
+GUI. After reverting it, pairing works again.
+
+If another solution to the problem is found then this reversion will
+be removed.

+
+SQUASH: smsc95xx: Use dev_mod_addr to set MAC addr
+
+Since adeef3e32146 ("net: constify netdev->dev_addr") it has been
+illegal to write to the dev_addr MAC address field. Later commits
+have added explicit checks that it hasn't been modified by nefarious
+means. The dev_addr_mod helper function is the accepted way to change
+the dev_addr field, so use it.
+
+Squash with 96c1def63ee1 ("Allow mac address to be set in smsc95xx").

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add a duplicate irq range with an offset on the hwirq's so the
+driver can detect that enable_fiq() is used.
+Tested with downstream dwc_otg USB controller driver.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Raspberry Pi firmware looks at the RSTS register to know which
+partition to boot from. The reboot syscall command
+LINUX_REBOOT_CMD_RESTART2 supports passing in a string argument.
+
+Add support for passing in a partition number 0..63 to boot from.
+Partition 63 is a special partiton indicating halt.
+If the partition doesn't exist, the firmware falls back to partition 0.

+Subject: [PATCH] Update vfpmodule.c
+
+Christopher Alexander Tobias Schulze - May 2, 2015, 11:57 a.m.
+This patch fixes a problem with VFP state save and restore related
+to exception handling (panic with message "BUG: unsupported FP
+instruction in kernel mode") present on VFP11 floating point units
+(as used with ARM1176JZF-S CPUs, e.g. on first generation Raspberry
+Pi boards). This patch was developed and discussed on
+
+   https://github.com/raspberrypi/linux/issues/859
+
+A precondition to see the crashes is that floating point exception
+traps are enabled. In this case, the VFP11 might determine that a FPU
+operation needs to trap at a point in time when it is not possible to
+signal this to the ARM11 core any more. The VFP11 will then set the
+FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases,
+a second opcode might have been accepted by the VFP11 before the
+exception was detected and could be reported to the ARM11 - in this
+case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in
+FPINST2.)
+
+If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued
+by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode
+trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits
+to decide what actions to take, i.e., whether to emulate the opcodes
+found in FPINST and FPINST2, and whether to retry the bounced instruction.
+
+If a user space application has left the VFP11 in this "pending trap"
+state, the next FPU opcode issued to the VFP11 might actually be the
+VSTMIA operation vfp_save_state() uses to store the FPU registers
+to memory (in our test cases, when building the signal stack frame).
+In this case, the kernel crashes as described above.
+
+This patch fixes the problem by making sure that vfp_save_state() is
+always entered with FPEXC.EX cleared. (The current value of FPEXC has
+already been saved, so this does not corrupt the context. Clearing
+FPEXC.EX has no effects on FPINST or FPINST2. Also note that many
+callers already modify FPEXC by setting FPEXC.EN before invoking
+vfp_save_state().)
+
+This patch also addresses a second problem related to FPEXC.EX: After
+returning from signal handling, the kernel reloads the VFP context
+from the user mode stack. However, the current code explicitly clears
+both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these
+bits to be preserved, this patch disables clearing them for VFP
+implementations belonging to architecture 1. There should be no
+negative side effects: the user can set both bits by executing FPU
+opcodes anyway, and while user code may now place arbitrary values
+into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support
+code knows which instructions can be emulated, and rejects other
+opcodes with "unhandled bounce" messages, so there should be no
+security impact from allowing reloading FPEXC.EX and FPEXC.FP2V.

+Subject: [PATCH] i2c: bcm2835: Add debug support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds a debug module parameter to aid in debugging transfer issues
+by printing info to the kernel log. When enabled, status values are
+collected in the interrupt routine and msg info in
+bcm2835_i2c_start_transfer(). This is done in a way that tries to avoid
+affecting timing. Having printk in the isr can mask issues.
+
+debug values (additive):
+1: Print info on error
+2: Print info on all transfers
+3: Print messages before transfer is started
+
+The value can be changed at runtime:
+/sys/module/i2c_bcm2835/parameters/debug
+
+Example output, debug=3:
+[  747.114448] bcm2835_i2c_xfer: msg(1/2) write addr=0x54, len=2 flags= [i2c1]

+Subject: [PATCH] irqchip: irq-bcm2836: Remove regmap and syscon use
+
+The syscon node defines a register range that duplicates that used by
+the local_intc node on bcm2836/7. Since irq-bcm2835 and irq-bcm2836 are
+built in and always present together (both drivers are enabled by
+CONFIG_ARCH_BCM2835), it is possible to replace the syscon usage with a
+global variable that simplifies the code. Doing so does lose the
+locking provided by regmap, but as only one side is using the regmap
+interface (irq-bcm2835 uses readl and write) there is no loss of
+atomicity.

+The pl011 register accessor functions use the _relaxed versions of the

+automatic memory barriers. When polling a FIFO status register to check
+for fullness, it is necessary to ensure that any outstanding writes have
+completed; otherwise the flags are effectively stale, making it possible
+that the next write is to a full FIFO.

+Subject: [PATCH] amba_pl011: Add cts-event-workaround DT property
+
+The BCM2835 PL011 implementation seems to have a bug that can lead to a
+transmission lockup if CTS changes frequently. A workaround was added to
+the driver with a vendor-specific flag to enable it, but this flag is
+currently not set for ARM implementations.
+
+Add a "cts-event-workaround" property to Pi DTBs and use the presence
+of that property to force the flag to be enabled in the driver.

+Subject: [PATCH] tty: amba-pl011: Avoid rare write-when-full error
+
+Under some circumstances on BCM283x processors data loss can be
+observed - a single byte missing from the TX output stream. These bytes
+are always the last byte of a batch of 8 written from pl011_tx_chars
+when from_irq is true, meaning that the FIFO full flag is not checked
+before writing.
+
+The transmit optimisation relies on the FIFO being half-empty when the
+TX interrupt is raised. Instrumenting the driver further showed that
+the failure case correlated with the TX FIFO full flag being set at the
+point where the last byte was written to the data register, which
+explains the data loss but not how the FIFO appeared to be prematurely
+full. A possible explanation is that a FIFO write was in flight at the
+time the interrupt was raised, but as yet there is no hypothesis as to
+how this might occur.
+
+In the absence of a clear understanding of the failure mechanism, avoid
+the problem by checking the FIFO levels before writing the last byte of
+the group, which will have minimal performance impact.

+Thanks to Gordon and Costas
+
+Avoid dynamic memory allocation for channel lock in USB driver. Thanks ddv2005.
+
+Add NAK holdoff scheme. Enabled by default, disable with dwc_otg.nak_holdoff_enable=0. Thanks gsh
+
+Make sure we wait for the reset to finish
+
+dwc_otg: fix bug in dwc_otg_hcd.c resulting in silent kernel
+	 memory corruption, escalating to OOPS under high USB load.
+
+dwc_otg: Fix unsafe access of QTD during URB enqueue
+
+In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
+transaction could complete almost immediately after the qtd was assigned
+to a host channel during URB enqueue, which meant the qtd pointer was no
+longer valid having been completed and removed. Usually, this resulted in
+an OOPS during URB submission. By predetermining whether transactions
+need to be queued or not, this unsafe pointer access is avoided.
+
+This bug was only evident on the Pi model A where a device was attached
+that had no periodic endpoints (e.g. USB pendrive or some wlan devices).
+
+dwc_otg: Fix incorrect URB allocation error handling
+
+If the memory allocation for a dwc_otg_urb failed, the kernel would OOPS
+because for some reason a member of the *unallocated* struct was set to
+zero. Error handling changed to fail correctly.
+
+dwc_otg: fix potential use-after-free case in interrupt handler
+
+If a transaction had previously aborted, certain interrupts are
+enabled to track error counts and reset where necessary. On IN
+endpoints the host generates an ACK interrupt near-simultaneously
+with completion of transfer. In the case where this transfer had
+previously had an error, this results in a use-after-free on
+the QTD memory space with a 1-byte length being overwritten to
+0x00.
+
+dwc_otg: add handling of SPLIT transaction data toggle errors
+
+Previously a data toggle error on packets from a USB1.1 device behind
+a TT would result in the Pi locking up as the driver never handled
+the associated interrupt. Patch adds basic retry mechanism and
+interrupt acknowledgement to cater for either a chance toggle error or
+for devices that have a broken initial toggle state (FT8U232/FT232BM).
+
+dwc_otg: implement tasklet for returning URBs to usbcore hcd layer
+
+The dwc_otg driver interrupt handler for transfer completion will spend
+a very long time with interrupts disabled when a URB is completed -
+this is because usb_hcd_giveback_urb is called from within the handler
+which for a USB device driver with complicated processing (e.g. webcam)
+will take an exorbitant amount of time to complete. This results in
+missed completion interrupts for other USB packets which lead to them
+being dropped due to microframe overruns.
+
+This patch splits returning the URB to the usb hcd layer into a
+high-priority tasklet. This will have most benefit for isochronous IN
+transfers but will also have incidental benefit where multiple periodic
+devices are active at once.
+
+dwc_otg: fix NAK holdoff and allow on split transactions only
+
+This corrects a bug where if a single active non-periodic endpoint
+had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
+would get skipped and never get queued again. This would result in
+a silent device until error detection (automatic or otherwise) would
+either reset the device or flush and requeue the URBs.
+
+Additionally the NAK holdoff was enabled for all transactions - this
+would potentially stall a HS endpoint for 1ms if a previous error state
+enabled this interrupt and the next response was a NAK. Fix so that
+only split transactions get held off.
+
+dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock held in completion handler
+
+usb_hcd_unlink_urb_from_ep must be called with the HCD lock held.  Calling it
+asynchronously in the tasklet was not safe (regression in
+c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
+
+This change unlinks it from the endpoint prior to queueing it for handling in
+the tasklet, and also adds a check to ensure the urb is OK to be unlinked
+before doing so.
+
+NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
+when a USB device was unplugged/replugged during data transfer.  This effect
+was reproduced using automated USB port power control, hundreds of replug
+events were performed during active transfers to confirm that the problem was
+eliminated.
+
+USB fix using a FIQ to implement split transactions
+
+This commit adds a FIQ implementaion that schedules
+the split transactions using a FIQ so we don't get
+held off by the interrupt latency of Linux
+
+dwc_otg: fix device attributes and avoid kernel warnings on boot
+
+dcw_otg: avoid logging function that can cause panics
+
+See: https://github.com/raspberrypi/firmware/issues/21
+Thanks to cleverca22 for fix
+
+dwc_otg: mask correct interrupts after transaction error recovery
+
+The dwc_otg driver will unmask certain interrupts on a transaction
+that previously halted in the error state in order to reset the
+QTD error count. The various fine-grained interrupt handlers do not
+consider that other interrupts besides themselves were unmasked.
+
+By disabling the two other interrupts only ever enabled in DMA mode
+for this purpose, we can avoid unnecessary function calls in the
+IRQ handler. This will also prevent an unneccesary FIQ interrupt
+from being generated if the FIQ is enabled.
+
+dwc_otg: fiq: prevent FIQ thrash and incorrect state passing to IRQ
+
+In the case of a transaction to a device that had previously aborted
+due to an error, several interrupts are enabled to reset the error
+count when a device responds. This has the side-effect of making the
+FIQ thrash because the hardware will generate multiple instances of
+a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
+on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
+associated interrupts.
+
+Additionally, on non-split transactions make sure that only unmasked
+interrupts are cleared. This caused a hard-to-trigger but serious
+race condition when you had the combination of an endpoint awaiting
+error recovery and a transaction completed on an endpoint - due to
+the sequencing and timing of interrupts generated by the dwc_otg core,
+it was possible to confuse the IRQ handler.
+
+Fix function tracing
+
+dwc_otg: whitespace cleanup in dwc_otg_urb_enqueue
+
+dwc_otg: prevent OOPSes during device disconnects
+
+The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
+access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
+friends does not occur within a critical section and so if a device
+was unplugged during activity there was a high chance that the
+usbcore hub_thread would try to disable the endpoint with partially-
+formed entries in the URB queue. This would result in BUG() or null
+pointer dereferences.
+
+Fix so that access of urb->hcpriv, enqueuing to the hardware and
+adding to usbcore endpoint URB lists is contained within a single
+critical section.
+
+dwc_otg: prevent BUG() in TT allocation if hub address is > 16
+
+A fixed-size array is used to track TT allocation. This was
+previously set to 16 which caused a crash because
+dwc_otg_hcd_allocate_port would read past the end of the array.
+
+This was hit if a hub was plugged in which enumerated as addr > 16,
+due to previous device resets or unplugs.
+
+Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
+to a large size if 128 hub addresses are supported. This field is
+for debug only for tracking which frame an allocate happened in.
+
+dwc_otg: make channel halts with unknown state less damaging
+
+If the IRQ received a channel halt interrupt through the FIQ
+with no other bits set, the IRQ would not release the host
+channel and never complete the URB.
+
+Add catchall handling to treat as a transaction error and retry.
+
+dwc_otg: fiq_split: use TTs with more granularity
+
+This fixes certain issues with split transaction scheduling.
+
+- Isochronous multi-packet OUT transactions now hog the TT until
+  they are completed - this prevents hubs aborting transactions
+  if they get a periodic start-split out-of-order
+- Don't perform TT allocation on non-periodic endpoints - this
+  allows simultaneous use of the TT's bulk/control and periodic
+  transaction buffers
+
+This commit will mainly affect USB audio playback.
+
+dwc_otg: fix potential sleep while atomic during urb enqueue
+
+Fixes a regression introduced with eb1b482a. Kmalloc called from
+dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
+the GPF_ATOMIC flag set. Force this flag when inside the larger
+critical section.
+
+dwc_otg: make fiq_split_enable imply fiq_fix_enable
+
+Failing to set up the FIQ correctly would result in
+"IRQ 32: nobody cared" errors in dmesg.
+
+dwc_otg: prevent crashes on host port disconnects
+
+Fix several issues resulting in crashes or inconsistent state
+if a Model A root port was disconnected.
+
+- Clean up queue heads properly in kill_urbs_in_qh_list by
+  removing the empty QHs from the schedule lists
+- Set the halt status properly to prevent IRQ handlers from
+  using freed memory
+- Add fiq_split related cleanup for saved registers
+- Make microframe scheduling reclaim host channels if
+  active during a disconnect
+- Abort URBs with -ESHUTDOWN status response, informing
+  device drivers so they respond in a more correct fashion
+  and don't try to resubmit URBs
+- Prevent IRQ handlers from attempting to handle channel
+  interrupts if the associated URB was dequeued (and the
+  driver state was cleared)
+
+dwc_otg: prevent leaking URBs during enqueue
+
+A dwc_otg_urb would get leaked if the HCD enqueue function
+failed for any reason. Free the URB at the appropriate points.
+
+dwc_otg: Enable NAK holdoff for control split transactions
+
+Certain low-speed devices take a very long time to complete a
+data or status stage of a control transaction, producing NAK
+responses until they complete internal processing - the USB2.0
+spec limit is up to 500mS. This causes the same type of interrupt
+storm as seen with USB-serial dongles prior to c8edb238.
+
+In certain circumstances, usually while booting, this interrupt
+storm could cause SD card timeouts.
+
+dwc_otg: Fix for occasional lockup on boot when doing a USB reset
+
+dwc_otg: Don't issue traffic to LS devices in FS mode
+
+Issuing low-speed packets when the root port is in full-speed mode
+causes the root port to stop responding. Explicitly fail when
+enqueuing URBs to a LS endpoint on a FS bus.
+
+Fix ARM architecture issue with local_irq_restore()
+
+If local_fiq_enable() is called before a local_irq_restore(flags) where
+the flags variable has the F bit set, the FIQ will be erroneously disabled.
+
+Fixup arch_local_irq_restore to avoid trampling the F bit in CPSR.
+
+Also fix some of the hacks previously implemented for previous dwc_otg

+
+dwc_otg: fiq_fsm: Base commit for driver rewrite
+
+This commit removes the previous FIQ fixes entirely and adds fiq_fsm.
+
+This rewrite features much more complete support for split transactions
+and takes into account several OTG hardware bugs. High-speed
+isochronous transactions are also capable of being performed by fiq_fsm.
+
+All driver options have been removed and replaced with:
+  - dwc_otg.fiq_enable (bool)
+  - dwc_otg.fiq_fsm_enable (bool)
+  - dwc_otg.fiq_fsm_mask (bitmask)
+  - dwc_otg.nak_holdoff (unsigned int)
+
+Defaults are specified such that fiq_fsm behaves similarly to the
+previously implemented FIQ fixes.
+
+fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
+
+If the transfer associated with a QTD failed due to a bus error, the HCD
+would retry the transfer up to 3 times (implementing the USB2.0
+three-strikes retry in software).
+
+Due to the masking mechanism used by fiq_fsm, it is only possible to pass
+a single interrupt through to the HCD per-transfer.
+
+In this instance host channels would fall off the radar because the error
+reset would function, but the subsequent channel halt would be lost.
+
+Push the error count reset into the FIQ handler.
+
+fiq_fsm: Implement timeout mechanism
+
+For full-speed endpoints with a large packet size, interrupt latency
+runs the risk of the FIQ starting a transaction too late in a full-speed
+frame. If the device is still transmitting data when EOF2 for the
+downstream frame occurs, the hub will disable the port. This change is
+not reflected in the hub status endpoint and the device becomes
+unresponsive.
+
+Prevent high-bandwidth transactions from being started too late in a
+frame. The mechanism is not guaranteed: a combination of bit stuffing
+and hub latency may still result in a device overrunning.
+
+fiq_fsm: fix bounce buffer utilisation for Isochronous OUT
+
+Multi-packet isochronous OUT transactions were subject to a few bounday
+bugs. Fix them.
+
+Audio playback is now much more robust: however, an issue stands with
+devices that have adaptive sinks - ALSA plays samples too fast.
+
+dwc_otg: Return full-speed frame numbers in HS mode
+
+The frame counter increments on every *microframe* in high-speed mode.
+Most device drivers expect this number to be in full-speed frames - this
+caused considerable confusion to e.g. snd_usb_audio which uses the
+frame counter to estimate the number of samples played.
+
+fiq_fsm: save PID on completion of interrupt OUT transfers
+
+Also add edge case handling for interrupt transports.
+
+Note that for periodic split IN, data toggles are unimplemented in the
+OTG host hardware - it unconditionally accepts any PID.
+
+fiq_fsm: add missing case for fiq_fsm_tt_in_use()
+
+Certain combinations of bitrate and endpoint activity could
+result in a periodic transaction erroneously getting started
+while the previous Isochronous OUT was still active.
+
+fiq_fsm: clear hcintmsk for aborted transactions
+
+Prevents the FIQ from erroneously handling interrupts
+on a timed out channel.
+
+fiq_fsm: enable by default
+
+fiq_fsm: fix dequeues for non-periodic split transactions
+
+If a dequeue happened between the SSPLIT and CSPLIT phases of the
+transaction, the HCD would never receive an interrupt.
+
+fiq_fsm: Disable by default
+
+fiq_fsm: Handle HC babble errors
+
+The HCTSIZ transfer size field raises a babble interrupt if
+the counter wraps. Handle the resulting interrupt in this case.
+
+dwc_otg: fix interrupt registration for fiq_enable=0
+
+Additionally make the module parameter conditional for wherever
+hcd->fiq_state is touched.
+
+fiq_fsm: Enable by default
+
+dwc_otg: Fix various issues with root port and transaction errors
+
+Process the host port interrupts correctly (and don't trample them).
+Root port hotplug now functional again.
+
+Fix a few thinkos with the transaction error passthrough for fiq_fsm.
+
+fiq_fsm: Implement hack for Split Interrupt transactions
+
+Hubs aren't too picky about which endpoint we send Control type split
+transactions to. By treating Interrupt transfers as Control, it is
+possible to use the non-periodic queue in the OTG core as well as the
+non-periodic FIFOs in the hub itself. This massively reduces the
+microframe exclusivity/contention that periodic split transactions
+otherwise have to enforce.
+
+It goes without saying that this is a fairly egregious USB specification
+violation, but it works.
+
+Original idea by Hans Petter Selasky @ FreeBSD.org.
+
+dwc_otg: FIQ support on SMP. Set up FIQ stack and handler on Core 0 only.
+
+dwc_otg: introduce fiq_fsm_spin(un|)lock()
+
+SMP safety for the FIQ relies on register read-modify write cycles being
+completed in the correct order. Several places in the DWC code modify
+registers also touched by the FIQ. Protect these by a bare-bones lock
+mechanism.
+
+This also makes it possible to run the FIQ and IRQ handlers on different
+cores.
+
+fiq_fsm: fix build on bcm2708 and bcm2709 platforms
+
+dwc_otg: put some barriers back where they should be for UP
+
+bcm2709/dwc_otg: Setup FIQ on core 1 if >1 core active
+
+dwc_otg: fixup read-modify-write in critical paths
+
+Be more careful about read-modify-write on registers that the FIQ
+also touches.
+
+Guard fiq_fsm_spin_lock with fiq_enable check
+
+fiq_fsm: Falling out of the state machine isn't fatal
+
+This edge case can be hit if the port is disabled while the FIQ is
+in the middle of a transaction. Make the effects less severe.
+
+Also get rid of the useless return value.

+
+Commit 6ce0d20 changes dma_to_virt() which breaks this driver.
+Open code the old dma_to_virt() implementation to work around this.
+
+Limit the use of __bus_to_virt() to cases where transfer_buffer_length
+is set and transfer_buffer is not set. This is done to increase the
+chance that this driver will also work on ARCH_BCM2835.
+
+transfer_buffer should not be NULL if the length is set, but the
+comment in the code indicates that there are situations where this
+might happen. drivers/usb/isp1760/isp1760-hcd.c also has a similar
+comment pointing to a possible: 'usb storage / SCSI bug'.

+
+fiq_fsm: Use correct states when starting isoc OUT transfers
+
+In fiq_fsm_start_next_periodic() if an isochronous OUT transfer
+was selected, no regard was given as to whether this was a single-packet
+transfer or a multi-packet staged transfer.
+
+For single-packet transfers, this had the effect of repeatedly sending
+OUT packets with bogus data and lengths.
+
+Eventually if the channel was repeatedly enabled enough times, this
+would lock up the OTG core and no further bus transfers would happen.
+
+Set the FSM state up properly if we select a single-packet transfer.

+
+dwc_otg: make nak_holdoff work as intended with empty queues
+
+If URBs reading from non-periodic split endpoints were dequeued and
+the last transfer from the endpoint was a NAK handshake, the resulting
+qh->nak_frame value was stale which would result in unnecessarily long
+polling intervals for the first subsequent transfer with a fresh URB.
+
+Fixup qh->nak_frame in dwc_otg_hcd_urb_dequeue and also guard against
+a case where a single URB is submitted to the endpoint, a NAK was
+received on the transfer immediately prior to receiving data and the
+device subsequently resubmits another URB past the qh->nak_frame interval.
+
+Fixes https://github.com/raspberrypi/linux/issues/1709
+
+dwc_otg: fix split transaction data toggle handling around dequeues
+
+See https://github.com/raspberrypi/linux/issues/1709
+
+Fix several issues regarding endpoint state when URBs are dequeued
+- If the HCD is disconnected, flush FIQ-enabled channels properly
+- Save the data toggle state for bulk endpoints if the last transfer
+  from an endpoint where URBs were dequeued returned a data packet
+- Reset hc->start_pkt_count properly in assign_and_init_hc()
+
+dwc_otg: fix several potential crash sources
+
+On root port disconnect events, the host driver state is cleared and
+in-progress host channels are forcibly stopped. This doesn't play
+well with the FIQ running in the background, so:
+- Guard the disconnect callback with both the host spinlock and FIQ
+  spinlock
+- Move qtd dereference in dwc_otg_handle_hc_fsm() after the early-out
+  so we don't dereference a qtd that has gone away
+- Turn catch-all BUG()s in dwc_otg_handle_hc_fsm() into warnings.
+
+dwc_otg: delete hcd->channel_lock
+
+The lock serves no purpose as it is only held while the HCD spinlock
+is already being held.
+
+dwc_otg: remove unnecessary dma-mode channel halts on disconnect interrupt
+
+Host channels are already halted in kill_urbs_in_qh_list() with the
+subsequent interrupt processing behaving as if the URB was dequeued
+via HCD callback.
+
+There's no need to clobber the host channel registers a second time
+as this exposes races between the driver and host channel resulting
+in hcd->free_hc_list becoming corrupted.

+
+dwc_otg: make periodic scheduling behave properly for FS buses
+
+If the root port is in full-speed mode, transfer times at 12mbit/s
+would be calculated but matched against high-speed quotas.
+
+Reinitialise hcd->frame_usecs[i] on each port enable event so that
+full-speed bandwidth can be tracked sensibly.
+
+Also, don't bother using the FIQ for transfers when in full-speed
+mode - at the slower bus speed, interrupt frequency is reduced by
+an order of magnitude.

+dwc_otg: add module parameter int_ep_interval_min

+Add a module parameter (defaulting to ignored) that clamps the polling rate

+dwc_otg: fiq_fsm: Add non-periodic TT exclusivity constraints

+usb: dwc_otg: fix memory corruption in dwc_otg driver

+[Upstream commit 51b1b6491752ac066ee8d32cc66042fcc955fef6]
+
+The move from the staging tree to the main tree exposed a
+longstanding memory corruption bug in the dwc2 driver. The
+reordering of the driver initialization caused the dwc2 driver
+to corrupt the initialization data of the sdhci driver on the
+Raspberry Pi platform, which made the bug show up.
+
+The error is in calling to_usb_device(hsotg->dev), since ->dev
+is not a member of struct usb_device. The easiest fix is to
+just remove the offending code, since it is not really needed.

+in the handler itself are not required.
+
+On BCM2836 and BCM2837 the barrier is not strictly required due to
+differences in how the peripheral bus is implemented, but having
+arch-specific handlers that introduce different latencies is risky.

+dwc_otg: initialise sched_frame for periodic QHs that were parked
+
+If a periodic QH has no remaining QTDs, then it is removed from all
+periodic schedules. When re-adding, initialise the sched_frame and
+start_split_frame from the current value of the frame counter.

+dwc_otg: Minimise header and fix build warnings
+
+Delete a large amount of unused declaration from "usb.h", some of which
+were causing build warnings, and get the module building cleanly.

+
+dwc-otg: fix clang -Wignored-attributes warning
+
+warning: attribute declaration must precede definition
+
+dwc-otg: fix clang -Wsometimes-uninitialized warning
+
+warning: variable 'retval' is used uninitialized whenever 'if' condition is false
+
+dwc-otg: fix clang -Wpointer-bool-conversion warning
+
+warning: address of array 'desc->wMaxPacketSize' will always evaluate to 'true'
+
+The wMaxPacketSize field is actually a two element array which content should
+be accessed via the UGETW macro.
+
+dwc_otg: fix an undeclared variable
+Replace an undeclared variable used by DWC_DEBUGPL with the real endpoint address. DWC_DEBUGPL does nothing with DEBUG undefined so it did not go wrong before.

+
+dwc_otg: Update NetBSD usb.h header licence
+
+NetBSD have changed their licensing requirements such that the 2-clause
+licence is preferred. Update usb.h in the downstream dwc_otg code
+accordingly.
+
+See https://www.netbsd.org/about/redistribution.html for more
+information.

+dwc_otg: pay attention to qh->interval when rescheduling periodic queues
+
+A regression introduced in https://github.com/raspberrypi/linux/pull/3887
+meant that if the newly scheduled transfer immediately returned data, and
+the driver resubmitted a single URB after every transfer, then the effective
+polling interval would end up being approx 1ms.
+
+Use the larger of SCHEDULE_SLOP or the configured endpoint interval.

++ * The File-backed Storage Gadget acts as a USB Mass Storage device,
++ * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
++ * to providing an example of a genuinely useful gadget driver for a USB
++ * device, it also illustrates a technique of double-buffering for increased
++ * throughput.  Last but not least, it gives an easy way to probe the
++ * behavior of the Mass Storage drivers in a USB host.
++ *
++ * Backing storage is provided by a regular file or a block device, specified
++ * by the "file" module parameter.  Access can be limited to read-only by
++ * setting the optional "ro" module parameter.  (For CD-ROM emulation,
++ * access is always read-only.)  The gadget will indicate that it has
++ * removable media if the optional "removable" module parameter is set.
++ *
++ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
++ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
++ * by the optional "transport" module parameter.  It also supports the
++ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
++ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
++ * the optional "protocol" module parameter.  In addition, the default
++ * Vendor ID, Product ID, release number and serial number can be overridden.
++ *
++ * There is support for multiple logical units (LUNs), each of which has
++ * its own backing file.  The number of LUNs can be set using the optional
++ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
++ * files are specified using comma-separated lists for "file" and "ro".
++ * The default number of LUNs is taken from the number of "file" elements;
++ * it is 1 if "file" is not given.  If "removable" is not set then a backing
++ * file must be specified for each LUN.  If it is set, then an unspecified
++ * or empty backing filename means the LUN's medium is not loaded.  Ideally
++ * each LUN would be settable independently as a disk drive or a CD-ROM
++ * drive, but currently all LUNs have to be the same type.  The CD-ROM
++ * emulation includes a single data track and no audio tracks; hence there
++ * need be only one backing file per LUN.
++ *
++ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
++ * needed (an interrupt-out endpoint is also needed for CBI).  The memory
++ * requirement amounts to two 16K buffers, size configurable by a parameter.
++ * Support is included for both full-speed and high-speed operation.
++ *
++ * Note that the driver is slightly non-portable in that it assumes a
++ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
++ * interrupt-in endpoints.  With most device controllers this isn't an
++ * issue, but there may be some with hardware restrictions that prevent
++ * a buffer from being used by more than one endpoint.
++ *
++ * Module options:
++ *
++ *	file=filename[,filename...]
++ *				Required if "removable" is not set, names of
++ *					the files or block devices used for
++ *					backing storage
++ *	serial=HHHH...		Required serial number (string of hex chars)
++ *	ro=b[,b...]		Default false, booleans for read-only access
++ *	removable		Default false, boolean for removable media
++ *	luns=N			Default N = number of filenames, number of
++ *					LUNs to support
++ *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
++ *					in SCSI WRITE(10,12) commands
++ *	stall			Default determined according to the type of
++ *					USB device controller (usually true),
++ *					boolean to permit the driver to halt
++ *					bulk endpoints
++ *	cdrom			Default false, boolean for whether to emulate
++ *					a CD-ROM drive
++ *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
++ *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
++ *					ATAPI, QIC, UFI, 8070, or SCSI;
++ *					also 1 - 6)
++ *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
++ *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
++ *	release=0xRRRR		Override the USB release number (bcdDevice)
++ *	buflen=N		Default N=16384, buffer size used (will be
++ *					rounded down to a multiple of
++ *					PAGE_CACHE_SIZE)
++ *
++ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
++ * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
++ * default values are used for everything else.
++ *
++ * The pathnames of the backing files and the ro settings are available in
++ * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
++ * the gadget's sysfs directory.  If the "removable" option is set, writing to
++ * these files will simulate ejecting/loading the medium (writing an empty
++ * line means eject) and adjusting a write-enable tab.  Changes to the ro
++ * setting are not allowed when the medium is loaded or if CD-ROM emulation
++ * is being used.
++ *
++ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
++ * The driver's SCSI command interface was based on the "Information
++ * technology - Small Computer System Interface - 2" document from
++ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
++ * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
++ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
++ * "Universal Serial Bus Mass Storage Class UFI Command Specification"
++ * document, Revision 1.0, December 14, 1998, available at
++ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.
++ */
++
++
++/*
++ *				Driver Design
++ *
++ * The FSG driver is fairly straightforward.  There is a main kernel
++ * thread that handles most of the work.  Interrupt routines field
++ * callbacks from the controller driver: bulk- and interrupt-request
++ * completion notifications, endpoint-0 events, and disconnect events.
++ * Completion events are passed to the main thread by wakeup calls.  Many
++ * ep0 requests are handled at interrupt time, but SetInterface,
++ * SetConfiguration, and device reset requests are forwarded to the
++ * thread in the form of "exceptions" using SIGUSR1 signals (since they
++ * should interrupt any ongoing file I/O operations).
++ *
++ * The thread's main routine implements the standard command/data/status
++ * parts of a SCSI interaction.  It and its subroutines are full of tests
++ * for pending signals/exceptions -- all this polling is necessary since
++ * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
++ * indication that the driver really wants to be running in userspace.)
++ * An important point is that so long as the thread is alive it keeps an
++ * open reference to the backing file.  This will prevent unmounting
++ * the backing file's underlying filesystem and could cause problems
++ * during system shutdown, for example.  To prevent such problems, the
++ * thread catches INT, TERM, and KILL signals and converts them into
++ * an EXIT exception.
++ *
++ * In normal operation the main thread is started during the gadget's
++ * fsg_bind() callback and stopped during fsg_unbind().  But it can also
++ * exit when it receives a signal, and there's no point leaving the
++ * gadget running when the thread is dead.  So just before the thread
++ * exits, it deregisters the gadget driver.  This makes things a little
++ * tricky: The driver is deregistered at two places, and the exiting
++ * thread can indirectly call fsg_unbind() which in turn can tell the
++ * thread to exit.  The first problem is resolved through the use of the
++ * REGISTERED atomic bitflag; the driver will only be deregistered once.
++ * The second problem is resolved by having fsg_unbind() check
++ * fsg->state; it won't try to stop the thread if the state is already
++ * FSG_STATE_TERMINATED.
++ *
++ * To provide maximum throughput, the driver uses a circular pipeline of
++ * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
++ * arbitrarily long; in practice the benefits don't justify having more
++ * than 2 stages (i.e., double buffering).  But it helps to think of the
++ * pipeline as being a long one.  Each buffer head contains a bulk-in and
++ * a bulk-out request pointer (since the buffer can be used for both
++ * output and input -- directions always are given from the host's
++ * point of view) as well as a pointer to the buffer and various state
++ * variables.
++ *
++ * Use of the pipeline follows a simple protocol.  There is a variable
++ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
++ * At any time that buffer head may still be in use from an earlier
++ * request, so each buffer head has a state variable indicating whether
++ * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
++ * buffer head to be EMPTY, filling the buffer either by file I/O or by
++ * USB I/O (during which the buffer head is BUSY), and marking the buffer
++ * head FULL when the I/O is complete.  Then the buffer will be emptied
++ * (again possibly by USB I/O, during which it is marked BUSY) and
++ * finally marked EMPTY again (possibly by a completion routine).
++ *
++ * A module parameter tells the driver to avoid stalling the bulk
++ * endpoints wherever the transport specification allows.  This is
++ * necessary for some UDCs like the SuperH, which cannot reliably clear a
++ * halt on a bulk endpoint.  However, under certain circumstances the
++ * Bulk-only specification requires a stall.  In such cases the driver
++ * will halt the endpoint and set a flag indicating that it should clear
++ * the halt in software during the next device reset.  Hopefully this
++ * will permit everything to work correctly.  Furthermore, although the
++ * specification allows the bulk-out endpoint to halt when the host sends
++ * too much data, implementing this would cause an unavoidable race.
++ * The driver will always use the "no-stall" approach for OUT transfers.
++ *
++ * One subtle point concerns sending status-stage responses for ep0
++ * requests.  Some of these requests, such as device reset, can involve
++ * interrupting an ongoing file I/O operation, which might take an
++ * arbitrarily long time.  During that delay the host might give up on
++ * the original ep0 request and issue a new one.  When that happens the
++ * driver should not notify the host about completion of the original
++ * request, as the host will no longer be waiting for it.  So the driver
++ * assigns to each ep0 request a unique tag, and it keeps track of the
++ * tag value of the request associated with a long-running exception
++ * (device-reset, interface-change, or configuration-change).  When the
++ * exception handler is finished, the status-stage response is submitted
++ * only if the current ep0 request tag is equal to the exception request
++ * tag.  Thus only the most recently received ep0 request will get a
++ * status-stage response.
++ *
++ * Warning: This driver source file is too long.  It ought to be split up
++ * into a header file plus about 3 separate .c files, to handle the details
++ * of the Gadget, USB Mass Storage, and SCSI protocols.

++
++dwc_read_reg32() and friends now take an additional parameter, a pointer to an
++IO context struct. The IO context struct should live in an os-dependent struct
++in your driver. As an example, the dwc_usb3 driver has an os-dependent struct
++named 'os_dep' embedded in the main device struct. So there these calls look
++like this:
++
++	dwc_read_reg32(&usb3_dev->os_dep.ioctx, &pcd->dev_global_regs->dcfg);
++
++	dwc_write_reg32(&usb3_dev->os_dep.ioctx,
++			&pcd->dev_global_regs->dcfg, 0);
++
++Note that for the existing Linux driver ports, it is not necessary to actually
++define the 'ioctx' member in the os-dependent struct. Since Linux does not
++require an IO context, its macros for dwc_read_reg32() and friends do not
++use the context pointer, so it is optimized away by the compiler. But it is
++necessary to add the pointer parameter to all of the call sites, to be ready
++for any future ports (such as FreeBSD) which do require an IO context.
++
++
++Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now
++take an additional parameter, a pointer to a memory context. Examples:
++
++	addr = dwc_alloc(&usb3_dev->os_dep.memctx, size);
++
++	dwc_free(&usb3_dev->os_dep.memctx, addr);
++
++Again, for the Linux ports, it is not necessary to actually define the memctx
++member, but it is necessary to add the pointer parameter to all of the call
++sites.
++
++
++Same for dwc_dma_alloc() and dwc_dma_free(). Examples:
++
++	virt_addr = dwc_dma_alloc(&usb3_dev->os_dep.dmactx, size, &phys_addr);
++
++	dwc_dma_free(&usb3_dev->os_dep.dmactx, size, virt_addr, phys_addr);
++
++
++Same for dwc_mutex_alloc() and dwc_mutex_free(). Examples:
++
++	mutex = dwc_mutex_alloc(&usb3_dev->os_dep.mtxctx);
++
++	dwc_mutex_free(&usb3_dev->os_dep.mtxctx, mutex);
++
++
++Same for dwc_spinlock_alloc() and dwc_spinlock_free(). Examples:
++
++	lock = dwc_spinlock_alloc(&usb3_dev->osdep.splctx);
++
++	dwc_spinlock_free(&usb3_dev->osdep.splctx, lock);
++
++
++Same for dwc_timer_alloc(). Example:
++
++	timer = dwc_timer_alloc(&usb3_dev->os_dep.tmrctx, "dwc_usb3_tmr1",
++				cb_func, cb_data);
++
++
++Same for dwc_waitq_alloc(). Example:
++
++	waitq = dwc_waitq_alloc(&usb3_dev->os_dep.wtqctx);
++
++
++Same for dwc_thread_run(). Example:
++
++	thread = dwc_thread_run(&usb3_dev->os_dep.thdctx, func,
++				"dwc_usb3_thd1", data);
++
++
++Same for dwc_workq_alloc(). Example:
++
++	workq = dwc_workq_alloc(&usb3_dev->osdep.wkqctx, "dwc_usb3_wkq1");
++
++
++Same for dwc_task_alloc(). Example:
++
++	task = dwc_task_alloc(&usb3_dev->os_dep.tskctx, "dwc_usb3_tsk1",
++			      cb_func, cb_data);
++
++
++In addition to the context pointer additions, a few core functions have had
++other changes made to their parameters:
++
++The 'flags' parameter to dwc_spinlock_irqsave() and dwc_spinunlock_irqrestore()
++has been changed from a uint64_t to a dwc_irqflags_t.
++
++dwc_thread_should_stop() now takes a 'dwc_thread_t *' parameter, because the
++FreeBSD equivalent of that function requires it.
++
++And, in addition to the context pointer, dwc_task_alloc() also adds a
++'char *name' parameter, to be consistent with dwc_thread_run() and
++dwc_workq_alloc(), and because the FreeBSD equivalent of that function
++requires a unique name.
++
++
++Here is a complete list of the core functions that now take a pointer to a
++context as their first parameter:
++
++	dwc_read_reg32
++	dwc_read_reg64
++	dwc_write_reg32
++	dwc_write_reg64
++	dwc_modify_reg32
++	dwc_modify_reg64
++	dwc_alloc
++	dwc_alloc_atomic
++	dwc_strdup
++	dwc_free
++	dwc_dma_alloc
++	dwc_dma_free
++	dwc_mutex_alloc
++	dwc_mutex_free
++	dwc_spinlock_alloc
++	dwc_spinlock_free
++	dwc_timer_alloc
++	dwc_waitq_alloc
++	dwc_thread_run
++	dwc_workq_alloc
++	dwc_task_alloc     Also adds a 'char *name' as its 2nd parameter
++
++And here are the core functions that have other changes to their parameters:
++
++	dwc_spinlock_irqsave      'flags' param is now a 'dwc_irqflags_t *'
++	dwc_spinunlock_irqrestore 'flags' param is now a 'dwc_irqflags_t'
++	dwc_thread_should_stop    Adds a 'dwc_thread_t *' parameter
++
++
++
++The changes to the core functions also require some of the other library
++functions to change:
++
++	dwc_cc_if_alloc() and dwc_cc_if_free() now take a 'void *memctx'
++	(for memory allocation) as the 1st param and a 'void *mtxctx'
++	(for mutex allocation) as the 2nd param.
++
++	dwc_cc_clear(), dwc_cc_add(), dwc_cc_change(), dwc_cc_remove(),
++	dwc_cc_data_for_save(), and dwc_cc_restore_from_data() now take a
++	'void *memctx' as the 1st param.
++
++	dwc_dh_modpow(), dwc_dh_pk(), and dwc_dh_derive_keys() now take a
++	'void *memctx' as the 1st param.
++
++	dwc_modpow() now takes a 'void *memctx' as the 1st param.
++
++	dwc_alloc_notification_manager() now takes a 'void *memctx' as the
++	1st param and a 'void *wkqctx' (for work queue allocation) as the 2nd
++	param, and also now returns an integer value that is non-zero if
++	allocation of its data structures or work queue fails.
++
++	dwc_register_notifier() now takes a 'void *memctx' as the 1st param.
++
++	dwc_memory_debug_start() now takes a 'void *mem_ctx' as the first
++	param, and also now returns an integer value that is non-zero if
++	allocation of its data structures fails.
++
++
++
++Other miscellaneous changes:
++
++The DEBUG_MEMORY and DEBUG_REGS #define's have been renamed to
++DWC_DEBUG_MEMORY and DWC_DEBUG_REGS.
++
++The following #define's have been added to allow selectively compiling library
++features:
++
++	DWC_CCLIB
++	DWC_CRYPTOLIB
++	DWC_NOTIFYLIB
++	DWC_UTFLIB
++
++A DWC_LIBMODULE #define has also been added. If this is not defined, then the
++module code in dwc_common_linux.c is not compiled in. This allows linking the
++library code directly into a driver module, instead of as a standalone module.

++ */
++
++/*
++ * This file defines five types of data structures: singly-linked lists,
++ * lists, simple queues, tail queues, and circular queues.
++ *
++ *
++ * A singly-linked list is headed by a single forward pointer. The elements
++ * are singly linked for minimum space and pointer manipulation overhead at
++ * the expense of O(n) removal for arbitrary elements. New elements can be
++ * added to the list after an existing element or at the head of the list.
++ * Elements being removed from the head of the list should use the explicit
++ * macro for this purpose for optimum efficiency. A singly-linked list may
++ * only be traversed in the forward direction.  Singly-linked lists are ideal
++ * for applications with large datasets and few or no removals or for
++ * implementing a LIFO queue.
++ *
++ * A list is headed by a single forward pointer (or an array of forward
++ * pointers for a hash table header). The elements are doubly linked
++ * so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before
++ * or after an existing element or at the head of the list. A list
++ * may only be traversed in the forward direction.
++ *
++ * A simple queue is headed by a pair of pointers, one the head of the
++ * list and the other to the tail of the list. The elements are singly
++ * linked to save space, so elements can only be removed from the
++ * head of the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the
++ * list. A simple queue may only be traversed in the forward direction.
++ *
++ * A tail queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or
++ * after an existing element, at the head of the list, or at the end of
++ * the list. A tail queue may be traversed in either direction.
++ *
++ * A circle queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the list.
++ * A circle queue may be traversed in either direction, but has a more
++ * complex end of list detection.
++ *
++ * For details on the use of these macros, see the queue(3) manual page.

++/** @file
++ *
++ * A simple implementation of the Observer pattern.  Any "module" can
++ * register as an observer or notifier.  The notion of "module" is abstract and
++ * can mean anything used to identify either an observer or notifier.  Usually
++ * it will be a pointer to a data structure which contains some state, ie an
++ * object.
++ *
++ * Before any notifiers can be added, the global notification manager must be
++ * brought up with dwc_alloc_notification_manager().
++ * dwc_free_notification_manager() will bring it down and free all resources.
++ * These would typically be called upon module load and unload.  The
++ * notification manager is a single global instance that handles all registered
++ * observable modules and observers so this should be done only once.
++ *
++ * A module can be observable by using Notifications to publicize some general
++ * information about it's state or operation.  It does not care who listens, or
++ * even if anyone listens, or what they do with the information.  The observable
++ * modules do not need to know any information about it's observers or their
++ * interface, or their state or data.
++ *
++ * Any module can register to emit Notifications.  It should publish a list of
++ * notifications that it can emit and their behavior, such as when they will get
++ * triggered, and what information will be provided to the observer.  Then it
++ * should register itself as an observable module. See dwc_register_notifier().
++ *
++ * Any module can observe any observable, registered module, provided it has a
++ * handle to the other module and knows what notifications to observe.  See
++ * dwc_add_observer().
++ *
++ * A function of type dwc_notifier_callback_t is called whenever a notification
++ * is triggered with one or more observers observing it.  This function is
++ * called in it's own process so it may sleep or block if needed.  It is
++ * guaranteed to be called sometime after the notification has occurred and will
++ * be called once per each time the notification is triggered.  It will NOT be
++ * called in the same process context used to trigger the notification.
++ *
++ * @section Limitiations
++ *
++ * Keep in mind that Notifications that can be triggered in rapid sucession may
++ * schedule too many processes too handle.  Be aware of this limitation when
++ * designing to use notifications, and only add notifications for appropriate
++ * observable information.
++ *
++ * Also Notification callbacks are not synchronous.  If you need to synchronize
++ * the behavior between module/observer you must use other means.  And perhaps
++ * that will mean Notifications are not the proper solution.

++/* @mainpage DWC Portability and Common Library
++ *
++ * This is the documentation for the DWC Portability and Common Library.
++ *
++ * @section intro Introduction
++ *
++ * The DWC Portability library consists of wrapper calls and data structures to
++ * all low-level functions which are typically provided by the OS.  The WUDEV
++ * driver uses only these functions.  In order to port the WUDEV driver, only
++ * the functions in this library need to be re-implemented, with the same
++ * behavior as documented here.
++ *
++ * The Common library consists of higher level functions, which rely only on
++ * calling the functions from the DWC Portability library.  These common
++ * routines are shared across modules.  Some of the common libraries need to be
++ * used directly by the driver programmer when porting WUDEV.  Such as the
++ * parameter and notification libraries.
++ *
++ * @section low Portability Library OS Wrapper Functions
++ *
++ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
++ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC().  All of
++ * these functions are included in the dwc_os.h file.
++ *
++ * There are many functions here covering a wide array of OS services.  Please
++ * see dwc_os.h for details, and implementation notes for each function.
++ *
++ * @section common Common Library Functions
++ *
++ * Any function starting with dwc and in all lowercase is a common library
++ * routine.  These functions have a portable implementation and do not need to
++ * be reimplemented when porting.  The common routines can be used by any
++ * driver, and some must be used by the end user to control the drivers.  For
++ * example, you must use the Parameter common library in order to set the
++ * parameters in the WUDEV module.
++ *
++ * The common libraries consist of the following:
++ *
++ * - Connection Contexts - Used internally and can be used by end-user.  See dwc_cc.h
++ * - Parameters - Used internally and can be used by end-user.  See dwc_params.h
++ * - Notifications - Used internally and can be used by end-user.  See dwc_notifier.h
++ * - Lists - Used internally and can be used by end-user.  See dwc_list.h
++ * - Memory Debugging - Used internally and can be used by end-user.  See dwc_os.h
++ * - Modpow - Used internally only.  See dwc_modpow.h
++ * - DH - Used internally only.  See dwc_dh.h
++ * - Crypto - Used internally only.  See dwc_crypto.h
++ *
++ *
++ * @section prereq Prerequistes For dwc_os.h
++ * @subsection types Data Types
++ *
++ * The dwc_os.h file assumes that several low-level data types are pre defined for the
++ * compilation environment.  These data types are:
++ *
++ * - uint8_t - unsigned 8-bit data type
++ * - int8_t - signed 8-bit data type
++ * - uint16_t - unsigned 16-bit data type
++ * - int16_t - signed 16-bit data type
++ * - uint32_t - unsigned 32-bit data type
++ * - int32_t - signed 32-bit data type
++ * - uint64_t - unsigned 64-bit data type
++ * - int64_t - signed 64-bit data type
++ *
++ * Ensure that these are defined before using dwc_os.h.  The easiest way to do
++ * that is to modify the top of the file to include the appropriate header.
++ * This is already done for the Linux environment.  If the DWC_LINUX macro is
++ * defined, the correct header will be added.  A standard header <stdint.h> is
++ * also used for environments where standard C headers are available.
++ *
++ * @subsection stdarg Variable Arguments
++ *
++ * Variable arguments are provided by a standard C header <stdarg.h>.  it is
++ * available in Both the Linux and ANSI C enviornment.  An equivalent must be
++ * provided in your enviornment in order to use dwc_os.h with the debug and
++ * tracing message functionality.
++ *
++ * @subsection thread Threading
++ *
++ * WUDEV Core must be run on an operating system that provides for multiple
++ * threads/processes.  Threading can be implemented in many ways, even in
++ * embedded systems without an operating system.  At the bare minimum, the
++ * system should be able to start any number of processes at any time to handle
++ * special work.  It need not be a pre-emptive system.  Process context can
++ * change upon a call to a blocking function.  The hardware interrupt context
++ * that calls the module's ISR() function must be differentiable from process
++ * context, even if your processes are impemented via a hardware interrupt.
++ * Further locking mechanism between process must exist (or be implemented), and
++ * process context must have a way to disable interrupts for a period of time to
++ * lock them out.  If all of this exists, the functions in dwc_os.h related to
++ * threading should be able to be implemented with the defined behavior.
++ *

++ *
++ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
++ * affect most of the driver.
++ *
++ * Use it with the Linux host/master side "usbtest" driver to get a basic
++ * functional test of your device-side usb stack, or with "usb-skeleton".
++ *
++ * It supports two similar configurations.  One sinks whatever the usb host
++ * writes, and in return sources zeroes.  The other loops whatever the host
++ * writes back, so the host can read it.  Module options include:
++ *
++ *   buflen=N		default N=4096, buffer size used
++ *   qlen=N		default N=32, how many buffers in the loopback queue
++ *   loopdefault	default false, list loopback config first
++ *
++ * Many drivers will only have one configuration, letting them be much
++ * simpler if they also don't support high speed operation (like this
++ * driver does).

++ * The Core Interface Layer provides basic services for accessing and
++ * managing the DWC_otg hardware. These services are used by both the
++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.
++ * - The OS services used will be abstracted by using inline functions
++ *	 or macros.

++ *
++ * This module also defines a data structure for the dwc_otg_driver, which is

++ * structures allow the OTG driver to comply with the standard Linux driver
++ * model in which devices and drivers are registered with a bus driver. This
++ * has the benefit that Linux can expose attributes of the driver and device
++ * in its special sysfs file system. Users can then read or write files in
++ * this file system to perform diagnostics on the driver components or the

++ * This FIQ implements functionality that performs split transactions on
++ * the dwc_otg hardware without any outside intervention. A split transaction
++ * is "queued" by nominating a specific host channel to perform the entirety
++ * of a split transaction. This FIQ will then perform the microframe-precise
++ * scheduling required in each phase of the transaction until completion.
++ *
++ * The FIQ functionality is glued into the Synopsys driver via the entry point
++ * in the FSM enqueue function, and at the exit point in handling a HC interrupt
++ * for a FSM-enabled channel.
++ *
++ * NB: Large parts of this implementation have architecture-specific code.
++ * For porting this functionality to other ARM machines, the minimum is required:
++ * - An interrupt controller allowing the top-level dwc USB interrupt to be routed
++ *   to the FIQ
++ * - A method of forcing a software generated interrupt from FIQ mode that then
++ *   triggers an IRQ entry (with the dwc USB handler called by this IRQ number)
++ * - Guaranteed interrupt routing such that both the FIQ and SGI occur on the same
++ *   processor core - there is no locking between the FIQ and IRQ (aside from
++ *   local_fiq_disable)

++ * @file
++ *
++ * This file contains the data structures for accessing the DWC_otg core registers.
++ *
++ * The application interfaces with the HS OTG core by reading from and
++ * writing to the Control and Status Register (CSR) space through the
++ * AHB Slave interface. These registers are 32 bits wide, and the
++ * addresses are 32-bit-block aligned.
++ * CSRs are classified as follows:
++ * - Core Global Registers
++ * - Device Mode Registers
++ * - Device Global Registers
++ * - Device Endpoint Specific Registers
++ * - Host Mode Registers
++ * - Host Global Registers
++ * - Host Port CSRs
++ * - Host Channel Specific Registers
++ *
++ * Only the Core Global registers can be accessed in both Device and
++ * Host modes. When the HS OTG core is operating in one mode, either
++ * Device or Host, the application must not access registers from the
++ * other mode. When the core switches from one mode to another, the
++ * registers in the new mode of operation must be reprogrammed as they
++ * would be after a power-on reset.

+bcm2708_fb : Implement blanking support using the mailbox property interface
+
+bcm2708_fb: Add pan and vsync controls
+
+bcm2708_fb: DMA acceleration for fb_copyarea
+
+Based on http://www.raspberrypi.org/phpBB3/viewtopic.php?p=62425#p62425
+Also used Simon's dmaer_master module as a reference for tweaking DMA
+settings for better performance.
+
+For now busylooping only. IRQ support might be added later.
+With non-overclocked Raspberry Pi, the performance is ~360 MB/s
+for simple copy or ~260 MB/s for two-pass copy (used when dragging
+windows to the right).
+
+In the case of using DMA channel 0, the performance improves
+to ~440 MB/s.
+
+For comparison, VFP optimized CPU copy can only do ~114 MB/s in
+the same conditions (hindered by reading uncached source buffer).

+
+bcm2708_fb: report number of dma copies
+
+Add a counter (exported via debugfs) reporting the
+number of dma copies that the framebuffer driver
+has done, in order to help evaluate different
+optimization strategies.
+

+
+bcm2708_fb: use IRQ for DMA copies
+
+The copyarea ioctl() uses DMA to speed things along. This
+was busy-waiting for completion. This change supports using
+an interrupt instead for larger transfers. For small
+transfers, busy-waiting is still likely to be faster.

+bcm2708: Make ioctl logging quieter
+
+video: fbdev: bcm2708_fb: Don't panic on error
+
+No need to panic the kernel if the video driver fails.
+Just print a message and return an error.

+
+fbdev: bcm2708_fb: Add ARCH_BCM2835 support
+
+Add Device Tree support.
+Pass the device to dma_alloc_coherent() in order to get the
+correct bus address on ARCH_BCM2835.
+Use the new DMA legacy API header file.
+Including <mach/platform.h> is not necessary.

+BCM270x_DT: Add bcm2708-fb device
+
+Add bcm2708-fb to Device Tree and don't add the
+platform device when booting in DT mode.
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+Cleanup of bcm2708_fb file to kernel coding standards
+
+Some minor change to function - remove a use of
+in_atomic, plus replacing various debug messages
+that manually specify the function name with
+("%s",.__func__)
+
+Signed-off-by: James Hughes <james.hughes@raspberrypi.org>
+
+video: bcm2708_fb: Try allocating on the ARM and passing to VPU
+
+Currently the VPU allocates the contiguous buffer for the
+framebuffer.
+Try an alternate path first where we use dma_alloc_coherent
+and pass the buffer to the VPU. Should the VPU firmware not
+support that path, then free the buffer and revert to the
+old behaviour of using the VPU allocation.

+Subject: [PATCH] fbdev: add FBIOCOPYAREA ioctl
+
+Based on the patch authored by Ali Gholami Rudi at
+    https://lkml.org/lkml/2009/7/13/153
+
+Provide an ioctl for userspace applications, but only if this operation
+is hardware accelerated (otherwide it does not make any sense).
+
+Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com>
+
+bcm2708_fb: Add ioctl for reading gpu memory through dma
+
+video: bcm2708_fb: Add compat_ioctl support.
+
+When using a 64 bit kernel with 32 bit userspace we need
+compat ioctl handling for FBIODMACOPY as one of the
+parameters is a pointer.

+Subject: [PATCH] dmaengine: Add support for BCM2708
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add support for DMA controller of BCM2708 as used in the Raspberry Pi.
+Currently it only supports cyclic DMA.

+
+dmaengine: expand functionality by supporting scatter/gather transfers sdhci-bcm2708 and dma.c: fix for LITE channels
+
+DMA: fix cyclic LITE length overflow bug
+
+dmaengine: bcm2708: Remove chancnt affectations
+
+Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
+chancnt is already filled by dma_async_device_register, which uses the channel
+list to know how much channels there is.
+
+Since it's already filled, we can safely remove it from the drivers' probe
+function.

+
+dmaengine: bcm2708: overwrite dreq only if it is not set
+
+dreq is set when the DMA channel is fetched from Device Tree.
+slave_id is set using dmaengine_slave_config().
+Only overwrite dreq with slave_id if it is not set.
+
+dreq/slave_id in the cyclic DMA case is not touched, because I don't
+have hardware to test with.

+dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
+
+Merge the legacy DMA API driver with bcm2708-dmaengine.
+This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
+driver is also needed).
+
+Changes to the dma.c code:
+- Use BIT() macro.
+- Cutdown some comments to one line.
+- Add mutex to vc_dmaman and use this, since the dev lock is locked
+  during probing of the engine part.
+- Add global g_dmaman variable since drvdata is used by the engine part.
+- Restructure for readability:
+  vc_dmaman_chan_alloc()
+  vc_dmaman_chan_free()
+  bcm_dma_chan_free()
+- Restructure bcm_dma_chan_alloc() to simplify error handling.
+- Use device irq resources instead of hardcoded bcm_dma_irqs table.
+- Remove dev_dmaman_register() and code it directly.
+- Remove dev_dmaman_deregister() and code it directly.
+- Simplify bcm_dmaman_probe() using devm_* functions.
+- Get dmachans from DT if available.
+- Keep 'dma.dmachans' module argument name for backwards compatibility.
+
+Make it available on ARCH_BCM2835 as well.

+dmaengine: bcm2708: set residue_granularity field
+
+bcm2708-dmaengine supports residue reporting at burst level
+but didn't report this via the residue_granularity field.
+
+Without this field set properly we get playback issues with I2S cards.
+
+dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
+
+bcm2708-dmaengine: Use more DMA channels (but not 12)
+
+1) Only the bcm2708_fb drivers uses the legacy DMA API, and
+it requires a BULK-capable channel, so all other types
+(FAST, NORMAL and LITE) can be made available to the regular
+DMA API.
+
+2) DMA channels 11-14 share an interrupt. The driver can't
+handle this, so don't use channels 12-14 (12 was used, probably
+because it appears to have an interrupt, but in reality that
+interrupt is for activity on ANY channel). This may explain
+a lockup encountered when running out of DMA channels.
+
+The combined effect of this patch is to leave 7 DMA channels
+available + channel 0 for bcm2708_fb via the legacy API.
+
+See: https://github.com/raspberrypi/linux/issues/1110

+
+dmaengine: bcm2708: Make legacy API available for bcm2835-dma
+
+bcm2708_fb uses the legacy DMA API, so in order to start using
+bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
+possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().

+dmaengine: bcm2708: Change DT compatible string
+
+Both bcm2835-dma and bcm2708-dmaengine have the same compatible string.
+So change compatible to "brcm,bcm2708-dma".

+
+dmaengine: bcm2708: Remove driver but keep legacy API
+
+Dropping non-DT support means we don't need this driver,

+bcm2708-dmaengine - Fix arm64 portability/build issues
+
+dma-bcm2708: Fix module compilation of CONFIG_DMA_BCM2708
+
+bcm2708-dmaengine.c defines functions like bcm_dma_start which are
+defined as well in dma-bcm2708.h as inline versions when
+CONFIG_DMA_BCM2708 is not defined. This works fine when
+CONFIG_DMA_BCM2708 is built in, but when it is selected as module build
+fails with redefinition errors because in the build system when
+CONFIG_DMA_BCM2708 is selected as module, the macro becomes
+CONFIG_DMA_BCM2708_MODULE.
+
+This patch makes the header use CONFIG_DMA_BCM2708_MODULE too when
+available.

+bcm2708-dmaengine: Use platform_get_irq
+
+The platform driver framework no longer creates IRQ resources for
+platform devices because they are expected to use platform_get_irq.
+This causes the bcm2808_fb acceleration to fail.
+
+Fix the problem by calling platform_get_irq as intended.

+
+mmc: Disable CMD23 transfers on all cards
+
+Pending wire-level investigation of these types of transfers
+and associated errors on bcm2835-mmc, disable for now. Fallback of
+CMD18/CMD25 transfers will be used automatically by the MMC layer.

+
+bcm2835-mmc: Adding overclocking option
+
+Allow a different clock speed to be substitued for a requested 50MHz.
+This option is exposed using the "overclock_50" DT parameter.
+Note that the mmc interface is restricted to EVEN integer divisions of
+250MHz, and the highest sensible option is 63 (250/4 = 62.5), the
+next being 125 (250/2) which is much too high.
+
+Use at your own risk.
+
+bcm2835-mmc: Round up the overclock, so 62 works for 62.5Mhz
+
+Also only warn once for each overclock setting.

+preserved.
+
+bcm2835-mmc: Only claim one DMA channel
+
+With both MMC controllers enabled there are few DMA channels left. The
+bcm2835-mmc driver only uses DMA in one direction at a time, so it
+doesn't need to claim two channels.

+mmc/bcm2835: Recover from MMC_SEND_EXT_CSD
+
+If the user issues an "mmc extcsd read", the SD controller receives
+what it thinks is a SEND_IF_COND command with an unexpected data block.
+The resulting operations leave the FSM stuck in READWAIT, a state which
+persists until the MMC framework resets the controller, by which point
+the root filesystem is likely to have been unmounted.
+
+A less heavyweight solution is to detect the condition and nudge the
+FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
+
+N.B. This workaround was essentially discovered by accident and without
+a full understanding the inner workings of the controller, so it is
+fortunate that the "fix" only modifies error paths.

+bcm2835-mmc: Fix DMA channel leak
+
+The BCM2835 MMC host driver requests a DMA channel on probe but neglects
+to release the channel in the probe error path and on driver unbind.
+
+I'm seeing this happen on every boot of the Compute Module 3: On first
+driver probe, DMA channel 2 is allocated and then leaked with a "could
+not get clk, deferring probe" message. On second driver probe, channel 4
+is allocated.
+
+Fix it.

+
+bcm2835-mmc: Fix struct mmc_host leak on probe
+
+The BCM2835 MMC host driver requests the bus address of the host's
+register map on probe.  If that fails, the driver leaks the struct
+mmc_host allocated earlier.
+
+Fix it.

+
+bcm2835-mmc: Fix duplicate free_irq() on remove
+
+The BCM2835 MMC host driver requests its interrupt as a device-managed
+resource, so the interrupt is automatically freed after the driver is
+unbound.
+
+However on driver unbind, bcm2835_mmc_remove() frees the interrupt
+explicitly to avoid invocation of the interrupt handler after driver
+structures have been torn down.
+
+The interrupt is thus freed twice, leading to a WARN splat in
+__free_irq().  Fix by not requesting the interrupt as a device-managed
+resource.

+
+bcm2835-mmc: Handle mmc_add_host() errors

+handled.  Fix it.

+bcm2835-mmc: Deduplicate reset of driver data on remove

+mmc: sdhci-iproc: Fix vmmc regulators on iProc
+
+The Linux support for controlling card power via regulators appears to

+SD Bus Voltage Select field of the Power Control Register, which
+seems to kill the Arasan/iProc controller - but fortunately there is a
+hook in sdhci_ops to override the behaviour. Borrow the implementation

+Subject: [PATCH] Adding bcm2835-sdhost driver, and an overlay to enable it
+
+BCM2835 has two SD card interfaces. This driver uses the other one.
+
+bcm2835-sdhost: Error handling fix, and code clarification
+
+bcm2835-sdhost: Adding overclocking option
+
+Allow a different clock speed to be substitued for a requested 50MHz.
+This option is exposed using the "overclock_50" DT parameter.
+Note that the sdhost interface is restricted to integer divisions of
+core_freq, and the highest sensible option for a core_freq of 250MHz
+is 84 (250/3 = 83.3MHz), the next being 125 (250/2) which is much too
+high.
+
+Use at your own risk.
+
+bcm2835-sdhost: Round up the overclock, so 62 works for 62.5Mhz
+
+Also only warn once for each overclock setting.
+
+bcm2835-sdhost: Improve error handling and recovery
+
+1) Expose the hw_reset method to the MMC framework, removing many
+   internal calls by the driver.
+
+2) Reduce overclock setting on error.
+
+3) Increase timeout to cope with high capacity cards.
+
+4) Add properties and parameters to control pio_limit and debug.
+
+5) Reduce messages at probe time.
+
+bcm2835-sdhost: Further improve overclock back-off
+
+bcm2835-sdhost: Clear HBLC for PIO mode
+
+Also update pio_limit default in overlay README.
+
+bcm2835-sdhost: Add the ERASE capability
+
+See: https://github.com/raspberrypi/linux/issues/1076
+
+bcm2835-sdhost: Ignore CRC7 for MMC CMD1
+
+It seems that the sdhost interface returns CRC7 errors for CMD1,
+which is the MMC-specific SEND_OP_COND. Returning these errors to
+the MMC layer causes a downward spiral, but ignoring them seems
+to be harmless.
+
+bcm2835-mmc/sdhost: Remove ARCH_BCM2835 differences
+
+The bcm2835-mmc driver (and -sdhost driver that copied from it)
+contains code to handle SDIO interrupts in a threaded interrupt
+handler rather than waking the MMC framework thread. The change
+follows a patch from Russell King that adds the facility as the
+preferred way of working.
+
+However, the new code path is only present in ARCH_BCM2835
+builds, which I have taken to be a way of testing the waters
+rather than making the change across the board; I can't see
+any technical reason why it wouldn't be enabled for MACH_BCM270X
+builds. So this patch standardises on the ARCH_BCM2835 code,
+removing the old code paths.
+
+bcm2835-sdhost: Don't log timeout errors unless debug=1
+
+The MMC card-discovery process generates timeouts. This is
+expected behaviour, so reporting it to the user serves no purpose.
+Suppress the reporting of timeout errors unless the debug flag
+is on.
+
+bcm2835-sdhost: Add workaround for odd behaviour on some cards
+
+For reasons not understood, the sdhost driver fails when reading
+sectors very near the end of some SD cards. The problem could
+be related to the similar issue that reading the final sector
+of any card as part of a multiple read never completes, and the
+workaround is an extension of the mechanism introduced to solve
+that problem which ensures those sectors are always read singly.
+
+bcm2835-sdhost: Major revision
+
+This is a significant revision of the bcm2835-sdhost driver. It
+improves on the original in a number of ways:
+
+1) Through the use of CMD23 for reads it appears to avoid problems
+   reading some sectors on certain high speed cards.
+2) Better atomicity to prevent crashes.
+3) Higher performance.
+4) Activity logging included, for easier diagnosis in the event
+   of a problem.

+
+bcm2835-sdhost: Restore ATOMIC flag to PIO sg mapping
+
+Allocation problems have been seen in a wireless driver, and
+this is the only change which might have been responsible.
+
+SQUASH: bcm2835-sdhost: Only claim one DMA channel
+
+With both MMC controllers enabled there are few DMA channels left. The
+bcm2835-sdhost driver only uses DMA in one direction at a time, so it
+doesn't need to claim two channels.
+
+See: https://github.com/raspberrypi/linux/issues/1327

+
+bcm2835-sdhost: Workaround for "slow" sectors
+
+Some cards have been seen to cause timeouts after certain sectors are
+read. This workaround enforces a minimum delay between the stop after
+reading one of those sectors and a subsequent data command.
+
+Using CMD23 (SET_BLOCK_COUNT) avoids this problem, so good cards will
+not be penalised by this workaround.

+
+bcm2835-sdhost: Firmware manages the clock divisor
+
+The bcm2835-sdhost driver hands control of the CDIV clock divisor
+register to matching firmware, allowing it to adjust to a changing
+core clock. This removes the need to use the performance governor or
+to enable io_is_busy on the on-demand governor in order to get the
+best SD performance.
+
+N.B. As SD clocks must be an integer divisor of the core clock, it is
+possible that the SD clock for "turbo" mode can be different (even
+lower) than "normal" mode.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.org>
+
+bcm2835-sdhost: Reset the clock in task context
+
+Since reprogramming the clock can now involve a round-trip to the
+firmware it must not be done at atomic context, and a tasklet
+is not a task.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.org>
+
+bcm2835-sdhost: Don't exit cmd wait loop on error
+
+The FAIL flag can be set in the CMD register before command processing
+is complete, leading to spurious "failed to complete" errors. This has
+the effect of promoting harmless CRC7 errors during CMD1 processing
+into errors that can delay and even prevent booting.
+
+Also:
+1) Convert the last KERN_ERROR message in the register dumping to
+   KERN_INFO.
+2) Remove an unnecessary reset call from  bcm2835_sdhost_add_host.

+mmc: bcm2835-sdhost: Support underclocking
+
+Support underclocking of the SD bus in two ways:
+1. using the max-frequency DT property (which currently has no DT
+   parameter), and
+2. using the exiting sd_overclock parameter.
+
+The two methods differ slightly - in the former the MMC subsystem is
+aware of the underclocking, while in the latter it isn't - but the
+end results should be the same.

+mmc/bcm2835-sdhost: Recover from MMC_SEND_EXT_CSD
+
+If the user issues an "mmc extcsd read", the SD controller receives
+what it thinks is a SEND_IF_COND command with an unexpected data block.
+The resulting operations leave the FSM stuck in READWAIT, a state which
+persists until the MMC framework resets the controller, by which point
+the root filesystem is likely to have been unmounted.
+
+A less heavyweight solution is to detect the condition and nudge the
+FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
+
+N.B. This workaround was essentially discovered by accident and without
+a full understanding the inner workings of the controller, so it is
+fortunate that the "fix" only modifies error paths.
+
+See: https://github.com/raspberrypi/linux/issues/2728

+
+bcm2835-sdhost: Allow for sg entries that cross pages
+
+The dma_complete handling code calculates a virtual address for a page
+then adds an offset, but if the offset is more than a page and HIGHMEM
+is in use then the summed address could be in an unmapped (or just
+incorrect) page.
+
+The upstream SDHOST driver allows for this possibility - copy the code
+that does so.

+Subject: [PATCH] vc_mem: Add vc_mem driver for querying firmware memory
+ addresses
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Signed-off-by: popcornmix <popcornmix@gmail.com>
+
+BCM270x: Move vc_mem
+
+Make the vc_mem module available for ARCH_BCM2835 by moving it.
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+char: vc_mem: Fix up compat ioctls for 64bit kernel
+
+compat_ioctl wasn't defined, so 32bit user/64bit kernel
+always failed.
+VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size
+unsigned long, so the ioctl cmd changes between sizes.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vc_mem: Fix all coding style issues.
+
+Cleans up all checkpatch errors in vc_mem.c and vc_mem.h
+No functional change to the code.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vc_mem: Delete dead code
+
+There are no error exists once device_create has succeeded, and
+therefore no need to call device_destroy from vc_mem_init.

+bcm2835_smi: re-add dereference to fix DMA transfers
+
+bcm2835_smi_dev: Fix handling of word-odd lengths
+
+The read and write functions did not use the correct pointer offset
+when dealing with an odd number of bytes after a DMA transfer. Also,
+only handle the remaining odd bytes if the DMA transfer completed
+successfully.

+Subject: [PATCH] Add Chris Boot's i2c driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+i2c-bcm2708: fixed baudrate
+
+Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock).
+In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits.
+This resulted in incorrect setting of CDIV and higher baudrate than intended.
+Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz
+After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz
+The correct baudrate is shown in the log after the cdiv > 0xffff correction.
+
+Perform I2C combined transactions when possible
+
+Perform I2C combined transactions whenever possible, within the
+restrictions of the Broadcomm Serial Controller.
+
+Disable DONE interrupt during TA poll
+
+Prevent interrupt from being triggered if poll is missed and transfer
+starts and finishes.
+
+i2c: Make combined transactions optional and disabled by default
+
+i2c: bcm2708: add device tree support
+
+Add DT support to driver and add to .dtsi file.
+Setup pins in .dts file.
+i2c is disabled by default.

+
+bcm2708: don't register i2c controllers when using DT
+
+The devices for the i2c controllers are in the Device Tree.
+Only register devices when not using DT.
+
+Signed-off-by: Noralf Tronnes <notro@tronnes.org>
+
+I2C: Only register the I2C device for the current board revision
+
+i2c_bcm2708: Fix clock reference counting
+
+Fix grabbing lock from atomic context in i2c driver
+
+2 main changes:
+- check for timeouts in the bcm2708_bsc_setup function as indicated by this comment:
+      /* poll for transfer start bit (should only take 1-20 polls) */
+  This implies that the setup function can now fail so account for this everywhere it's called
+- Removed the clk_get_rate call from inside the setup function as it locks a mutex and that's not ok since we call it from under a spin lock.
+
+i2c-bcm2708: When using DT, leave the GPIO setup to pinctrl
+
+i2c-bcm2708: Increase timeouts to allow larger transfers
+
+Use the timeout value provided by the I2C_TIMEOUT ioctl when waiting
+for completion. The default timeout is 1 second.
+
+See: https://github.com/raspberrypi/linux/issues/260
+
+i2c-bcm2708/BCM270X_DT: Add support for I2C2
+
+The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
+use of this bus can break an attached display - use with caution.
+
+It is recommended to disable accesses by VideoCore by setting
+hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
+
+The interface is disabled by default - enable using the
+i2c2_iknowwhatimdoing DT parameter.
+
+bcm2708-spi: Don't use static pin configuration with DT
+
+Also remove superfluous error checking - the SPI framework ensures the
+validity of the chip_select value.
+
+i2c-bcm2708: Remove non-DT support
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.
+
+Fixes i2c_bcm2708: Write to FIFO correctly - v2 (#1574)
+
+* i2c: fix i2c_bcm2708: Clear FIFO before sending data
+
+Make sure FIFO gets cleared before trying to send
+data in case of a repeated start (COMBINED=Y).
+
+* i2c: fix i2c_bcm2708: Only write to FIFO when not full
+
+Check if FIFO can accept data before writing.
+To avoid a peripheral read on the last iteration of a loop,
+both bcm2708_bsc_fifo_fill and ~drain are changed as well.

+Subject: [PATCH] char: broadcom: Add vcio module
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add module for accessing the mailbox property channel through
+/dev/vcio. Was previously in bcm2708-vcio.
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+char: vcio: Add compat ioctl handling
+
+There was no compat ioctl handler, so 32 bit userspace on a
+64 bit kernel failed as IOCTL_MBOX_PROPERTY used the size
+of char*.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vcio: Fail probe if rpi_firmware is not found.
+
+Device Tree is now the only supported config mechanism, therefore
+uncomment the block of code that fails the probe if the
+firmware node can't be found.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+drivers: char: vcio: Use common compat header
+
+The definition of compat_ptr is now common for most platforms, but
+requires the inclusion of <linux/compat.h>.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+char: vcio: Rewrite as a firmware node child
+
+The old vcio driver is a simple character device that manually locates
+the firmware driver. Initialising it before the firmware driver causes
+a failure, and no retries are attempted.
+
+Rewrite vcio as a platform driver that depends on a DT node for its
+instantiation and the location of the firmware driver, making use of
+the miscdevice framework to reduce the code size.
+
+N.B. Using miscdevice changes the udev SUBSYSTEM string, so a change
+to the companion udev rule is required in order to continue to set
+the correct device permissions, e.g.:
+
+    KERNEL="vcio", GROUP="video", MODE="0660"
+
+See: https://github.com/raspberrypi/linux/issues/4620

+Subject: [PATCH] leds: Add the "input" trigger, for pwr_led
+
+The "input" trigger makes the associated GPIO an input.  This is to support
+the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
+
+N.B. pwr_led is not available on Model A or B boards.
+
+leds-gpio: Implement the brightness_get method
+
+The power LED uses some clever logic that means it is driven
+by a voltage measuring circuit when configured as input, otherwise
+it is driven by the GPIO output value. This patch wires up the
+brightness_get method for leds-gpio so that user-space can monitor
+the LED value via /sys/class/gpio/led1/brightness. Using the input
+trigger this returns an indication of the system power health,
+otherwise it is just whatever value the trigger has written most
+recently.
+
+See: https://github.com/raspberrypi/linux/issues/1064

+Subject: [PATCH] Improve __copy_to_user and __copy_from_user performance
+
+Provide a __copy_from_user that uses memcpy. On BCM2708, use
+optimised memcpy/memmove/memcmp/memset implementations.
+
+arch/arm: Add mmiocpy/set aliases for memcpy/set
+
+See: https://github.com/raspberrypi/linux/issues/1082
+
+copy_from_user: CPU_SW_DOMAIN_PAN compatibility
+
+The downstream copy_from_user acceleration must also play nice with
+CONFIG_CPU_SW_DOMAIN_PAN.

+
+Fix copy_from_user if BCM2835_FAST_MEMCPY=n
+
+The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
+changed the behaviour of arm_copy_from_user. The page pinning code
+is not safe on ARMv7 if LPAE & high memory is enabled and causes
+crashes which look like PTE corruption.
+
+Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
+which is really an ARMv6 / Pi1 optimization and not necessary on newer
+ARM processors.
+
+arm: fix mmap unlocks in uaccess_with_memcpy.c
+
+This is a regression that was added with the commit 192a4e923ef092924dd013e7326f2ec520ee4783 as of rpi-5.8.y, since that is when the move to the mmap locking API was introduced - d8ed45c5dcd455fc5848d47f86883a1b872ac0d0
+
+The issue is that when the patch to improve performance for the __copy_to_user and __copy_from_user functions were added for the Raspberry Pi, some of the mmaps were incorrectly mapped to write instead of read. This would cause a verity of issues, and in my case, prevent the booting of a squashfs filesystem on rpi-5.8-y and above. An example of the panic you would see from this can be seen at https://pastebin.com/raw/jBz5xCzL

+arch/arm: Add __memset alias to memset_rpi.S
+
+memset_rpi.S is an optimised memset implementation, but doesn't define
+__memset (which was just added to memset.S). As a result, building
+for the BCM2835 platform causes a link failure.
+
+Add __memset as yet another alias to our common implementation.

+Subject: [PATCH] gpio-poweroff: Allow it to work on Raspberry Pi
+
+The Raspberry Pi firmware manages the power-down and reboot
+process. To do this it installs a pm_power_off handler, causing
+the gpio-poweroff module to abort the probe function.
+
+This patch introduces a "force" DT property that overrides that
+behaviour, and also adds a DT overlay to enable and control it.
+
+Note that running in an active-low configuration (DT parameter
+"active_low") requires a custom dt-blob.bin and probably won't
+allow a reboot without switching off, so an external inversion
+of the trigger signal may be preferable.

+Subject: [PATCH] bcm2835-virtgpio: Virtual GPIO driver
+
+Add a virtual GPIO driver that uses the firmware mailbox interface to
+request that the VPU toggles LEDs.
+
+gpio: bcm-virt: Fix the get() method
+
+The get() method does not understand the on-the-wire encoding of the
+remote GPIO states, thinking they are simple on/off bits when they are
+really pairs of 16-bit counts. Rewrite the get() handler to return the
+value last written, which will eventually match the actual GPIO state
+if there are no other changes.
+
+See: https://github.com/raspberrypi/linux/issues/4638

+Subject: [PATCH] OF: DT-Overlay configfs interface
+
+This is a port of Pantelis Antoniou's v3 port that makes use of the
+new upstreamed configfs support for binary attributes.
+
+Original commit message:
+
+Add a runtime interface to using configfs for generic device tree overlay
+usage. With it its possible to use device tree overlays without having
+to use a per-platform overlay manager.
+
+Please see Documentation/devicetree/configfs-overlays.txt for more info.
+
+Changes since v2:
+- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
+- Created a documentation entry
+- Slight rewording in Kconfig
+
+Changes since v1:
+- of_resolve() -> of_resolve_phandles().

+
+There is an error when compiling rpi-4.6.y branch:

+drivers/of/configfs.c:291:21: note: (near initialization for 'of_cfs_subsys.su_group.default_groups.next')
+
+The .default_groups is linked list since commit

+of: configfs: Use of_overlay_fdt_apply API call
+
+The published API to the dynamic overlay application mechanism now
+takes a Flattened Device Tree blob as input so that it can manage the
+lifetime of the unflattened tree. Conveniently, the new API call -
+of_overlay_fdt_apply - is virtually a drop-in replacement for
+create_overlay, which can now be deleted.

++Howto use the configfs overlay interface.
++
++A device-tree configfs entry is created in /config/device-tree/overlays
++and and it is manipulated using standard file system I/O.
++Note that this is a debug level interface, for use by developers and
++not necessarily something accessed by normal users due to the
++security implications of having direct access to the kernel's device tree.
++
++* To create an overlay you mkdir the directory:
++
++	# mkdir /config/device-tree/overlays/foo
++
++* Either you echo the overlay firmware file to the path property file.
++
++	# echo foo.dtbo >/config/device-tree/overlays/foo/path
++
++* Or you cat the contents of the overlay to the dtbo file
++
++	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
++
++The overlay file will be applied, and devices will be created/destroyed
++as required.
++
++To remove it simply rmdir the directory.
++
++	# rmdir /config/device-tree/overlays/foo
++
++The rationalle of the dual interface (firmware & direct copy) is that each is
++better suited to different use patterns. The firmware interface is what's
++intended to be used by hardware managers in the kernel, while the copy interface
++make sense for developers (since it avoids problems with namespaces).

+Revert "brcmfmac: Disable power management"
+
+Shortly after the release of the Pi 3B, a loss of SSH connectivity
+over WiFi was traced to the power management handling, so power
+management was disabled. And so it has remained ever since.
+
+Enabling power management saves 55mA (~270mW) on a Pi 4B, so is very
+much worth the minimal effort of reverting this patch, which was
+squashed and rebased many times since then to the commit hash is
+meaningless.

+Subject: [PATCH] hci_h5: Don't send conf_req when ACTIVE
+
+Without this patch, a modem and kernel can continuously bombard each
+other with conf_req and conf_rsp messages, in a demented game of tag.

+Subject: [PATCH] ARM64: Round-Robin dispatch IRQs between CPUs.
+
+IRQ-CPU mapping is round robined on ARM64 to increase
+concurrency and allow multiple interrupts to be serviced
+at a time.  This reduces the need for FIQ.

+Mainline status:
+
+There is a commit in linux-next that standardize passing the serial
+number through Device Tree (string: /serial-number):
+ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
+
+There was an attempt to do the same with the revision number, but it

+Subject: [PATCH] dwc-otg: FIQ: Fix "bad mode in data abort handler"
+
+Create a semi-static mapping for the USB registers early in the boot
+process, before additional kernel threads are started, so all threads
+will have the mappings from the start. This avoids the need for
+data aborts to lazily update them.

+Subject: [PATCH] i2c-gpio: Also set bus numbers from reg property
+
+I2C busses can be assigned specific bus numbers using aliases in
+Device Tree - string properties where the name is the alias and the
+value is the path to the node. The current DT parameter mechanism
+does not allow property names to be derived from a parameter value
+in any way, so it isn't possible to generate unique or matching
+aliases for nodes from an overlay that can generate multiple
+instances, e.g. i2c-gpio.
+
+Work around this limitation (at least temporarily) by allowing
+the i2c adapter number to be initialised from the "reg" property
+if present.

++Driver a GPIO line that can be used to turn the power off.
++
++The driver supports both level triggered and edge triggered power off.
++At driver load time, the driver will request the given gpio line and
++install a handler to power off the system. If the optional properties
++'input' is not found, the GPIO line will be driven in the inactive
++state. Otherwise its configured as an input.
++
++When the power-off handler is called, the gpio is configured as an
++output, and drive active, so triggering a level triggered power off
++condition. This will also cause an inactive->active edge condition, so
++triggering positive edge triggered power off. After a delay of 100ms,
++the GPIO is set to inactive, thus causing an active->inactive edge,
++triggering negative edge triggered power off. After another 100ms
++delay the GPIO is driver active again. If the power is still on and
++the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
++
++Required properties:
++- compatible : should be "gpio-poweroff".
++- gpios : The GPIO to set high/low, see "gpios property" in
++  Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
++  low to power down the board set it to "Active Low", otherwise set
++  gpio to "Active High".
++
++Optional properties:
++- input : Initially configure the GPIO line as an input. Only reconfigure
++  it to an output when the power-off handler is called. If this optional
++  property is not specified, the GPIO is initialized as an output in its
++  inactive state.
++- active-delay-ms: Delay (default 100) to wait after driving gpio active
++- inactive-delay-ms: Delay (default 100) to wait after driving gpio inactive
++- timeout-ms: Time to wait before asserting a WARN_ON(1). If nothing is
++              specified, 3000 ms is used.
++- export : Export the GPIO line to the sysfs system
++
++Examples:
++
++gpio-poweroff {
++	compatible = "gpio-poweroff";
++	gpios = <&gpio 4 0>;
++	timeout-ms = <3000>;

+Subject: [PATCH] irqchip: irq-bcm2835: Calc. FIQ_START at boot-time
+
+ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
+changed the way that the BCM2836/7 local interrupts are mapped; instead
+of being pre-mapped they are now mapped on-demand. A side effect of this
+change is that the call to irq_of_parse_and_map from armctrl_of_init
+creates a new mapping, forming a gap between the IRQs and the FIQs. This
+ gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
+
+1) that the value of FIQ_START is the same as the number of normal IRQs
+that will be mapped (still true), and
+
+2) that this value is also the offset between an IRQ and its equivalent
+FIQ (which is no longer the case).
+
+Remove both assumptions by measuring the interval between the last IRQ
+and the last FIQ, passing it as the parameter to init_FIQ().

+Subject: [PATCH] net: lan78xx: Disable TCP Segmentation Offload (TSO)
+
+TSO seems to be having issues when packets are dropped and the
+remote end uses Selective Acknowledge (SACK) to denote that
+data is missing. The missing data is never resent, so the
+connection eventually stalls.
+
+There is a module parameter of enable_tso added to allow
+further debugging without forcing a rebuild of the kernel.

+
+As of 4.18, a firmware that implements the update_connect_params

+disabled firmware roaming in 4.4 [1] because it appeared to
+prevent disconnects, but let's try with the current firmware to see
+if things have improved.

+Avoid a hard userspace ABI change by adding a compatible get_throttled

+Subject: [PATCH] drivers: thermal: step_wise: add support for hysteresis
+
+Step wise governor increases the mitigation level when the temperature
+goes above a threshold and will decrease the mitigation when the
+temperature falls below the threshold. If it were a case, where the
+temperature hovers around a threshold, the mitigation will be applied
+and removed at every iteration. This reaction to the temperature is
+inefficient for performance.
+
+The use of hysteresis temperature could avoid this ping-pong of
+mitigation by relaxing the mitigation to happen only when the
+temperature goes below this lower hysteresis value.

+
+Ethernet cables with faulty or missing pairs (specifically pairs C and
+D) allow auto-negotiation to 1000Mbs, but do not support the successful
+establishment of a link. Add a DT property, "microchip,downshift-after",
+to configure the number of auto-negotiation failures after which it
+falls back to 100Mbs. Valid values are 2, 3, 4, 5 and 0, where 0 means
+never downshift.

+Subject: [PATCH] lan78xx: Debounce link events to minimize poll storm
+
+The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
+that the driver pays attention to is "link was reset". If there's a
+flapping status bit in that endpoint data, (such as if PHY negotiation
+needs a few tries to get a stable link) then polling at a slower rate
+would act as a de-bounce.
+

+
+Add the ability to interpret the high bits of the dreq specifier as
+flags to be included in the DMA_CS register. The motivation for this
+change is the ability to set the DISDEBUG flag for SD card transfers
+to avoid corruption when using the VPU debugger.

+374 is required for 1080P24-30 UYVY over 2 lanes @ 972Mbit/s, but

+Subject: [PATCH] media: tc358743: Check I2C succeeded during probe.
+
+The probe for the TC358743 reads the CHIPID register from
+the device and compares it to the expected value of 0.
+If the I2C request fails then that also returns 0, so
+the driver loads thinking that the device is there.
+
+Generally I2C communications are reliable so there is
+limited need to check the return value on every transfer,
+therefore only amend the one read during probe to check
+for I2C errors.

++Broadcom BCM283x Camera Interface (Unicam)
++------------------------------------------
++
++The Unicam block on BCM283x SoCs is the receiver for either
++CSI-2 or CCP2 data from image sensors or similar devices.
++
++The main platform using this SoC is the Raspberry Pi family of boards.
++On the Pi the VideoCore firmware can also control this hardware block,
++and driving it from two different processors will cause issues.
++To avoid this, the firmware checks the device tree configuration
++during boot. If it finds device tree nodes called csi0 or csi1 then
++it will stop the firmware accessing the block, and it can then
++safely be used via the device tree binding.
++
++Required properties:
++===================
++- compatible	: must be "brcm,bcm2835-unicam".
++- reg		: physical base address and length of the register sets for the
++		  device.
++- interrupts	: should contain the IRQ line for this Unicam instance.
++- clocks	: list of clock specifiers, corresponding to entries in
++		  clock-names property.
++- clock-names	: must contain an "lp" entry, matching entries in the
++		  clocks property.
++
++Unicam supports a single port node. It should contain one 'port' child node
++with child 'endpoint' node. Please refer to the bindings defined in
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Within the endpoint node the "remote-endpoint" and "data-lanes" properties
++are mandatory.
++Data lane reordering is not supported so the data lanes must be in order,
++starting at 1. The number of data lanes should represent the number of
++usable lanes for the hardware block. That may be limited by either the SoC or
++how the platform presents the interface, and the lower value must be used.
++
++Lane reordering is not supported on the clock lane either, so the optional
++property "clock-lane" will implicitly be <0>.
++Similarly lane inversion is not supported, therefore "lane-polarities" will
++implicitly be <0 0 0 0 0>.
++Neither of these values will be checked.
++
++Example:
++	csi1: csi1@7e801000 {
++		compatible = "brcm,bcm2835-unicam";
++		reg = <0x7e801000 0x800>,
++		      <0x7e802004 0x4>;
++		interrupts = <2 7>;
++		clocks = <&clocks BCM2835_CLOCK_CAM1>;
++		clock-names = "lp";
++
++		port {
++			csi1_ep: endpoint {
++				remote-endpoint = <&tc358743_0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};
++
++	i2c0: i2c@7e205000 {
++		tc358743: csi-hdmi-bridge@0f {
++			compatible = "toshiba,tc358743";
++			reg = <0x0f>;
++
++			clocks = <&tc358743_clk>;
++			clock-names = "refclk";
++
++			tc358743_clk: bridge-clk {
++				compatible = "fixed-clock";
++				#clock-cells = <0>;
++				clock-frequency = <27000000>;
++			};
++
++			port {
++				tc358743_0: endpoint {
++					remote-endpoint = <&csi1_ep>;
++					clock-lanes = <0>;
++					data-lanes = <1 2>;
++					clock-noncontinuous;
++					link-frequencies =
++						/bits/ 64 <297000000>;
++				};
++			};
++		};
++	};

+Subject: [PATCH] media: tc358743: Return an appropriate colorspace from
+ tc358743_set_fmt
+
+When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
+to choose a valid format. However that sets the colorspace
+based on what was read back from the chip. When you set the format,
+then the driver would choose and program the colorspace based
+on the format code.
+
+The result was that if you called try or set format for UYVY
+when the current format was RGB3 then you would get told sRGB,
+and try RGB3 when current was UYVY and you would get told
+SMPTE170M.
+
+The value programmed into the chip is determined by this driver,
+therefore there is no need to read back the value. Return the
+colorspace based on the format set/tried instead.

+Split the current implementation into two, one step which

+Subject: [PATCH] staging: mmal-vchiq: Fix client_component for 64 bit kernel
+
+The MMAL client_component field is used with the event
+mechanism to allow the client to identify the component for
+which the event is generated.
+The field is only 32bits in size, therefore we can't use a
+pointer to the component in a 64 bit kernel.
+
+Component handles are already held in an array per VCHI
+instance, so use the array index as the client_component handle
+to avoid having to create a new IDR for this purpose.

+
+The ioremapping creates mappings within the vmalloc area. The
+equivalent early function, create_mapping, now checks that the
+requested explicit virtual address is between VMALLOC_START and
+VMALLOC_END. As there is no reason to have any correlation between
+the physical and virtual addresses, put the required mappings at
+VMALLOC_START and above.

+Subject: [PATCH] net: genet: enable link energy detect powerdown for external
+ PHYs
+
+There are several warts surrounding bcmgenet_mii_probe() as this
+function is called from ndo_open, but it's calling registration-type
+functions. The probe should be called at probe time and refactored
+such that the PHY device data can be extracted to limit the scope
+of this flag to Broadcom PHYs.
+
+For now, pass this flag in as it puts our attached PHY into a low-power
+state when disconnected.

+Subject: [PATCH] usb: add plumbing for updating interrupt endpoint interval
+ state
+
+xHCI caches device and endpoint data after the interface is configured,
+so an explicit command needs to be issued for any device driver wanting
+to alter the polling interval of an endpoint.
+
+Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
+called after calculating endpoint bandwidth requirements but before any
+URBs are submitted.
+
+If polling intervals are shortened, any bandwidth reservations are no
+longer valid but in practice polling intervals are only ever relaxed.
+
+Limit the scope to interrupt transfers for now.

+Subject: [PATCH] i2c: bcm2835: Set clock-stretch timeout to 35ms
+
+The BCM2835 I2C blocks have a register to set the clock-stretch
+timeout - how long the device is allowed to hold SCL low - in bus
+cycles. The current driver doesn't write to the register, therefore
+the default value of 64 cycles is being used for all devices.
+
+Set the timeout to the value recommended for SMBus - 35ms.

+Subject: [PATCH] hid: usb: Add device quirks for Freeway Airmouse T3 and MX3
+
+These wireless mouse/keyboard combo remote control devices specify
+multiple "wheel" events in their report descriptors. The wheel events
+are incorrectly defined and apparently map to accelerometer data, leading
+to spurious mouse scroll events being generated at an extreme rate when
+the device is moved.
+
+As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask
+feeding the extra wheel events to the input subsystem.

+Subject: [PATCH] net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
+
+Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
+DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
+address. In the failure case, the Pi is left able to receive packets
+but not send them, suggesting that the MAC<->PHY link is getting into
+a bad state.
+
+It has been found empirically that skipping a reset step by the genet
+driver prevents the failures. No downsides have been discovered yet,
+and unlike the forced renegotiation it doesn't increase the time to
+get an IP address, so the workaround is enabled by default; add
+
+  genet.skip_umac_reset=n
+
+to the command line to disable it.

+Subject: [PATCH] xhci: Use more event ring segment table entries
+
+Users have reported log spam created by "Event Ring Full" xHC event
+TRBs. These are caused by interrupt latency in conjunction with a very
+busy set of devices on the bus. The errors are benign, but throughput
+will suffer as the xHC will pause processing of transfers until the
+event ring is drained by the kernel. Expand the number of event TRB slots
+available by increasing the number of event ring segments in the ERST.
+
+Controllers have a hardware-defined limit as to the number of ERST
+entries they can process, so make the actual number in use
+min(ERST_MAX_SEGS, hw_max).

+media: i2c: imx258: Make image geometry meet sensor requirements
+
+The output image is defined as being 4208x3118 pixels in size.
+Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
+3119 lines total.
+
+The datasheet lists a requirement for Y_ADD_STA to be a multiple
+of a power of 2 depending on binning/scaling mode (2 for full pixel,
+4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
+for (x4-bin)+(x2-subsample)).
+(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
+
+The current configuration for the full res modes breaks that second
+requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
+the same field of view as that then breaks the first requirement.
+For the binned modes, they are worse off as 3118 is not a multiple of
+4.
+
+Increase the main mode to 4208x3120 so that it is the same FOV as the
+binned modes, with Y_ADD_STA at 0.
+Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
+sensor requirements.
+
+This does change the Bayer order as the default configuration is for
+H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
+and this patch has changed Y_STA_END.

+media: i2c: imx258: Disable digital cropping on binned modes
+
+The binned modes set DIG_CROP_X_OFFSET and DIG_CROP_IMAGE_WIDTH
+to less than the full image, even though the image being captured
+is meant to be a scaled version of the full array size.
+
+Reduce X_OFFSET to 0, and increase IMAGE_WIDTH to the full array.

+media: i2c: imx258: Implement HFLIP and VFLIP controls.
+
+The sensor supports H & V flips, so implement the relevant controls.
+Note that the Bayer order changes with these flips, therefore
+they set the V4L2_CTRL_FLAG_MODIFY_LAYOUT property.
+
+As we now support flips, remove the restriction of the sensor only

+Subject: [PATCH] media: i2c: imx290: Support for the Sony IMX290 sensor
+
+media: i2c: imx290: set the format before VIDIOC_SUBDEV_G_FMT is called
+
+Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
+
+With the current driver 'media-ctl -p' issued right after the imx290 driver
+is loaded prints:
+pad0: Source
+             [fmt:unknown/0x0]
+
+The format value of zero is due to the current_format field of the imx290
+struct not being initialized yet.
+
+As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
+is also initialized, so the line which set current_mode to a default value
+in driver's probe() function is no longer needed.

+added support for running in two lane mode (instead of 4), but
+without changing the link frequency that resulted in a max of 30fps.
+
+Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
+and pixel rate" then doubled the link frequency when in 2 lane mode,
+but didn't undo the correction for running at only 30fps, just extending
+horizontal blanking instead.
+It also didn't update the CSI timing registers in accordance with the
+datasheet.
+
+Remove the 30fps limit on 2 lane by correcting the register config
+in accordance with the datasheet for 60fps operation over 2 lanes.
+Frame rate control (via V4L2_CID_VBLANK or HBLANK) can still reduce

+media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s

+Whilst the datasheet lists the link frequency changing between

+we have
+(1920 + 280) * (1080 + 45) * 60fps = 148.5MPix/s
+and
+(1280 + 2020) * (720 + 30) * 60fps = 148.5MPix/s
+and this reflects reality whether in 10 or 12 bit readout modes.
+
+How this relates to link frequency is unclear as it differs
+from the datasheet, but all exposure and frame rate calcs need

+potentially also changed.
+
+VBLANK is no longer reset, and even if it is, then the set_ctrl

++description: |-
++  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
++  sensor with square pixel array and 1.58 M effective pixels. This chip
++  features a global shutter with variable charge-integration time. It is
++  programmable through I2C and 4-wire interfaces. The sensor output is
++  available via CSI-2 serial data output (1 Lane).

+media: i2c: imx477: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the imx477 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (8, 16) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.
+
+This commit mirrors 543790f777ba1b3264c168c653db6d415e7c983f done for
+the imx219 sensor.

+The V4L2_CID_EXPOSURE_AUTO_PRIORITY was used to let the sensor control

+
+Add support for very long exposures by using the exposure multiplier
+register. Userland does not need to pass any additional controls to
+enable long exposures, it simply requests a larger vblank to extend the
+exposure control range appropriately.
+
+Currently, since hblank is fixed, a maximum of approximately 124 seconds
+of exposure time can be used. In a future change, hblank could also be
+controlled in userland to give over 200 seconds of exposure time.

+media: i2c: imx477: Reset hblank on mode switch
+
+Reset the hblank control to the minimum value on every mode switch. This is to
+account for userland instances that do not yet control hblank, otherwise it
+gets set to a non-optimal value.

+
+media: i2c: imx477: Do not unconditionally adjust hblank and vblank limits
+
+On a mode change, only call imx477_set_framing_limits() to adjust the hblank
+and vblank limits if the new mode is different from the existing mode. This
+preserves any manual control values the user might have set.

++description: |-
++  The Sony IMX477 is a 1/2.3-inch CMOS active pixel digital image sensor
++  with an active array size of 4056H x 3040V. It is programmable through
++  I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
++  Image data is sent through MIPI CSI-2, which is configured as either 2 or
++  4 data lanes.

++* Infineon irs1125 time of flight sensor
++
++The Infineon irs1125 is a time of flight digital image sensor with
++an active array size of 352H x 286V. It is programmable through I2C
++interface. The I2C address defaults to 0x3D, but can be reconfigured
++to address 0x3C or 0x41 via I2C commands. Image data is sent through
++MIPI CSI-2, which is configured as either 1 or 2 data lanes.
++
++Required Properties:
++- compatible: value should be "infineon,irs1125" for irs1125 sensor
++- reg: I2C bus address of the device
++- clocks: reference to the xclk input clock.
++- pwdn-gpios: reference to the GPIO connected to the reset pin.
++	      This is an active low signal to the iirs1125.
++
++The irs1125 device node should contain one 'port' child node with
++an 'endpoint' subnode. For further reading on port node refer to
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Endpoint node required properties for CSI-2 connection are:
++- remote-endpoint: a phandle to the bus receiver's endpoint node.
++- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
++- data-lanes: should be set to <1> or <1 2> (one or two lane CSI-2
++  supported)
++
++Example:
++	sensor@10 {
++		compatible = "infineon,irs1125";
++		reg = <0x3D>;
++		#address-cells = <1>;
++		#size-cells = <0>;
++		clocks = <&irs1125_clk>;
++		pwdn-gpios = <&gpio 5 0>;
++
++		irs1125_clk: camera-clk {
++			compatible = "fixed-clock";
++			#clock-cells = <0>;
++			clock-frequency = <26000000>;
++		};
++
++		port {
++			sensor_out: endpoint {
++				remote-endpoint = <&csiss_in>;
++				clock-lanes = <0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};

+Subject: [PATCH] Initialise rpi-firmware before clk-bcm2835
+
+The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
+Platform Module) having been registered when it initialises; otherwise
+it assumes there is no TPM. It has been observed on BCM2835 that IMA
+is initialised before TPM, and that initialising the BCM2835 clock
+driver before the firmware driver has the effect of reversing this
+order.
+
+Change the firmware driver to initialise at core_initcall, delaying the
+BCM2835 clock driver to postcore_initcall.
+
+See: https://github.com/raspberrypi/linux/issues/3291

+Subject: [PATCH] of: overlay: Correct symbol path fixups
+
+When symbols from overlays are added to the live tree their paths must
+be rebased. The translated symbol is normally the result of joining
+the fragment-relative path (with a leading "/") to the target path
+(either copied directly from the "target-path" property or resolved
+from the phandle). This translation fails when the target is the root
+node (a common case for Raspberry Pi overlays) because the resulting
+path starts with a double slash. For example, if target-path is "/" and
+the fragment adds a node called "newnode", the label associated with
+that node will be assigned the path "//newnode", which can't be found
+in the tree.
+
+Fix the failure case by explicitly replacing a target path of "/" with
+an empty string.

++Brcmstb PCIe Host Controller Device Tree Bindings
++
++Required Properties:
++- compatible
++  "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
++  "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.

++  "brcm,bcm7278-pcie"  -- for 7278 family ARM-based SOCs.
++
++- reg -- the register start address and length for the PCIe reg block.
++- interrupts -- two interrupts are specified; the first interrupt is for
++     the PCI host controller and the second is for MSI if the built-in
++     MSI controller is to be used.
++- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
++- #address-cells -- set to <3>.
++- #size-cells -- set to <2>.
++- #interrupt-cells: set to <1>.
++- interrupt-map-mask and interrupt-map, standard PCI properties to define the

++- ranges: ranges for the PCI memory and I/O regions.
++- linux,pci-domain -- should be unique per host controller.
++
++Optional Properties:
++- clocks -- phandle of pcie clock.
++- clock-names -- set to "sw_pcie" if clocks is used.
++- dma-ranges -- Specifies the inbound memory mapping regions when

++V4L2_PIX_FMT_NV21_COL128
++Formats with ½ horizontal and vertical chroma resolution. This format
++has two planes - one for luminance and one for chrominance. Chroma
++samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
++memory layout. The image is split into columns of 128 bytes wide rather than
++being in raster order.
++
++V4L2_PIX_FMT_NV12_10_COL128
++Follows the same pattern as ``V4L2_PIX_FMT_NV21_COL128`` with 128 byte, but is
++a 10bit format with 3 10-bit samples being packed into 4 bytes. Each 128 byte
++wide column therefore contains 96 samples.
++
++
++Description
++===========
++
++This is the two-plane versions of the YUV 4:2:0 format where data is
++grouped into 128 byte wide columns. The three components are separated into
++two sub-images or planes. The Y plane has one byte per pixel and pixels
++are grouped into 128 byte wide columns. The CbCr plane has the same width,
++in bytes, as the Y plane (and the image), but is half as tall in pixels.
++The chroma plane is also in 128 byte columns, reflecting 64 Cb and 64 Cr
++samples.
++
++The chroma samples for a column follow the luma samples. If there is any
++paddding, then that will be reflected via the selection API.
++The luma height must be a multiple of 2 lines.
++
++The normal bytesperline is effectively fixed at 128. However the format
++requires knowledge of the stride between columns, therefore the bytesperline
++value has been repurposed to denote the number of 128 byte long lines between
++the start of each column.
++
++**Byte Order.**

++V4L2_PIX_FMT_NV12_10_COL128 uses the same 128 byte column structure, but
++encodes 10-bit YUV.
++3 10-bit values are packed into 4 bytes as bits 9:0, 19:10, and 29:20, with
++bits 30 & 31 unused. For the luma plane, bits 9:0 are Y0, 19:10 are Y1, and
++29:20 are Y2. For the chroma plane the samples always come in pairs of Cr
++and Cb, so it needs to be considered 6 values packed in 8 bytes.

+Subject: [PATCH] RFC: media: Add media_request_{pin,unpin} API
+
+This is probably not the API we will want to add, but it
+should show what semantics are needed by drivers.
+
+The goal is to allow the OUTPUT (aka source) buffer and the
+controls associated to a request to be released from the request,
+and in particular return the OUTPUT buffer back to userspace,
+without signalling the media request fd.
+
+This is useful for devices that are able to pre-process
+the OUTPUT buffer, therefore able to release it before
+the decoding is finished. These drivers should signal
+the media request fd only after the CAPTURE buffer is done.

+Subject: [PATCH] staging: media: rpivid: Add Raspberry Pi V4L2 H265 decoder
+
+This driver is for the HEVC/H265 decoder block on the Raspberry
+Pi 4, and conforms to the V4L2 stateless decoder API.
+
+Signed-off-by: John Cox <jc@kynesim.co.uk>
+
+staging: media: rpivid: Select MEDIA_CONTROLLER and MEDIA_CONTROLLER_REQUEST_API
+
+MEDIA_CONTROLLER_REQUEST_API is a hidden option. If rpivid depends on it,
+the user would need to first enable another driver that selects
+MEDIA_CONTROLLER_REQUEST_API, and only then rpivid would become available.
+
+By selecting it instead of depending on it, it becomes possible to enable
+rpivid without having to enable other potentially unnecessary drivers.

+media: rpivid: Remove the need to have num_entry_points set
+
+VAAPI H265 has num entry points but never sets it. Allow a VAAPI
+shim to work without requiring rewriting the VAAPI driver.
+num_entry_points can be calculated from the slice_segment_addr
+of the next slice so delay processing until we have that.
+
+Also includes some minor cosmetics.

+
+media: rpivid: Convert to MPLANE
+
+Use multi-planar interface rather than single plane interface. This
+allows dmabufs holding compressed data to be resized.

+
+media: rpivid: Add an enable count to irq claim Qs
+
+Add an enable count to the irq Q structures to allow the irq logic to
+block further callbacks if resources associated with the irq are not
+yet available.
+
+Signed-off-by: John Cox <jc@kynesim.co.uk>
+
+media: rpivid: Add a Pass0 to accumulate slices and rework job finish
+
+Due to overheads in assembling controls and requests it is worth having
+the slice assembly phase separate from the h/w pass1 processing. Create
+a queue to service pass1 rather than have the pass1 finished callback
+trigger the next slice job.
+
+This requires a rework of the logic that splits up the buffer and
+request done events. This code contains two ways of doing that, we use
+Ezequiel Garcias <ezequiel@collabora.com> solution, but expect that
+in the future this will be handled by the framework in a cleaner manner.
+
+Fix up the handling of some of the memory exhaustion crashes uncovered
+in the process of writing this code.

+
+media: rpivid: Fix H265 aux ent reuse of the same slot
+
+It is legitimate, though unusual, for an aux ent associated with a slot
+to be selected in phase 0 before a previous selection has been used and
+released in phase 2. Fix such that if the slot is found to be in use
+that the aux ent associated with it is reused rather than an new aux
+ent being created. This fixes a problem where when the first aux ent
+was released the second was lost track of.
+
+This bug spotted in Nick's testing. It may explain some other occasional,
+unreliable decode error reports where dmesg included "Missing DPB AUX
+ent" logging.

+
+media: rpivid: Update to compile with new hevc decode params

+
+media: rpivid: Make slice ctrl dynamic
+
+Allows the user to submit a whole frames worth of slice headers in
+one lump along with a single bitstream dmabuf for the whole lot.
+This saves potentially a lot of bitstream copying.

+
+media: rpivid: Only create aux entries for H265 if needed
+
+Only create aux entries of mv info for frames where that info might

+
+media: rpivid: Avoid returning EINVAL to a G_FMT ioctl
+
+V4L2 spec says that G/S/TRY_FMT IOCTLs should never return errors for
+anything other than wrong buffer types. Improve the capture format
+function such that this is so and unsupported values get converted
+to supported ones properly.

+
+media: rpivid: Ensure IRQs have completed before uniniting context
+
+Before uniniting the decode context sync with the IRQ queues to ensure
+that decode no longer has any buffers in use.  This fixes a problem that
+manifested as ffmpeg leaking CMA buffers when it did a stream off on
+OUTPUT before CAPTURE, though in reality it was probably much more
+dangerous than that.

+rpivid: Use clk_get_max_rate()

+Allow the START_CODE control to take ANNEX_B as a value. This makes no

+Subject: [PATCH] spi: Force CS_HIGH if GPIO descriptors are used
+
+Commit f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
+amended of_spi_parse_dt() to always set SPI_CS_HIGH for SPI slaves whose
+Chip Select is defined by a "cs-gpios" devicetree property.
+
+This change breaks drivers whose probe functions set the mode field of
+the spi_device because in doing so they clear the SPI_CS_HIGH flag.
+
+Fix by setting SPI_CS_HIGH in spi_setup (under the same conditions as
+in of_spi_parse_dt()).
+
+See also: 83b2a8fe43bd ("spi: spidev: Fix CS polarity if GPIO descriptors are used")
+
+Fixes: f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+SQUASH: spi: Demote SPI_CS_HIGH warning to KERN_DEBUG
+
+This warning is unavoidable from a client's perspective and
+doesn't indicate anything wrong (just surprising).
+
+SQUASH with "spi: use_gpio_descriptor fixup moved to spi_setup"

++Sensor Ancillary Metadata
++
++Description
++===========
++
++This format describes ancillary data generated by a camera sensor and
++transmitted over a stream on the camera bus. Sensor vendors generally have their
++own custom format for this ancillary data. Some vendors follow a generic
++CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
++<https://mipi.org/specifications/csi-2>`_
++
++The size of the embedded buffer is defined as a single line with a pixel width
++width specified in bytes. This is obtained by a call to the
++:c:type:`VIDIOC_SUBDEV_G_FMT` ioctl on the sensor subdevice where the ``pad``
++field in :c:type:`v4l2_subdev_format` is set to 1.  Note that this size is fixed
++and cannot be modified with a call to :c:type:`VIDIOC_SUBDEV_S_FMT`.

++BCM2835 ISP Driver
++==================
++
++Introduction
++------------
++
++The BCM2835 Image Sensor Pipeline (ISP) is a fixed function hardware pipeline
++for performing image processing operations.  Images are fed to the input
++of the ISP through memory frame buffers.  These images may be in various YUV,
++RGB, or Bayer formats.  A typical use case would have Bayer images obtained from
++an image sensor by the BCM2835 Unicam peripheral, written to a memory
++frame buffer, and finally fed into the input of the ISP.  Two concurrent output
++images may be generated in YUV or RGB format at different resolutions.
++Statistics output is also generated for Bayer input images.
++
++The bcm2835-isp driver exposes the following media pads as V4L2 device nodes:
++
++.. tabularcolumns:: |l|l|l|l|

++.. cssclass: longtable
++
++.. flat-table::

+Subject: [PATCH] video: bcm2708_fb: Disable FB if no displays found
+
+If the firmware hasn't detected a display, the driver would assume
+one display was available, but because it had failed to retrieve the
+display size it would try to allocate a zero-sized buffer.
+
+Avoid the allocation failure by bailing out early if no display is
+found.

+Subject: [PATCH] zswap: Defer zswap initialisation
+
+Enabling zswap support in the kernel configuration costs about 1.5MB
+of RAM, even when zswap is not enabled at runtime. This cost can be
+reduced significantly by deferring initialisation (including pool
+creation) until the "enabled" parameter is set to true. There is a
+small cost to this in that some initialisation code has to remain in
+memory after the init phase, just in case they are needed later,
+but the total size increase is negligible.

+
+Upstream Linux deems using output GPIOs to generate IRQs as a bogus
+use case, even though the BCM2835 GPIO controller is capable of doing
+so. A number of users would like to make use of this facility, so
+disable the checks.

+
+The BRCM PCIe block has controls to enable control of the CLKREQ#
+signal by the L1SS, and to gate the refclk with the CLKREQ# input.
+These controls are mutually exclusive - the upstream code sets the
+latter, but some use cases require the former.
+
+Add a Device Tree property - brcm,enable-l1ss - to switch to the
+L1SS configuration.

+Subject: [PATCH] media: irs1125: Atomic access to imager reconfiguration
+
+Instead of changing the exposure and framerate settings for all sequences,
+they can be changed for every sequence individually now. Therefore the
+IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
+IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.
+
+The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG
+is removed.
+

+Subject: [PATCH] media: irs1125: Keep HW in sync after imager reset
+
+When closing the video device, the irs1125 is put in power down state.
+To keep V4L2 ctrls and the HW in sync, v4l2_ctrl_handler_setup is
+called after power up.
+
+The compound ctrl IRS1125_CID_MOD_PLL however has a default value
+of all zeros, which puts the imager into a non responding state.
+Thus, this ctrl is not written by the driver into HW after power up.
+The userspace has to take care to write senseful data.

+Subject: [PATCH] media: bcm2835-unicam: Driver for CCP2/CSI2 camera interface
+
+Add a driver for the Unicam camera receiver block on BCM283x processors.
+Compared to the bcm2835-camera driver present in staging, this driver
+handles the Unicam block only (CSI-2 receiver), and doesn't depend on
+the VC4 firmware running on the VPU.
+
+The commit is made up of a series of changes cherry-picked from the
+rpi-5.4.y branch of https://github.com/raspberrypi/linux/ with
+additional enhancements, forward-ported to the mainline kernel.

++ * CCP2 data and writes it into SDRAM.
++ * The only potential processing options are to repack Bayer data into an
++ * alternate format, and applying windowing.
++ * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P
++ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
++ * but not generically up to V4L2_PIX_FMT_Sxxxx16. The driver will add both
++ * formats where the relevant formats are defined, and will automatically
++ * configure the repacking as required.
++ * Support for windowing may be added later.
++ *
++ * It should be possible to connect this driver to any sensor with a
++ * suitable output interface and V4L2 subdevice driver.
++ *
++ * bcm2835-camera uses the VideoCore firmware to control the sensor,
++ * Unicam, ISP, and all tuner control loops. Fully processed frames are
++ * delivered to the driver by the firmware. It only has sensor drivers
++ * for Omnivision OV5647, and Sony IMX219 sensors.
++ *
++ * The two drivers are mutually exclusive for the same Unicam instance.
++ * The VideoCore firmware checks the device tree configuration during boot.
++ * If it finds device tree nodes called csi0 or csi1 it will block the
++ * firmware from accessing the peripheral, and bcm2835-camera will
++ * not be able to stream data.

+Subject: [PATCH] leds: Add the actpwr trigger
+
+The actpwr trigger is a meta trigger that cycles between an inverted
+mmc0 and default-on. It is written in a way that could fairly easily
+be generalised to support alternative sets of source triggers.

+
+Pi 0&1 pass all ARM accesses through the VPU L2 cache, therefore
+the dma-ranges property sets the cache alias bits to other
+than the direct alias, hence this WARN was firing.
+
+It was overprotective coding, so assume that everything is OK

+Subject: [PATCH] media: bcm2835-unicam: Always service interrupts
+
+From when bringing up the driver, there was a check in the isr
+to ignore interrupts (claiming them handled) should the driver
+not be streaming.
+
+The VPU now will not register a camera driver if it finds a
+CSI2 node enabled in device tree, therefore this flawed check is
+redundant.

+The change to retrieve the pixel format always on g_fmt didn't

+Correct this so that the packing setting is retained whereever

+Subject: [PATCH] media: bcm2835-unicam: change minimum number of vb2_queue
+ buffers to 1
+
+Since the unicam driver was modified to write to a dummy buffer when no
+user-supplied buffer is available, it can now write to and return a
+buffer even when there's only a single one. Enable this by changing the
+min_buffers_needed in the vb2_queue; it will be useful for enabling
+still captures without allocating more memory than absolutely necessary.

+Subject: [PATCH] staging/fbtft: Add support for display variants
+
+Display variants are intended as a replacement for the now-deleted
+fbtft_device drivers. Drivers can register additional compatible
+strings with a custom callback that can make the required changes
+to the fbtft_display structure.
+
+Start the ball rolling by adding adafruit18, adafruit18_green and
+sainsmart18 displays.

+Subject: [PATCH] net: bcmgenet: Reset RBUF on first open
+
+If the RBUF logic is not reset when the kernel starts then there
+may be some data left over from any network boot loader. If the
+64-byte packet headers are enabled then this can be fatal.
+
+Extend bcmgenet_dma_disable to do perform the reset, but not when
+called from bcmgenet_resume in order to preserve a wake packet.
+
+N.B. This different handling of resume is just based on a hunch -
+why else wouldn't one reset the RBUF as well as the TBUF? If this
+isn't the case then it's easy to change the patch to make the RBUF
+reset unconditional.

+V4L2_PIX_FMT_BGR32 is deprecated as it is ambiguous over where

+
+Swap to the newer V4L2_PIX_FMT_BGRX32 format.

+Subject: [PATCH] staging: vc04_services: Add new vc-sm-cma driver
+
+Add Broadcom VideoCore Shared Memory support.
+
+This new driver allows contiguous memory blocks to be imported
+into the VideoCore VPU memory map, and manages the lifetime of
+those objects, only releasing the source dmabuf once the VPU has
+confirmed it has finished with it.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: vcsm-cma: Fix memory leak from not detaching dmabuf
+
+When importing there was a missing call to detach the buffer,
+so each import leaked the sg table entry.
+
+Actually the release process for both locally allocated and
+imported buffers is identical, so fix them to both use the same
+function.

+staging/vc-sm-cma: Avoid log spamming on Pi0/1 over cache alias.
+
+Pi 0/1 use the 0x80000000 cache alias as the ARM also sees the world
+through the VPU L2 cache.
+vc-sm-cma was trying to ensure it was in an uncached alias (0xc), and
+complaining on every allocation if it weren't. Reduce this logging.

+
+vc-sm-cma: Restore correct cache maintainance operations
+
+We have been using the more expensive flush operations rather than
+invalidate and clean since kernel rpi-5.9.y
+
+These are exposed with:
+52f1453513ba95084ab811a030032fe605b0cbe2 Re-expose some dmi APIs for use in VCSM
+
+But I believe that commit was dropped when (non-cma) vc-sm was dropped,
+and didn't get updated when the commit was restored

++ * VideoCore Shared Memory driver using CMA.
++ *
++ * Copyright: 2018, Raspberry Pi (Trading) Ltd
++ * Dave Stevenson <dave.stevenson@raspberrypi.org>
++ *
++ * Based on vmcs_sm driver from Broadcom Corporation for some API,
++ * and taking some code for buffer allocation and dmabuf handling from
++ * videobuf2.
++ *
++ *
++ * This driver has 3 main uses:
++ * 1) Allocating buffers for the kernel or userspace that can be shared with the
++ *    VPU.
++ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
++ * 3) Allocating buffers for use by the VPU.
++ *
++ * In the first and second cases the native handle is a dmabuf. Releasing the
++ * resource inherently comes from releasing the dmabuf, and this will trigger
++ * unmapping on the VPU. The underlying allocation and our buffer structure are
++ * retained until the VPU has confirmed that it has finished with it.
++ *
++ * For the VPU allocations the VPU is responsible for triggering the release,
++ * and therefore the released message decrements the dma_buf refcount (with the
++ * VPU mapping having already been marked as released).

+Subject: [PATCH] staging: vc04_services: Add a V4L2 M2M codec driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds a V4L2 memory to memory device that wraps the MMAL
+video decode and video_encode components for H264 and MJPEG encode
+and decode, MPEG4, H263, and VP8 decode (and MPEG2 decode
+if the appropriate licence has been purchased).
+
+This patch squashes all the work done in developing the driver
+on the Raspberry Pi rpi-5.4.y kernel branch.
+Thanks to Kieran Bingham, Aman Gupta, Chen-Yu Tsai, and
+Marek Behún for their contributions. Please refer to the
+rpi-5.4.y branch for the full history.

+
+staging/bcm2835-codec: Ensure OUTPUT timestamps are always forwarded
+
+The firmware by default tries to ensure that decoded frame
+timestamps always increment. This is counter to the V4L2 API
+which wants exactly the OUTPUT queue timestamps passed to the
+CAPTURE queue buffers.
+
+Disable the firmware option.

+
+staging/vc04_services/codec: Add support for CID MPEG_HEADER_MODE

+
+staging/vc04_services/codec: Clear last buf dequeued flag on START
+

+
+During decode, setting the CAPTURE queue format was setting the crop
+rectangle to the requested height before aligning up the format to
+cater for simple clients that weren't expecting to deal with cropping
+and the SELECTION API.
+This caused problems on some resolution change events if the client
+didn't also then use the selection API.

+
+In order to effectively guarantee that a V4L2_EVENT_SOURCE_CHANGE

+Matches correct behaviour from DECODE and DEINTERLACE

+
+staging: bcm2835-codec: Allow decode res changed before STREAMON(CAPTURE)
+
+The V4L2 stateful video decoder API requires that you can STREAMON
+on only the OUTPUT queue, feed in buffers, and wait for the
+SOURCE_CHANGE event.
+This requires that we enable the MMAL output port at the same time
+as the input port, because the output port is the one that creates
+the SOURCE_CHANGED event.
+

+
+staging/bcm2835-codec: Do not send buffers to the VPU unless streaming
+
+With video decode we now enable both input and output ports on
+the component. This means that buffers will get passed to the VPU
+earlier than desired if they are queued befoer STREAMON.
+
+Check that the queue is streaming before sending buffers to the VPU.

+
+staging: bcm2835-codec: Format changed should trigger drain
+
+When a format changed event occurs, the spec says that it
+triggers an implicit drain, and that needs to be signalled
+via -EPIPE.
+
+For BCM2835, the format changed event happens at the point
+the format change occurs, so no further buffers exist from
+before the resolution changed point. We therefore signal the
+last buffer immediately.
+We don't have a V4L2 available to us at this point, so set
+the videobuf2 queue last_buffer_dequeued flag directly.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: bcm2835-codec: Signal the firmware to stop on all changes
+
+The firmware defaults to not stopping video decode if only the
+pixel aspect ratio or colourspace change. V4L2 requires us
+to stop decoding on any change, therefore tell the firmware
+of the desire for this alternate behaviour.

+
+staging: bcm2835-codec: Queue flushed buffers instead of completing
+
+When a buffer is returned on a port that is disabled, return it
+to the videobuf2 QUEUED state instead of DONE which returns it
+to the client.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: bcm2835_codec: Correct flushing code for refcounting
+
+Completions don't reference count, so setting the completion
+on the first buffer returned and then not reinitialising it
+means that the flush function doesn't behave as intended.
+
+Signal the completion when the last buffer is returned.

+
+staging: bcm2835-codec: Ensure all ctrls are set on streamon
+
+Currently the code was only setting some controls from
+bcm2835_codec_set_ctrls, but it's simpler to use
+v4l2_ctrl_handler_setup to avoid forgetting to adding new
+controls to the list.

+
+staging: bcm2835-codec: Add support for H&V Flips to ISP
+
+The ISP can do H & V flips whilst resizing or converting
+the image, so expose that via V4L2_CID_[H|V]FLIP.

+
+bcm2835-v4l2-codec: Remove advertised support of VP8
+
+The support for this format by firmware is very limited

+
+Pass V4L2_CID_MPEG_VIDEO_H264_MIN_QP/MAX_QP to bcm2835-v4l2-codec
+
+Following raspberrypi/linux#4704. This is necessary to set up
+quantization for variable bitrate to avoid video flickering.
+
+staging/bcm2835-codec: bytesperline for YUV420/YVU420 needs to be 64
+
+Matching https://github.com/raspberrypi/linux/pull/4419, the ISP
+block (which is also used on the input of the encoder, and output
+of the decoder) needs the base address of all planes to be aligned
+to multiples of 32. This includes the chroma planes of YUV420 and
+YVU420.
+If the height is only a multiple of 2 (not 4), then you get an odd
+number of lines in the second plane, which means the 3rd plane
+starts at a multiple of bytesperline/2.
+
+Set the minimum bytesperline alignment to 64 for those formats
+so that the plane alignment is always right.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging/bcm2835-codec: Allow a different stride alignment per role
+
+Deinterlace and decode aren't affected in the same way as encode
+and ISP by the alignment requirement on 3 plane YUV420.
+Decode would be affected, but it always aligns the height up to
+a macroblock, and uses the selection API to reflect that.
+
+Add in the facility to set the bytesperline alignment per role.

+
+staging: vc04_services: codec: Add support for V4L2_PIX_FMT_RGBA32 format
+
+We already support V4L2_PIX_FMT_BGR32 which is the same thing with red
+and blue swapped, so it makes sense to include this variant as well.
+
+Signed-off-by: David Plowman <david.plowman@raspberrypi.com>
+
+bcm2835-codec: Return empty buffers to the VPU instead of queueing to vbuf2
+
+The encoder can skip frames totally should rate control overshoot
+the target bitrate too far. In this situation it generates an
+output buffer of length 0.
+V4L2 treats a buffer of length 0 as an end of stream flag, which is
+not appropriate in this case, therefore we can not return that buffer
+to the client.
+
+The driver was returning the buffer to videobuf2 in the QUEUED state,
+however that buffer was then not dequeued again, so the number of
+buffers was reduced each time this happened. In the pathological
+case of using GStreamer's videotestsrc in mode 1 for noise, this happens
+sufficiently frequently to totally stall the pipeline.
+
+If the port is still enabled then return the buffer straight back to
+the VPU rather than to videobuf2.

+vc04_services: bcm2835-codec: Add support for V4L2_PIX_FMT_NV12_COL128
+
+V4L2_PIX_FMT_NV12_COL128 is supported by the ISP and the input of
+video_encode, output of video_decode, and both input and output
+of the ISP.
+
+Add in the plumbing to support the format on those ports.

+
+vc04_services: bcm2835-codec: Set crop_height for compressed formats
+
+In particular for the encoder where the CAPTURE format dictates
+the parameters given to the codec we need to be able to set the
+value passed as the crop_height for the compressed format.
+There's no crop available for cropped modes, so always set
+crop_height to the requested height.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+vc04_services: bcm2835-codec: Set port format from s_selection
+
+s_selection allows the crop region of an uncompressed pixel
+format to be specified, but it wasn't passing the setting on to
+the firmware. Depending on call order this would potentially
+mean that the crop wasn't actioned.
+
+Set the port format on s_selection if we have a component created.

+
+vc04_services: bcm2835-codec: Allow encoder_cmd on ISP and deinterlace
+
+ISP and deinterlace also need a mechanism for passing effectively
+an EOS through the pipeline to signal when all buffers have been
+processed.
+
+VIDIOC_ENCODER_CMD does exactly this for encoders, so reuse the same
+function for ISP and deinterlace.
+(VIDIOC_DECODER_CMD is slightly different in that it also passes
+details of when and how to stop, so is not as relevant).

+Subject: [PATCH] staging: vc04_services: ISP: Add a more complex ISP
+ processing component
+
+Driver for the BCM2835 ISP hardware block.  This driver uses the MMAL
+component to program the ISP hardware through the VC firmware.
+
+The ISP component can produce two video stream outputs, and Bayer
+image statistics. This can't be encompassed in a simple V4L2
+M2M device, so create a new device that registers 4 video nodes.
+
+This patch squashes all the development patches from the earlier
+rpi-5.4.y branch into one
+

+Subject: [PATCH] gpio: Add gpio-fsm driver
+
+The gpio-fsm driver implements simple state machines that allow GPIOs
+to be controlled in response to inputs from other GPIOs - real and
+soft/virtual - and time delays. It can:
++ create dummy GPIOs for drivers that demand them,
++ drive multiple GPIOs from a single input, with optional delays,
++ add a debounce circuit to an input,
++ drive pattern sequences onto LEDs
+etc.

+gpio-fsm: Fix a build warning

+
+gpio-fsm: Rename 'num-soft-gpios' to avoid warning
+
+As of 5.10, the Device Tree parser warns about properties that look
+like references to "suppliers" of various services. "num-soft-gpios"
+resembles a declaration of a GPIO called "num-soft", causing the value
+to be interpreted as a phandle, the owner of which is checked for a
+"#gpio-cells" property.
+
+To avoid this warning, rename the gpio-fsm property to "num-swgpios".
+

+
+gpio-fsm: Show state info in /sys/class/gpio-fsm
+
+Add gpio-fsm sysfs entries under /sys/class/gpio-fsm. For each state
+machine show the current state, which state (if any) will be entered
+after a delay, and the current value of that delay.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+gpio-fsm: Fix shutdown timeout handling
+
+The driver is intended to jump directly to a shutdown state in the
+event of a timeout during shutdown, but the sense of the test was
+inverted.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+gpio-fsm: Clamp the delay time to zero
+
+The sysfs delay_ms value is calculated live, and it is possible for
+the time left to appear to be negative briefly if the timer handling
+hasn't completed. Ensure the displayed value never goes below zero,
+for the sake of appearances.

+Subject: [PATCH] firmware: raspberrypi: Add support for tryonce reboot flag
+
+Define a new mailbox (SET_REBOOT_FLAGS) which may be used to
+pass optional flags to the Raspberry Pi firmware that changes
+the behaviour of the bootloader and firmware during a reboot.
+
+Currently this just defines the 'tryboot' flag which causes
+the firmware to load tryboot.txt instead config.txt. This
+alternate configuration file can be used to specify the
+path of an alternate firmware and kernels allowing a fallback
+mechanism to be implemented for OS upgrades.

+The last nibble is a revision ID, and the 54213pe is a later rev

+Subject: [PATCH] PCI: brcmstb: Restore initial fundamental reset
+
+[1] replaced a single reset function with a pointer to one of two
+implementations, but also removed the call asserting the reset
+at the start of brcm_pcie_setup. Doing so breaks Raspberry Pis with
+VL805 XHCI controllers lacking dedicated SPI EEPROMs, which have been
+used for USB booting but then need to be reset so that the kernel
+can reconfigure them. The lack of a reset causes the firmware's loading
+of the EEPROM image to RAM to fail, breaking USB for the kernel.
+
+See: https://www.raspberrypi.org/forums/viewtopic.php?p=1758157#p1758157

+Subject: [PATCH] drm/panel/raspberrypi-touchscreen: Use independent I2C
+ actions with delay.
+
+We now have the hardware I2C controller pinmuxed to the drive the
+display I2C, but this controller does not support clock stretching.
+The Atmel micro-controller in the panel requires clock stretching
+to allow it to prepare any data to be read.
+
+Split the rpi_touchscreen_i2c_read into two independent transactions with
+a delay between them for the Atmel to prepare the data.

+clk_disable_unprepare() is called unconditionally in stop_streaming().
+This is incorrect in the cases where start_streaming() fails, and
+unprepares all clocks as part of the failure cleanup. To avoid this,
+ensure that clk_disable_unprepare() is only called in stop_streaming()
+if the clocks are in a prepared state.

+lan78xx_link_reset explicitly clears the MAC's view of the PHY's IRQ
+status. In doing so it potentially leaves the PHY with a pending
+interrupt that will never be acknowledged, at which point no further
+interrupts will be generated.

+Avoid the problem by acknowledging any pending PHY interrupt after

+Subject: [PATCH] spi: bcm2835: Workaround/fix for zero-length transfers
+
+A relatively recent commit ([1]) contained optimisation for the PIO
+SPI FIFO-filling functions. The commit message includes the phrase
+"[t]he blind and counted loops are always called with nonzero count".
+This is technically true, but it is still possible for count to become
+zero before the loop is entered - if tfr->len is zero. Moving the loop
+exit condition to the end of the loop saves a few cycles, but results
+in a near-infinite loop should the revised count be zero on entry.
+
+Strangely, zero-lengthed transfers aren't filtered by the SPI framework
+and, even more strangely, the Python3 spidev library is triggering them
+for no obvious reason.
+
+Avoid the problem completely by bailing out of the main transfer
+function early if trf->len is zero, although there may be a case for
+moving the mitigation into the framework.
+
+See: https://github.com/raspberrypi/linux/issues/4100

+Subject: [PATCH] kbuild: Silence unavoidable dtc overlay warnings
+
+Much effort has been put into finding ways to avoid warnings from dtc
+about overlays, usually to do with the presence of #address-cells and
+size-cells, but not exclusively so. Since the issues being warned about
+are harmless, suppress the warnings to declutter the build output and
+to avoid alarming users.

+Subject: [PATCH] bcm2835-isp: Allow formats with different colour spaces.
+
+Each supported format now includes a mask showing the allowed colour
+spaces, as well as a default colour space for when one was not
+specified.
+
+Additionally we translate the colour space to mmal format and pass it
+over to the VideoCore.

+Subject: [PATCH] media: bcm2835-unicam: Fix bug in buffer swapping logic
+
+If multiple sets of interrupts occur simultaneously, it may be unsafe
+to swap buffers, as the hardware may already be re-using the current
+buffers. In such cases, avoid swapping buffers, and wait for the next
+opportunity at the Frame End interrupt to signal completion.
+
+Additionally, check the packet compare status when watching for frame
+end for buffers swaps, as this could also signify a frame end event.

+Subject: [PATCH] Assign crypto aliases to different AES implementation modules
+
+The kernel modules aes-neon-blk and aes-neon-bs perform poorly, at least on
+Cortex-A72 without crypto extensions. In fact, aes-arm64 outperforms them
+on benchmarks, despite it being a simpler implementation (only accelerating
+the single-block AES cipher).
+
+For modes of operation where multiple cipher blocks can be processed in
+parallel, aes-neon-bs outperforms aes-neon-blk by around 60-70% and aes-arm64
+is another 10-20% faster still. But the difference is even more marked with
+modes of operation with dependencies between neighbouring blocks, such as
+CBC encryption, which defeat parallelism: in these cases, aes-arm64 is
+typically around 250% faster than either aes-neon-blk or aes-neon-bs.
+
+The key trade-off with aes-arm64 is that the look-up tables are situated in
+RAM. This leaves them potentially open to cache timing attacks. The two other
+modules, by contrast, load the look-up tables into NEON registers and so are
+able to perform in constant time.
+
+This patch aims to load aes-arm64 more often.
+
+If none of the currently-loaded crypto modules implement a given algorithm,
+a new one is typically selected for loading using a platform-neutral alias
+describing the required algorithm. To enable users to still
+load aes-neon-blk or aes-neon-bs if they really want them, while still
+ensuring that aes-arm64 is usually selected, remove the aliases from
+aes-neonbs-glue.c and aes-glue.c and apply them to aes-cipher-glue.c, but
+still build the two NEON modules.
+
+Since aes-glue.c can also be used to build aes-ce-blk, leave them enabled
+if USE_V8_CRYPTO_EXTENSIONS is defined, to ensure they are selected if we
+in future use a CPU which has the crypto extensions enabled.
+
+Note that the algorithm priority specifiers are unchanged, so if
+aes-neon-bs is loaded at the same time as aes-arm64, the former will be
+used in preference. However, aes-neon-blk and aes-arm64 have tied priority,
+so whichever module was loaded first will be used (assuming aes-neon-bs is
+not loaded).

+Subject: [PATCH] media: ov5647: Fix return codes from ov5647_write/ov5647_read
+ functions.
+
+Previously they were returning positive non-zero codes for success,
+which were getting passed up the call stack. Since release 4.19,
+do_dentry_open (fs/open.c) has been catching these and flagging an
+error. (So this driver has been broken since that date.)

+
+DMABUFs are all handled by videobuf2, so there is no reason not
+to enable support for them.
+
+Note that this driver is still using the vmalloc allocator, so
+the buffers it allocates will not be compatible with the codec
+or ISP driver that require contiguous buffers. However this
+driver should be able to import the buffers allocated by them.

+There is no reason why the control GPIOs for the panel can not
+be connected to I2C or similar GPIO interfaces that may need to
+sleep, therefore switch from gpiod_set_value to
+gpiod_set_value_cansleep calls to configure them.
+Without that you get complaints from gpiolib every time the state

+The result of dividing a u32 by a size_t is an unsigned int on arm32
+and a long unsigned int on arm64. Use "%zu" (the size_t format) to
+remove the build warning for 64-bit builds.

+Subject: [PATCH] staging: vc04_services: isp: Set the YUV420/YVU420 format
+ stride to 64 bytes
+
+The bcm2835 ISP requires the base address of all input/output planes to have 32
+byte alignment. Using a Y stride of 32 bytes would not guarantee that the V
+plane would fulfil this, e.g. a height of 650 lines would mean the V plane
+buffer is not 32 byte aligned for YUV420 formats.
+
+Having a Y stride of 64 bytes would ensure both U and V planes have a 32 byte
+alignment, as the luma height will always be an even number of lines.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The vidioc_enum_input() v4l2 ioctl is capable of returning
+sensor/input status as well. This is used in current
+GStreamer HEAD for signal detection [1].
+
+bcm2835-unicam does handle this syscall, but it didn't ask
+the subdevice driver about the input status. The input then
+appeared as always present.
+
+This commit adds the necessary query. There is a precedent for
+this - the R-Car VIN V4L2 driver does a similar call [2].

+Subject: [PATCH] usb: xhci: workaround for bogus SET_DEQ_PENDING endpoint
+ state
+
+See https://github.com/raspberrypi/linux/issues/3981
+
+An unknown unsafe memory access can result in the ep_state variable
+in xhci_virt_ep being trampled with a stuck SET_DEQ_PENDING state
+despite successful completion of a Set TR Deq Pointer command.
+
+All URB enqueue/dequeue calls for the endpoint will fail in this state
+so no transfers are possible until the device is reconnected.
+
+As a workaround, clear the flag if we see it set and issue a new Set
+TR Deq command anyway - this should be harmless, as a prior Set TR Deq
+command will only have been issued in the Stopped state, and if the
+endpoint is Running then the controller is required to ignore it and
+respond with a Context State Error event TRB.

+Subject: [PATCH] staging: vchiq_arm: Add 36-bit address support
+
+Conditional on a new compatible string, change the pagelist encoding
+such that the top 24 bits are the pfn, leaving 8 bits for run length
+(-1), giving a 36-bit address range.
+
+Manage the split between addresses for the VPU and addresses for the
+40-bit DMA controller with a dedicated DMA device pointer that on non-
+BCM2711 platforms is the same as the main VCHIQ device. This allows
+the VCHIQ node to stay in the usual place in the DT.

+Subject: [PATCH] staging: vchiq_arm: Usa a DMA pool for small bulks
+
+During a bulk transfer we request a DMA allocation to hold the
+scatter-gather list.  Most of the time, this allocation is small
+(<< PAGE_SIZE), however it can be requested at a high enough frequency
+to cause fragmentation and/or stress the CMA allocator (think time
+spent in compaction here, or during allocations elsewhere).
+
+Implement a pool to serve up small DMA allocations, falling back
+to a coherent allocation if the request is greater than
+VCHIQ_DMA_POOL_SIZE.

+Subject: [PATCH] drm/panel-simple: Add a timing for the Raspberry Pi 7" panel
+
+The Raspberry Pi 7" 800x480 panel uses a Toshiba TC358762 DSI
+to DPI bridge chip, so there is a requirement for the timings
+to be specified for the end panel. Add such a definition.

+Subject: [PATCH] staging: mmal-vchiq: Reset buffers_with_vpu on port_enable
+
+Should we go through the timeout failure case with port_disable
+not returning all buffers for whatever reason, the
+buffers_with_vpu counter gets left at a non-zero value, which
+will cause reference counting issues should the instance be
+reused.
+
+Reset the count when the port is enabled again, but before
+any buffers have been sent to the VPU.

+Subject: [PATCH] media/bcm2835-unicam: Parse pad numbers correctly
+
+The driver was making big assumptions about the source device
+using pad 0 and 1, which doesn't follow for more complex
+devices where Unicam's source device may be a sink device for
+something else.
+
+Read the pad numbers through media controller, and reference
+them appropriately.

+ API
+
+Adds Media Controller API support for more complex pipelines.
+libcamera is about to switch to using this mechanism for configuring
+sensors.
+
+This can be enabled by either a module parameter, or device tree.
+
+Various functions have been moved to group video-centric and
+mc-centric functions together.
+
+Based on a similar conversion done to ti-vpe.

+media: bcm2835-unicam: Fixup for 5.18 and new get_mbus_config struct
+
+The number of active CSI2 data lanes has moved within the struct
+v4l2_mbus_config used by the get_mbus_config API call.
+Update the driver to match the changes in mainline.

+Subject: [PATCH] brcmfmac: Don't promote INFO logging to ERR
+
+An unwanted side effect of enabling the BRCMDBG config setting is
+redefining brcmf_info to be brcmf_err. This can be alarming to users
+and makes it harder to spot real errors, so don't do it.

+Subject: [PATCH] drivers: bcm2835_isp: Allow multiple users for the ISP
+ driver.
+
+Add a second (identical) set of device nodes to allow concurrent use of the ISP
+hardware by another user. This change effectively creates a second state
+structure (struct bcm2835_isp_dev) to maintain independent state for the second
+user. Node and media entity names are appened with the instance index
+appropriately.
+
+Further users can be added by changing the BCM2835_ISP_NUM_INSTANCES define.

+Subject: [PATCH] regulator/rpi-panel-attiny: Don't read the LCD power status
+
+The I2C to the Atmel is very fussy, and locks up easily on
+Pi0-3 particularly on reads.
+
+The LCD power status is controlled solely by this driver, so
+rather than reading it back from the Atmel, use the cached
+status last set.

+Subject: [PATCH] xhci: quirks: add link TRB quirk for VL805
+
+The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint
+being set to a Link TRB. The hardware-maintained endpoint context ends up
+stuck at the address of the Link TRB, leading to erroneous ring expansion
+events whenever the enqueue pointer wraps to the dequeue position.
+
+If the search for the end of the current TD and ring cycle state lands on
+a Link TRB, move to the next segment.

+Subject: [PATCH] usb: xhci: add VLI_TRB_CACHE_BUG quirk
+
+The VL805 fetches up to 4 transfer TRBs at a time. TRB reads don't cross
+a 64B boundary, and if a TRB is fetched and is not on a 64B boundary,
+the read is sized up to the next 64B boundary.
+
+However the VL805 implements a readahead prefetch for TRBs on a transfer
+ring. This fetches the next 64B after any TRB read has happened. Near
+the end of a ring segment, the prefetcher can read the first 64B of the
+next page in physical memory and this is where the behaviour causes a
+bug.
+
+The controller does not tag reads with which endpoint they are for, so
+if the start of the next page is a ring segment used by a victim
+endpoint, and the victim endpoint is about to fetch TRBs from the start
+of the segment, the victim endpoint will read from the prefetched data
+and not perform a read to main memory. If the data is stale, the ring
+cycle state bit may not be correct and the endpoint will silently halt.
+
+Adjust trbs_per_seg for transfer rings allocated for this controller.
+
+See https://github.com/raspberrypi/linux/issues/4685

+
+https://github.com/raspberrypi/linux/issues/4440
+
+Upstream has added additional device specific controls, so the
+V4L2_CID_USER_BASE + 0x10e0 value that had been defined for use with
+the ISP has been taken by something else (and +0x10f0 has been used as
+well)
+
+Duplicate the use on V4L2_CID_USER_BASE + 0x10e0 so that userspace
+(libcamera) doesn't need to change. Once the driver is upstream, then
+we'll update libcamera to adopt the new value as it then won't change.

+Subject: [PATCH] media: i2c: ov9281: Increase diff between VTS and max
+ exposure
+
+The driver did allow the exposure to go up to VTS - 4 lines,
+but this would produce a visible line on 1280x800, and a stall of
+the sensor at 640x480.
+
+Whilst it appears to work with a difference of 5, the datasheet states
+there should be at least 25 lines difference between VTS and exposure,
+so use that value.

+Subject: [PATCH] drivers: bcm2835_unicam: Disable trigger mode operation
+
+On a Pi3 B/B+ platform the imx219 sensor frequently generates a single corrupt
+frame when the sensor first starts. This can either be a missing line, or
+invalid samples within the line. This only occurrs using the Unicam kernel
+driver.
+
+Disabling trigger mode elimiates this corruption. Since trigger mode is a
+legacy feature copied from the firmware driver and not expected to be needed,
+remove it. Tested on the Raspberry Pi cameras and shows no ill effects.

+  1 warning generated.
+
+If the first ov9281_read_reg() call fails, id_msb will be used
+uninitialized. However, this warning does not actually matter in
+practice because the value of id is not used when either call to
+ov9281_read_reg() fails, as the boolean OR will short circuit due to the
+ret condition being checked first. Regardless, it is not good to use
+variables uninitialized so silence the warning by initializing id_msb to
+0, as was done with id.

+
+The default clock-stretch timeout is 35 mS, which works well for
+SMBus, but there are some I2C devices which can stretch the clock even
+longer. Rather than trying to prescribe a safe default for everyone,
+allow the timeout to be configured.

+Subject: [PATCH] dt-bindings: display: simple: add Geekworm MZP280 Panel
+
+The Geekworm MZP280 panel is a 480x640 (portrait) panel with a
+capacitive touch interface and a 40 pin header meant to interface
+directly with the Raspberry Pi. The screen is 2.8 inches diagonally,
+and there appear to be at least 4 distinct versions all with the same
+panel timings.
+
+Timings were derived from drivers posted on the github located here:
+https://github.com/tianyoujian/MZDPI/tree/master/vga
+
+Additional details about this panel family can be found here:
+https://wiki.geekworm.com/2.8_inch_Touch_Screen_for_Pi_zero

+Subject: [PATCH] drm/panel: Add panel driver for TDO Y17B based panels
+
+The Top DisplayOptoelectronics (TDO) T17B driver chip is used
+in the TL040HDS20CT panel (found in the Pimoroni HyperPixel4
+Square display) and potentially other displays.
+The driver chip supports SPI for  configuration and DPI
+video data.

+Subject: [PATCH] usb: xhci: add a quirk for Superspeed bulk OUT transfers on
+ VL805
+
+The VL805 has a bug in its internal FIFO space accounting that results
+in bulk OUT babble if a TRB in a large multi-element TD has a data
+buffer size that is larger than and not a multiple of wMaxPacketSize for
+the endpoint. If the downstream USB3.0 link is congested, or latency is
+increased through an intermediate hub, then the VL805 enters a suspected
+FIFO overflow condition and transmits repeated, garbled data to the
+endpoint.
+
+TDs with TRBs of exact multiples of wMaxPacketSize and smaller than
+wMaxPacketSize appear to be handled correctly, so split buffers at a
+1024-byte length boundary and put the remainder in a separate smaller
+TRB.

+Subject: [PATCH] drivers: staging: bcm2835-isp: Do not cleanup mmal vcsm
+ buffer on stop_streaming
+
+On stop_streaming() the vcsm buffer handle gets released by the buffer cleanup
+code.  This will subsequently cause and error if userland re-queues the same
+buffer on the next start_streaming() call.
+
+Remove this cleanup code and rely on the vb2_ops->buf_cleanup() call to do the
+cleanups instead.

+Subject: [PATCH] media: i2c: Rename ad5398 to ad5398_vcm
+
+There's already a regulator module called ad5398 that exposes
+this device through the regulator API. That is meaningless in
+the terms that it uses and how it maps to V4L2, so a new driver
+was added. However the module name collision wasn't noted, so
+rename it now.

+Subject: [PATCH] mm,page_alloc,cma: introduce a customisable threshold for
+ allocating pages in cma
+
+On some platforms the cma area can be half the entire system memory,
+meaning that allocations start happening in the cma area immediately.
+This leads to fragmentation and subsequent fatal cma_alloc failures.
+
+We introduce an "alloc_in_cma_threshold" parameter which requires that

+
+The panel sends MIPI DCS commands during prepare and is expecting
+the bus to remain in LP-11 state in-between.
+
+Set the prepare_upstream_first flag so that the upstream DSI host
+is prepared / pre_enabled first, and therefore the bus is in a

+Subject: [PATCH] thermal: broadcom: Use dev_err_probe to suppress defer errors
+
+It is quite common for the devm_thermal_zone_of_sensor_register
+to need to defer, so avoid spamming the log by using
+dev_err_probe instead of dev_err.

+Subject: [PATCH] mmc: block: Don't do single-sector reads during recovery
+
+See https://github.com/raspberrypi/linux/issues/5019
+
+If an SD card has degraded performance such that IO operations time out
+then the MMC block layer will leak SG DMA mappings in the swiotlb during
+recovery. It retries the same SG and this causes the leak, as it is
+mapped twice - once in sdhci_pre_req() and again during single-block
+reads in sdhci_prepare_data().
+
+Resetting the card (including power-cycling if a regulator for vmmc is
+present) ought to be enough to recover a stuck state, so for now don't
+try single-block reads in the recovery path.

+
+Stephen reported that a static key warning splat appears during early
+boot on systems that credit randomness from device trees that contain an
+"rng-seed" property, because because setup_machine_fdt() is called
+before jump_label_init() during setup_arch():

+
+A trivial fix went in to address this on arm64, 73e2d827a501 ("arm64:
+Initialize jump labels before setup_machine_fdt()"). But it appears that
+fixing it on other platforms might not be so trivial. Instead, defer the
+setting of the static branch until later in the boot process.

+9152x6944 10-bit @ 2.7fps
+4624x3472 10-bit (binned) @ 10fps
+3840x2160 10-bit (cropped/binned) @ 20fps
+2312x1736 10-bit (binned) @ 30fps
+1920x1080 10-bit (cropped/binned) @ 60fps
+1280x720 10-bit (cropped/binned) @ 120fps

+Subject: [PATCH] media: i2c: arducam_64mp: Advertise embedded data node on
+ media pad 1
+
+This commit updates the arducam_64mp driver to adverise support for
+embedded data streams.
+
+The arducam_64mp sensor subdevice overloads the media pad to differentiate
+between image stream (pad 0) and embedded data stream (pad 1) when
+performing the v4l2_subdev_pad_ops functions.

+snd_bcm2835: disable HDMI audio when vc4 is used (#3640)
+
+Things don't work too well when both the vc4 driver and the firmware
+driver are trying to control the same audio output:
+
+[  763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
+
+Hence, when the vc4 HDMI driver is used, let it control audio. This is done
+by introducing a new device tree property to the audio node, and
+extending the vc4-kms-v3d overlays to set it appropriately.

+Add a property to allow the headphone output to be disabled. Use an

+
+Commit "ARM: dts: Adopt the upstream snd_bcm2835 handling" removed the
+audio section from the DT and the driver can no longer access the
+referenced firmware node 'brcm,firmware'. Fix that by searching for a
+compatible firmware node instead, similar to drivers/gpu/drm/vc4.

+
+Since commit "staging: bcm2835-audio: Add disable-headphones flag" the

+
+A VTS of 421 in the 640x400 mode only streams at 130.2fps
+instead of the expected ~261fps. This appears to be an invalid

+Subject: [PATCH] media: bcm2835-unicam: Correctly handle FS + FE ISR condtion
+
+If we get a simultaneous FS + FE interrupt for the same frame, it cannot be
+marked as completed and returned to userland as the framebuffer will be refilled
+by Unicam on the next sensor frame. Additionally, the timestamp will be set to 0
+as the FS interrupt handling code will not have run yet.
+
+To avoid these problems, the frame is considered dropped in the FE handler,
+and will be returned to userland on the subsequent sensor frame.

+Subject: [PATCH] media: video-mux: Read CSI2 config from FW, and pass to
+ receiver
+
+There is no obligation for all source devices on a video-mux to
+require the same bus configuration, so read the configuration
+from the sink ports, and relay via get_mbus_config on the source
+port.
+If the sources support get_mbus_config, then call that first.

+Subject: [PATCH] media: bcm2835-unicam: Fix for possible dummy buffer overrun
+
+The Unicam hardware has been observed to cause a buffer overrun when using the
+dummy buffer as a circular buffer. The conditions that cause the overrun are not
+fully known, but it seems to occur when the memory bus is heavily loaded.
+
+To avoid the overrun, program the hardware with a buffer size of 0 when using
+the dummy buffer. This will cause overrun into the allocated dummy buffer, but
+avoid out of bounds writes.

+Subject: [PATCH] usb: xhci: expand mitigations for VLI_SS_BULK_OUT_BUG quirk
+
+The VL805 can cause data corruption if a SS Bulk OUT endpoint enters a
+flow-control condition and there are TRBs in the transfer ring that are
+not an integral size of wMaxPacket and the endpoint is behind one or more
+hubs.
+
+This is frequently the case encountered when FAT32 filesystems are
+present on mass-storage devices with cluster sizes of 1 sector, and the
+filesystem is being written to with an aggregate of small files.
+
+The initial implementation of this quirk separated TRBs that didn't
+adhere to this limitation into two - the first a multiple of wMaxPacket
+and the second the 512-byte remainder - in an attempt to force TD
+fragments to align with packet boundaries. This reduced the incidence
+rate of data corruption but did not resolve it.
+
+The fix as recommended by VIA is to disable bursts if this sequence of
+TRBs can occur.
+
+Limit turning off bursts to just USB mass-storage devices by searching
+the device's configuration for an interface with a class type of
+USB_CLASS_MASS_STORAGE.

+Subject: [PATCH] usb: xhci: account for num_trbs_free when invalidating TDs
+
+If a ring has a number of TDs enqueued past the dequeue pointer, and the
+URBs corresponding to these TDs are dequeued, then num_trbs_free isn't
+updated to show that these TDs have been converted to no-ops and
+effectively "freed". This means that num_trbs_free creeps downwards
+until the count is exhausted, which then triggers xhci_ring_expansion()
+and effectively leaks memory by infinitely growing the transfer ring.
+
+This is commonly encounted through the use of a usb-serial port where
+the port is repeatedly opened, read, then closed.
+
+Move the num_trbs_free crediting out of the Set TR Dequeue Pointer
+handling and into xhci_invalidate_cancelled_tds().
+
+There is a potential for overestimating the actual space on the ring if
+the ring is nearly full and TDs are arbitrarily enqueued by a device
+driver while it is dequeueing them, but dequeues are usually batched

+Subject: [PATCH] brcmfmac: Read alternative firmware names from DT
+
+Add the ability to load the names of alternative firmwares from the
+Device Tree node. This permits separate firmwares for 43436s and 43438
+and allows downstream firmwares to coexist with upstream.

+Subject: [PATCH] drivers: usb: dwc_otg: fix reference passing when checking
+ bandwidth
+
+The pointer (struct usb_host_endpoint *)->hcpriv should contain a
+reference to dwc_otg_qh_t if the driver has already seen a URB submitted
+to this endpoint.
+
+It then checks whether the qh exists and is already in a schedule in
+order to decide whether to allocate periodic bandwidth or not. Passing a
+pointer to an offset inside of struct usb_host_endpoint instead of just
+the pointer means it dereferences bogus addresses.
+
+Rationalise (delete) a variable while we're at it.
+

+Subject: [PATCH] drivers: dwc_otg: stop GCC from patching FIQ functions
+
+Configuring GCC to use task stack protector canaries means it will
+insert calls to check functions in FIQ code. This is bad, as a) the
+FIQ's stack is banked and b) the failure invokes __stack_chk_fail which
+eventually tries to call printk(). Printing to the console inside the
+FIQ is generally fatal.
+
+Add CFLAGS to stop this happening in FIQ code.
+
+Also catch one function where notrace wasn't specified.

+Subject: [PATCH] overlays: pisound: Make button pins owned by card
+
+The pisound overlay claims a number of GPIOs using a pinctrl node, but
+for some reason hangs this claim on the main gpio node. This obscures
+the ownership of the pins (as shown by gpioinfo and in the kernel logs)
+and isn't scalable - only one overlay can use the trick at a time.
+
+Change the overlay to make the pin ownership clear and avoid any future
+conflicts, removing a bogus claim on pins_spi0 at the same time.

+Subject: [PATCH] firmware: raspberrypi: Introduce rpi_firmware_find_node()
+
+A significant number of RaspberryPi drivers using the firmware don't
+have a phandle to it, so end up scanning the device tree to find a node
+with the firmware compatible.
+
+That code is duplicated everywhere, so let's introduce a helper instead.

+Subject: [PATCH] drm/vc4: hdmi: Fix hdmi_enable_4kp60 detection
+
+In order to support higher HDMI frequencies, users have to set the
+hdmi_enable_4kp60 parameter in their config.txt file.
+
+We were detecting this so far by calling clk_round_rate() on the core
+clock with the frequency we're supposed to run at when one of those
+modes is enabled. Whether or not the parameter was enabled could then be
+inferred by the returned rate since the maximum clock rate reported by
+the firmware was one of the side effect of setting that parameter.
+
+However, the recent clock rework we did changed what clk_round_rate()
+was returning to always return the minimum allowed, and thus this test
+wasn't reliable anymore.
+
+Let's use the new clk_get_max_rate() function to reliably determine the
+maximum rate allowed on that clock and fix the 4k@60Hz output.
+
+Fixes: e9d6cea2af1c ("clk: bcm: rpi: Run some clocks at the minimum rate allowed")

+
+In order to support higher HDMI frequencies, users have to set the
+hdmi_enable_4kp60 parameter in their config.txt file.
+
+This will have the side-effect of raising the maximum of the core clock,
+tied to the HVS, and managed by the HVS driver.
+
+However, we are querying this in the HDMI driver by poking into the HVS
+structure to get our struct clk handle.
+
+Let's make this part of the HVS bind implementation to have all the core
+clock related setup in the same place.

+Subject: [PATCH] drm/vc4: hdmi: Add more checks for 4k resolutions
+
+At least the 4096x2160@60Hz mode requires some overclocking that isn't
+available by default, even if hdmi_enable_4kp60 is enabled.
+
+Let's add some logic to detect whether we can satisfy the core clock
+requirements for that mode, and prevent it from being used otherwise.

+Subject: [PATCH] drm/vc4: Make sure we don't end up with a core clock too high
+
+Following the clock rate range improvements to the clock framework,
+trying to set a disjoint range on a clock will now result in an error.
+
+Thus, we can't set a minimum rate higher than the maximum reported by
+the firmware, or clk_set_min_rate() will fail.
+
+Thus we need to clamp the rate we are about to ask for to the maximum
+rate possible on that clock.

+Subject: [PATCH] net: phy: BCM54210PE does not support PTP
+
+BCM54213PE is an Ethernet PHY that supports PTP hardware timestamping.
+BCM54210PW ia another Ethernet PHY, but one without PTP support.
+Unfortunately the two PHYs return the same ID when queried, so some
+extra information is required to determine whether the PHY is PTP-
+capable.
+
+There are two Raspberry Pi products that use these PHYs - Pi 4B and
+CM4 - and fortunately they use different PHY addresses, so use that as
+a differentiator. Choose to treat a PHY with the same ID but another
+address as a BCM54210PE, which seems more common.

+Subject: [PATCH] drm/vc4_hdmi: Allow hotplug detect to be forced
+
+See: https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off
+
+While the kernel provides a :D flag for assuming device is connected,
+it doesn't stop this function from being called and generating a cec_phys_addr_invalidate
+message when hotplug is deasserted.
+
+That message provokes a flurry of CEC messages which for many users results in the TV
+switching back on again and it's very hard to get it to stay switched off.
+
+It seems to only occur with an AVR and TV connected but has been observed across a
+number of manufacturers.
+
+The issue started with https://github.com/raspberrypi/linux/pull/4371
+and this provides an optional way of getting back the old behaviour

+Subject: [PATCH] media: adv7180: Nasty hack to allow input selection.
+
+Whilst the adv7180 driver support s_routing, nothing else
+does, and there is a missing lump of framework code to
+define the mapping from connectors on a board to the inputs
+they represent on the ADV7180.
+
+Add a nasty hack to take a module parameter that is passed in
+to s_routing on any call to G_STD, or S_STD (or subdev
+g_input_status call).

+Subject: [PATCH] usb: xhci: add XHCI_VLI_HUB_TT_QUIRK
+
+The integrated USB2.0 hub in the VL805 chipset has a bug where it
+incorrectly determines the remaining available frame time before the
+host next sends a SOF packet with an incremented frame_number.
+
+See the USB2.0 specification sections 11.3 and 11.14.2.3.
+
+The hub's non-periodic TT handler can transmit the IN/OUT handshake
+token too late, so a following 64-byte DATA0/1 packet causes the ACK
+handshake to collide with the propagated SOF. This causes port babble.
+
+Avoid ringing doorbells for vulnerable endpoints during uFrame 7 if the
+TR is Idle to stop one source of babble. An IN transfer for a Running TR
+may happen at any time, so there's not much we can do about that.
+
+Ideally a hub firmware update to properly implement frame timeouts is
+needed, and to avoid spinning for up to 125us when submitting TDs to
+Idle rings.

+Subject: [PATCH] vc4_hdmi: Avoid log spam for audio start failure
+
+We regularly get dmesg error reports of:
+[   18.184066] hdmi-audio-codec hdmi-audio-codec.3.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -19
+[   18.184098]  MAI: soc_pcm_open() failed (-19)
+
+Currently I get 30 of these when booting to desktop.
+We always say, ignore they are harmless, but removing them would be good.
+
+A bit of investigation shows, for me, the errors are all generated by second, unused hdmi interface.
+
+It shows as an alsa device, and pulseaudio attempts to open it (numerous times), generating a kernel
+error message each time.
+
+systemctl --user restart pulseaudio.service generates 6 additional error messages.
+
+The error messages all come through:
+https://github.com/raspberrypi/linux/blob/a009a9c0d79dfec114ee5102ec3d3325a172c952/sound/soc/soc-pcm.c#L39
+
+which suggests returning ENOTSUPP, rather that ENODEV will be quiet. And indeed it is.
+
+Note: earlier kernels do not have the quiet ENOTSUPP, so additional cherry-picks will be needed to backport

+Since we've recently added a ton of tests, the list starts to be a bit

+Let's order it alphabetically.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As the number of kunit tests in KMS grows further, we start to have
+multiple test suites that, for example, need to register a mock DRM
+driver to interact with the KMS function they are supposed to test.
+
+Let's add a file meant to provide those kind of helpers to avoid
+duplication.

+Subject: [PATCH] drm/vc4: kms: Sort the CRTCs by output before assigning them
+
+On the vc4 devices (and later), the blending is done by a single device
+called the HVS. The HVS has three FIFO that can operate in parallel, and
+route their output to 6 CRTCs and 7 encoders on the BCM2711.
+
+Each of these CRTCs and encoders have some constraints on which FIFO
+they can feed from, so we need some code to take all those constraints
+into account and assign FIFOs to CRTCs.
+
+The problem can be simplified by assigning those FIFOs to CRTCs by
+ascending output index number. We had a comment mentioning it already,
+but we were never actually enforcing it.
+
+It was working still in most situations because the probe order is
+roughly equivalent, except for the (optional, and fairly rarely used on
+the Pi4) VEC which was last in the probe order sequence, but one of the
+earliest device to assign.
+
+This resulted in configurations that were rejected by our code but were
+still valid with a different assignment.
+
+We can fix this by making sure we assign CRTCs to FIFOs by ordering
+them by ascending HVS output index.
+
+Fixes: 87ebcd42fb7b ("drm/vc4: crtc: Assign output to channel automatically")

+It makes more sense to register the CRTC before the encoder and

+
+It's fairly hard to figure out the instance of the CRTC affected by an

+
+Since we can provide our own to the CRTC initialization functions, let's
+do so to make the debugging sessions easier.

+Subject: [PATCH] drm/tests: helpers: Allow for a custom device struct to be
+ allocated
+
+The current helper to allocate a DRM device doesn't allow for any
+subclassing by drivers, which is going to be troublesome as we work on
+getting some kunit testing on atomic modesetting code.
+
+Let's use a similar pattern to the other allocation helpers by providing
+the structure size and offset as arguments.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We'll need a function that looks up an encoder by its vc4_encoder_type.
+Such a function is already present in the CRTC code, so let's make it
+public so that we can reuse it in the unit tests.

+Subject: [PATCH] drm/vc4: tests: Introduce a mocking infrastructure
+
+In order to test the current atomic_check hooks we need to have a DRM
+device that has roughly the same capabilities and layout that the actual
+hardware. We'll also need a bunch of functions to create arbitrary
+atomic states.
+
+Let's create some helpers to create a device that behaves like the real
+one, and some helpers to maintain the atomic state we want to check.

+Subject: [PATCH] drm/vc4: tests: Fail the current test if we access a register
+
+Accessing a register when running under kunit is a bad idea since our
+device is completely mocked.
+
+Fail the current test if we ever access any of our hardware registers.

+From 4f31b7e7b08f1e18f01d7840eea219016e7b4202 Mon Sep 17 00:00:00 2001

+Date: Mon, 14 Nov 2022 16:06:22 +0100
+Subject: [PATCH] drm/vc4: tests: Add unit test suite for the PV muxing
+
+The HVS to PixelValve muxing code is fairly error prone and has a bunch
+of arbitrary constraints due to the hardware setup.
+
+Let's create a test suite that makes sure that the possible combinations
+work and the invalid ones don't.

++KUnit Tests
++===========
++
++The VC4 Driver uses KUnit to perform driver-specific unit and
++integration tests.
++
++These tests are using a mock driver and can be ran using the
++command::
++	./tools/testing/kunit/kunit.py run \
++		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
++		--cross_compile aarch64-linux-gnu- --arch arm64
++
++Parts of the driver that are currently covered by tests are:
++ * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7
++   and BCM2711.
++
+ Memory Management and 3D Command Submission

+Subject: [PATCH] net: bcmgenet: Add 'eee' module parameter
+
+On some switches, having EEE enabled causes the link to become
+unstable. With this patch, adding 'genet.eee=N' to the kernel command
+line will cause EEE to be disabled on the link.

+Subject: [PATCH] dts: bcm2711: Add 'eee' dtparam
+
+The 'eee' dtparam allows EEE to be disabled on the onboard Ethernet
+controller. Adding 'dtparam=eee=off' to config.txt causes
+'genet.eee=N' to be added to the kernel command line, which in turn
+tells the Genet driver to disable EEE.

+
+The legacy camera stack wiring instructions connect the cameras
+to the opposite sets of GPIOs compared to the arrangement
+more normally used with libcamera on all other platforms.
+
+Add an overlay to allow easy swapping of the assignments so
+that the legacy wiring can be used with libcamera.

+Subject: [PATCH] dt: Correct cam_reg GPIO assignments for CM1&3.
+
+The standard instructions for wiring up cameras on CM1&3
+assign GPIOs for both the shutdown and LED pins on the
+camera connectors.
+The assignment in DT matched the LED wiring, not the shutdown
+line, so didn't control the camera power correctly.
+
+Update the base DT accordingly.

+Subject: [PATCH] overlays: audremap: Fix setting of the pin function
+
+The brcm,function property must be set in the overlay fragment too -
+otherwise the parametrization won't work. At least that's the case for
+bcm2711-rpi-cm4.dts which starts with empty properties:
+
+&gpio {
+        audio_pins: audio_pins {
+                brcm,pins = <>;
+                brcm,function = <>;
+        };
+};
+
+This was broken since a56df85d2f42fd461fdc05f33617141aca5ba465.

+ driver
+
+The DW9817 is effectively the same as DW9807 from a programming
+interface, however it drives +/-100mA instead of 0-100mA. This means
+that the power on ramp needs to take the lens from the midpoint, and
+power off return it there. It also changes the default position for
+the module.

+Subject: [PATCH] media: dw9807-vcm: Add regulator support to the driver
+
+Uses the regulator notifier framework so that the current
+focus position will be restored whenever any user of the
+regulator powers it up. This means that should the VCM
+and sensor share a common regulator then starting the sensor
+will automatically restore the default position. If they
+have independent regulators then it will behave be powered
+up when the VCM subdev is opened.

+
+The power up/down sequence is already ramped. Extend this to
+the first user movement as well, as this will generally avoid
+the "tick" noises due to rapid movements and overshooting.
+Subsequent movements are generally smaller and so don't cause
+issues.

++description: |-
++  The Sony IMX708 is a 1/2.3-inch CMOS active pixel digital image sensor
++  with an active array size of 4608H x 2592V. It is programmable through
++  I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
++  Image data is sent through MIPI CSI-2, which is configured as either 2 or
++  4 data lanes.

+Subject: [PATCH] media/i2c: Add a driver for the Sony IMX708 image sensor
+
+The imx708 is a 12MP MIPI sensor with a 16:9 aspect ratio, here using
+two CSI-2 lanes. It is a "quad Bayer" sensor with all 3 modes offering
+10-bit output:
+
+12MP: 4608x2592 up to 14.35fps (full FoV)
+1080p: 2304x1296 up to 56.02fps (full FoV)
+720p: 1536x864 up to 120.12fps (cropped)
+
+This imx708 sensor driver is based heavily on the imx477 driver and
+has been tested on the Raspberry Pi platform using libcamera.

+Subject: [PATCH] net: phy: broadcom: Make LEDs 3+4 shadow LEDs 1+2
+
+CM4 uses BCM54210PE, which supports 2 additional LEDs, choosing LED3
+for the amber LED because it shows activity by default (LED4 is not
+connected). However, this makes it uncontrollable by the eth_led<n>
+dtparams which target LEDs 1+2.
+
+Solve the problem by making LEDs 3+4 mirror LEDs 1+2 (which is much
+simpler than adding baseboard-specific overrides, but comes with a
+risk of making one of the LEDs redundant).
+
+See: https://github.com/raspberrypi/linux/issues/5289

+Subject: [PATCH] drm/vc4: hdmi: Add property to allow manual config of RGB or
+ YCbCr
+
+Add a custom property "Output format" that allows the overriding
+of the default colourspace choice in the way that the old
+firmware hdmi_pixel_encoding property did. If the chosen format is not
+supported, then it will still drop back to the older behaviour.
+
+This won't be acceptable to upstream, but it adds back the missing
+functionality of hdmi_pixel_encoding.

+Subject: [PATCH] bcm2835-mmc: Honor return value of mmc_of_parse()
+
+bcm2835_mmc_probe() ignores errors returned by mmc_of_parse() and in
+particular ignores -EPROBE_DEFER, which may be returned if the power
+sequencing driver configured in the devicetree is compiled as a module.
+
+The user-visible result is that access to the SDIO device fails because
+its power sequencing requirements have not been observed.  Fix it.

+Subject: [PATCH] drm/vc4: hvs: Defer dlist slots deallocation
+
+During normal operations, the cursor position update is done through an
+asynchronous plane update, which on the vc4 driver basically just
+modifies the right dlist word to move the plane to the new coordinates.
+
+However, when we have the overscan margins setup, we fall back to a
+regular commit when we are next to the edges. And since that commit
+happens to be on a cursor plane, it's considered a legacy cursor update
+by KMS.
+
+The main difference it makes is that it won't wait for its completion
+(ie, next vblank) before returning. This means if we have multiple
+commits happening in rapid succession, we can have several of them
+happening before the next vblank.
+
+In parallel, our dlist allocation is tied to a CRTC state, and each time
+we do a commit we end up with a new CRTC state, with the previous one
+being freed. This means that we free our previous dlist entry (but don't
+clear it though) every time a new one is being committed.
+
+Now, if we were to have two commits happening before the next vblank, we
+could end up freeing reusing the same dlist entries before the next
+vblank.
+
+Indeed, we would start from an initial state taking, for example, the
+dlist entries 10 to 20, then start a commit taking the entries 20 to 30
+and setting the dlist pointer to 20, and freeing the dlist entries 10 to
+20. However, since we haven't reach vblank yet, the HVS is still using
+the entries 10 to 20.
+
+If we were to make a new commit now, chances are the allocator are going
+to give the 10 to 20 entries back, and we would change their content to
+match the new state. If vblank hasn't happened yet, we just corrupted
+the active dlist entries.
+
+A first attempt to solve this was made by creating an intermediate dlist
+buffer to store the current (ie, as of the last commit) dlist content,
+that we would update each time the HVS is done with a frame. However, if
+the interrupt handler missed the vblank window, we would end up copying
+our intermediate dlist to the hardware one during the composition,
+essentially creating the same issue.
+
+Since making sure that our interrupt handler runs within a fixed,
+constrained, time window would require to make Linux a real-time kernel,
+this seems a bit out of scope.
+
+Instead, we can work around our original issue by keeping the dlist
+slots allocation longer. That way, we won't reuse a dlist slot while
+it's still in flight. In order to achieve this, instead of freeing the
+dlist slot when its associated CRTC state is destroyed, we'll queue it
+in a list.
+
+A naive implementation would free the buffers in that queue when we get
+our end of frame interrupt. However, there's still a race since, just
+like in the shadow dlist case, we don't control when the handler for
+that interrupt is going to run. Thus, we can end up with a commit adding
+an old dlist allocation to our queue during the window between our
+actual interrupt and when our handler will run. And since that buffer is
+still being used for the composition of the current frame, we can't free
+it right away, exposing us to the original bug.
+
+Fortunately for us, the hardware provides a frame counter that is
+increased each time the first line of a frame is being generated.
+Associating the frame counter the image is supposed to go away to the
+allocation, and then only deallocate buffers that have a counter below
+or equal to the one we see when the deallocation code should prevent the
+above race from occuring.

+Subject: [PATCH] vc4/hdmi: Always enable GCP with AVMUTE cleared
+
+See: https://forum.libreelec.tv/thread/24780-le-10-0-1-rpi4-no-picture-after-update-from-le-10-0-0
+
+Issue is some displays go blank at the point of firmware to kms handover.
+Plugging/unplugging hdmi cable, power cycling display, or switching standby off/on
+typically resolve this case.
+
+Finally managed to find a display that suffers from this, and track down the issue.
+
+The firmware uses AVMUTE in normal operation. It will set AVMUTE before disabling hdmi
+clocks and phy. It will clear AVMUTE after clocks and phy are set up for a new hdmi mode.
+
+But with the hdmi handover from firmware to kms, AVMUTE will be set by firmware.
+
+kms driver typically has no GCP packet (except for deep colour modes).
+The spec isn't clear on whether to consider the AVMUTE as continuing indefinitely
+in the absense of a GCP packet, or to consider that state to have ended.
+
+Most displays behave as we want, but there are a number (from mutiple manufacturers)
+which need to see AVMUTE cleared before displaying a picture.
+
+Lets just always enable GCP packet with AVMUTE cleared. That resolves the issue on
+problematic displays.
+
+From HDMI 1.4 spec:
+A CD field of zero (Color Depth not indicated) shall be used whenever the Sink does
+not indicate support for Deep Color. This value may also be used in Deep Color mode
+to transmit a GCP indicating only non-Deep Color information (e.g. AVMUTE).
+
+So use CD=0 where we were previously not enabling a GCP.

+Subject: [PATCH] kunit: Provide a static key to check if KUnit is actively
+ running tests
+
+KUnit does a few expensive things when enabled. This hasn't been a
+problem because KUnit was only enabled on test kernels, but with a few
+people enabling (but not _using_) KUnit on production systems, we need a
+runtime way of handling this.
+
+Provide a 'kunit_running' static key (defaulting to false), which allows
+us to hide any KUnit code behind a static branch. This should reduce the
+performance impact (on other code) of having KUnit enabled to a single
+NOP when no tests are running.
+
+Note that, while it looks unintuitive, tests always run entirely within
+__kunit_test_suites_init(), so it's safe to decrement the static key at
+the end of this function, rather than in __kunit_test_suites_exit(),
+which is only there to clean up results in debugfs.

+Subject: [PATCH] kunit: Use the static key when retrieving the current test
+
+In order to detect if a KUnit test is running, and to access its
+context, the 'kunit_test' member of the current task_struct is used.
+Usually, this is accessed directly or via the kunit_fail_current_task()
+function.
+
+In order to speed up the case where no test is running, add a wrapper,
+kunit_get_current_test(), which uses the static key to fail early.
+Equally, Speed up kunit_fail_current_test() by using the static key.
+
+This should make it convenient for code to call this
+unconditionally in fakes or error paths, without worrying that this will
+slow the code down significantly.
+
+If CONFIG_KUNIT=n (or m), this compiles away to nothing. If
+CONFIG_KUNIT=y, it will compile down to a NOP (on most architectures) if
+no KUnit test is currently running.
+
+Note that kunit_get_current_test() does not work if KUnit is built as a
+module. This mirrors the existing restriction on kunit_fail_current_test().
+
+Note that the definition of kunit_fail_current_test() still wraps an
+empty, inline function if KUnit is not built-in. This is to ensure that
+the printf format string __attribute__ will still work.
+
+Also update the documentation to suggest users use the new
+kunit_get_current_test() function, update the example, and to describe
+the behaviour when KUnit is disabled better.

+Subject: [PATCH] drm/vc4: hvs: Destroy dlist allocations immediately when
+ running a test
+
+When running a kunit test, the driver runs with a mock device. As such,
+any attempt to read or write to a hardware register will fail the
+current test immediately.
+
+The dlist allocation management recently introduced will read the
+current frame count from the HVS to defer its destruction until a
+subsequent frame has been output. This obviously involves a register
+read that fails the Kunit tests.
+
+Change the destruction deferral function to destroy the allocation
+immediately if we run under kunit. This is essentially harmless since
+the main reason for that deferall is to prevent any access to the
+hardware dlist while a frame described by that list is rendered. On our
+mock driver, we have neither a hardware dlist nor a rendering, so it
+doesn't matter.

+Subject: [PATCH] ARM: dts: Set the LED default-state to "off"
+
+The default-state property for an LED determines the state of the LED
+when its trigger is set to "none". Many users expect that specifying a
+trigger of "none" means that the LED will be off, and there is a logic
+to that assumption, but the current default of "keep" makes the
+assumption false.
+
+Given that no Pi models have a default-trigger of "none", changing the
+default-state should have no visible impact for most people, but doing
+so will permit a more obvious and more consistent way of turning off
+the LEDs.
+
+Note that 6.2 included an upstream DT reorganisation that required some
+downstream changes, and while doing that I changed the default states.
+This commit brings rpi-6.1.y into line with rpi-6.2.y.
+

+Subject: [PATCH] drm/vc4_plane: Add support for YUV444 formats
+
+Support displaying DRM_FORMAT_YUV444 and DRM_FORMAT_YVU444 formats.
+Tested with kmstest and kodi. e.g.
+
+kmstest -r 1920x1080@60 -f 400x300-YU24
+
+Note: without the shift of width, only half the chroma is fetched,
+resulting in correct left half of image and corrupt colours on right half.
+
+The increase in width shouldn't affect fetching of Y data,
+as the hardware will clamp at dest width.

+Subject: [PATCH] drm/vc4: Calculate bpc based on max_requested_bpc
+
+This aligns vc4 with Intel, AMD and Synopsis drivers and fixes max bpc
+connector property not working as expected on monitors with YCbCr 4:2:2
+support but not deep color support.
+
+max_bpc in connector state is clamped at max_bpc from display info and
+the latter only takes deep color modes into account so it will always
+be 8, even if the display can do 4:2:2 12-bit output.

+Subject: [PATCH] vc04_services: bcm2835_codec: Ignore READ_ONLY ctrls in
+ s_ctrl
+
+In adding the MPEG2/MPEG4/H264 level and profile controls to
+the decoder, they weren't declared as read-only, nor handlers
+added to bcm2835_codec_s_ctrl. That resulted in an error message
+"Invalid control" being logged every time v4l2_ctrl_handler_setup
+was called from bcm2835_codec_create_component.
+
+Define those controls as read only, and exit early from s_ctrl
+on read only controls.
+
+Fixes: "media: bcm2835-v4l2-codec: Add profile & level ctrls to decode"
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

+Date: Tue, 1 Feb 2022 15:27:01 +0000
+Subject: [PATCH] drm/panel/panel-sitronix-st7701: Support SPI config and RGB
+ data
+
+The ST7701 supports numerous different interface mechanisms for
+MIPI DSI, RGB, or SPI. The driver was only implementing DSI input,
+so add RGB parallel input with SPI configuration.

+Subject: [PATCH] ARM: dts: Standardise on the upstream LED names
+
+Historically, downstream Pi DTS files have named the LEDs led0 and (if
+present) led1, while upstream have used the more meaningful "ACT" and
+"PWR". As part of a closer alignment with upstream, make the LED names
+match.

+Subject: [PATCH] ARM: dts: bcm2711-rpi-400: Restore the ACT LED
+
+Pi 400 doesn't have an ACT LED, only a green PWR LED, but a user may
+wish to remap the ACT functionality to a GPIO on the 40-pin header.
+Restore the ACT LED declaration, but leave it disabled in order to
+prevent a GPIO being claimed until either the act_led_gpio dtparam
+or the act-led overlay is used.

+Subject: [PATCH] media: i2c: imx219: make HBLANK r/w to allow longer exposures
+
+The HBLANK control was read-only, and always configured such
+that the sensor HTS register was 3448. This limited the maximum
+exposure time that could be achieved to around 1.26 secs.
+
+Make HBLANK read/write so that the line time can be extended,
+and thereby allow longer exposures (and slower frame rates).
+Retain the overall HTS setting when changing modes rather than
+resetting it to a default.

+Subject: [PATCH] media: imx219: Advertise embedded data node on media pad 1
+
+This commit updates the imx219 driver to adverise support for embedded
+data streams.  This can then be used by the bcm2835-unicam driver, which
+has recently been updated to expose the embedded data stream to
+userland.
+
+The imx219 sensor subdevice overloads the media pad to differentiate
+between image stream (pad 0) and embedded data stream (pad 1) when
+performing the v4l2_subdev_pad_ops functions.

+Subject: [PATCH] drm/vc4: drop unnecessary and harmful HDMI RGB format check
+
+RGB is a mandatory format for all DVI and HDMI monitors so there's
+no need to check for presence of the DRM_COLOR_FORMAT_RGB444 bit in
+color_formats.
+
+More importantly this checks breaks working around EDID issues with
+eg video=HDMI-A-1:1024x768D or drm.edid_firmware=edid/1024x768.bin
+as the RGB444 bit is only set when a valid EDID with digital bit set in
+the input byte is present - which isn't the case when no EDID can be
+read from the display device at all or with the in-built kernel EDIDs,
+which mimic analog (VGA) displays without the digital bit set.
+
+So drop the check, if we output video on the HDMI connector we can
+assume that the display can accept 8bit RGB.

+-description: |-
+-  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
+-  sensor with square pixel array and 1.58 M effective pixels. This chip
+-  features a global shutter with variable charge-integration time. It is
+-  programmable through I2C and 4-wire interfaces. The sensor output is
+-  available via CSI-2 serial data output (1 Lane).

++description: |-
++  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
++  sensor with square pixel array and 1.58 M effective pixels. This chip
++  features a global shutter with variable charge-integration time. It is
++  programmable through I2C and 4-wire interfaces. The sensor output is
++  available via CSI-2 serial data output (1 Lane).
++
++properties:
++  compatible:
++    enum:
++      - sony,imx296
++      - sony,imx296ll
++      - sony,imx296lq
++    description:
++      The IMX296 sensor exists in two different models, a colour variant
++      (IMX296LQ) and a monochrome variant (IMX296LL). The device exposes the
++      model through registers, allowing for auto-detection with a common
++      "sony,imx296" compatible string. However, some camera modules disable the
++      ability to read the sensor model register, which disables this feature.
++      In those cases, the exact model needs to be specified as "sony,imx296ll"
++      or "sony,imx296lq".

+Subject: [PATCH] media: i2c: IMX296 camera sensor driver
+
+The IMX296LLR is a monochrome 1.60MP CMOS sensor from Sony. The driver
+supports cropping and binning (but not both at the same time due to
+hardware limitations) and exposure, gain, vertical blanking and test
+pattern controls.
+
+Preliminary support is also included for the color IMX296LQR sensor.

+Subject: [PATCH] media: i2c: imx296: Set a 1 frame gain delay
+
+Set the gain delay to 1 frame in the sensor. This avoids any race
+condition or ambiguity over when the setting is applied through
+userland.

+Subject: [PATCH] media: i2c: imx296: Add horizontal/vertical flip support
+
+Add support for setting horizontal and/or vertial flips in the IMX296
+sensor through the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls.
+
+Add a new helper function to return the media bus format code that
+depends on the sensor flips.
+
+Grab the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls on stream on, and
+release on stream off to ensure flips cannot be changed while the sensor
+is streaming.

+ requested
+
+Busy spinning after halt is dumb
+We've previously applied this patch to arch/arm
+but it is currenltly missing in arch/arm64
+
+Pi4 after "sudo halt" uses 520mA
+Pi4 after "sudo shutdown now" uses 310mA
+
+Make them both use the lower powered option

+ with long exposure
+
+Setting V4L2_CID_WIDE_DYNAMIC_RANGE was causing the long exposure
+shift count to be reset, which is incorrect if the user has already
+changed the frame length to cause it to have a non-zero value.
+
+Because it only updates control ranges and doesn't set any registers,
+the control can also be applied when the sensor is not powered on.

+Subject: [PATCH] rpisense-fb: Flush any deferred updates on release
+
+Since [1], writing to the Sense HAT framebuffer and immediately closing
+the file descriptor is likely to have no effect. This is because the
+framebuffer deferred IO framework is now careful to cancel pending
+updates.
+
+To retain the old behaviour, add an fb_release method that flushes the
+updates instead.

+
+FFmpeg insists on trying to set V4L2_CID_MPEG_VIDEO_B_FRAMES to
+0, and generates an error should it fail.
+As our encoder doesn't support B frames, add a stub handler for
+it to silence FFmpeg.

+Subject: [PATCH] staging: bcm2835-codec: Add support for
+ V4L2_CID_MPEG_VIDEO_GOP_SIZE
+
+For H264, V4L2_CID_MPEG_VIDEO_H264_I_PERIOD is meant to be the intra
+I-frame period, whilst V4L2_CID_MPEG_VIDEO_GOP_SIZE is the intra IDR
+frame period.
+The firmware encoder doesn't produce I-frames that aren't IDR as well,
+therefore V4L2_CID_MPEG_VIDEO_GOP_SIZE is technically the correct
+control, however users may have adopted V4L2_CID_MPEG_VIDEO_H264_I_PERIOD.
+
+Add support for V4L2_CID_MPEG_VIDEO_GOP_SIZE controlling the encoder,
+and have VIDIOC_S_CTRL for V4L2_CID_MPEG_VIDEO_H264_I_PERIOD update
+the value for V4L2_CID_MPEG_VIDEO_GOP_SIZE (the reverse is not
+implemented).

+Subject: [PATCH] dtoverlays: Add inverted override property to ssd1306-spi
+
+The new ssd130x DRM driver supports both SSD1306 I2C and SPI panels and is
+compatible with the ssd1307fb driver bindings. So the "solomon,com-invdir"
+DT property (to invert the COM pin scan dir) can also be used for SPI now.
+
+This allows to configure panels whose scan direction needs to be inverted.

+Subject: [PATCH] media: i2c: imx290: Use device lock for the control handler
+
+Upstream commit 08878cbc0cbf.
+
+The link frequency and pixel rate controls are set without holding the
+control handler lock, resulting in kernel warnings. As the value of
+those controls depend on the format, the simplest fix is to use the
+device lock for the control handler.

+
+Upstream commit 2548df538cdd.
+
+Use ARRAY_SIZE(imx290->supplies) for code that needs the size of the
+array, instead of relying on the IMX290_NUM_SUPPLIES. The result is less
+error-prone as it ties the size to the array.

+Subject: [PATCH] media: i2c: imx290: Drop imx290_write_buffered_reg()
+
+Upstream commit b817888a0c50.
+
+The imx290_write_buffered_reg() function wraps a register write with
+register hold, to enable changing multiple registers synchronously. It
+is used for the gain only, which is an 8-bit register, defeating its
+purpose.
+
+The feature is useful, but should be implemented differently. Drop the
+function for now, to prepare for a rework of register access.

+
+Upstream commit 72825bc6f7f5.
+
+The HMAX value specifies the total line length in pixels. It's thus more
+readable in decimal than hexadecimal. Fix it.

+Subject: [PATCH] media: i2c: imx290: Support variable-sized registers
+
+Upstream commit e70abe881463.
+
+The IMX290 has registers of different sizes. To simplify the code,
+handle this in the read/write functions instead of in the callers by
+encoding the register size in the symbolic name macros. All registers
+are defined as 8-bit for now, a subsequent change will move to larger
+registers where applicable.

+Subject: [PATCH] media: i2c: imx290: Simplify error handling when writing
+ registers
+
+Upstream commit e611f3dac54c.
+
+Error handling for register writes requires checking the error status of
+every single write. This makes the code complex, or incorrect when the
+checks are omitted. Simplify this by passing a pointer to an error code
+to the imx290_write_reg() function, which allows writing multiple
+registers in a row and only checking for errors at the end.
+
+While at it, rename imx290_write_reg() to imx290_write() as there's
+nothing else than registers to write, and rename imx290_read_reg()
+accordingly.

+From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
+Date: Mon, 17 Oct 2022 11:35:45 +0300
+Subject: [PATCH] media: i2c: imx290: Define more register macros
+
+Upstream commit 79d99ae8a77e.
+
+Define macros for all registers programmed by the driver for which
+documentation is available to increase readability. This starts making
+use of 16-bit registers in the register arrays, so the value field has
+to be increased to 32 bits.

+Subject: [PATCH] media: i2c: imx290: Fix max gain value
+
+Upstream commit 6d7a87f2d3a6.
+
+The gain is expressed in multiple of 0.3dB, as a value between 0.0dB
+and 72.0dB. Gains between 0.0dB and 30.0dB (included) apply analog gain
+only, higher gains from 30.3dB to 72dB apply additional digital gain.
+
+The maximum gain value is erroneously set to 72. Increase it to 100 to
+cover the whole analog gain range. Support for digital gain can be added
+separately if needed.
+
+The IMX327 and IMX462 are largely compatible with the IMX290, but have
+an analog gain range of 0.0dB to 29.4dB and 42dB of digital gain. When
+support for those sensors gets added to the driver, the gain control
+should be adjusted accordingly.

+Subject: [PATCH] media: i2c: imx290: Replace GAIN control with ANALOGUE_GAIN
+
+Upstream commit 3dd10515a1d9
+
+The IMX290 gain register controls the analogue gain. Replace the
+V4L2_CID_GAIN control with V4L2_CID_ANALOGUE_GAIN.

+Subject: [PATCH] media: i2c: imx290: Group functions in sections
+
+Upstream commit cb7e1c8dbe60
+
+Move functions around to group them in logical sections, in order to
+improve readability. As a result, the IMX290_NUM_SUPPLIES macro has to
+be changed. No other code change is included, only moves.

+Subject: [PATCH] media: i2c: imx290: Factor out subdev init and cleanup to
+ functions
+
+Upstream commit dfb704da8300.
+
+The probe() function is large. Make it more readable by factoring the
+subdev initialization code out. While at it, rename the error labels as
+the "free_" prefix isn't accurate.
+
+No functional change intended.

+Subject: [PATCH] media: i2c: imx290: Access link_freq_index directly
+
+Upstream commit 70bbf56aa82c
+
+The imx290_get_link_freq_index() function hides the fact that it relies
+on the imx290 current_mode field, which obfuscates the code instead of
+making it more readable. Inline it in the callers, and use the mode
+pointer we already have in imx290_ctrl_update() instead of using the
+current_mode field.

+ imx290_calc_pixel_rate()
+
+Upstream commit 31b54a422b3f
+
+Avoid accessing the imx290 current_format and current_mode fields in
+imx290_calc_pixel_rate() to prepare for the removal of those fields.
+Among the two callers of the function, imx290_ctrl_update() has an
+explicit mode pointer already, and we can also give it a format pointer.
+Use those explicitly.
+
+While at it, inline the imx290_get_link_freq() function in
+imx290_calc_pixel_rate() as it is only called there.

+
+Upstream commit 693b5cb598cc
+
+The hblank, vblank, pixel rate and link frequency values and limits are
+currently computed when creating controls, in imx290_ctrl_init(), and
+updated in imx290_ctrl_update(). This duplicates the logic in different
+places. Simplify the code by setting the control values and limits to
+hardcoded values when creating the controls, and call
+imx290_ctrl_update() to then update them.

+ function
+
+Upstream commit ee4ce8936693
+
+The black level programmed in the BLKLEVEL register depends on the
+output format. The black level value computation is currently performed
+in imx290_set_ctrl(), in addition to having different black level values
+in the output-specific register value tables. Move it to a separate
+function to simplify the imx290_set_ctrl() code.

+Subject: [PATCH] media: i2c: imx290: Use V4L2 subdev active state
+
+Upstream commit a2514b9a634a
+
+Use the V4L2 subdev active state API to store the active format. This
+simplifies the driver not only by dropping the imx290 current_format
+field, but it also allows dropping the imx290 lock, replaced with the
+state lock.
+
+The lock check in imx290_ctrl_update() can be dropped as
+imx290_set_fmt() can't be called anywmore with which set to ACTIVE
+before controls are initialized.

+Subject: [PATCH] media: i2c: imx290: Rename, extend and expand usage of
+ imx290_pixfmt
+
+Upstream commit 10591fe63691
+
+The imx290_pixfmt structure contains information about formats,
+currently limited to the bpp value. Extend it with the register settings
+for each format, and rename it to imx290_format_info to make its purpose
+clearer. Add a function named imx290_format_info() to look up format
+info for a media bus code, and use it through the code. This allows
+dropping the imx290 bpp field as the value is now looked up dynamically.
+
+The error handling in imx290_setup_format() can also be dropped, as the
+format is guaranteed by imx290_set_fmt() to be valid.

+Subject: [PATCH] media: i2c: imx290: Use runtime PM autosuspend
+
+Upstream commit a8c3e0c1bf1e
+
+Use runtime PM autosuspend to avoid powering off the sensor during fast
+stop-reconfigure-restart cycles. This also fixes runtime PM handling in
+the probe function that didn't suspend the device, effectively leaving
+it resumed forever.
+
+While at it, improve documentation of power management in probe() and
+remove().

+Subject: [PATCH] media: i2c: imx290: Initialize runtime PM before subdev
+
+Upstream commit 02852c01f654
+
+Initializing the subdev before runtime PM means that no subdev
+initialization can interact with the runtime PM framework. This can be
+problematic when modifying controls, as the .s_ctrl() handler commonly
+calls pm_runtime_get_if_in_use(). These code paths are not trivial,
+making the driver fragile and possibly causing subtle bugs.
+
+To make the subdev initialization more robust, initialize runtime PM
+first.

+There's no need to check for an incorrect number of data lanes in

+the check.
+
+The PHY_LANE_NUM and CSI_LANE_MODE registers are programmed with a value

+
+Upstream commit a96dfea1df25
+
+Convert the Sony IMX290 DT binding from text to YAML. Add Manivannan as
+a maintainer given that he is listed in MAINTAINERS for the file, as
+volunteering myself.
+
+The name of the input clock, "xclk", is wrong as the hardware manual
+names it INCK. As the device has a single clock, the name could be
+omitted, but that would require a corresponding change to the driver and
+is thus a candidate for further patches.

+Subject: [PATCH] media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s
+
+Should be upstream commit 4381df0c756f
+
+The datasheet lists the link frequency changes between
+1080p and 720p modes. This is correct that the link frequency
+changes as measured on an oscilloscope.
+
+Link frequency is not necessarily the same as pixel rate.
+
+The datasheet gives standard configurations for 1080p and 720p
+modes at a number of frame rates.
+Looking at the 1080p mode it gives:
+HMAX = 0x898 = 2200
+VMAX = 0x465 = 1125
+2200 * 1125 * 60fps = 148.5MPix/s
+
+Looking at the 720p mode it gives:
+HMAX = 0xce4 = 3300
+VMAX = 0x2ee = 750
+3300 * 750 * 60fps = 148.5Mpix/s
+
+This driver currently scales the pixel rate proportionally to the
+link frequency, however the above shows that this is not the
+correct thing to do, and currently all frame rate and exposure
+calculations give incorrect results.
+
+Correctly report the pixel rate as being 148.5MPix/s under any
+mode.

+Subject: [PATCH] media: i2c: imx290: Support 60fps in 2 lane operation
+
+Should be upstream commit 7d4f22ba99cc
+
+Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes"
+added support for running in two lane mode (instead of 4), but
+without changing the link frequency that resulted in a max of 30fps.
+
+Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
+and pixel rate" then doubled the link frequency when in 2 lane mode,
+but didn't undo the correction for running at only 30fps, just extending
+horizontal blanking instead.
+
+Remove the 30fps limit on 2 lane by correcting the register config
+in accordance with the datasheet for 60fps operation over 2 lanes.

+Subject: [PATCH] media: i2c: imx290: Convert V4L2_CID_VBLANK to read/write
+
+Should be upstream commit 97792a11021b
+
+The driver exposed V4L2_CID_VBLANK as a read only control to allow
+for exposure calculations and determination of the frame rate.
+
+Convert to a read/write control so that the frame rate can be
+controlled.
+V4L2_CID_VBLANK also sets the limits for the exposure control,
+therefore exposure ranges have to be updated when vblank changes
+(either via s_ctrl, or via changing mode).

+Subject: [PATCH] media: i2c: imx290: VMAX is mode dependent
+
+Should be upstream commit b3aa351ea88a
+
+The default VMAX for 60fps in 720p mode is 750 according to the
+datasheet, however the driver always left it at 1125 thereby stopping
+60fps being achieved.
+
+Make VMAX (and therefore V4L2_CID_VBLANK) mode dependent so that 720p60
+can be achieved.

+Date: Thu, 16 Feb 2023 00:30:01 +0200
+Subject: [PATCH] media: i2c: imx290: Add support for 74.25MHz external clock
+
+Should be upstream commit b8b86dfe1aee
+
+The sensor supports either a 37.125 or 74.25MHz external, but
+the driver only supported 37.125MHz.
+
+Add the relevant register configuration for either clock
+frequency option.

+Subject: [PATCH] media: i2c: imx290: Add support for H & V Flips
+
+Should be upstream commit 42765b80f8c6
+
+The sensor supports H & V flips, so add the relevant hooks for
+V4L2_CID_HFLIP and V4L2_CID_VFLIP to configure them.
+
+Note that the Bayer order is maintained as the readout area
+shifts by 1 pixel in the appropriate direction (note the
+comment about the top margin being 8 pixels whilst the bottom
+margin is 9). The V4L2_SEL_TGT_CROP region is therefore
+adjusted appropriately.

+
+Should be upstream commit 3c3f66b8125a
+
+Both sensors are quite similar. Their specs only differ regarding LVDS
+and parallel output but are identical regarding MIPI-CSI-2 interface.
+But they use a different init setting of hard-coded values, taken from
+the datasheet.

+Subject: [PATCH] fbdev: Don't cancel deferred work if pagelist empty
+
+Since [1], the fbdev deferred IO framework is careful to cancel
+pending updates on close to prevent dirty pages being accessed after
+they may have been reused. However, this is not necessary in the case
+that the pagelist is empty, and drivers that don't make use of the
+pagelist may have wanted updates cancelled for no good reason.
+
+Avoid penalising fbdev drivers that don't make use of the pagelist by
+making the cancelling of deferred IO on close conditional on there
+being a non-empty pagelist.
+

+This is a downstream feature that allows usbhid to restrict polling

+Subject: [PATCH] media: bcm2835-unicam: Start and stop media_pipeline with
+ same node
+
+media_pipeline_start and media_pipeline_stop now validate that
+the pipeline is being started and stopped with the same pipe
+and pad handles.
+When running with embedded metadata (eg imx477 and imx708), the
+start typically happens from the metadata pad, whilst stop is
+always from the image pad.
+
+Always pass the image pad to media_pipeline_start to ensure
+that the calls are balanced.

+Subject: [PATCH] fixup! gpio-fsm: Avoid truncation of delay jiffies
+
+The kernel's time unit of jiffies should be stored as an unsigned long
+value. Storing it as an unsigned int, as gpio-fsm did, leads to
+truncation and malfunction when the kernel is built for a 64-bit
+platform.

+
+This reverts commit 947ba6e85ea973b53e2f8d6860b191c0257e04fb.
+
+Since [1], the clock driver has automatically rounded up the
+UART clock frequency, so this patch is no longer needed.

+ 640x480 mode
+
+The 640x480 mode uses a special binning mode for high framerate operation where
+the pixel rate is effectively doubled. Account for this when setting up the
+pixel clock rate, and applying the vblank and exposure controls.

+Subject: [PATCH] arm/boot/dts/overlays/mipi-dbi-spi: fix default brightness
+ (#5442)
+
+There is an off-by-one error in the default brightness for the PWM backlight
+in the MIPI DBI SPI overlay that produces the following message in the
+kernel logs:
+
+    pwm-backlight backlight_pwm: invalid default brightness level: 16, using 15
+
+The value is 0-based, so the max brightness is 15, not 16.

+Subject: [PATCH] hwmon: emc2305: Change OF properties pwm-min & pwm-max to u8
+
+There is no DT binding for emc2305 as mainline are still
+discussing how to do a generic fan binding.
+The 5.15 driver was reading the "emc2305," properties
+"cooling-levels", "pwm-max", "pwm-min", and "pwm-channel" as u8.
+The overlay was writing them as u16 (;) so it was working.
+
+The 6.1 driver was reading as u32, which failed as there is
+insufficient data.
+
+As this is all downstream only, revert to u8 to match 5.15.

+Subject: [PATCH] serial: 8250: Add NOMSI bug for bcm2835aux
+
+The BCM2835 mini-UART has no modem status interrupt, causing all
+transmission to stop, never to use, if a speed change ever happens
+while the CTS signal is high.
+
+Add a simple polling mechanism in order to allow recovery in that
+situation.

+Subject: [PATCH] pinctrl: bcm2835: Workaround for edge IRQ loss
+
+It has been observed that edge events can be lost when GPIO edges occur
+close to each other. Investigation suggests this is due to a hardware
+bug, although no mechanism has been identified.
+
+Work around the event loss by moving the IRQ acknowledgement into the
+main ISR, adding missing events by explicit level-change detection.
+

+Subject: [PATCH] drm/v3d: New debugfs end-points to query GPU usage stats.
+
+Two new debugfs interfaces are implemented:
+
+- gpu_usage: exposes the total runtime since boot of each
+of the 5 scheduling queues available at V3D (BIN, RENDER,
+CSD, TFU, CACHE_CLEAN). So if the interface is queried at
+two different points of time the usage percentage of each
+of the queues can be calculated.
+
+- gpu_pid_usage: exposes the same information but to the
+level of detail of each process using the V3D driver. The
+runtime for process using the driver is stored. So the
+percentages of usage by PID can be calculated with
+measures at different timestamps.
+
+The storage of gpu_pid_usage stats is only done if
+the debugfs interface is polled during the last 70 seconds.
+If a process does not submit a GPU job during last 70
+seconds its stats will also be purged.

+Subject: [PATCH] bcm2835-dma: Derive slave DMA addresses correctly
+
+Slave addresses for DMA are meant to be supplied as physical addresses
+(contrary to what struct snd_dmaengine_dai_dma_data does). It is up to
+the DMA controller driver to perform the translation based on its own
+view of the world, as described in Device Tree.
+
+Now that the Pi Device Trees have the correct peripheral mappings,
+replace the hacky address munging with phys_to_dma().

+Subject: [PATCH] dmaengine: bcm2835: Fix position reporting for 40 bits
+ channels
+
+For 40 bits channels, the position is reported by reading the upper byte
+in the SRCI/DESTI registers. However the driver adds that upper byte
+with an 8-bits left shift, while it should be 32.

+Subject: [PATCH] dmaengine: bcm2835: Fix descriptors usage for 40-bits
+ channels
+
+The bcm2835_dma_create_cb_chain() function is in charge of building up
+the descriptors chain for a given transfer.
+
+It was initially supporting only the BCM2835-style DMA controller, and
+was later expanded to support controllers with 40-bits channels that use
+a different descriptor layout.
+
+However, some part of the function only use the old style descriptor,
+even when building a chain of new-style descriptors, resulting in weird
+bugs.

+
+The sequence we were doing was not safe.
+
+Clearing CS meant BCM2835_DMA_WAIT_FOR_WRITES was cleared
+and so polling BCM2835_DMA_WAITING_FOR_WRITES has no benefit
+
+Broadcom have provided a recommended sequence to abort
+a dma lite channel, so switch to that.

+Subject: [PATCH] bcm2711-rpi-ds: Switch to dma40 channel for hdmi audio
+
+Also tweak the flags:
+Remove NO_WAIT_RESP (27)
+Add BURST_LENGTH (30)
+
+The AXI path from DMA controller to HDMI audio fifo
+is long, and may have considerable delay.
+
+When using DMA without waiting for responses it is
+very easy to overfill the fifo as when the fifo
+removes DREQ there may be large numbers of writes
+in flight.
+
+This means the DREQ fifo threshold must be set low
+enough to accommodate the maximum number of in flight
+writes (unknown by something like 24),
+which means the 32 element fifo only requests data
+when it contains fewer than 8 entries, making it
+susceptable to underflow.
+
+If we wait for write responses we can set the DREQ
+fifo threshold much higher as there are a controlled
+number of writes in flight.
+
+However the overall bandwidth is reduced by setting
+this, so also enable a burstsize of 4 to improve
+bandwidth.

+Subject: [PATCH] ARM: dts: bcm2711-rpi: Set a 1GB ZONE_DMA limit
+
+The arm64 initialisation uses the physical address reachable by all
+DMA controllers to set the size of ZONE_DMA. This fails on BCM2711
+with the current dts files because the declaration of the I/O space
+fools it into thinking the legacy 30-bit DMA channels can see most
+of the 32-bit space.
+
+Take advantage of the simple nature of the implementation by adding
+a node with a restricted dma-ranges property solely so to act as the
+limiting factor in the calculation.

+Subject: [PATCH] pps: Compatibility hack should be X86-specific
+
+As of [1], using PPS_FETCH on a 64-bit ARM kernel with a 32-bit userland
+is broken, returning a timeout. This is because the requested 4-byte
+alignment for struct pps_ktime_compat (illegal on arm64) results in the
+timeout flags field being uninitialised.
+
+Make the hack specific to X86_64 builds with CONFIG_COMPAT defined.

+Subject: [PATCH] bcm2835-dma: Fixes for dma_abort
+
+There is a problem with the current abort scheme
+when dma is blocked on a DREQ which prevents halting.
+
+This is triggered by SPI driver which aborts dma
+in this state and so leads to a halt timeout.
+
+Discussion with Broadcom suggests the sequence:
+
+CS.ACTIVE=0
+while (CS.OUTSTANDING_TRANSACTIONS == 0)
+  wait()
+DEBUG.RESET=1
+
+should be safe on a dma40 channel.
+
+Unfortunately the non-dma40 channels don't have
+OUTSTANDING_TRANSACTIONS, so we need a more
+complicated scheme.
+
+We attempt to abort the channel, which will work
+if there is no blocked DREQ.
+
+It it times out, we can assume there is no AXI
+transfer in progress and reset anyway.
+
+The length of the timeout is observed at ~20us.

+Subject: [PATCH] panel-sitronix-st7701: Fix panel prepare over SPI
+
+A DSI write is issued in st7701_prepare even when the probed panel
+runs on SPI. In practice, this results in a panic with the
+vc4-kms-dpi-hyperpixel2r overlay active.
+
+Perform the equivalent write over SPI in this case.

+Subject: [PATCH] media: i2c: imx219: fix binning and rate_factor for 480p and
+ 1232p
+
+At a high FPS with RAW10, there is frame corruption for 480p because the
+rate_factor of 2 is used with the normal 2x2 bining [1]. This commit
+ties the rate_factor to the selected binning mode. For the 480p mode,
+analog 2x2 binning mode with a rate_factor of 2 is always used. For the
+1232p mode the normal 2x2 binning mode is used for RAW10 while analog
+2x2 binning mode is used for RAW8.

+This corresponds the sequence number with the actual number of frames
+produced by the sensor, not the number of frame buffers dequeued back

+Subject: [PATCH] dtoverlays: Fix pitft[28|35] overlays for 6.1 driver change.
+ (#5508)
+
+The overlays configured both irq-gpio and an interrupts/
+interrupt-parent configuration for the stmpe MFD device.
+
+irq-gpio was reworked in 6.1 and has issues with the configuration
+as provided. Removing it and using the interrupts/interrupt-parent
+configuration works fine, so do that.

+Subject: [PATCH] ALSA: pcm: fix ELD constraints for (E)AC3, DTS(-HD) and MLP
+ formats
+
+commit 04b49b90caeed0b5544ff616d654900d27d403b6 upstream.
+
+The SADs of compressed formats contain the channel and sample rate
+info of the audio data inside the compressed stream, but when
+building constraints we must use the rates and channels used to
+transport the compressed streams.
+
+eg 48kHz 6ch EAC3 needs to be transmitted as a 2ch 192kHz stream.
+
+This patch fixes the constraints for the common AC3 and DTS formats,
+the constraints for the less common MPEG, DSD etc formats are copied
+directly from the info in the SADs as before as I don't have the specs
+and equipment to test those.

+Subject: [PATCH] ASoC: hdmi-codec: fix channel info for compressed formats
+
+commit 4e0871333661d2ec0ed3dc00a945c2160eccae77 upstream.
+
+According to CTA 861 the channel/speaker allocation info in the
+audio infoframe only applies to uncompressed (PCM) audio streams.
+
+The channel count info should indicate the number of channels
+in the transmitted audio, which usually won't match the number of
+channels used to transmit the compressed bitstream.
+
+Some devices (eg some Sony TVs) will refuse to decode compressed
+audio if these values are not set correctly.
+
+To fix this we can simply set the channel count to 0 (which means
+"refer to stream header") and set the channel/speaker allocation to 0
+as well (which would mean stereo FL/FR for PCM, a safe value all sinks
+will support) when transmitting compressed audio.

+Subject: [PATCH] media: i2c: arducam_64mp: Modify the line length of 1280x720
+ resolution
+
+Arducam 64MP has specific requirements for the line length, and if these
+conditions are not met, the camera will not function properly. Under the
+previous configuration, once a stream off operation is performed, the
+camera will not output any data, even if a stream on operation is
+performed. This prevents us from switching from 1280x720 to another
+resolution.

+
+usbnet: smsc95xx: Fix indentation of smsc95xx_is_macaddr_param()
+
+smsc95xx_is_macaddr_param() is incorrectly indented, it uses 7 spaces
+instead of tabs.  Fix it.
+
+Fixes: aac7b105788e ("Allow mac address to be set in smsc95xx")

+usbnet: smsc95xx: Simplify MAC address parsing
+
+Parsing the MAC address provided on the kernel command line can be
+simplified quite a bit by taking advantage of the kernel's built-in
+mac_pton() helper.
+
+Likewise emitting the MAC address can be simplified with the %pM
+format string conversion.
+
+Signed-off-by: Lukas Wunner <lukas@wunner.de>
+
+usbnet: smsc95xx: Fix style issues in smsc95xx_is_macaddr_param()
+
+It is bad practice to have a function named ..._is_...() which has side
+effects.  So drop the 'is' from the name.
+
+Per kernel convention return 0 on success and a negative errno on
+failure.
+
+Validate the MAC address retrieved from the command line.

+
+The RV3032 RTC requires an additional DT property to enable trickle
+charging. Add a parameter - trickle-voltage-mv - to the i2c-rtc
+and i2c-rtc-gpio overlays to set it.

+Subject: [PATCH] can: isotp: add module parameter for maximum pdu size
+
+commit 96d1c81e6a0478535342dff6c730adb076cd84e8 upstream.
+
+With ISO 15765-2:2016 the PDU size is not limited to 2^12 - 1 (4095)
+bytes but can be represented as a 32 bit unsigned integer value which
+allows 2^32 - 1 bytes (~4GB). The use-cases like automotive unified
+diagnostic services (UDS) and flashing of ECUs still use the small
+static buffers which are provided at socket creation time.
+
+When a use-case requires to transfer PDUs up to 1025 kByte the maximum
+PDU size can now be extended by setting the module parameter
+max_pdu_size. The extended size buffers are only allocated on a
+per-socket/connection base when needed at run-time.
+
+changes since v2: https://lore.kernel.org/all/20230313172510.3851-1-socketcan@hartkopp.net
+- use ARRAY_SIZE() to reference DEFAULT_MAX_PDU_SIZE only at one place
+
+changes since v1: https://lore.kernel.org/all/20230311143446.3183-1-socketcan@hartkopp.net
+- limit the minimum 'max_pdu_size' to 4095 to maintain the classic
+  behavior before ISO 15765-2:2016

+Subject: [PATCH] drivers: irqchip: irq-bcm2835: Concurrency fix
+
+The commit shown in Fixes: aims to improve interrupt throughput by
+getting the handlers invoked on different CPU cores. It does so (*) by
+using an irq_ack hook to change the interrupt routing.
+
+Unfortunately, the IRQ status bits must be cleared at source, which only
+happens once the interrupt handler has run - there is no easy way for
+one core to claim one of the IRQs before sending the remainder to the
+next core on the list, so waking another core immediately results in a
+race with a chance of both cores handling the same IRQ. It is probably
+for this reason that the routing change is deferred to irq_ack, but that
+doesn't guarantee no clashes - after irq_ack is called, control returns
+to bcm2836_chained_handler_irq which proceeds to check for other pending
+IRQs at a time when the next core is probably doing the same thing.
+
+Since the whole point of the original commit is to distribute the IRQ
+handling, there is no reason to attempt to handle multiple IRQs in one
+interrupt callback, so the problem can be solved (or at least made much
+harder to reproduce) by changing a "while" into an "if", so that each
+invocation only handles one IRQ.
+
+(*) I'm not convinced it's as effective as claimed since irq_ack is
+called _after_ the interrupt handler, but the author thought it made a
+difference.
+
+See: https://github.com/raspberrypi/linux/issues/5214
+     https://github.com/raspberrypi/linux/pull/1794

+Subject: [PATCH] drm/ili9486: Resolve clash in spi_device_id names
+
+For "Really Good Reasons" [1] the SPI core requires a match
+between compatible device strings and the name in spi_device_id.
+
+The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35"
+and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing,
+so add them.
+
+Compatible string "ilitek,ili9486" is already used by
+staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an
+spi_device_id causes the incorrect module to be loaded, therefore remove
+this id.

+Subject: [PATCH] gpio_fsm: Rework the atomic-vs-non-atomic split
+
+Partition the code to separate atomic and non-atomic methods so that
+none of them have to handle both cases. The result avoids using deferred
+work unless necessary, and should be easier to understand.

+Subject: [PATCH] f2fs: fix to avoid NULL pointer dereference in
+ f2fs_issue_flush()
+
+commit b3d83066cbebc76dbac8a5fca931f64b4c6fff34 upstream.
+
+With below two cases, it will cause NULL pointer dereference when
+accessing SM_I(sbi)->fcc_info in f2fs_issue_flush().
+
+a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
+release SM_I(sbi)->fcc_info,
+
+- mount -o noflush_merge /dev/vda /mnt/f2fs
+- mount -o remount,flush_merge /dev/vda /mnt/f2fs  -- kthread_run() fails
+- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
+
+b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below
+testcase,
+
+- mount -o ro /dev/vda /mnt/f2fs
+- mount -o rw,remount /dev/vda /mnt/f2fs
+- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
+
+In order to fix this issue, let change as below:
+- fix error path handling in f2fs_create_flush_cmd_control().
+- allocate SM_I(sbi)->fcc_info even if readonly is on.

+Subject: [PATCH] ASoC: hdmi-codec: Fix broken channel map reporting
+
+Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for
+compressed formats") accidentally changed hcp->chmap_idx from
+ca_id, the CEA channel allocation ID, to idx, the index to
+the table of channel mappings ordered by preference.
+
+This resulted in wrong channel maps being reported to userspace,
+eg for 5.1 "FL,FR,LFE,FC" was reported instead of the expected
+"FL,FR,LFE,FC,RL,RR":
+
+~ # speaker-test -c 6 -t sine
+...
+ 0 - Front Left
+ 3 - Front Center
+ 1 - Front Right
+ 2 - LFE
+ 4 - Unknown
+ 5 - Unknown
+
+~ # amixer cget iface=PCM,name='Playback Channel Map' | grep ': values'
+  : values=3,4,8,7,0,0,0,0
+
+Revert this incorrect change so that channel maps are properly
+reported again.

+Subject: [PATCH] drm/edid: Add option to report basic audio support with a
+ generic edid
+
+Hardware that fails to read the edid is quite common.
+The kernel provides a mechanism to use one a of a few
+pre-built generic edid files for getting a basic video mode.
+
+However there is no easy was to add basic audio support,
+which requires a CTA extension block to report capabilities.
+
+Add an module option to request this.

+Subject: [PATCH] overlays: Add a sample hat_map
+
+The HAT map is way of associating named overlays with HATs whose
+EEPROMs were programmed with the contents of the overlay.
+Unfortunately, change in the DT and kernel drivers has meant that some
+of these embedded overlays no longer function, or even don't apply.
+
+The HAT map is a mapping from HAT UUIDs to overlay names. If a HAT with
+a listed UUID is detected, the embedded overlay is ignored and the
+overlay named in the mapping is loaded in its place.

+
+dtoverlays: Fix up edt5406 entries to match with vc4-kms-dsi-7inch

+vc4-kms-dsi-7inch expects the touch fragment to be named ts_i2c_frag,
+but edt5406 didn't do this.

+Subject: [PATCH] gpio_brcmstb: Allow to build for ARCH_BCM2835
+
+gpio-brcmstb: Report the correct bank width
+
+gpio: brcmstb: Use bank address as gpiochip label
+
+If the path to the device node is used as gpiochip label then
+gpio-brcmstb instances with multiple banks end up with duplicated
+names. Instead, use a combination of the driver name with the physical
+address of the bank, which is both unique and helpful for devmem
+debugging.

+
+gpio: mmio: Add DIRECT mode for shared access
+
+The generic MMIO GPIO library uses shadow registers for efficiency,
+but this breaks attempts by raspi-gpio to change other GPIOs in the
+same bank. Add a DIRECT mode that makes fewer assumptions about the
+existing register contents, but note that genuinely simultaneous
+accesses are likely to lose updates.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+gpio: brcmstb: Don't always clear interrupt mask
+
+If the GPIO controller is not being used as an interrupt source
+leave the interrupt mask register alone. On BCM2712 it might be used
+to generate interrupts to the VPU firmware, and on other devices it
+doesn't matter since no interrupts will be generated.

+Subject: [PATCH] pinctrl: bcm2712 pinctrl/pinconf driver
+
+pinctrl: bcm2712: Reject invalid pulls
+
+Reject attempts to set pulls on aon-sgpios, and fix pull shift
+values.
+
+pinctrl: bcm2712: Add 7712 support, fix 2712 count
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl-bcm2712: add EMMC pins so pulls can be set
+
+These pins have pad controls but not mux controls. They look enough like
+GPIOs to squeeze in at the end of the list though.
+
+pinctrl: bcm2712: correct BCM2712C0 AON_GPIO pad pull control offset
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+pinctrl: bcm2712: on C0 the regular GPIO pad control register moves too
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+pinctrl: bcm2712: Implement (partially) pinconf_get
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Convert to generic pinconf
+
+Remove the legacy brcm,* pin configuration support and replace it with
+a proper generic pinconf interface, using named functions instead of
+alt function numbers. This is nicer for users, less error-prone, and
+immune to some of the C0->D0 changes.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Remove vestigial pull parameter
+
+Now the legacy brcm, pinconf parameters are no longer supported, this
+custom pin config parameter is not needed.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Guard against bad func numbers
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: A better attempt at D0 support
+
+The BCM2712D0 sparse pinctrl maps play havoc with the old GPIO_REGS
+macro, so make the bit positions explicit. And delete the unwanted
+GPIO and pinmux declarations on D0.
+
+Note that a Pi 5 with D0 requires a separate DTS file with "bcm2712d0"
+compatible strings.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Delete base register constants
+
+BCM2712D0 deletes many GPIOs and their associated mux and pad bits,
+so much so that the offsets to the start of the pad control registers
+changes. Remove the constant offsets from the *GPIO_REGS macros,
+compensating by adjusting the per-GPIO values.

+Subject: [PATCH] mmc: brcmstb: add support for BCM2712
+
+BCM2712 has an SD Express capable SDHCI implementation and uses
+the SDIO CFG register block present on other STB chips.
+
+Add plumbing for SD Express handover and BCM2712-specific functions.
+
+Due to the common bus infrastructure between BCM2711 and BCM2712,
+the driver also needs to implement 32-bit IO accessors.
+
+mmc: brcmstb: override card presence if broken-cd is set
+
+Not just if the card is declared as nonremovable.
+
+sdhci: brcmstb: align SD express switchover with SD spec v8.00
+
+Part 1 of the Physical specification, figure 3-24, details the switch
+sequence for cards initially probed as SD. Add a missing check for DAT2
+level after switching VDD2 on.
+
+sdhci: brcmstb: clean up SD Express probe and error handling
+
+Refactor to avoid spurious error messages in dmesg if the requisite SD
+Express DT nodes aren't present.
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+mmc: sdhci-brcmstb: only use the delay line PHY for tuneable speeds
+
+The MMC core has a 200MHz core clock which allows the use of DDR50 and
+below without incremental phase tuning. SDR50/SDR104 and the EMMC HS200
+speeds require tuning.

+Right now a single implementation of enum_fmt() is used for all nodes

+and hog nodes. Split out from the list of supported_formats the
+V4L2_META_FMT_RPI_BE_CFG which is only used for the meta_out node, while
+V4L2_PIX_FMT_RPI_BE is kept in the list of supported_formats as it can
+be used as an opaque format for both meta_cap, video_cap and video_out
+nodes.

+
+Allow RGB input, not just Bayer (but only of those at once);
+Allow Wallpaper image formats. XXX They are not yet size-checked;
+Set "chicken bits" to test BURST_TRIM and AXI AWID/BID variation.

+drivers: media: pisp_be: Use the maximum number of config buffers
+
+Set PISP_BE_NUM_CONFIG_BUFFERS the the maximum number of possible
+buffers.  In the worst case, this overallocates config buffers, but
+given their size, it's not too much of a problem.

+media: pisp_be: Fix extra PM runtime put
+
+vidioc_streamoff callback can be called even if vidioc_streamon was
+never called. The driver currently does PM runtime get/put in these
+callbacks, which may lead to a put without a matching get.
+
+Fix this by moving the PM runtime get/put to vb2_ops's start_streaming &
+stop_streaming, which the framework makes sure won't get extra calls.

+
+irqchip: bcm2712-mip: add a quick hack to optionally shift MSI vectors
+
+There are two MIP peripherals in bcm2712, the first gets a first-class
+treatment where 64 consecutive GIC SPIs are assigned to all 64 output
+vectors. The second gets an agglomeration of 17 GIC SPIs, but only 8 of
+these are consecutive starting at the 8th output vector.
+
+For now, allow the use of this smaller contiguous range within a larger
+whole.

+
+macb: add platform device shutdown function. Prevents AXI master over PCIE from hanging when the host is rebooted.
+
+net: macb: increase polling interval for MDIO completion
+
+MDIO is a slow bus (single-digit MHz). Polling at 1us intervals
+is a bit aggressive, so increase to 100us as the transaction
+usually takes 100-200us to complete.

+
+net: macb: add hack to prevent TX stalls in a quiet system
+
+See https://github.com/raspberrypi/linux-2712/issues/89
+
+There is some critical window during TX where a further write to the
+TSTART bit while TX is active does not cause newly queued TX descriptors
+to be consumed.
+
+For now "wait a bit, then try anyway" seems to work.
+
+Requires further investigation, but this unsticks NFS reliably.

+net: macb: set default interrupt moderation for GEM hardware
+
+Defaulting to intmod = 0 is antisocial, as the MAC can generate over
+130,000 interrupts per second. 50us is a sensible default.

+
+pcie-brcmstb: Suppress read error responses
+
+If the link is down or the EP fails to return a read completion, the
+RC's default behaviour is to return an AXI error. This causes fatal
+exceptions on A76, so it's better to respond with all 1s instead.
+
+pcie-brcmstb: increase UBUS timeout to cater for link retrain events
+
+pcie-brcmstb: Handle additional inbound regions
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pcie-brcmstb: Add support for external MSI controller
+
+pcie-brcmstb: add a reasonable default traffic class to priority map
+
+BCM2712 supports multiple traffic classes (TCs) with independent
+maximally sized transfer queues for each TC. Traffic classes have no
+transaction ordering requirements between them, which facilitates
+out-of-order completions and arbitration between posted writes for
+data streams that have no dependence on each other.
+
+In addition to the above benefits of splitting endpoint traffic into
+individual queues, priorities can be assigned to traffic classes by
+a heuristic or deterministic mechanism. The heuristic elevates AXI
+QOS priority in accordance with the number of pending transfers in
+each TC's queue, but for true priority signalling a forwarding
+mechanism using vendor-defined messages is implemented.
+
+Receipt of a 3 DWORD VDM assigns a priority tag to a TC on-the-fly,
+and this tag corresponds to a configurable AXI QOS value.
+
+As a simple baseline, assign a linear map of AXI QOS to each tag.
+
+pcie: brcmstb: set up the VDM forwarding interface when setting up QoS
+
+pcie-brcmstb: add DT bindings for MPS-size Read Completion Mode
+
+This controller has an optional feature that allows read completion
+TLPs to be sized up to the Maximum Packet Size of a configured link.
+
+This can exceed the Read Completion Boundary of 128B specified in
+the PCIe specification, but depending on endpoint support may increase
+link read bandwidth significantly.

+
+pcie-brcmstb: fix BCM2712A0 PHY PM errata
+
+The power management clock is 54MHz not 50MHz, so adjust the PM clock period
+to suit. Powering off the PHY PLL in L1.2 is unsafe, so force it on.
+
+pcie-brcmstb: set CLKREQ functionality according to link partner support
+
+The RC supports either L1 with clock PM or L1 sub-state control, not both
+at the same time. Examine the link partner's capabilities to determine
+which is the most suitable scheme to use.
+
+pcie: brcmstb: don't reset block bridges in suspend or removal cases
+
+BCM2712 has a single rescal block for all three root complexes, and
+holding PCIE1's bridge in reset will hang the chip if a different
+RC wants to access any of the rescal registers.
+
+pcie: brcmstb: guard 2712-specific setup with a RC type check
+
+BCM2711 doesn't implement the UBUS control registers.
+
+pcie: brcmstb: On 2712 keeping the PLL powered in L1.x is not required
+
+A separate misconfiguration when enabling SSC (the MDIO registers no
+longer do the same thing on BCM2712) had the side-effect of breaking
+PLL powerdown and resume sequencing.
+
+Allow entry into a true L1.2 state where analogue is depowered.

+
+bcm2712: pcie: adjust PHY PLL setup to use a 54MHz input refclk
+
+Use canned MDIO writes from Broadcom that switch the ref_clk output
+pair to run from the internal fractional PLL, and set the internal PLL
+to expect a 54MHz input reference clock.
+
+Gen3 operation is not guaranteed to be stable in this setup, so default
+to gen2.
+
+This only works if the LCPLL is bypassed (requires latest bootloader).
+
+pcie: brcmstb: add missing register writes
+
+drivers: pcie: brcmstb: cater for BCM2712C0 bug dropping QoS on the floor
+
+The AXI QoS value extracted from the request fifo ends up as zero forever.
+Disabling this means that "panic" signalling doesn't do anything useful,
+but static priorites do work.
+
+Also align the selected TC:QoS map with RP1's expectations of service.

+
+drivers: pcie: brcmstb: shuffle TC priorities up to 8
+
+Use the range 8-11 which puts the highest below HVS but leaves space
+below for other 2712 masters.
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+drivers: pcie: brcmstb: optionally enable QoS features by DT for BCM2712
+
+It's a bad idea to universally enable "realtime" priorities for TCs
+across all the RC instances on the chip. Endpoints other than RP1 may
+make use of these, so you don't want e.g. NVMe descriptor fetches getting
+higher priority than your remote display.
+
+Add two optional DT properties controlling the behaviour - FIFO-based
+backpressure QoS or "message-based". Message-based signalling is
+fundamentally broken due to a chip bug, so it collapses into a set of
+static assignments that RP1 needs.
+
+The default if neither property is specified is to assign everything a
+QoS of 0.
+

+
+drivers: pcie: brcmstb: adjust completion timeouts for bcm2712
+
+Setting the RC config retry timeout makes CRS auto-polling work, but
+the UBUS timeout will override the config retry. Both need to be large.

+Subject: [PATCH] i2c: designware: Add SMBUS quick command support
+
+The SMBUS emulation code turns an SMBUS quick command into a zero-
+length read. This controller can't do zero length accesses, but it
+can do quick commands, so reverse the emulation. The alternative
+would be to properly implement the SMBUS support but that is a lot
+more work, and unnecessary just to get i2cdetect working.

+Subject: [PATCH] dmaengine: dw-axi-dmac: Fixes for RP1
+
+Don't assume that DMA addresses of devices are the same as their
+physical addresses - convert correctly.
+
+The CFG2 register layout is used when there are more than 8 channels,
+but also when configured for more than 16 target peripheral devices
+because the index of the handshake signal has to be made wider.
+
+Reset the DMAC on probe
+
+The driver goes to the trouble of tracking when transfers have been
+paused, but then doesn't report that state when queried.
+
+Not having APB registers is not an error - for most use cases it's
+not even of interest, it's expected. Demote the message to debug level,
+which is disabled by default.
+
+Each channel has a descriptor pool, which is shared between transfers.
+It is unsafe to treat the total number of descriptors allocated from a
+pool as the number allocated to a specific transfer; doing so leads
+to releasing buffers that shouldn't be released and walking off the
+ends of descriptor lists. Instead, give each transfer descriptor its
+own count.
+
+Support partial transfers:
+Some use cases involve streaming from a device where the transfer only
+proceeds when the device's FIFO occupancy exceeds a certain threshold.
+In such cases (e.g. when pulling data from a UART) it is important to
+know how much data has been transferred so far, in order that remaining
+bytes can be read from the FIFO directly by software.
+
+Add the necessary code to provide this "residue" value with a finer,
+sub-transfer granularity.
+
+In order to prevent the occasional byte getting stuck in the DMA
+controller's internal buffers, restrict the destination memory width
+to the source register width.

+Subject: [PATCH] ASOC: dwc: Fix 16-bit audio handling
+
+IMO the Synopsys datasheet could be clearer in this area, but it seems
+that the DMA data ports (DMATX and DMARX) expect left and right samples
+in alternate writes; if a stereo pair is pushed in a single 32-bit
+write, the upper half is ignored, leading to double speed audio with a
+confused stereo image. Make sure the necessary changes happen by
+updating the DMA configuration data in the hw_params method.
+
+The set_bclk_ratio change was made at a time when it looked like it
+could be causing an error, but I think the division of responsibilities
+is clearer this way (and the kernel log clearer without the info-level
+message).

+
+BCM2712 lacks the "asb" and "rpivid_asb" register ranges, but still
+requires the use of the bcm2835-power driver to reset the V3D block.

+
+Formerly, if configured using DT, CS GPIOs were driven from spi.c
+and it was possible for CS to be asserted (low) *before* starting
+to drive SCK. CS GPIOs have been brought under control of this
+driver in both ACPI and DT cases, with a fixup for GPIO polarity.

+Subject: [PATCH] spi: spi-gpio: Implement spidelay when requested bit rate <=
+ 1 Mbps
+
+Formerly the delay was omitted as bit-banged SPI seldom achieved
+even one Mbit/s; but some modern platforms can run faster, and
+some SPI devices may need to be clocked slower.

+Subject: [PATCH] drivers: char: add generic gpiomem driver
+
+Based on bcm2835-gpiomem.
+
+We allow export of the "GPIO registers" to userspace via a chardev as
+this allows for finer access control (e.g. users must be group gpio, root
+not required).
+
+This driver allows access to either rp1-gpiomem or gpiomem, depending on
+which nodes are populated in devicetree.
+
+RP1 has a different look-and-feel to BCM283x SoCs as it has split ranges
+for IO controls and the parallel registered OE/IN/OUT access. To handle
+this, the driver concatenates the ranges for an IO bank and the
+corresponding RIO instance into a contiguous buffer.

+Subject: [PATCH] drivers: hwmon: rp1-adc: check conversion validity before
+ supplying value
+
+The SAR ADC architecture may complete a conversion but instability in the

+
+The BCM2712 has a DMA-Lite controller that is basically a BCM2835-style
+DMA controller that supports 40 bits DMA addresses.
+
+We need it for HDMI audio to work, but this breaks BCM2835-38 so we
+should rework this later.

+There is a small driver for the Shared IOMMU TLB Cache.
+Each IOMMU instance is a separate device.
+
+IOMMUs are set up with a "pass-through" range covering
+the lowest 40BGytes (which should cover all of SDRAM)
+for the benefit of non-IOMMU-aware devices that share
+a physical IOMMU; and translation for addresses in the
+range 40GB to 42GB.
+
+An optional parameter adds a DMA offset (which otherwise
+would be lost?) to virtual addresses for DMA masters on a
+bus such as PCIe.

+

+[   25.183096] ->action->handler(): 000000002c09e646, bad_chained_irq+0x0/0x58
+[   25.190084]      IRQ_LEVEL set
+[   25.193142]    IRQ_NOPROBE set
+[   25.196198]  IRQ_NOREQUEST set
+[   25.199255]   IRQ_NOTHREAD set
+
+with:
+$ cat /proc/interrupts  | grep 31:
+ 31:          1          0          0          0     GICv2 129 Level     (null)
+
+The interrupt is described in DT with IRQ_TYPE_LEVEL_HIGH
+
+But the current compatible string uses the controller in edge triggered mode
+(as that config matches our register layout).
+
+Add a new compatible structure for level driven interrupt with our register layout.
+
+We had already been using this compatible string in device tree, so no change needed
+there.

+Subject: [PATCH] rtc: rtc-rpi: Add simple RTC driver for Raspberry Pi
+
+This supports setting and reading the real time clock
+and supports wakeup alarms.
+
+To support wake up alarms you want this bootloader config:
+ POWER_OFF_ON_HALT=1
+ WAKE_ON_GPIO=0
+
+You can test with:
+  echo +600 | sudo tee /sys/class/rtc/rtc0/wakealarm
+  sudo halt
+
+That will halt (in an almost no power state),
+then wake and restart after 10 minutes.

++* Raspberry Pi RTC
++
++This is a Linux interface to an RTC managed by firmware, hence it's
++virtual from a Linux perspective.
++
++The interface uses the firmware mailbox api to access the RTC registers.
++
++Required properties:
++compatible: should be "raspberrypi,rpi-rtc"
++firmware:   Reference to the RPi firmware device node.
++
++Example:
++
++	rpi_rtc: rpi_rtc {
++		compatible = "raspberrypi,rpi-rtc";
++		firmware = <&firmware>;
++	};

+Subject: [PATCH] hwmon: (pwm-fan) Add fan speed register support
+
+Some platforms include a fan-speed register that reports RPM directly
+as an alternative to counting interrupts from the fan tachometer input.
+Add support for reading a register at a given offset (rpm-offset) within
+a block declared in another node (rpm-regmap). This indirection allows
+the usual address mapping to be performed, and for address sharing with
+another driver.

+DLIST generation can get pretty tricky and there's not a lot of debug in

+Subject: [PATCH] drm/vc4: hvs: Print error if we fail an allocation
+
+We need to allocate a few additional structures when checking our
+atomic_state, especially related to hardware SRAM that will hold the
+plane descriptors (DLIST) and the current line context (LBM) during
+composition.
+
+Since those allocation can fail, let's add some error message in that
+case to help debug what goes wrong.

+Subject: [PATCH] drm/vc4: Introduce generation number enum
+
+With the introduction of the BCM2712 support, we will get yet another
+generation of display engine to support.
+
+The binary check of whether it's VC5 or not thus doesn't work anymore,
+especially since some parts of the driver will have changed with BCM2711,
+and some others with BCM2712.
+
+Let's introduce an enum to store the generation the driver is running
+on, which should provide more flexibility.

+Subject: [PATCH] drm/vc4: Make v3d paths unavailable on any generation newer
+ than vc4
+
+The V3D IP has been separate since BCM2711, so let's make sure we issue
+a WARN if we're running not only on BCM2711, but also anything newer.

+Subject: [PATCH] drm/vc4: hvs: Use switch statement to simplify
+ vc4_hvs_get_fifo_from_output
+
+Since we'll support BCM2712 soon, let's move the logic behind
+vc4_hvs_get_fifo_from_output() to a switch to extend it more easily.

+Subject: [PATCH] drm/vc4: hvs: Test if the EOF interrupts are enabled
+
+We currently enable the EOF interrupts through the CRTC destroy_state
+implementation.
+
+However, nothing guarantees that we can't call destroy_state multiple
+times in a row, and therefore before the EOF interrupt even happens.
+
+This means we would enable the interrupt multiple times but disable it
+only once. It wasn't an issue so far since the interrupts were only
+enabled by setting a bit in a register, but with BCM2712 we will use an
+external interrupt controller, with a refcounted interrupt.

+
+The HVS register set has been heavily modified in the BCM2712, and we'll

+
+The name hvs_regs is thus a bit too generic, so let's rename it to

+The BCM2712 will have a fairly different dlist, that will feature one

+Subject: [PATCH] drm/vc4: hvs: Rework LBM alignment
+
+With the introduction of the support for BCM2712, the check of whether
+we're running on vc5 or not to compute the LBM alignment requirement
+doesn't work anymore.
+
+Moreover, the LBM size will need to be computed in words for the
+BCM2712, while we've had sizes in bytes so far.
+
+Aligning on either 64 or 32 words is thus fairly harmful on BCM2712, so
+let's just explicitly align the size when needed, and then call
+drm_mm_insert_node_generic() with an alignment of 1.

+Subject: [PATCH] drm/vc4: hvs: Change prototype of __vc4_hvs_alloc to pass
+ registers
+
+The BCM2712 HVS has registers to report the size of the various SRAM the
+driver uses, and their size actually differ depending on the stepping.
+
+The initialisation of the memory pools happen in the __vc4_hvs_alloc()
+function that also allocates the main HVS structure, that will then hold
+the pointer to the memory mapping of the registers.
+
+This creates some kind of circular dependency that we can break by
+passing the mapping pointer as an argument for __vc4_hvs_alloc() to use
+to query to get the SRAM sizes and initialise the memory pools
+accordingly.

+Trying to read /sys/kernel/debug/dri/1/hdmi1_regs
+when the hdmi is disconnected results in a fatal system hang.
+
+This is due to the pm suspend code disabling the dvp clock.
+That is just a gate of the 108MHz clock in DVP_HT_RPI_MISC_CONFIG,
+which results in accesses hanging AXI bus.

+Subject: [PATCH] drm/vc4: Move the buffer offset out of the vc4_plane_state
+
+The offset fields in vc4_plane_state are described as being
+the offset for each buffer in the bo, however it is used to
+store the complete DMA address that is then written into the
+register.
+
+The DMA address including the fb ofset  can be retrieved
+using drm_fb_dma_get_gem_addr, and the offset adjustment due to
+clipping is local to vc4_plane_mode_set.
+Drop the offset field from the state, and compute the complete
+DMA address in vc4_plane_mode_set.

+Subject: [PATCH] drm/vc4: hvs: Remove ABORT_ON_EMPTY flag
+
+ABORT_ON_EMPTY chooses whether the HVS abandons the current frame
+when it experiences an underflow, or attempts to continue.
+
+In theory the frame should be black from the point of underflow,
+compared to a shift of sebsequent pixels to the left.
+
+Unfortunately it seems to put the HVS is a bad state where it is not
+possible to recover simply. This typically requires a reboot
+following the 'flip done timed out message'.
+
+Discussion with Broadcom has suggested we don't use this flag.
+All their testing is done with it disabled.
+
+Additionally setting BLANK_INSERT_EN causes the HDMI to output
+blank pixels on an underflow which avoids it losing sync.
+
+After this change a 'flip done timed out' due to sdram bandwidth
+starvation or too low a clock is recoverable once the situation improves.

+
+The HVS found in the BCM2712, while having a similar role, is very
+different from the one found in the previous SoCs. Indeed, the register
+layout is fairly different, and the DLIST format is new as well.
+
+Let's introduce the needed functions to support the new HVS.

+Subject: [PATCH] drm/vc4: crtc: Add support for BCM2712 PixelValves
+
+The PixelValves found on the BCM2712 are similar to the ones found in
+the previous generation.
+
+Compared to BCM2711, the pixelvalves only drive one HDMI controller each
+and HDMI1 PixelValve has a FIFO long enough to support 4k at 60Hz.

+Subject: [PATCH] drm/vc4: hdmi: Add support for BCM2712 HDMI controllers
+
+The HDMI controllers found in the BCM2712 are largely the ones found in
+the BCM2711 with a different PHY.
+
+There's some difference with how timings are split between registers,
+and HDMI1 is now able to run at 4k/60Hz.

+Subject: [PATCH] drm/vc4: txp: Add byte enable toggle bit
+
+The MOPLET doesn't have the BYTE_ENABLE field to set, but the TXP and
+MOP do, so let's add a boolean to control whether or not we need to set
+it.

+Subject: [PATCH] drm/vc4: txp: Add horizontal and vertical size offset toggle
+ bit
+
+The new writeback controllers that can be found on the BCM2712 require
+to have their horizontal and vertical size reduced by one.
+
+Let's tie that behaviour to the compatible so we can support both the
+new and old controllers.

+
+The BCM2712 MOP and MOPLET can handle addresses larger than 32bits
+through an extra register. We can easily support it and make it
+conditional based on the compatible through a boolean in our variant
+structure.

+Subject: [PATCH] drm/vc4: txp: Add support for BCM2712 MOP
+
+The BCM2712 has an evolution of what used to be called TXP in the
+earlier SoCs, but is now called MOP.
+
+There's a few differences still, so we can add a new compatible to deal
+with them easily.

+
+The DRM device pointer and the DRM encoder pointer are redundant, since

+drm_encoder->dev pointer.
+
+Let's remove the drm_device pointer argument.

+
+Instead of making them look them up in the DRM device, we can simply

+Subject: [PATCH] drm/vc4: tests: Add BCM2712 mock driver
+
+The BCM2712 has a simpler pipeline that can only output to a writeback
+connector and two HDMI controllers.
+
+Let's allow our kunit tests to create a mock of that pipeline.

+Subject: [PATCH] drm/vc4: kms: Avoid setting core and disp clocks for hdmi
+ modes
+
+On 2712, the firmware always runs these clock at a speed sufficient
+for dual 4kp60.
+
+The requests here prevent the gpu from going into its lowest voltage
+mode, so just skip the clock requests.
+
+With this applied the idle voltage on my pi 5 reduces from 0.7424V
+to 0.72V.

+Subject: [PATCH] ASoC: hdmi-codec: Fix broken channel map reporting
+
+Commit b84b53149476b22cc3b8677b771fb4cf06d1d455 upstream.
+
+Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for
+compressed formats") accidentally changed hcp->chmap_idx from
+ca_id, the CEA channel allocation ID, to idx, the index to
+the table of channel mappings ordered by preference.
+
+This resulted in wrong channel maps being reported to userspace,
+eg for 5.1 "FL,FR,LFE,FC" was reported instead of the expected
+"FL,FR,LFE,FC,RL,RR":
+
+~ # speaker-test -c 6 -t sine
+...
+ 0 - Front Left
+ 3 - Front Center
+ 1 - Front Right
+ 2 - LFE
+ 4 - Unknown
+ 5 - Unknown
+
+~ # amixer cget iface=PCM,name='Playback Channel Map' | grep ': values'
+  : values=3,4,8,7,0,0,0,0
+
+Switch this back to ca_id in case of PCM audio so the correct channel
+map is reported again and set it to HDMI_CODEC_CHMAP_IDX_UNKNOWN in
+case of non-PCM audio so the PCM channel map control returns "Unknown"
+channels (value 0).
+
+Fixes: 4e0871333661 ("ASoC: hdmi-codec: fix channel info for compressed formats")

+Subject: [PATCH] media: rp1: cfe: Fix use of freed memory on errors
+
+cfe_probe_complete() calls cfe_put() on both success and fail code paths.
+This works for the success path, but causes the cfe_device struct to be
+freed, even if it will be used later in the teardown code.
+
+Fix this by making the ref handling a bit saner: Let the video nodes
+have the refs as they do now, but also keep a ref in the "main" driver,
+released only at cfe_remove() time. This way the driver does not depend
+on the video nodes keeping the refs.

+Subject: [PATCH] media: rp1: cfe: Fix width & height in cfe_start_channel()
+
+The logic for handling width & height in cfe_start_channel() is somewhat
+odd and, afaics, broken. The code reads:
+
+bool start_fe = is_fe_enabled(cfe) &&
+                test_all_nodes(cfe, NODE_ENABLED, NODE_STREAMING);
+
+if (start_fe || is_image_output_node(node)) {
+        width = node->fmt.fmt.pix.width;
+        height = node->fmt.fmt.pix.height;
+}
+
+cfe_start_channel() is called for all video nodes that will be used. So
+this means that if, say, fe_stats is enabled as the last node, start_fe
+will be true, and width and height will be taken from fe_stats' node.
+The width and height will thus contain garbage, which then gets
+programmed to the csi2 registers.
+
+It seems that this often still works fine, though, probably if the width
+& height are large enough.
+
+Drop the above code, and instead get the width & height from the csi2
+subdev's sink pad for the csi2 channel that is used. For metadata the
+width & height will be 0 as before.

+Subject: [PATCH] media: rp1: csi2: Track CSI-2 errors
+
+Track the errors from the CSI-2 receiver: overflows and discards. These
+are recorded in a table which can be read by the userspace via debugfs.
+
+As tracking the errors may cause much more interrupt load, the tracking
+needs to be enabled with a module parameter.
+
+Note that the recording is not perfect: we only record the last
+discarded DT for each discard type, instead of recording all of them.
+This means that e.g. if the device is discarding two unmatched DTs, the
+debugfs file only shows the last one recorded. Recording all of them
+would need a more sophisticated recording system to avoid the need of a
+very large table, or dynamic allocation.

+When pisp_fe_pad_set_fmt() is given an mbus code that CFE does not

+Subject: [PATCH] vc4/drm: Remove the clear of SCALER_DISPBKGND_FILL
+
+Since "drm/vc4: hvs: Support BCM2712 HVS" booting Pi4
+with dual 4kp30 displays connected fails with:
+vc4-drm gpu: [drm] *ERROR* [CRTC:107:pixelvalve-4] flip_done timed out
+
+It has been tracked down to the referenced commit adding a
+path to clear the SCALER_DISPBKGND_FILL when not required.
+
+Dual 4kp30 works with a core clock of 297MHz when background fill
+is enabled, but requires a higher value with it disabled.
+320MHz still fails, while 330MHz seems okay.
+
+Lets always enable background fill for Pi0-4.
+
+Fixes: e84da235223d ("drm/vc4: hvs: Support BCM2712 HVS")

+In order to use iommu on hevc set dma mask_and_coherent in probe.
+I am assured dma_set_mask_and_coherent is benign on Pi4 (which has
+no iommu) and it seems to be so in practice.
+Also adds a bit of debug to make internal buffer allocation failure
+easier to spot in future

+Subject: [PATCH] vc04_services: bcm2835-codec: Correct alignment requirements
+ for YUYV
+
+The firmware wants the YUYV format stride alignment to be to a multiple
+of 32pixels / 64 bytes. The kernel driver was configuring it to a multiple
+of 16 pixels / 32 bytes, which then failed when it tried starting to
+stream.
+
+Correct the alignment requirements.

+Subject: [PATCH] input: touchscreen: edt-ft5x06: Suppress bogus data on
+ startup
+
+When polled without the use of IRQ, FT5x06 registers may return
+undefined initial data, causing unwanted touches or event spamming.
+A simple way to filter this out is to suppress touches until the
+TD_STATUS register changes for the first time.
+
+Increase the delay before first polling to 300ms, to avoid
+transient I2C read flakiness that seems to occur after reset.

+bcm2708_fb is disabled by the vc4-kms-v3d overlay, which means that the
+DMA memcpy support it provides is not available to allow vclog to read
+the VC logs from the top 16MB on Pi 2 and Pi 3. Add the code to the
+vc_mem driver, which will still be enabled.
+
+It ought to be possible to do a proper DMA_MEM_TO_MEM copy via the
+generic DMA customer API, but that can be a later step.

+Subject: [PATCH] drm/vc4: Correct address offset for planes with src_[xy]
+ offsets
+
+11cf37e741b4 switched to using drm_fb_dma_get_gem_addr instead of
+drm_fb_dma_get_gem_obj and adding fb->offset[].
+
+However the tiled formats need to compute the offset in a more
+involved manner than drm_fb_dma_get_gem_addr applies, and we
+were ending up with the offset for src_[xy] being applied twice.
+
+Switch back to using drm_fb_dma_get_gem_obj and fully computing
+the offsets ourselves.
+
+Fixes: 11cf37e741b4 ("drm/vc4: Move the buffer offset out of the vc4_plane_state")

+Subject: [PATCH] drivers: media: rp1_cfe: Fix link validate test for pixel
+ format
+
+Now that we have removed unique PISP media bus codes, the cfe format
+table has multiple entries with the same media bus code for 16-bit
+formats. The test in cfe_video_link_validate() did not account for this.
+Fix it by testing the media bus code and the V4L2 pixelformat 4cc
+together.
+
+As a drive-by, ensure we have a valid CSI2 datatype id when programming
+the hardware block.

+Subject: [PATCH] dt: Add overrides for drm framebuffer allocations on Pi5
+
+Adds dtparam overrides to the base Pi5 DT such that vc4,
+DSI0, DSI1, or DPI can be requested to be /dev/fb[012].
+No override is specified by default, so the order will be
+based on probe order (aka semi-random). Any device that
+doesn't have an override specified will be placed above
+all specified overrides. Having an fb1 or fb2 override but
+no fb0 one will result in no console via fbcon.

+Most bus masters on Pi 5 have access to at least the lower 4GB, but
+the old DWC OTG controller is still restricted to the first 1GB.
+Create a Pi 5-specific version of the overlay including a fragment
+that ensures the swiotlb bounce buffers are allocated in that

+(*) Ideally all fragments would appear in the file in the order in which
+they should be merged, but that is easy to forget and can be awkward, so
+the firmware merges all "intra" fragments (those that target other
+fragments in the overlay) before "inter" fragments (those that target
+the base DTB). However, intra fragments that target other intra
+fragments is a level of nesting too far for this logic to cope, so they
+must appear before the fragments they target.

+
+The horizontal scaler has been disabled but actually the sensor is not
+binning horizontally, resulting in images that are stretched 2x
+horizontally (missing the right half of the field of view completely).
+
+Therefore we must additionally set the horizontal binning mode. There

+
+This reverts commit 5dba6ec6f4f2ac9ed8556116481b107e50e15251.
+
+With careful use of qualified firmware names there is no need for the
+ability to override the device names based on Device Tree properties.

+
+Use the sensor provided link frequency to set the DPHY timing parameters
+on stream_on. This replaces the hard-coded 999 MHz value currently being
+used. As a fallback, revert to the original 999 Mhz link frequency.
+
+As a drive-by, fix a 80-character line formatting error.

+Subject: [PATCH] drm/vc4: Correct logic on stopping an HVS channel
+
+When factoring out __vc4_hvs_stop_channel, the logic got inverted from
+	if (condition)
+	  // stop channel
+to
+	if (condition)
+	  goto out
+	//stop channel
+	out:
+and also changed the exact register writes used to stop the channel.
+
+Correct the logic so that the channel is actually stopped, and revert
+to the original register writes.

+Subject: [PATCH] drm/vc4: Free all stale dlists if channel is disabled
+
+The code handling freeing stale dlists had 2 issues:
+- it disabled the interrupt as soon as the first EOF interrupt
+  occurred, even if it didn't clear all stale allocations, thus
+  leading to stale entries
+- It didn't free stale entries from disabled channels, so eg
+  "kmstest -c 0" could leave a stale alloc on channel 1 floating
+  around.
+
+Keep the interrupt enabled whilst there are any outstanding
+allocs, and discard those on disabled channels. This second
+channel does require us to call vc4_hvs_stop_channel from
+vc4_crtc_atomic_disable so that the channel actually gets stopped.

+Subject: [PATCH] drm/vc4: crtc: Support odd horizontal timings on BCM2712
+
+BCM2711 runs pixelvalve at two pixels per clock cycle which results
+in an unfortunate limitation that odd horizontal timings are not
+possible. This is apparent on the standard DMT mode of 1366x768@60
+which cannot be driven with correct timing.
+
+BCM2712 defaults to the same behaviour, but has a mode to support
+odd timings. While internally it still runs at two pixels per clock,
+setting the PV_VCONTROL_ODD_TIMING bit makes it appear externally
+to behave as it is one pixel per clock.
+
+Switching to this mode fixes 1366x768@60 mode, and other custom
+resultions with odd horizontal timings.

+Subject: [PATCH] spi: dw-dma: Get the last DMA scoop out of the FIFO
+
+With a DMA FIFO threshold greater than 1 (encoded as 0), it is possible
+for data in the FIFO to be inaccessible, causing the transfer to fail
+after a timeout. If the transfer includes a transmission, reduce the
+RX threshold when the TX completes, otherwise use 1 for the whole
+transfer (inefficient, but not catastrophic at SPI data rates).

+Subject: [PATCH] drivers: mmc: sdhci: add SPURIOUS_INT_RESP quirk
+
+Certain controllers (dwc-mshc) generate timeout conditions separately to
+command-completion conditions, where the end result is interrupts are
+separated in time depending on the current SDCLK frequency.
+
+This causes spurious interrupts if SDCLK is slow compared to the CPU's
+ability to process and return from interrupt. This occurs during card
+probe with an empty slot where all commands that would generate a
+response time out.
+
+Add a quirk to squelch command response interrupts when a command
+timeout interrupt is received.

+Subject: [PATCH] drivers: media: imx708: Adjust broken line correction
+ parameter
+
+In full-resolution mode, the LPF_INTENSITY_EN and LPF_INTENSITY
+registers control Quad Bayer Re-mosaic broken line correction.
+Expose this as a module parameter "qbc_adjust": zero disables
+the correction and values in the range 2 to 5 set its strength.
+
+There is a trade-off between coloured and monochrome patterns.
+The previous fixed value 4 could produce ladder/spots artefacts
+in coloured textures. The new default value 2 may suit a wider
+range of scenes.

-Subject: [PATCH 3/4] r8169: use tp_to_dev instead of open code
-
-The open code is defined as a helper function(tp_to_dev) on r8169_main.c,
-which the open code is &tp->pci_dev->dev. The helper function was added
-in commit 1e1205b7d3e9 ("r8169: add helper tp_to_dev"). And then later,
-commit f1e911d5d0df ("r8169: add basic phylib support") added
-r8169_phylink_handler function but it didn't use the helper function.
-Thus, tp_to_dev() replaces the open code. This patch doesn't change logic.

-Script to create a U-Boot flashable multi-image blob.
-
-This script creates a multi-image blob, from a bunch of images, and
-adds a U-Boot shell script to the blob, that can flash the images from
-within U-Boot. The procedure to use this script is listed below.
-
-  1. Create an images folder. Ex: my-pack
-
-  2. Copy all the images to be flashed into the folder.
-
-  3. Copy the partition MBN file into the folder. The file should be
-     named 'partition.mbn'. This is used to determine the offsets for
-     each of the named partitions.
-
-  4. Create a flash configuration file, specifying the images be
-     flashed, and the partition in which the images is to be
-     flashed. The flash configuration file can be specified using the
-     -f option, default is flash.conf.
-
-  5. Invoke 'pack' with the folder name as argument, pass flash
-     parameters as arguments if required. A single image file will
-     be created, out side the images folder, with .img suffix. Ex:
-     my-pack.img
-
-  6. Transfer the file into a valid SDRAM address and invoke the
-     following U-Boot command to flash the images. Replace 0x41000000,
-     with address location where the image has been loaded. The script
-     expects the variable 'imgaddr' to be set.
-
-     u-boot> imgaddr=0x88000000 source $imgaddr:script

-Subject: [PATCH 2/2] clk: fix apss cpu overclocking
-
-There's an interaction issue between the clk changes:"
-clk: qcom: ipq4019: Add the apss cpu pll divider clock node
-clk: qcom: ipq4019: remove fixed clocks and add pll clocks
-" and the cpufreq-dt.
-
-cpufreq-dt is now spamming the kernel-log with the following:
-
-[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
-for freq 761142857 (-34)
-
-This only happens on certain devices like the Compex WPJ428
-and AVM FritzBox!4040. However, other devices like the Asus
-RT-AC58U and Meraki MR33 work just fine.
-
-The issue stem from the fact that all higher CPU-Clocks
-are achieved by switching the clock-parent to the P_DDRPLLAPSS
-(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
-as part of the DDR calibration.
-
-For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
-at round 533 MHz (ddrpllsdcc = 190285714 Hz).
-
-whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
-clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
-
-This patch attempts to fix the issue by modifying
-clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
-to use a new qcom_find_freq_close() function, which returns the closest
-matching frequency, instead of the next higher. This way, the SoC in
-the FB4040 (with its max clock speed of 710.4 MHz) will no longer
-try to overclock to 761 MHz.
-
-Fixes: d83dcacea18 ("clk: qcom: ipq4019: Add the apss cpu pll divider clock node")

-Subject: [PATCH] arm: compressed: add appended DTB section
-
-This adds a appended_dtb section to the ARM decompressor
-linker script.
-
-This allows using the existing ARM zImage appended DTB support for
-appending a DTB to the raw ELF kernel.
-
-Its size is set to 1MB max to match the zImage appended DTB size limit.
-
-To use it to pass the DTB to the kernel, objcopy is used:
-
-objcopy --set-section-flags=.appended_dtb=alloc,contents \
-	--update-section=.appended_dtb=<target>.dtb vmlinux
-
-This is based off the following patch:
-https://github.com/openwrt/openwrt/commit/c063e27e02a9dcac0e7f5877fb154e58fa3e1a69

-Subject: [PATCH 2/2] arm: compressed: set ipq40xx watchdog to allow boot
-
-For IPQ40XX systems where the SoC watchdog is activated before linux,
-the watchdog timer may be too small for linux to finish uncompress,
-boot, and watchdog management start.
-If the watchdog is enabled, set the timeout for it to 30 seconds.
-The functionality and offsets were copied from:
-drivers/watchdog/qcom-wdt.c qcom_wdt_set_timeout & qcom_wdt_start
-The watchdog memory address was taken from:
-arch/arm/boot/dts/qcom-ipq4019.dtsi
-
-This was required on Mikrotik IPQ40XX consumer hardware using Mikrotik's
-RouterBoot bootloader.

-Subject: [PATCH] skbuff: add DSA specific data to struct skb_shared_info
-
-All of the already existing DSA tagging protocol drivers
-are storing the tagging data directly into the skb. In most
-cases that is the only way to send the required information
-to the underlying ethernet switch.
-
-However on certain platforms (like the Qualcomm IPQ40xx
-SoCs) the built-in ethernet switch is connected directly
-to an ethernet MAC, and the tagging information must be
-sent out-of-band which is done directly via the hardware
-TX descriptors of the ethernet MAC.
-
-In such cases, putting the information into the skb causes
-unneccesary overhead, because the ethernet driver must
-remove that before sending the ethernet frame towards to
-the hardware.
-
-This change adds two new DSA specific fields to struct
-skb_shared_info which makes it possible to send the
-tagging information via skb->shinfo. With this approach,
-the twofold modifications of the skb data can be avoided.

-Subject: [PATCH] net: dsa: tag_ipq4019: add shinfo based tagging driver for
- IPQ40xx
-
-This change adds a tagging protocol driver for the built-in
-ethernet switch of the Qualcomm Atheros IPQ4019 SoCs.
-
-In comparison to the existing tagging protocols this hardware
-requires a slightly different approach because the switch does
-not use in-band tags.
-
-On the receive path, the source port information is embedded
-into the RX descriptors of the ethernet MAC hardware. Similarly,
-the destination port mask must be sent via the TX descriptors
-of the ethernet MAC when a packet is sent towards the switch.
-
-In order to support this special requirements, this patch
-adds a new tagging protocol driver.
-
-The driver extracts the source port information directly
-from the 'receive return descriptor' of the ethernet MAC.
-It is possible because that descriptor is part of the skb
-received from the ethernet driver.
-
-Unfortunatley, it is not possible to put the destination
-port information directly to the TX descriptors, because
-those are handled internally by the driver of the ethernet
-hardware.
-
-To overcome this limitation, this tagging driver uses the
-DSA specific fields in skb->shinfo to send the destination
-port information to the ethernet driver.
-
-A similar tagging driver is exist but that uses skb
-extensions which causes unnecessary overhead.

-Subject: [PATCH] net: phy: Add Qualcom QCA807x driver
-
-This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
-
-They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s.
-
-They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC, while second one is SGMII for connection to MAC or fiber.
-
-Both models have a combo port that supports 1000BASE-X and 100BASE-FX fiber.
-
-Each PHY inside of QCA807x series has 4 digitally controlled output only pins that natively drive LED-s.
-But some vendors used these to driver generic LED-s controlled by userspace,
-so lets enable registering each PHY as GPIO controller and add driver for it.
-
-These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x boards.

-Subject: [PATCH] kbuild: Allow DTB overlays to built from .dtso named source
- files
-
-Currently DTB Overlays (.dtbo) are build from source files with the same
-extension (.dts) as the base DTs (.dtb). This may become confusing and
-even lead to wrong results. For example, a composite DTB (created from a
-base DTB and a set of overlays) might have the same name as one of the
-overlays that create it.
-
-Different files should be generated from differently named sources.
- .dtb  <-> .dts
- .dtbo <-> .dtso
-
-We do not remove the ability to compile DTBO files from .dts files here,
-only add a new rule allowing the .dtso file name. The current .dts named
-overlays can be renamed with time. After all have been renamed we can
-remove the other rule.

-Subject: [PATCH 10/19] arm64: dts: mt7986: add Bananapi R3
-
-Add support for Bananapi R3 SBC.
-
-- SD/eMMC support (switching first 4 bits of data-bus with sw6/D)
-- SPI-NAND/NOR support (switched CS by sw5/C)
-- all rj45 ports and both SFP working (eth1/lan4)
-- all USB-Ports + SIM-Slot tested
-- i2c and all uarts tested
-- wifi tested (with eeprom calibration data)
-
-The device can boot from all 4 storage options. Both, SPI and MMC, can
-be switched using hardware switches on the board, see
-https://wiki.banana-pi.org/Banana_Pi_BPI-R3#Jumper_setting

- bl2
-
-To store uncompressed bl2 more space is required than partition is
-actually defined.
-
-There is currently no known usage of this reserved partition.
-Openwrt uses same partition layout.
-
-We added same change to u-boot with commit d7bb1099 [1].

-Subject: [PATCH 19/19] arm64: dts: mt7986: increase bl2 partition on NAND of
- Bananapi R3
-
-The bootrom burned into the MT7986 SoC will try multiple locations on
-the SPI-NAND flash to load bl2 in case the bl2 image located at the the
-previously attempted offset is corrupt.
-
-Use 0x100000 instead of 0x80000 as partition size for bl2 on SPI-NAND,
-allowing for up to four redundant copies of bl2 (typically sized a
-bit less than 0x40000).
-

-With the current range specified for the CPU interface there is an
-error message at boot:
-
-GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
-
-Setting irqchip.gicv2_force_probe=1 in bootargs results in:
-
-GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
-GIC: Adjusting CPU interface base to 0x000000001032f000
-GIC: Using split EOI/Deactivate mode
-
-Using the adjusted CPU interface base and 8K size results in only the
-final line remaining and fully working system as well as /proc/interrupts
-showing additional IPI3,4,5,6:
-
-IPI3:         0          0       CPU stop (for crash dump) interrupts
-IPI4:         0          0       Timer broadcast interrupts
-IPI5:         0          0       IRQ work interrupts
-IPI6:         0          0       CPU wake-up interrupts

-Subject: [PATCH] mediatek: mt7623: fix thermal zone
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Raising the temperatures for passive and active trips. @VA1DER
-proposed at issue 9396 to remove passive trip. This commit relates to
-his suggestion.
-
-Without this patch. the CPU will be throttled all the way down to 98MHz
-if the temperature rises even a degree above the trip point, and it was
-further discovered that if the internal temperature of the device is
-above the first trip point temperature when it boots then it will start
-in a throttled state and even
-$ echo disabled > /sys/class/thermal/thermal_zone0/mode
-will have no effect.
-
-The patch increases the passive trip point and active cooling map. The
-throttling temperature will then be at 77°C and 82°C, which is still a
-low enough temperature for ARM devices to not be in the real danger
-zone, and gives some operational headroom.

-Subject: [PATCH 1/2] pinctrl: mt7986: allow configuring uart rx/tx and rts/cts
- separately
-
-Some mt7986 boards use uart rts/cts pins as gpio,
-This patch allows to change rts/cts to gpio mode, but keep
-rx/tx as UART function.

-Subject: [PATCH 01/15] clk: mediatek: clk-gate: Propagate struct device with
- mtk_clk_register_gates()
-
-Commit e4c23e19aa2a ("clk: mediatek: Register clock gate with device")
-introduces a helper function for the sole purpose of propagating a
-struct device pointer to the clk API when registering the mtk-gate
-clocks to take advantage of Runtime PM when/where needed and where
-a power domain is defined in devicetree.
-
-Function mtk_clk_register_gates() then becomes a wrapper around the
-new mtk_clk_register_gates_with_dev() function that will simply pass
-NULL as struct device: this is essential when registering drivers
-with CLK_OF_DECLARE instead of as a platform device, as there will
-be no struct device to pass... but we can as well simply have only
-one function that always takes such pointer as a param and pass NULL
-when unavoidable.
-
-This commit removes the mtk_clk_register_gates() wrapper and renames
-mtk_clk_register_gates_with_dev() to the former and all of the calls
-to either of the two functions were fixed in all drivers in order to
-reflect this change; also, to improve consistency with other kernel
-functions, the pointer to struct device was moved as the first param.
-
-Since a lot of MediaTek clock drivers are actually registering as a
-platform device, but were still registering the mtk-gate clocks
-without passing any struct device to the clock framework, they've
-been changed to pass a valid one now, as to make all those platforms
-able to use runtime power management where available.
-
-While at it, some much needed indentation changes were also done.

-Subject: [PATCH 02/15] clk: mediatek: cpumux: Propagate struct device where
- possible
-
-Take a pointer to a struct device in mtk_clk_register_cpumuxes() and
-propagate the same to mtk_clk_register_cpumux() => clk_hw_register().
-Even though runtime pm is unlikely to be used with CPU muxes, this
-helps with code consistency and possibly opens to commonization of
-some mtk_clk_register_(x) functions.

-Subject: [PATCH] clk: mediatek: clk-mtk: Extend mtk_clk_simple_probe()
-
-As a preparation to increase probe functions commonization across
-various MediaTek SoC clock controller drivers, extend function
-mtk_clk_simple_probe() to be able to register not only gates, but
-also fixed clocks, factors, muxes and composites.

- clocks enabled
-
-Instead of calling clk_prepare_enable() on a bunch of clocks at probe
-time, set the CLK_IS_CRITICAL flag to the same as these are required
-to be always on, and this is the right way of achieving that.

-Subject: [PATCH] clk: mediatek: add MT7981 clock support
-
-Add MT7981 clock support, include topckgen, apmixedsys, infracfg and
-ethernet subsystem clocks.
-
-The drivers are based on clk-mt7981.c which can be found in MediaTek's
-SDK sources. To be fit for upstream inclusion the driver has been split
-into clock domains and the infracfg part has been significantly
-de-bloated by removing all the 1:1 factors (aliases).

-Subject: [PATCH] net: phy: add driver for MediaTek SoC built-in GE PHYs
-
-Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
-PHYs which require calibration data from the SoC's efuse.
-Despite the similar design the driver doesn't share any code with the
-existing mediatek-ge.c.
-Add support for such PHYs by introducing a new driver with basic
-support for MediaTek SoCs MT7981 and MT7988 built-in 1GE PHYs.

-Subject: [PATCH] net: phy: mediatek-ge-soc: initialize MT7988 PHY LEDs default
- state
-
-Initialize LEDs and set sane default values.
-Read boottrap register and apply LED polarities accordingly to get
-uniform behavior from all LEDs on MT7988.
-Requires syscon phandle 'mediatek,pio' present in parenting MDIO bus
-which should point to the syscon holding the boottrap register.

-Subject: [PATCH] net: phy: mxl-gpy: don't use SGMII AN if using phylink
-
-MAC drivers using phylink expect SGMII in-band-status to be switched off
-when attached to a PHY. Make sure this is the case also for mxl-gpy which
-keeps SGMII in-band-status in case of SGMII interface mode is used.

-Subject: [PATCH 1/2] thermal/drivers/mtk: use function pointer for
- raw_to_mcelsius
-
-Instead of having if-else logic selecting either raw_to_mcelsius_v1 or
-raw_to_mcelsius_v2 in mtk_thermal_bank_temperature introduce a function
-pointer raw_to_mcelsius to struct mtk_thermal which is initialized in the
-probe function.

-
-Commit fb34a9ae383a ("pinctrl: mediatek: support rsel feature")
-introduced SoC specify 'pull_type' attribute to mtk_pinconf_bias_set_combo
-and mtk_pinconf_bias_get_combo, and make the functions able to support
-almost all Mediatek SoCs that use pinctrl-mtk-common-v2.c.
-
-This patch enables pinctrl_moore to support these functions.

-MIME-Version: 1.0

-
-The driver can match only via the DT table so the table should be always
-used and the of_match_ptr does not have any sense (this also allows ACPI
-matching via PRP0001, even though it might not be relevant here).

-Subject: [PATCH net-next 2/2] net: ethernet: mtk_wed: move cpuboot in a
- dedicated dts node
-
-Since the cpuboot memory region is not part of the RAM SoC, move cpuboot
-in a deidicated syscon node.
-This patch helps to keep backward-compatibility with older version of
-uboot codebase where we have a limit of 8 reserved-memory dts child
-nodes.
-Keep backward-compatibility with older dts version where cpuboot was
-defined as reserved-memory child node.

+Subject: [PATCH net-next 1/2] net: ethernet: mediatek: split tx and rx fields
+ in mtk_soc_data struct
+
+Split tx and rx fields in mtk_soc_data struct. This is a preliminary
+patch to roll back to QDMA for MT7986 SoC in order to fix a hw hang
+if the device receives a corrupted packet.

+Subject: [PATCH net-next 2/2] net: ethernet: mediatek: use QDMA instead of
+ ADMAv2 on MT7981 and MT7986
+
+ADMA is plagued by RX hangs which can't easily detected and happen upon
+receival of a corrupted package.
+Use QDMA just like on netsys v1 which is also still present and usable, and
+doesn't suffer from that problem.

-Subject: [PATCH v2] PCI: aardvark: Implement workaround for PCIe Completion Timeout
-Date:   Tue,  2 Aug 2022 14:38:16 +0200
-Message-Id: <20220802123816.21817-1-pali@kernel.org>
-X-Mailer: git-send-email 2.20.1
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Precedence: bulk
-List-ID: <linux-pci.vger.kernel.org>
-X-Mailing-List: linux-pci@vger.kernel.org
-
-Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions
-document describes in erratum 3.12 PCIe Completion Timeout (Ref #: 251),
-that PCIe IP does not support a strong-ordered model for inbound posted vs.
-outbound completion.
-
-As a workaround for this erratum, DIS_ORD_CHK flag in Debug Mux Control
-register must be set. It disables the ordering check in the core between
-Completions and Posted requests received from the link.
-
-Marvell also suggests to do full memory barrier at the beginning of
-aardvark summary interrupt handler before calling interrupt handlers of
-endpoint drivers in order to minimize the risk for the race condition
-documented in the Erratum between the DMA done status reading and the
-completion of writing to the host memory.
-
-More details about this issue and suggested workarounds are in discussion:
-https://lore.kernel.org/linux-pci/BN9PR18MB425154FE5019DCAF2028A1D5DB8D9@BN9PR18MB4251.namprd18.prod.outlook.com/t/#u
-
-It was reported that enabling this workaround fixes instability issues and
-"Unhandled fault" errors when using 60 GHz WiFi 802.11ad card with Qualcomm
-QCA6335 chip under significant load which were caused by interrupt status
-stuck in the outbound CMPLT queue traced back to this erratum.
-
-This workaround fixes also kernel panic triggered after some minutes of
-usage 5 GHz WiFi 802.11ax card with Mediatek MT7915 chip:
-
-    Internal error: synchronous external abort: 96000210 [#1] SMP
-    Kernel panic - not syncing: Fatal exception in interrupt

- private trigger
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add support for enabling MCU controlled mode of the Turris Omnia LEDs
-via a LED private trigger called "omnia-mcu".
-
-When in MCU controlled mode, the user can still set LED color, but the
-blinking is done by MCU, which does different things for various LEDs:
-- WAN LED is blinked according to the LED[0] pin of the WAN PHY
-- LAN LEDs are blinked according to the LED[0] output of corresponding
-  port of the LAN switch
-- PCIe LEDs are blinked according to the logical OR of the MiniPCIe port
-  LED pins
-
-For a long time I wanted to actually do this differently: I wanted to
-make the netdev trigger to transparently offload the blinking to the HW
-if user set compatible settings for the netdev trigger.
-There was some work on this, and hopefully we will be able to complete
-it sometime, but since there are various complications, it will probably
-not be soon.
-
-In the meantime let's support HW controlled mode via this private LED
-trigger. If, in the future, we manage to complete the netdev trigger
-offloading, we can still keep this private trigger for backwards
-compatiblity, if needed.
-
-We also set "omnia-mcu" to cdev->default_trigger, so that the MCU keeps
-control until the user first wants to take over it. If a different
-default trigger is specified in device-tree via the
-`linux,default-trigger` property, LED class will overwrite
-cdev->default_trigger, and so the DT property will be respected.

-Using binary brightness makes more sense for this controller, because
-internally in the MCU it works that way: the LED has a color, and a
-state whether it is ON or OFF.
-
-The resulting brightness computation with led_mc_calc_color_components()
-will now always result in either (0, 0, 0) or the multi_intensity value.

-Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
-
-The command-line arguments provided by the boot loader will be
-appended to a new device tree property: bootloader-args.
-If there is a property "append-rootblock" in DT under /chosen
-and a root= option in bootloaders command line it will be parsed
-and added to DT bootargs with the form: <append-rootblock>XX.
-Only command line ATAG will be processed, the rest of the ATAGs
-sent by bootloader will be ignored.
-This is usefull in dual boot systems, to get the current root partition
-without afecting the rest of the system.
-
-Signed-off-by: Adrian Panella <ianchi74@outlook.com>
-
-This patch has been modified to be mvebu specific. The original patch 
-did not pass the bootloader cmdline on if no append-rootblock stanza 
-was found, resulting in blank cmdline and failure to boot.

-Subject: cpuidle: mvebu: indicate failure to enter deeper sleep states
-
-The cpuidle ->enter method expects the return value to be the sleep
-state we entered.  Returning negative numbers or other codes is not
-permissible since coupled CPU idle was merged.
-
-At least some of the mvebu_v7_cpu_suspend() implementations return the
-value from cpu_suspend(), which returns zero if the CPU vectors back
-into the kernel via cpu_resume() (the success case), or the non-zero
-return value of the suspend actor, or one (failure cases).
-
-We do not want to be returning the failure case value back to CPU idle
-as that indicates that we successfully entered one of the deeper idle
-states.  Always return zero instead, indicating that we slept for the
-shortest amount of time.

-Subject: [PATCH 2/7] drivers: mfd: Add a driver for IEI WT61P803 PUZZLE MCU
-
-Add a driver for the IEI WT61P803 PUZZLE microcontroller, used in some
-IEI Puzzle series devices. The microcontroller controls system power,
-temperature sensors, fans and LEDs.
-
-This driver implements the core functionality for device communication
-over the system serial (serdev bus). It handles MCU messages and the
-internal MCU properties. Some properties can be managed over sysfs.

-Subject: [PATCH 3/7] drivers: hwmon: Add the IEI WT61P803 PUZZLE HWMON driver
-
-Add the IEI WT61P803 PUZZLE HWMON driver, that handles the fan speed
-control via PWM, reading fan speed and reading on-board temperature
-sensors.
-
-The driver registers a HWMON device and a simple thermal cooling device to
-enable in-kernel fan management.
-
-This driver depends on the IEI WT61P803 PUZZLE MFD driver.

-Subject: [PATCH 4/7] drivers: leds: Add the IEI WT61P803 PUZZLE LED driver
-
-Add support for the IEI WT61P803 PUZZLE LED driver.
-Currently only the front panel power LED is supported,
-since it is the only LED on this board wired through the
-MCU.
-
-The LED is wired directly to the on-board MCU controller
-and is toggled using an MCU command.
-
-Support for more LEDs is going to be added in case more
-boards implement this microcontroller, as LEDs use many
-different GPIOs.
-
-This driver depends on the IEI WT61P803 PUZZLE MFD driver.

+Subject: [PATCH] clk: ipq8074: fix gcc_blsp1_ahb_clk properties
+
+All the voting enabled clocks does not support the enable
+from CBCR register. So, updated gcc_blsp1_ahb_clk enable
+register and mask to enable bit in APCS_CLOCK_BRANCH_ENA_VOTE.
+
+Also, the voting controlled clocks are shared among multiple
+components like APSS, RPM, NSS, TZ, etc. So, turning the
+voting off from APSS does not make the clock off if it has
+been voted from another component. Added the flag
+BRANCH_HALT_VOTED in order to skip checking the clock
+disable status.
+
+This change is referred from the below commits,
+1. 246b4fb3af9bd65d8af794aac2f0e7b1ed9cc2dd

+Subject: [PATCH 246/281] net:ipv6: Fix IPv6 user route change event calls
+
+These events should be called only when the route table is
+changed by the userspace. So, we should call them in the
+ioctl and the netlink message handler function.

+It looks like commit 0857d6f8c759 ("ipv6: When forwarding count rx stats
+on the orig netdev") tries to determine the right netdev to account the
+rx stats, but in this particular case it's failing and the netdev is
+NULL.
+
+Fallback to the previous method of determining the netdev interface (via
+skb->dev) to account the rx stats when the orig netdev can't be
+determined.
+
+Fixes: 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orig netdev")

-From: Jonas Karlman <jonas@kwiboo.se>
-Date: Wed, 20 Feb 2019 07:38:34 +0000
-Subject: [PATCH] mmc: core: set initial signal voltage on power off
-
-Some boards have SD card connectors where the power rail cannot be switched
-off by the driver. If the card has not been power cycled, it may still be
-using 1.8V signaling after a warm re-boot. Bootroms expecting 3.3V signaling
-will fail to boot from a UHS card that continue to use 1.8V signaling.
-
-Set initial signal voltage in mmc_power_off() to allow re-boot to function.
-
-This fixes re-boot with UHS cards on Asus Tinker Board (Rockchip RK3288),
-same issue have been seen on some Rockchip RK3399 boards.
-
-I am sending this as a RFC because I have no insights into SD/MMC subsystem,
-this change fix a re-boot issue on my boards and does not break emmc/sdio.
-Is this an acceptable workaround? Any advice is appreciated.

-which is now a year old.

-v2: Following up on Robin Murphy's comments, the NEO3 DTS is now
-standalone and no longer includes the nanopi R2S one. The lan_led and
-wan_len nodes have been removed, and the sys_led node has been renamed
-to status_led in accordance with the board schematics.

+Subject: [PATCH] firewall4: add fullcone support
+
+fullcone is drop-in replacement of masq for non-udp traffic
+
+add runtime fullcone rule check, disable it globally if fullcone expr is
+invalid
+
+defaults.fullcone is the global switch, while zone.fullcone4 and
+zone.fullcone6 are switches for IPv4 and IPv6 respectively, most
+IPv6 traffic do NOT need this FullCone NAT functionality.

+Subject: [PATCH] kconfig: abort configuration on unset symbol
+
+When a target configuration has unset Kconfig symbols, the build will
+fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
+
+In case OpenWrt is compiled without either of these preconditions, the
+build will succeed with the symbols in question being unset.
+
+Modify the kernel configuration in a way it fails on unset symbols
+regardless of the aforementioned preconditions.

+To: linux-mtd@lists.infradead.org

+    Richard Weinberger <richard@nod.at>,
+    Miquel Raynal <miquel.raynal@bootlin.com>,
+    David Woodhouse <dwmw2@infradead.org>
+
+Calling device_add_disk while holding mtd_table_mutex leads
+to deadlock in case part_bits!=0 as block partition parsers
+will try to open the newly created disks, trying to acquire
+mutex once again.
+Move device_add_disk to additional function called after
+add partitions of an MTD device have been added and locks
+have been released.

+Subject: [PATCH] drivers: mtd: parsers: add nvmem support to cmdlinepart
+
+Assuming cmdlinepart is only one level deep partition scheme and that
+static partition are also defined in DTS, we can assign an of_node for
+partition declared from bootargs. cmdlinepart have priority than
+fiexed-partition parser so in this specific case the parser doesn't
+assign an of_node. Fix this by searching a defined of_node using a
+similar fixed_partition parser and if a partition is found with the same
+label, check that it has the same offset and size and return the DT
+of_node to correctly use NVMEM cells.

+Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
+
+set-dscpmark is a method of storing the DSCP of an ip packet into
+conntrack mark.  In combination with a suitable tc filter action
+(act_ctinfo) DSCP values are able to be stored in the mark on egress and
+restored on ingress across links that otherwise alter or bleach DSCP.
+
+This is useful for qdiscs such as CAKE which are able to shape according
+to policies based on DSCP.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.
+
+x_tables CONNMARK set-dscpmark target solves the problem of storing the
+DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
+action to restore.
+
+The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
+32bit 'statemask'.  The dscp mask must be 6 contiguous bits and
+represents the area where the DSCP will be stored in the connmark.  The
+state mask is a minimum 1 bit length mask that must not overlap with the
+dscpmask.  It represents a flag which is set when the DSCP has been
+stored in the conntrack mark. This is useful to implement a 'one shot'
+iptables based classification where the 'complicated' iptables rules are
+only run once to classify the connection on initial (egress) packet and
+subsequent packets are all marked/restored with the same DSCP.  A state
+mask of zero disables the setting of a status bit/s.
+
+example syntax with a suitably modified iptables user space application:
+
+iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
+
+Would store the DSCP in the top 6 bits of the 32bit mark field, and use
+the LSB of the top byte as the 'DSCP has been stored' marker.

+
+To set the default size of the connection tracking hash table, a divider of
+16384 becomes inadequate for a router handling lots of connections. Divide by
+2048 instead, making the default size scale better with the available RAM.

+
+Adds support for AQR112 and AQR412 which is mostly based on existing code
+with the addition of code configuring the protocol on system side.
+This allows changing the system side protocol without having to deploy a
+different firmware on the PHY.

+Subject: [PATCH] net: phy: mediatek-ge: add LED configuration interface
+
+This adds a small hack similar to the one used for ar8xxx switches to
+read a reg:value map for configuring the LED configuration registers.
+
+This allows OpenWrt to write device-specific LED action as well as blink
+configurations. It is unlikely to be accepted upstream, as upstream
+plans on integrating their own framework for handling these LEDs.

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+		if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+			mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[    0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[    0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+This breaks control applications like WPA which maybe expecting to

+Subject: [PATCH] net: bridge: do not send arp replies if src and target hw
+ addr is the same
+
+There are broken devices in the wild that handle duplicate IP address
+detection by sending out ARP requests for the IP that they received from a
+DHCP server and refuse the address if they get a reply.
+When proxyarp is enabled, they would go into a loop of requesting an address
+and then NAKing it again.

+Subject: [PATCH] MIPS: Add barriers between dcache & icache flushes
+
+Index-based cache operations may be arbitrarily reordered by out of
+order CPUs. Thus code which writes back the dcache & then invalidates
+the icache using indexed cache ops must include a barrier between
+operating on the 2 caches in order to prevent the scenario in which:
+
+  - icache invalidation occurs.
+
+  - icache fetch occurs, due to speculation.
+
+  - dcache writeback occurs.
+
+If the above were allowed to happen then the icache would contain stale
+data. Forcing the dcache writeback to complete before the icache
+invalidation avoids this.

+
+This change allows OpenWRT to patch resulting kernel binary with
+external .dtb.
+
+That allows us to re-use exactky the same vmlinux on different boards
+given its ARC core configurations match (at least cache line sizes etc).
+
+""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
+.dtb right after it, keeping the string in place.

+Subject: [PATCH] mips: kernel: fix detect_memory_region() function
+
+1. Do not use memcmp() on unallocated memory, as the new introduced
+   fortify dynamic object size check[1] will report unexpected result.
+2. Use a fixed pattern instead of a random function pointer as the
+   magic value.
+3. Flip magic value and double check it.
+4. Enable this feature only for 32-bit CPUs. Currently, only ath79 and
+   ralink CPUs are using it.

+Subject: [PATCH] selftests/bpf: Improve portability of unprivileged tests
+
+The addition of general support for unprivileged tests in test_loader.c
+breaks building test_verifier on non-glibc (e.g. musl) systems, due to the
+inclusion of glibc extension '<error.h>' in 'unpriv_helpers.c'. However,
+the header is actually not needed, so remove it to restore building.

+Subject: [PATCH 5/9] nvmem: implement block NVMEM provider
+
+On embedded devices using an eMMC it is common that one or more partitions
+on the eMMC are used to store MAC addresses and Wi-Fi calibration EEPROM
+data. Allow referencing any block device or partition in Device Tree to
+allow e.g. Ethernet and Wi-Fi drivers accessing them via the NVMEM layer.

+Subject: kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.

+Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+  compatible = "mtd-concat";
+
+  devices = <&flash0 &flash1>;
+
+  partitions {
+    ...
+  };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix
+
+Macronix flash chips seem to consist of only one status register.
+These chips will not work with the "16-bit Write Status (01h) Command".
+Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
+
+Tested with MX25L6405D.
+
+Fixes: 39d1e3340c73 ("mtd: spi-nor: Fix clearing of QE bit on
+lock()/unlock()")

+Subject: [PATCH 1/2] block: add uImage.FIT subimage block driver
+
+Add a small block driver which exposes filesystem sub-images contained
+in U-Boot uImage.FIT images as block devices.
+
+The uImage.FIT image has to be stored directly on a block device or
+partition, MTD device or partition, or UBI volume.
+
+The driver is intended for systems using the U-Boot bootloader and
+uses the root device hint left by the bootloader (or the user) in
+the 'chosen' section of the device-tree.
+
+Example:
+/dts-v1/;
+/ {
+        chosen {
+                rootdisk = <&mmc0_part3>;
+        };
+};

+Subject: [PATCH] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+Subject: ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: [PATCH] of/of_net: write back netdev MAC-address to device-tree
+
+The label-mac logic relies on the mac-address property of a netdev
+devices of-node. However, the mac address can also be stored as a
+different property or read from e.g. an mtd device.
+
+Create this node when reading a mac-address from OF if it does not
+already exist and copy the mac-address used for the device to this
+property. This way, the MAC address can be accessed using procfs.

+Subject: [PATCH] netfilter: nf_tables: ignore -EOPNOTSUPP on flowtable device
+ offload setup
+
+On many embedded devices, it is common to configure flowtable offloading for
+a mix of different devices, some of which have hardware offload support and
+some of which don't.
+The current code limits the ability of user space to properly set up such a
+configuration by only allowing adding devices with hardware offload support to
+a offload-enabled flowtable.
+Given that offload-enabled flowtables also imply fallback to pure software
+offloading, this limitation makes little sense.
+Fix it by not bailing out when the offload setup returns -EOPNOTSUPP

+Subject: [PATCH] bridge: add knob for filtering rx/tx BPDU packets on a port
+
+Some devices (e.g. wireless APs) can't have devices behind them be part of
+a bridge topology with redundant links, due to address limitations.
+Additionally, broadcast traffic on these devices is somewhat expensive, due to
+the low data rate and wakeups of clients in powersave mode.
+This knob can be used to ensure that BPDU packets are never sent or forwarded
+to/from these devices

+links without reducing the SERDES speed.
+
+When operating without rate adapters the SERDES link will follow the
+ethernet speed.

+
+MAC drivers don't use SGMII in-band autonegotiation unless told to do so
+in device tree using 'managed = "in-band-status"'. When using MDIO to
+access a PHY, in-band-status is unneeded as we have link-status via
+MDIO. Switch off SGMII in-band autonegotiation using magic values.

+Subject: [PATCH] net: phy: realtek: make sure paged read is protected by mutex
+
+As we cannot rely on phy_read_paged function before the PHY is
+identified, the paged read in rtlgen_supports_2_5gbps needs to be open
+coded as it is being called by the match_phy_device function, ie. before
+.read_page and .write_page have been populated.
+
+Make sure it is also protected by the MDIO bus mutex and use
+rtl821x_write_page instead of 3 individually locked MDIO bus operations.

+While the hardware is capable of performing learning on the CPU port,
+it requires alot of additions to the bridge's forwarding path in order
+to handle multi-destination traffic correctly.
+
+Until that is in place, opt for the next best thing and let DSA sync
+the relevant addresses down to the hardware FDB.

+Subject: [PATCH] net vxlan: don't learn non-unicast L2 destinations
+
+This patch avoids learning non-unicast targets in the vxlan FDB.
+They are non-unicast and thus should be sent to the broadcast-IPv6
+instead of a unicast address.

+
+Add support for SBL state callback in MHI core.
+
+It is required for ath11k MHI devices in order to be able to set QRTR
+instance ID in the SBL state so that QRTR instance ID-s dont conflict in
+case of multiple PCI/MHI cards or AHB + PCI/MHI card.
+Setting QRTR instance ID is only possible in SBL state and there is
+currently no way to ensure that we are in that state, so provide a
+callback that the controller can trigger off.

+Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
+ subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[    1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[    1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[    1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[    1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[    0.157054] missing gpiochip .dev parent pointer
+[    0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").

+Subject: [PATCH 2/2] gpio: gpio-cascade: add generic GPIO cascade
+
+Adds support for building cascades of GPIO lines. That is, it allows
+setups when there is one upstream line and multiple cascaded lines, out
+of which one can be chosen at a time. The status of the upstream line
+can be conveyed to the selected cascaded line or, vice versa, the status
+of the cascaded line can be conveyed to the upstream line.
+
+A multiplexer is being used to select, which cascaded GPIO line is being
+used at any given time.
+
+At the moment only input direction is supported. In future it should be
+possible to add support for output direction, too.

+v7 -> v8:
+ - rearrange members in struct gpio_cascade
+ - cosmetic changes in file header and in one function declaration
+ - added Reviewed-by tags by Linus and Andy
+v6 -> v7:
+ - In Kconfig add info about module name
+ - adhere to new convention that allows lines longer than 80 chars
+ - use dev_probe_err with upstream gpio line too
+ - refactor for cleaner exit of probe function.
+v5 -> v6:
+ - In Kconfig, remove dependency to OF_GPIO and select only MULTIPLEXER
+ - refactor code preferring one-liners
+ - clean up prints, removing them from success-path.
+ - don't explicitly set gpio_chip.of_node as it's done in the GPIO library
+ - use devm_gpiochip_add_data instead of gpiochip_add
+v4 -> v5:
+ - renamed gpio-mux-input -> gpio-cascade. refactored code accordingly
+   here and there and changed to use new bindings and compatible string
+   - ambigious and vague 'pin' was rename to 'upstream_line'
+ - dropped Tested-by and Reviewed-by due to changes in bindings
+ - dropped Reported-by suggested by an automatic bot as it was not really
+   appropriate to begin with
+ - functionally it's the same as v4
+v3 -> v4:
+ - Changed author email
+ - Included Tested-by and Reviewed-by from Drew
+v2 -> v3:
+ - use managed device resources
+ - update Kconfig description
+v1 -> v2:
+ - removed .owner from platform_driver as per test bot's instruction
+ - added MODULE_AUTHOR, MODULE_DESCRIPTION, MODULE_LICENSE
+ - added gpio_mux_input_get_direction as it's recommended for all chips
+ - removed because this is input only chip: gpio_mux_input_set_value
+ - removed because they are not needed for input/output only chips:
+     gpio_mux_input_direction_input
+     gpio_mux_input_direction_output
+ - fixed typo in an error message
+ - added info message about successful registration
+ - removed can_sleep flag as this does not sleep while getting GPIO value
+   like I2C or SPI do
+ - Updated description in Kconfig

+Subject: [PATCH] PCI: aardvark: Make main irq_chip structure a static driver
+ structure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+We have already converted others irq_chip structures in this driver in
+this way, but we omitted this one because the .name member is
+dynamically created from device's name, and the name is displayed in
+sysfs, so changing it would break sysfs ABI.
+
+The rationale for changing the name (to "advk-INT") in spite of sysfs
+ABI, and thus allowing to convert to a static structure, is that after
+the other changes we made in this series, the IRQ chip is basically
+something different: it no logner generates ERR and PME interrupts (they
+are generated by emulated bridge's rp_irq_chip).

+of linux-imx (see link) in the sources for "Android Things" devkit.
+It is required to support CPU frequency scaling.
+
+Map the respective "cpu-supply" nodes of each core to sw1a of the PMIC.
+
+Enabling them causes cpufreq-dt, and imx-thermal drivers to probe
+successfully, and CPU frequency scaling to function.

+From: Imre Kaloz <kaloz@openwrt.org>
+Subject: init: add CONFIG_MANGLE_BOOTARGS and disable it by default
+
+Enabling this option renames the bootloader supplied root=
+and rootfstype= variables, which might have to be know but
+would break the automatisms OpenWrt uses.

+
+GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
+
+Setting irqchip.gicv2_force_probe=1 in bootargs results in:

+Using the adjusted CPU interface base and 8K size results in only the

+Subject: [PATCH] mediatek: mt7623: fix thermal zone
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raising the temperatures for passive and active trips. @VA1DER
+proposed at issue 9396 to remove passive trip. This commit relates to
+his suggestion.
+
+Without this patch. the CPU will be throttled all the way down to 98MHz
+if the temperature rises even a degree above the trip point, and it was
+further discovered that if the internal temperature of the device is
+above the first trip point temperature when it boots then it will start
+in a throttled state and even
+$ echo disabled > /sys/class/thermal/thermal_zone0/mode
+will have no effect.
+
+The patch increases the passive trip point and active cooling map. The
+throttling temperature will then be at 77°C and 82°C, which is still a
+low enough temperature for ARM devices to not be in the real danger
+zone, and gives some operational headroom.

+Subject: [PATCH] net: phy: mxl-gpy: don't use SGMII AN if using phylink
+
+MAC drivers using phylink expect SGMII in-band-status to be switched off
+when attached to a PHY. Make sure this is the case also for mxl-gpy which
+keeps SGMII in-band-status in case of SGMII interface mode is used.

+Subject: [PATCH net-next 2/2] net: ethernet: mtk_wed: move cpuboot in a
+ dedicated dts node
+
+Since the cpuboot memory region is not part of the RAM SoC, move cpuboot
+in a deidicated syscon node.
+This patch helps to keep backward-compatibility with older version of
+uboot codebase where we have a limit of 8 reserved-memory dts child
+nodes.
+Keep backward-compatibility with older dts version where cpuboot was
+defined as reserved-memory child node.

+Subject: [PATCH] clk: ipq8074: fix gcc_blsp1_ahb_clk properties
+
+All the voting enabled clocks does not support the enable
+from CBCR register. So, updated gcc_blsp1_ahb_clk enable
+register and mask to enable bit in APCS_CLOCK_BRANCH_ENA_VOTE.
+
+Also, the voting controlled clocks are shared among multiple
+components like APSS, RPM, NSS, TZ, etc. So, turning the
+voting off from APSS does not make the clock off if it has
+been voted from another component. Added the flag
+BRANCH_HALT_VOTED in order to skip checking the clock
+disable status.
+
+This change is referred from the below commits,
+1. 246b4fb3af9bd65d8af794aac2f0e7b1ed9cc2dd
+2. c8374157d5ae91d3b3e0d513d62808a798b32d3a

+
+These events should be called only when the route table is
+changed by the userspace. So, we should call them in the
+ioctl and the netlink message handler function.

+It looks like commit 0857d6f8c759 ("ipv6: When forwarding count rx stats
+on the orig netdev") tries to determine the right netdev to account the
+rx stats, but in this particular case it's failing and the netdev is
+NULL.
+
+Fallback to the previous method of determining the netdev interface (via
+skb->dev) to account the rx stats when the orig netdev can't be
+determined.
+
+Fixes: 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orig netdev")

+Subject: [PATCH] arm64: dts: rockchip: Add ethernet0 alias to the dts for
+ RK3566 boards
+
+Add ethernet0 alias to the board dts files for a few supported RK3566 boards
+that had it missing.  Also, remove the ethernet0 alias from one RK3566 SoM
+dtsi file, which doesn't enable the GMAC, and add the ethernet0 alias back to
+the dependent board dts files, which actually enable the GMAC.

+
+Use the SYS LED on the casing for showing system status.
+
+This patch is kept separate from the NanoPi R2S support patch, as i plan
+on submitting the device support upstream.

+Subject: arm64: dts: rockchip: disable UHS modes for NanoPi R4S
+
+The NanoPi R4S leaves the SD card in 1.8V signalling when rebooting
+while U-Boot requires the card to be in 3.3V mode.
+
+Remove UHS support from the SD controller so the card remains in 3.3V
+mode. This reduces transfer speeds but ensures a reboot whether from
+userspace or following a kernel panic is always working.

+Subject: [PATCH] firewall4: add fullcone support
+
+fullcone is drop-in replacement of masq for non-udp traffic
+
+add runtime fullcone rule check, disable it globally if fullcone expr is
+invalid
+
+defaults.fullcone is the global switch, while zone.fullcone4 and
+zone.fullcone6 are switches for IPv4 and IPv6 respectively, most
+IPv6 traffic do NOT need this FullCone NAT functionality.

+Subject: [PATCH] kconfig: abort configuration on unset symbol
+
+When a target configuration has unset Kconfig symbols, the build will
+fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
+
+In case OpenWrt is compiled without either of these preconditions, the
+build will succeed with the symbols in question being unset.
+
+Modify the kernel configuration in a way it fails on unset symbols
+regardless of the aforementioned preconditions.

+
+Calling device_add_disk while holding mtd_table_mutex leads
+to deadlock in case part_bits!=0 as block partition parsers
+will try to open the newly created disks, trying to acquire
+mutex once again.
+Move device_add_disk to additional function called after

+Subject: [PATCH] drivers: mtd: parsers: add nvmem support to cmdlinepart
+
+Assuming cmdlinepart is only one level deep partition scheme and that
+static partition are also defined in DTS, we can assign an of_node for
+partition declared from bootargs. cmdlinepart have priority than
+fiexed-partition parser so in this specific case the parser doesn't
+assign an of_node. Fix this by searching a defined of_node using a
+similar fixed_partition parser and if a partition is found with the same
+label, check that it has the same offset and size and return the DT
+of_node to correctly use NVMEM cells.

+Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
+
+set-dscpmark is a method of storing the DSCP of an ip packet into
+conntrack mark.  In combination with a suitable tc filter action
+(act_ctinfo) DSCP values are able to be stored in the mark on egress and
+restored on ingress across links that otherwise alter or bleach DSCP.
+
+This is useful for qdiscs such as CAKE which are able to shape according
+to policies based on DSCP.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.
+
+x_tables CONNMARK set-dscpmark target solves the problem of storing the
+DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
+action to restore.
+
+The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
+32bit 'statemask'.  The dscp mask must be 6 contiguous bits and
+represents the area where the DSCP will be stored in the connmark.  The
+state mask is a minimum 1 bit length mask that must not overlap with the
+dscpmask.  It represents a flag which is set when the DSCP has been
+stored in the conntrack mark. This is useful to implement a 'one shot'
+iptables based classification where the 'complicated' iptables rules are
+only run once to classify the connection on initial (egress) packet and
+subsequent packets are all marked/restored with the same DSCP.  A state
+mask of zero disables the setting of a status bit/s.
+
+example syntax with a suitably modified iptables user space application:
+
+iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
+
+Would store the DSCP in the top 6 bits of the 32bit mark field, and use
+the LSB of the top byte as the 'DSCP has been stored' marker.
+
+|----0xFC----conntrack mark----000000---|
+| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
+| DSCP       | unused | flag  |unused   |
+|-----------------------0x01---000000---|

+|-------------|
+
+an identically configured tc action to restore looks like:

+
+To set the default size of the connection tracking hash table, a divider of
+16384 becomes inadequate for a router handling lots of connections. Divide by

+
+Adds support for AQR112 and AQR412 which is mostly based on existing code
+with the addition of code configuring the protocol on system side.
+This allows changing the system side protocol without having to deploy a
+different firmware on the PHY.

+Subject: [PATCH] net: phy: mediatek-ge: add LED configuration interface
+
+This adds a small hack similar to the one used for ar8xxx switches to
+read a reg:value map for configuring the LED configuration registers.
+
+This allows OpenWrt to write device-specific LED action as well as blink
+configurations. It is unlikely to be accepted upstream, as upstream
+plans on integrating their own framework for handling these LEDs.

+If the subflow is considered as "staled", it is better to avoid it to

+Subject: [PATCH 09/28] mptcp: annotate data-races around
+ subflow->fully_established
+
+We introduce the same handling for potential data races with the
+'fully_established' flag in subflow as previously done for
+msk->fully_established.
+
+Additionally, we make a crucial change: convert the subflow's
+'fully_established' from 'bit_field' to 'bool' type. This is
+necessary because methods for avoiding data races don't work well
+with 'bit_field'. Specifically, the 'READ_ONCE' needs to know
+the size of the variable being accessed, which is not supported in
+'bit_field'. Also, 'test_bit' expect the address of 'bit_field'.

+
+The MPTCP path manager event handler mptcp_pm_connection_closed
+interface has been added in the commit 1b1c7a0ef7f3 ("mptcp: Add path
+manager interface") but it was an empty function from then on.
+
+With such name, it sounds good to invoke mptcp_event with the
+MPTCP_EVENT_CLOSED event type from it. It also removes a bit of
+duplicated code.

+Subject: [PATCH 14/28] bpf: Add bpf_mptcp_sched_ops
+
+This patch implements a new struct bpf_struct_ops: bpf_mptcp_sched_ops.
+Register and unregister the bpf scheduler in .reg and .unreg.
+
+Add write access for the scheduled flag of struct mptcp_subflow_context
+in .btf_struct_access.
+
+This MPTCP BPF scheduler implementation is similar to BPF TCP CC. And
+net/ipv4/bpf_tcp_ca.c is a frame of reference for this patch.

+Subject: [PATCH 16/28] selftests/bpf: Add mptcp subflow example
+
+Move Nicolas' patch into bpf selftests directory. This example adds a
+different mark (SO_MARK) on each subflow, and changes the TCP CC only on
+the first subflow.
+
+From the userspace, an application can do a setsockopt() on an MPTCP
+socket, and typically the same value will be propagated to all subflows
+(paths). If someone wants to have different values per subflow, the
+recommended way is to use BPF. So it is good to add such example here,
+and make sure there is no regressions.
+
+This example shows how it is possible to:
+
+    Identify the parent msk of an MPTCP subflow.
+    Put different sockopt for each subflow of a same MPTCP connection.
+
+Here especially, two different behaviours are implemented:
+
+    A socket mark (SOL_SOCKET SO_MARK) is put on each subflow of a same
+    MPTCP connection. The order of creation of the current subflow defines
+    its mark. The TCP CC algorithm of the very first subflow of an MPTCP
+    connection is set to "reno".
+
+This is just to show it is possible to identify an MPTCP connection, and
+set socket options, from different SOL levels, per subflow. It is easy
+to verify with 'ss' that these modifications have been applied
+correctly. That's what the next patch is going to do.
+
+Nicolas' code comes from:
+
+    commit 4d120186e4d6 ("bpf:examples: update mptcp_set_mark_kern.c")
+
+from the MPTCP repo https://github.com/multipath-tcp/mptcp_net-next (the
+"scripts" branch), and it has been adapted by Geliang.

+Subject: [PATCH 17/28] selftests/bpf: Add getsockopt to inspect mptcp subflow
+
+This patch adds a "cgroup/getsockopt" way to inspect the subflows of an
+mptcp socket. That will be used by the next commit to verify the socket
+options set on each subflow.
+
+This extra "cgroup/getsockopt" prog walks the msk->conn_list and use
+bpf_core_cast to cast a pointer for readonly. It allows to inspect all
+the fields of a structure.
+
+mptcp_subflow_tcp_sock(), mptcp_for_each_stubflow() and other helpers
+related to list_entry have been added into a new progs/mptcp_bpf.h file.

+Subject: [PATCH 18/28] selftests/bpf: Add mptcp subflow subtest
+
+This patch adds a subtest named test_subflow to load and verify the newly
+added mptcp subflow example in test_mptcp. Add a helper endpoint_init()
+to add a new subflow endpoint. Add another helper ss_search() to verify the
+fwmark and congestion values set by mptcp_subflow prog using setsockopts.

+Subject: [PATCH 19/28] selftests/bpf: Add bpf scheduler test
+
+This patch extends the MPTCP test base to support MPTCP packet scheduler
+tests. Add a new test to use the default in-kernel scheduler.
+
+In the new helper sched_init(), add two veth net devices to simulate the
+multiple addresses case. Use 'ip mptcp endpoint' command to add the new
+endpoint ADDR_2 to PM netlink. Use sysctl to set net.mptcp.scheduler to
+use the given sched.
+
+Invoke start_mptcp_server() to start the server on ADDR_1, and invoke
+connect_to_fd() to connect with the server from the client. Then invoke
+send_data() to send data.
+
+Some code in send_data() is from prog_tests/bpf_tcp_ca.c.
+
+Add time metrics for BPF tests to compare the performance of each
+schedulers. Run prog_tests with '-v' option can print out the running
+time of each test.
+
+Use the new helper has_bytes_sent() to check the bytes_sent filed of 'ss'
+output after send_data() to make sure no data has been sent on ADDR_2.
+All data has been sent on the first subflow.
+
+Invoke the new helper sched_cleanup() to set back net.mptcp.scheduler to
+default, flush all mptcp endpoints, and delete the veth net devices.

+Subject: [PATCH 20/28] selftests/bpf: Add bpf_first scheduler & test
+
+This patch implements the simplest MPTCP scheduler, named bpf_first,
+which always picks the first subflow to send data. It's a sample of
+MPTCP BPF scheduler implementations.
+
+This patch defines MPTCP_SCHED_TEST macro, a template for all scheduler
+tests. Every scheduler is identified by argument name, and use sysctl
+to set net.mptcp.scheduler as "bpf_name" to use this sched. Add two
+veth net devices to simulate the multiple addresses case. Use 'ip mptcp
+endpoint' command to add the new endpoint ADDR2 to PM netlink. Arguments
+addr1/add2 means whether the data has been sent on the first/second
+subflow or not. Send data and check bytes_sent of 'ss' output after it
+using send_data_and_verify().
+
+Using MPTCP_SCHED_TEST macro to add a new test for this bpf_first
+scheduler, the arguments "1 0" means data has been only sent on the
+first subflow ADDR1. Run this test by RUN_MPTCP_TEST macro.

+Subject: [PATCH 24/28] bpf: Export more bpf_burst related functions
+
+sk_stream_memory_free() and tcp_rtx_and_write_queues_empty() are needed
+to export into the BPF context for bpf_burst scheduler. But these two
+functions are inline ones. So this patch added two wrappers for them,
+and export the wrappers in the BPF context.
+
+Add more bpf_burst related functions into bpf_mptcp_sched_kfunc_set to make
+sure these helpers can be accessed from the BPF context.

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+		if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+			mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[    0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[    0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+ addr is the same
+
+There are broken devices in the wild that handle duplicate IP address
+detection by sending out ARP requests for the IP that they received from a
+DHCP server and refuse the address if they get a reply.
+When proxyarp is enabled, they would go into a loop of requesting an address
+and then NAKing it again.

+Subject: [PATCH] MIPS: Add barriers between dcache & icache flushes
+
+Index-based cache operations may be arbitrarily reordered by out of
+order CPUs. Thus code which writes back the dcache & then invalidates
+the icache using indexed cache ops must include a barrier between
+operating on the 2 caches in order to prevent the scenario in which:
+
+  - icache invalidation occurs.
+
+  - icache fetch occurs, due to speculation.
+
+  - dcache writeback occurs.
+
+If the above were allowed to happen then the icache would contain stale
+data. Forcing the dcache writeback to complete before the icache
+invalidation avoids this.

+
+This change allows OpenWRT to patch resulting kernel binary with
+external .dtb.
+
+That allows us to re-use exactky the same vmlinux on different boards
+given its ARC core configurations match (at least cache line sizes etc).
+
+""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
+.dtb right after it, keeping the string in place.

+From: Alexey Brodkin <abrodkin@synopsys.com>
+Subject: arc: enable unaligned access in kernel mode
+
+This enables misaligned access handling even in kernel mode.
+Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
+here and there and to cope with that without fixing stuff in the drivers
+we're just gracefully handling it on ARC.

+Subject: [PATCH] mips: kernel: fix detect_memory_region() function
+
+1. Do not use memcmp() on unallocated memory, as the new introduced
+   fortify dynamic object size check[1] will report unexpected result.
+2. Use a fixed pattern instead of a random function pointer as the
+   magic value.
+3. Flip magic value and double check it.
+4. Enable this feature only for 32-bit CPUs. Currently, only ath79 and
+   ralink CPUs are using it.

+Subject: [PATCH] selftests/bpf: Improve portability of unprivileged tests
+
+The addition of general support for unprivileged tests in test_loader.c
+breaks building test_verifier on non-glibc (e.g. musl) systems, due to the
+inclusion of glibc extension '<error.h>' in 'unpriv_helpers.c'. However,
+the header is actually not needed, so remove it to restore building.

++	  register MTD 'partitions' corresponding to each image detected,
++	  enable this option.
++

+Subject: [PATCH 5/9] nvmem: implement block NVMEM provider
+
+On embedded devices using an eMMC it is common that one or more partitions
+on the eMMC are used to store MAC addresses and Wi-Fi calibration EEPROM
+data. Allow referencing any block device or partition in Device Tree to
+allow e.g. Ethernet and Wi-Fi drivers accessing them via the NVMEM layer.

+Subject: kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.

+Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+  compatible = "mtd-concat";
+
+  devices = <&flash0 &flash1>;
+
+  partitions {
+    ...
+  };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix
+
+Macronix flash chips seem to consist of only one status register.
+These chips will not work with the "16-bit Write Status (01h) Command".
+Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
+
+Tested with MX25L6405D.
+
+Fixes: 39d1e3340c73 ("mtd: spi-nor: Fix clearing of QE bit on
+lock()/unlock()")

+Subject: [PATCH 1/2] block: add uImage.FIT subimage block driver
+
+Add a small block driver which exposes filesystem sub-images contained
+in U-Boot uImage.FIT images as block devices.
+
+The uImage.FIT image has to be stored directly on a block device or
+partition, MTD device or partition, or UBI volume.
+
+The driver is intended for systems using the U-Boot bootloader and
+uses the root device hint left by the bootloader (or the user) in
+the 'chosen' section of the device-tree.
+
+Example:
+/dts-v1/;
+/ {
+        chosen {
+                rootdisk = <&mmc0_part3>;
+        };
+};

+Subject: [PATCH] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+Subject: ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: [PATCH] of/of_net: write back netdev MAC-address to device-tree
+
+The label-mac logic relies on the mac-address property of a netdev
+devices of-node. However, the mac address can also be stored as a
+different property or read from e.g. an mtd device.
+
+Create this node when reading a mac-address from OF if it does not
+already exist and copy the mac-address used for the device to this
+property. This way, the MAC address can be accessed using procfs.

+Subject: [PATCH] netfilter: nf_tables: ignore -EOPNOTSUPP on flowtable device
+ offload setup
+
+On many embedded devices, it is common to configure flowtable offloading for
+a mix of different devices, some of which have hardware offload support and
+some of which don't.
+The current code limits the ability of user space to properly set up such a
+configuration by only allowing adding devices with hardware offload support to
+a offload-enabled flowtable.
+Given that offload-enabled flowtables also imply fallback to pure software
+offloading, this limitation makes little sense.
+Fix it by not bailing out when the offload setup returns -EOPNOTSUPP

+Subject: [PATCH] bridge: add knob for filtering rx/tx BPDU packets on a port
+
+Some devices (e.g. wireless APs) can't have devices behind them be part of
+a bridge topology with redundant links, due to address limitations.
+Additionally, broadcast traffic on these devices is somewhat expensive, due to
+the low data rate and wakeups of clients in powersave mode.
+This knob can be used to ensure that BPDU packets are never sent or forwarded
+to/from these devices

+- SGMII
+- 2500base-x
+- HiSGMII
+
+Further it supports rate adaption on SERDES links to allow
+slow ethernet speeds (10/100/1000mbit) to work on 2500base-x/HiSGMII
+links without reducing the SERDES speed.
+
+When operating without rate adapters the SERDES link will follow the

+Subject: [PATCH 2/2] net: phy: realtek: disable SGMII in-band AN for 2.5G PHYs
+
+MAC drivers don't use SGMII in-band autonegotiation unless told to do so
+in device tree using 'managed = "in-band-status"'. When using MDIO to
+access a PHY, in-band-status is unneeded as we have link-status via
+MDIO. Switch off SGMII in-band autonegotiation using magic values.

+Subject: [PATCH] net: phy: realtek: make sure paged read is protected by mutex
+
+As we cannot rely on phy_read_paged function before the PHY is
+identified, the paged read in rtlgen_supports_2_5gbps needs to be open
+coded as it is being called by the match_phy_device function, ie. before
+.read_page and .write_page have been populated.
+
+Make sure it is also protected by the MDIO bus mutex and use
+rtl821x_write_page instead of 3 individually locked MDIO bus operations.

+While the hardware is capable of performing learning on the CPU port,
+it requires alot of additions to the bridge's forwarding path in order
+to handle multi-destination traffic correctly.
+
+Until that is in place, opt for the next best thing and let DSA sync

+
+Add support for SBL state callback in MHI core.
+
+It is required for ath11k MHI devices in order to be able to set QRTR
+instance ID in the SBL state so that QRTR instance ID-s dont conflict in
+case of multiple PCI/MHI cards or AHB + PCI/MHI card.
+Setting QRTR instance ID is only possible in SBL state and there is
+currently no way to ensure that we are in that state, so provide a
+callback that the controller can trigger off.

+Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
+ subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[    1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[    1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[    1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[    1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[    0.157054] missing gpiochip .dev parent pointer
+[    0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").

+Subject: [PATCH 2/2] gpio: gpio-cascade: add generic GPIO cascade
+
+Adds support for building cascades of GPIO lines. That is, it allows
+setups when there is one upstream line and multiple cascaded lines, out
+of which one can be chosen at a time. The status of the upstream line
+can be conveyed to the selected cascaded line or, vice versa, the status
+of the cascaded line can be conveyed to the upstream line.
+
+A multiplexer is being used to select, which cascaded GPIO line is being
+used at any given time.
+
+At the moment only input direction is supported. In future it should be
+possible to add support for output direction, too.

+v7 -> v8:
+ - rearrange members in struct gpio_cascade
+ - cosmetic changes in file header and in one function declaration
+ - added Reviewed-by tags by Linus and Andy
+v6 -> v7:
+ - In Kconfig add info about module name
+ - adhere to new convention that allows lines longer than 80 chars
+ - use dev_probe_err with upstream gpio line too
+ - refactor for cleaner exit of probe function.
+v5 -> v6:
+ - In Kconfig, remove dependency to OF_GPIO and select only MULTIPLEXER
+ - refactor code preferring one-liners
+ - clean up prints, removing them from success-path.
+ - don't explicitly set gpio_chip.of_node as it's done in the GPIO library
+ - use devm_gpiochip_add_data instead of gpiochip_add
+v4 -> v5:
+ - renamed gpio-mux-input -> gpio-cascade. refactored code accordingly
+   here and there and changed to use new bindings and compatible string
+   - ambigious and vague 'pin' was rename to 'upstream_line'
+ - dropped Tested-by and Reviewed-by due to changes in bindings
+ - dropped Reported-by suggested by an automatic bot as it was not really
+   appropriate to begin with
+ - functionally it's the same as v4
+v3 -> v4:
+ - Changed author email
+ - Included Tested-by and Reviewed-by from Drew
+v2 -> v3:
+ - use managed device resources
+ - update Kconfig description
+v1 -> v2:
+ - removed .owner from platform_driver as per test bot's instruction
+ - added MODULE_AUTHOR, MODULE_DESCRIPTION, MODULE_LICENSE
+ - added gpio_mux_input_get_direction as it's recommended for all chips
+ - removed because this is input only chip: gpio_mux_input_set_value
+ - removed because they are not needed for input/output only chips:
+     gpio_mux_input_direction_input
+     gpio_mux_input_direction_output
+ - fixed typo in an error message
+ - added info message about successful registration
+ - removed can_sleep flag as this does not sleep while getting GPIO value
+   like I2C or SPI do
+ - Updated description in Kconfig

+Subject: [PATCH] PCI: aardvark: Make main irq_chip structure a static driver
+ structure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+We have already converted others irq_chip structures in this driver in
+this way, but we omitted this one because the .name member is
+dynamically created from device's name, and the name is displayed in
+sysfs, so changing it would break sysfs ABI.
+
+The rationale for changing the name (to "advk-INT") in spite of sysfs
+ABI, and thus allowing to convert to a static structure, is that after
+the other changes we made in this series, the IRQ chip is basically
+something different: it no logner generates ERR and PME interrupts (they
+are generated by emulated bridge's rp_irq_chip).

+Subject: [PATCH] ARM: dts: nxp: imx7d-pico: add cpu-supply nodes
+
+The PICO-IMX7D SoM has the usual power supply configuration using
+output sw1a of PF3000 PMIC, which was defined in downstream derivative
+of linux-imx (see link) in the sources for "Android Things" devkit.
+It is required to support CPU frequency scaling.
+
+Map the respective "cpu-supply" nodes of each core to sw1a of the PMIC.
+
+Enabling them causes cpufreq-dt, and imx-thermal drivers to probe
+successfully, and CPU frequency scaling to function.

+From: Imre Kaloz <kaloz@openwrt.org>
+Subject: init: add CONFIG_MANGLE_BOOTARGS and disable it by default
+
+Enabling this option renames the bootloader supplied root=
+and rootfstype= variables, which might have to be know but
+would break the automatisms OpenWrt uses.

+Subject: [PATCH] firewall4: add fullcone support
+
+fullcone is drop-in replacement of masq for non-udp traffic
+
+add runtime fullcone rule check, disable it globally if fullcone expr is
+invalid
+
+defaults.fullcone is the global switch, while zone.fullcone4 and
+zone.fullcone6 are switches for IPv4 and IPv6 respectively, most
+IPv6 traffic do NOT need this FullCone NAT functionality.

+

+Subject: [PATCH 016/697] drm/atomic-helpers: remove legacy_cursor_update hacks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The stuff never really worked, and leads to lots of fun because it
+out-of-order frees atomic states. Which upsets KASAN, among other
+things.
+
+For async updates we now have a more solid solution with the
+->atomic_async_check and ->atomic_async_commit hooks. Support for that
+for msm and vc4 landed. nouveau and i915 have their own commit
+routines, doing something similar.
+
+For everyone else it's probably better to remove the use-after-free
+bug, and encourage folks to use the async support instead. The
+affected drivers which register a legacy cursor plane and don't either
+use the new async stuff or their own commit routine are: amdgpu,
+atmel, mediatek, qxl, rockchip, sti, sun4i, tegra, virtio, and vmwgfx.
+
+Inspired by an amdgpu bug report.
+
+v2: Drop RFC, I think with amdgpu converted over to use
+atomic_async_check/commit done in

+
+    drm/amd/display: Add fast path for cursor plane updates
+
+we don't have any driver anymore where we have userspace expecting
+solid legacy cursor support _and_ they are using the atomic helpers in
+their fully glory. So we can retire this.
+
+v3: Paper over msm and i915 regression. The complete_all is the only
+thing missing afaict.
+
+v4: Rebased on recent kernel, added extra link for vc4 bug.

+ planes.
+
+Margins may be implemented by scaling the planes, but as there
+is no way of intercepting the set_property for a standard property,
+and all planes are checked in drm_atomic_check_only before the
+connectors, there's now way to add the planes into the state
+from the driver.
+
+If the margin properties change, add all corresponding planes to
+the state.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add the bare minimum needed to boot BCM2708 from a Device Tree.

+BCM2708: DT: change 'axi' nodename to 'soc'
+
+Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
+The VC4 bootloader fills in certain properties in the 'axi' subtree,
+but since this is part of an upstreaming effort, the name is changed.

+
+BCM2708_DT: Correct length of the peripheral space
+
+Use dts-dirs feature for overlays.
+
+The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
+
+Using this fixes the install_dtbs target, which previously did not install the overlays.
+
+BCM270X_DT: configure I2S DMA channels

+
+BCM270X_DT: switch to bcm2835-i2s
+
+I2S soundcard drivers with proper devicetree support (i.e. not linking
+to the cpu_dai/platform via name but to cpu/platform via of_node)
+will work out of the box without any modifications.
+
+When the kernel is compiled without devicetree support the platform
+code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
+will link to it via name, as before.

+SDIO-overlay: add poll_once-boolean parameter

+
+BCM270X_DT: Make mmc overlay compatible with current firmware
+
+The original DT overlay logic followed a merge-then-patch procedure,
+i.e. parameters are applied to the loaded overlay before the overlay
+is merged into the base DTB. This sequence has been changed to
+patch-then-merge, in order to support parameterised node names, and
+to protect against bad overlays. As a result, overrides (parameters)
+must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
+
+mmc-overlay.dts (that switches back to the original mmc sdcard
+driver) is the only overlay violating that rule, and this patch
+fixes it.
+
+bcm270x_dt: Use the sdhost MMC controller by default
+
+The "mmc" overlay reverts to using the other controller.
+
+squash: Add cprman to dt
+
+BCM270X_DT: Use clk_core for I2C interfaces
+
+BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
+
+The mainline Device Tree files are quite close to downstream now.
+Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
+for our dts files.
+
+Mainline dts files are based on these files:
+
+          bcm2835-rpi.dtsi
+  bcm2835.dtsi    bcm2836.dtsi
+          bcm283x.dtsi
+
+Current downstream are based on these:
+
+  bcm2708.dtsi    bcm2709.dtsi    bcm2710.dtsi
+             bcm2708_common.dtsi
+
+This patch introduces this dependency:
+
+  bcm2708.dtsi    bcm2709.dtsi
+          bcm2708-rpi.dtsi
+          bcm270x.dtsi
+  bcm2835.dtsi    bcm2836.dtsi
+          bcm283x.dtsi
+
+And:
+          bcm2710.dtsi
+          bcm2708-rpi.dtsi
+          bcm270x.dtsi
+          bcm283x.dtsi
+
+bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
+bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
+
+Other changes:
+- The led node has moved from /soc/leds to /leds. This is not a problem
+  since the label is used to reference it.
+- The clk_osc reg property changes from 6 to 3.
+- The gpu nodes has their interrupt property set in the base file.
+- the clocks label does not point to the /clocks node anymore, but
+  points to the cprman node. This is not a problem since the overlays
+  that use the clock node refer to it directly: target-path = "/clocks";
+- some nodes now have 2 labels since mainline and downstream differs in
+  this respect: cprman/clocks, spi0/spi, gpu/vc4.
+- some nodes doesn't have an explicit status = "okay" since they're not
+  disabled in the base file: watchdog and random.
+- gpiomem doesn't need an explicit status = "okay".
+- bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
+  it's now set directly in that file.
+- bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
+- Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

+BCM270X_DT: Don't generate "linux,phandle" props
+
+The EPAPR standard says to use "phandle" properties to store phandles,
+rather than the deprecated "linux,phandle" version. By default, dtc
+generates both, but adding "-H epapr" causes it to only generate
+"phandle"s, saving some space and clutter.

+
+MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The
+midi-uart0 overlay configures uart0 (ttyAMA0) to use a fake clock
+so that requesting 38.4kbaud actually gets 31.25kbaud.

+kbuild: Silence unavoidable dtc overlay warnings
+
+Much effort has been put into finding ways to avoid warnings from dtc
+about overlays, usually to do with the presence of #address-cells and

++Introduction
++============
++
++This directory contains Device Tree overlays. Device Tree makes it possible
++to support many hardware configurations with a single kernel and without the
++need to explicitly load or blacklist kernel modules. Note that this isn't a
++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
++are still configured by the board support code, but the intention is to
++eventually reach that goal.
++
++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
++default, the Raspberry Pi kernel boots with device tree enabled. You can
++completely disable DT usage (for now) by adding:
++
++    device_tree=
++
++to your config.txt, which should cause your Pi to revert to the old way of
++doing things after a reboot.
++
++In /boot you will find a .dtb for each base platform. This describes the
++hardware that is part of the Raspberry Pi board. The loader (start.elf and its
++siblings) selects the .dtb file appropriate for the platform by name, and reads
++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
++are disabled, but they can be enabled using Device Tree parameters:
++
++    dtparam=i2c=on,i2s=on,spi=on
++
++However, this shouldn't be necessary in many use cases because loading an
++overlay that requires one of those interfaces will cause it to be enabled
++automatically, and it is advisable to only enable interfaces if they are
++needed.
++
++Configuring additional, optional hardware is done using Device Tree overlays
++(see below).
++
++GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
++not the physical pin numbers.
++
++raspi-config
++============
++
++The Advanced Options section of the raspi-config utility can enable and disable
++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
++is possible to both enable an interface and blacklist the driver, if for some
++reason you should want to defer the loading.
++
++Modules
++=======
++
++As well as describing the hardware, Device Tree also gives enough information
++to allow suitable driver modules to be located and loaded, with the corollary
++that unneeded modules are not loaded. As a result it should be possible to
++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
++have its contents deleted (or commented out).
++
++Using Overlays
++==============
++
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++    modprobe i2c-bcm2835
++    modprobe rtc-ds1307
++    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
++
++With DT enabled, this becomes a line in config.txt:
++
++    dtoverlay=i2c-rtc,ds1307
++
++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++    dtoverlay=i2c-rtc,ds1307,addr=0x68
++
++Parameters usually have default values, although certain parameters are
++mandatory. See the list of overlays below for a description of the parameters
++and their defaults.
++
++Making new Overlays based on existing Overlays
++==============================================
++
++Recent overlays have been designed in a more general way, so that they can be
++adapted to hardware by changing their parameters. When you have additional
++hardware with more than one device of a kind, you end up using the same overlay
++multiple times with other parameters, e.g.
++
++    # 2 CAN FD interfaces on spi but with different pins
++    dtoverlay=mcp251xfd,spi0-0,interrupt=25
++    dtoverlay=mcp251xfd,spi0-1,interrupt=24
++
++    # a realtime clock on i2c
++    dtoverlay=i2c-rtc,pcf85063
++
++While this approach does work, it requires knowledge about the hardware design.
++It is more feasible to simplify things for the end user by providing a single
++overlay as it is done the traditional way.
++
++A new overlay can be generated by using ovmerge utility.
++https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge
++
++To generate an overlay for the above configuration we pass the configuration
++to ovmerge and add the -c flag.
++
++    ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \
++               mcp251xfd-overlay.dts,spi0-1,interrupt=24 \
++               i2c-rtc-overlay.dts,pcf85063 \
++    >> merged-overlay.dts
++
++The -c option writes the command above as a comment into the overlay as
++a marker that this overlay is generated and how it was generated.
++After compiling the overlay it can be loaded in a single line.
++
++    dtoverlay=merged
++
++It does the same as the original configuration but without parameters.
++
++The Overlay and Parameter Reference

++Name:   fbtft
++Info:   Overlay for SPI-connected displays using the fbtft drivers.
++
++        This overlay seeks to replace the functionality provided by fbtft_device
++        which is now gone from the kernel.
++
++        Most displays from fbtft_device have been ported over.
++        Example:
++          dtoverlay=fbtft,spi0-0,rpi-display,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
++
++        It is also possible to specify the controller (this will use the default
++        init sequence in the driver).
++        Example:
++          dtoverlay=fbtft,spi0-0,ili9341,bgr,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
++
++        For devices on spi1 or spi2, the interfaces should be enabled
++        with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
++
++        The following features of fbtft_device have not been ported over:
++        - parallel bus is not supported
++        - the init property which overrides the controller initialization
++          sequence is not supported as a parameter due to memory limitations in
++          the bootloader responsible for applying the overlay.
++

++Name:   gpio-led
++Info:   This is a generic overlay for activating LEDs (or any other component)
++        by a GPIO pin. Multiple LEDs can be set up using multiple calls to the
++        overlay. While there are many existing methods to activate LEDs on the
++        RPi, this method offers some advantages:
++        1) Does not require any userspace programs.
++        2) LEDs can be connected to the kernel's led-trigger framework,
++           and drive the LED based on triggers such as cpu load, heartbeat,
++           kernel panic, key input, timers and others.
++        3) LED can be tied to the input state of another GPIO pin.
++        4) The LED is setup early during the kernel boot process (useful
++           for cpu/heartbeat/panic triggers).
++
++        Typical electrical connection is:
++           RPI-GPIO.19  ->  LED  -> 300ohm resister  -> RPI-GND
++        The GPIO pin number can be changed with the 'gpio=' parameter.
++
++        To control an LED from userspace, write a 0 or 1 value:
++           echo 1 > /sys/class/leds/myled1/brightness
++        The 'myled1' name can be changed with the 'label=' parameter.
++
++        To connect the LED to a kernel trigger from userspace:
++           echo cpu > /sys/class/leds/myled1/trigger
++           echo heartbeat > /sys/class/leds/myled1/trigger
++           echo none > /sys/class/leds/myled1/trigger
++        To connect the LED to GPIO.26 pin (physical pin 37):
++           echo gpio > /sys/class/leds/myled1/trigger
++           echo 26 > /sys/class/leds/myled1/gpio
++        Available triggers:
++           cat /sys/class/leds/myled1/trigger

++                                /sys/class/leds/<label> . Default 'myled1'.
++        trigger                 Set the led-trigger to connect to this LED.
++                                default 'none' (LED is user-controlled).
++                                Some possible triggers:
++                                 cpu - CPU load (all CPUs)
++                                 cpu0 - CPU load of first CPU.
++                                 mmc - disk activity (all disks)
++                                 panic - turn on on kernel panic
++                                 heartbeat - indicate system health
++                                 gpio - connect to a GPIO input pin (note:
++                                        currently the GPIO PIN can not be set
++                                        using overlay parameters, must be

++        active_low              Set to 1 to turn invert the LED control
++                                (writing 0 to /sys/class/leds/XXX/brightness
++                                will turn on the GPIO/LED). Default '0'.

++Name:   gpio-no-bank0-irq
++Info:   Use this overlay to disable GPIO interrupts for GPIOs in bank 0 (0-27),
++        which can be useful for UIO drivers.
++        N.B. Using this overlay will trigger a kernel WARN during booting, but
++        this can safely be ignored - the system should work as expected.
++Load:   dtoverlay=gpio-no-bank0-irq
++Params: <None>
++
++
++Name:   gpio-no-irq
++Info:   Use this overlay to disable all GPIO interrupts, which can be useful
++        for user-space GPIO edge detection systems.
++Load:   dtoverlay=gpio-no-irq
++Params: <None>
++
++
++Name:   gpio-poweroff
++Info:   Drives a GPIO high or low on poweroff (including halt). Using this
++        overlay interferes with the normal power-down sequence, preventing the
++        kernel from resetting the SoC (a necessary step in a normal power-off
++        or reboot). This also disables the ability to trigger a boot by driving
++        GPIO3 low.
++
++        The GPIO starts in an inactive state. At poweroff time it is driven
++        active for 100ms, then inactive for 100ms, then active again. It is
++        safe to remove the power at any point after the initial activation of
++        the GPIO.
++
++        Users of this overlay are required to provide an external mechanism to

++Name:   gpio-shutdown
++Info:   Initiates a shutdown when GPIO pin changes. The given GPIO pin
++        is configured as an input key that generates KEY_POWER events.
++
++        This event is handled by systemd-logind by initiating a
++        shutdown. Systemd versions older than 225 need an udev rule
++        enable listening to the input device:
++
++                ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
++                        SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
++                        ATTRS{keys}=="116", TAG+="power-switch"
++
++        Alternatively this event can be handled also on systems without
++        systemd, just by traditional SysV init daemon. KEY_POWER event
++        (keycode 116) needs to be mapped to KeyboardSignal on console
++        and then kb::kbrequest inittab action which is triggered by
++        KeyboardSignal from console can be configured to issue system
++        shutdown. Steps for this configuration are:
++
++            Add following lines to the /etc/console-setup/remap.inc file:
++
++                # Key Power as special keypress
++                keycode 116 = KeyboardSignal
++
++            Then add following lines to /etc/inittab file:
++
++                # Action on special keypress (Key Power)
++                kb::kbrequest:/sbin/shutdown -t1 -a -h -P now
++
++            And finally reload configuration by calling following commands:
++
++                # dpkg-reconfigure console-setup
++                # service console-setup reload
++                # init q
++
++        This overlay only handles shutdown. After shutdown, the system
++        can be powered up again by driving GPIO3 low. The default
++        configuration uses GPIO3 with a pullup, so if you connect a
++        button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
++        you get a shutdown and power-up button. Please note that
++        Raspberry Pi 1 Model B rev 1 uses GPIO1 instead of GPIO3.

++                                rising edge generates a key up event.
++                                When this is 0 (active high), this is
++                                reversed. The default is 1 (active low).
++
++        gpio_pull               Desired pull-up/down state (off, down, up)

++
++                                Note that the default pin (GPIO3) has an
++                                external pullup. Same applies for GPIO1

++        to disable transaction combining.
++        Do NOT use in conjunction with dtparam=i2c_vc=on. From the 5.4 kernel
++        onwards the base DT includes the use of i2c_mux_pinctrl to expose two
++        muxings of BSC0 - GPIOs 0&1, and whichever combination is used for the
++        camera and display connectors. This overlay disables that mux and
++        configures /dev/i2c0 to point at whichever set of pins is requested.
++        dtparam=i2c_vc=on will try and enable the mux, so combining the two
++        will cause conflicts.

++Load:   dtoverlay=w1-gpio-pullup,<param>=<val>
++Params: gpiopin                 GPIO for I/O (default "4")
++        extpullup               GPIO for external pullup (default "5")
++        pullup                  Now enabled by default (ignored)

++Name:   w5500
++Info:   Overlay for the Wiznet W5500 Ethernet Controller on SPI0
++Load:   dtoverlay=w5500,<param>=<val>
++Params: int_pin                 GPIO used for INT (default 25)
++

++Name:   watterott-display
++Info:   Watterott RPi-Display - 2.8" Touch Display
++        Linux has 2 drivers that support this display and this overlay supports
++        both.
++
++        Examples:
++          fbtft/fb_ili9341: dtoverlay=watterott-display
++          drm/mi0283qt: dtoverlay=watterott-display,drm,backlight-pwm,rotate=180
++
++        Some notable differences with the DRM driver compared to fbtft:
++        - The display is turned on when it's first used and not on driver load
++          as with fbtft. So if nothing uses the display it stays off.
++        - Can run with a higher SPI clock increasing framerate. This is possible
++          since the driver avoids messing up the controller configuration due to
++          transmission errors by running config commands at 10MHz and only pixel
++          data at full speed (occasional pixel glitch might occur).
++        - PWM backlight is supported.
++
++Load:   dtoverlay=watterott-display,<param>=<val>
++Params: speed                   Display SPI bus speed
++        rotate                  Display rotation {0,90,180,270}
++        fps                     Delay between frame updates (fbtft only)
++        debug                   Debug output level {0-7} (fbtft only)
++        xohms                   Touchpanel sensitivity (X-plate resistance)
++        swapxy                  Swap x and y axis
++        backlight               Change backlight GPIO pin {e.g. 12, 18}
++                                (fbtft only)
++        drm                     Use DRM/KMS driver mi0283qt instead of fbtft.
++                                Set the SPI clock to 70MHz.
++                                This has to be the first parameter.
++        backlight-pwm           Use pwm for backlight (drm only). NB: Disables
++                                audio headphone output as that also uses PWM.

++Troubleshooting
++===============
++
++If you are experiencing problems that you think are DT-related, enable DT
++diagnostic output by adding this to /boot/config.txt:
++
++    dtdebug=on
++
++and rebooting. Then run:
++
++    sudo vcdbg log msg
++
++and look for relevant messages.
++
++Further reading

++This is only meant to be a quick introduction to the subject of Device Tree on
++Raspberry Pi. There is a more complete explanation here:

++ * PiFace Digital, Device Tree Overlay.
++ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
++ *
++ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
++ * SPI GPIO port expander.
++ *
++ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
++ * and LEDs, plus two relays on the first two outputs. These output loads are
++ * active-high.
++ *
++ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
++ * with four on-board switches connecting them to ground. Inputs devices are
++ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
++ * activated for GPIO bank B.
++ *
++ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
++ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
++ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
++ * and JP2.
++ *
++ * You can tell the driver about these jumper configurations with the
++ * spi-present-mask bitmask:
++ *
++ *     | JP1 | JP2 | dtoverlay line in /boot/config.txt         |
++ *     | --- | --- | ------------------------------------------ |
++ *     |  0  |  0  | dtoverlay=pifacedigital                    |
++ *     |  0  |  0  | dtoverlay=pifacedigital:spi-present-mask=1 |
++ *     |  0  |  1  | dtoverlay=pifacedigital:spi-present-mask=2 |
++ *     |  1  |  0  | dtoverlay=pifacedigital:spi-present-mask=4 |
++ *     |  1  |  1  | dtoverlay=pifacedigital:spi-present-mask=8 |
++ *
++ * # Example
++ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
++ *
++ *     $ grep pifacedigital /boot/config.txt
++ *     dtoverlay=pifacedigital
++ *     $ sudo systemctl poweroff
++ *
++ * Attach the PiFace Digital and power on the Raspberry Pi.
++ * Then use the libgpiod tools to query the device:
++ *
++ *     $ sudo apt install gpiod
++ *     $ gpiodetect | grep mcp23s17
++ *     gpiochip2 [mcp23s17.0] (16 lines)
++ *
++ * Set GPIO outputs 0, 2 and 5:
++ *
++ *     $ gpioset gpiochip2 0=1 2=1 5=1
++ *
++ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
++ *
++ *     $ gpioget gpiochip2 {8..15}
++ *     1 1 1 1 1 1 1 1
++ *
++ * And even monitor interrupts:
++ *
++ *     $ gpiomon gpiochip2 {8..15}
++ *     event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
++ *     event:  RISING EDGE offset: 11 timestamp: [1597361663.062555051]

++//     sx150<x>-<n>-<m>          - Enables SX150X device on I2C#<n> with slave address <m>. <x> may be 1-9.
++//                                 <n> may be 0 or 1.  Permissible values of <m> (which is denoted in hex)
++//                                 depend on the device variant.
++//                                 For SX1501, SX1502, SX1504 and SX1505, <m> may be 20 or 21.
++//                                 For SX1503 and SX1506, <m> may be 20.
++//                                 For SX1507 and SX1509, <m> may be 3E, 3F, 70 or 71.
++//                                 For SX1508, <m> may be 20, 21, 22 or 23.
++//     sx150<x>-<n>-<m>-int-gpio - Integer, enables interrupts on SX150X device on I2C#<n> with slave address <m>,
++//                                 specifies the GPIO pin to which NINT output of SX150X is connected.
++//
++//
++// Example 1: A single SX1505 device on I2C#1 with its slave address set to 0x20 and NINT output connected to GPIO25:
++// dtoverlay=sx150x:sx1505-1-20,sx1505-1-20-int-gpio=25
++//
++// Example 2: Two SX1507 devices on I2C#0 with their slave addresses set to 0x3E and 0x70 (interrupts not used):
++// dtoverlay=sx150x:sx1507-0-3E,sx1507-0-70

+Initialise rpi-firmware before clk-bcm2835
+
+The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
+Platform Module) having been registered when it initialises; otherwise
+it assumes there is no TPM. It has been observed on BCM2835 that IMA
+is initialised before TPM, and that initialising the BCM2835 clock
+driver before the firmware driver has the effect of reversing this
+order.
+
+Change the firmware driver to initialise at core_initcall, delaying the
+BCM2835 clock driver to postcore_initcall.

+Subject: [PATCH 027/697] clk-bcm2835: Read max core clock from firmware
+
+The VPU is responsible for managing the core clock, usually under
+direction from the bcm2835-cpufreq driver but not via the clk-bcm2835
+driver. Since the core frequency can change without warning, it is
+safer to report the maximum clock rate to users of the core clock -
+I2C, SPI and the mini UART - to err on the safe side when calculating
+clock divisors.
+
+If the DT node for the clock driver includes a reference to the
+firmware node, use the firmware API to query the maximum core clock
+instead of reading the divider registers.
+
+Prior to this patch, a "100KHz" I2C bus was sometimes clocked at about
+160KHz. In particular, switching to the 4.9 kernel was likely to break
+SenseHAT usage on a Pi3.
+

+clk: bcm2835: Pass DT node to rpi_firmware_get
+
+The fw_node pointer has already been retrieved, and using it allows
+us to remove a downstream patch to the firmware driver.

+
+DSI0 can take the clock from either PLLA or PLLD. PLLA is
+the default muxing, but PLLD is considered the more stable.
+
+Switch to using PLLD.

+SQUASH: smsc95xx: Use dev_mod_addr to set MAC addr
+
+Since adeef3e32146 ("net: constify netdev->dev_addr") it has been
+illegal to write to the dev_addr MAC address field. Later commits
+have added explicit checks that it hasn't been modified by nefarious
+means. The dev_addr_mod helper function is the accepted way to change
+the dev_addr field, so use it.
+
+Squash with 96c1def63ee1 ("Allow mac address to be set in smsc95xx").

+ legacy API
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Load driver early since at least bcm2708_fb doesn't support deferred
+probing and even if it did, we don't want the video driver deferred.
+Support the legacy DMA API which is needed by bcm2708_fb.
+Don't mask out channel 2.

+
+bcm2835-dma: Add support for per-channel flags
+
+Add the ability to interpret the high bits of the dreq specifier as
+flags to be included in the DMA_CS register. The motivation for this
+change is the ability to set the DISDEBUG flag for SD card transfers
+to avoid corruption when using the VPU debugger.

+
+bcm2835-dma: Add proper 40-bit DMA support
+
+BCM2711 has 4 DMA channels with a 40-bit address range, allowing them
+to access the full 4GB of memory on a Pi 4.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.org>
+
+bcm2835-dma: Derive slave DMA addresses correctly
+
+Slave addresses for DMA are meant to be supplied as physical addresses
+(contrary to what struct snd_dmaengine_dai_dma_data does). It is up to
+the DMA controller driver to perform the translation based on its own
+view of the world, as described in Device Tree.
+
+Now that the Pi Device Trees have the correct peripheral mappings,
+replace the hacky address munging with phys_to_dma().
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+bcm2835-dma: Add NO_WAIT_RESP flag
+
+Use bit 27 of the dreq value (the second cell of the DT DMA descriptor)
+to request that the WAIT_RESP bit is not set.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+bcm2835-dma: Advertise the full DMA range
+
+Unless the DMA mask is set wider than 32 bits, DMA mapping will use a
+bounce buffer.

+
+bcm2835-dma: only reserve channel 0 if legacy dma driver is enabled
+
+If CONFIG_DMA_BCM2708 isn't enabled there's no need to mask out
+one of the already scarce DMA channels.

+
+dmaengine: bcm2835: Fix position reporting for 40 bits channels
+
+For 40 bits channels, the position is reported by reading the upper byte
+in the SRCI/DESTI registers. However the driver adds that upper byte
+with an 8-bits left shift, while it should be 32.

+dmaengine: bcm2835: Fix descriptors usage for 40-bits channels
+
+The bcm2835_dma_create_cb_chain() function is in charge of building up
+the descriptors chain for a given transfer.
+
+It was initially supporting only the BCM2835-style DMA controller, and
+was later expanded to support controllers with 40-bits channels that use
+a different descriptor layout.
+
+However, some part of the function only use the old style descriptor,
+even when building a chain of new-style descriptors, resulting in weird
+bugs.

+
+bcm2835-dma: Fix dma_abort for non-40bit channels
+
+The sequence we were doing was not safe.
+
+Clearing CS meant BCM2835_DMA_WAIT_FOR_WRITES was cleared
+and so polling BCM2835_DMA_WAITING_FOR_WRITES has no benefit
+
+Broadcom have provided a recommended sequence to abort
+a dma lite channel, so switch to that.

+Subject: [PATCH 044/697] watchdog: bcm2835: Support setting reboot partition
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Raspberry Pi firmware looks at the RSTS register to know which
+partition to boot from. The reboot syscall command
+LINUX_REBOOT_CMD_RESTART2 supports passing in a string argument.
+
+Add support for passing in a partition number 0..63 to boot from.
+Partition 63 is a special partiton indicating halt.
+If the partition doesn't exist, the firmware falls back to partition 0.

+reboot: Use power off rather than busy spinning when halt is requested
+
+Busy spinning after halt is dumb
+We've previously applied this patch to arch/arm
+but it is currenltly missing in arch/arm64
+
+Pi4 after "sudo halt" uses 520mA
+Pi4 after "sudo shutdown now" uses 310mA
+
+Make them both use the lower powered option

+Subject: [PATCH 047/697] Update vfpmodule.c
+
+Christopher Alexander Tobias Schulze - May 2, 2015, 11:57 a.m.
+This patch fixes a problem with VFP state save and restore related
+to exception handling (panic with message "BUG: unsupported FP
+instruction in kernel mode") present on VFP11 floating point units
+(as used with ARM1176JZF-S CPUs, e.g. on first generation Raspberry
+Pi boards). This patch was developed and discussed on
+
+   https://github.com/raspberrypi/linux/issues/859
+
+A precondition to see the crashes is that floating point exception
+traps are enabled. In this case, the VFP11 might determine that a FPU
+operation needs to trap at a point in time when it is not possible to
+signal this to the ARM11 core any more. The VFP11 will then set the
+FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases,
+a second opcode might have been accepted by the VFP11 before the
+exception was detected and could be reported to the ARM11 - in this
+case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in
+FPINST2.)
+
+If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued
+by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode
+trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits
+to decide what actions to take, i.e., whether to emulate the opcodes
+found in FPINST and FPINST2, and whether to retry the bounced instruction.
+
+If a user space application has left the VFP11 in this "pending trap"
+state, the next FPU opcode issued to the VFP11 might actually be the
+VSTMIA operation vfp_save_state() uses to store the FPU registers
+to memory (in our test cases, when building the signal stack frame).
+In this case, the kernel crashes as described above.
+
+This patch fixes the problem by making sure that vfp_save_state() is
+always entered with FPEXC.EX cleared. (The current value of FPEXC has
+already been saved, so this does not corrupt the context. Clearing
+FPEXC.EX has no effects on FPINST or FPINST2. Also note that many
+callers already modify FPEXC by setting FPEXC.EN before invoking
+vfp_save_state().)
+
+This patch also addresses a second problem related to FPEXC.EX: After
+returning from signal handling, the kernel reloads the VFP context
+from the user mode stack. However, the current code explicitly clears
+both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these
+bits to be preserved, this patch disables clearing them for VFP
+implementations belonging to architecture 1. There should be no
+negative side effects: the user can set both bits by executing FPU
+opcodes anyway, and while user code may now place arbitrary values
+into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support
+code knows which instructions can be emulated, and rejects other
+opcodes with "unhandled bounce" messages, so there should be no
+security impact from allowing reloading FPEXC.EX and FPEXC.FP2V.

+Subject: [PATCH 048/697] i2c: bcm2835: Add debug support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds a debug module parameter to aid in debugging transfer issues
+by printing info to the kernel log. When enabled, status values are
+collected in the interrupt routine and msg info in
+bcm2835_i2c_start_transfer(). This is done in a way that tries to avoid
+affecting timing. Having printk in the isr can mask issues.
+
+debug values (additive):
+1: Print info on error
+2: Print info on all transfers
+3: Print messages before transfer is started
+
+The value can be changed at runtime:
+/sys/module/i2c_bcm2835/parameters/debug
+
+Example output, debug=3:
+[  747.114448] bcm2835_i2c_xfer: msg(1/2) write addr=0x54, len=2 flags= [i2c1]
+[  747.114463] bcm2835_i2c_xfer: msg(2/2) read addr=0x54, len=32 flags= [i2c1]

+Subject: [PATCH 049/697] irqchip: irq-bcm2836: Remove regmap and syscon use
+
+The syscon node defines a register range that duplicates that used by
+the local_intc node on bcm2836/7. Since irq-bcm2835 and irq-bcm2836 are
+built in and always present together (both drivers are enabled by
+CONFIG_ARCH_BCM2835), it is possible to replace the syscon usage with a
+global variable that simplifies the code. Doing so does lose the
+locking provided by regmap, but as only one side is using the regmap
+interface (irq-bcm2835 uses readl and write) there is no loss of
+atomicity.

+
+The BCM2835 PL011 implementation seems to have a bug that can lead to a
+transmission lockup if CTS changes frequently. A workaround was added to
+the driver with a vendor-specific flag to enable it, but this flag is
+currently not set for ARM implementations.
+
+Add a "cts-event-workaround" property to Pi DTBs and use the presence
+of that property to force the flag to be enabled in the driver.

+Subject: [PATCH 052/697] tty: amba-pl011: Avoid rare write-when-full error
+
+Under some circumstances on BCM283x processors data loss can be
+observed - a single byte missing from the TX output stream. These bytes
+are always the last byte of a batch of 8 written from pl011_tx_chars
+when from_irq is true, meaning that the FIFO full flag is not checked
+before writing.
+
+The transmit optimisation relies on the FIFO being half-empty when the
+TX interrupt is raised. Instrumenting the driver further showed that
+the failure case correlated with the TX FIFO full flag being set at the
+point where the last byte was written to the data register, which
+explains the data loss but not how the FIFO appeared to be prematurely
+full. A possible explanation is that a FIFO write was in flight at the
+time the interrupt was raised, but as yet there is no hypothesis as to
+how this might occur.
+
+In the absence of a clear understanding of the failure mechanism, avoid
+the problem by checking the FIFO levels before writing the last byte of
+the group, which will have minimal performance impact.

+Add FIQ patch to dwc_otg driver. Enable with dwc_otg.fiq_fix_enable=1. Should give about 10% more ARM performance.
+Thanks to Gordon and Costas
+
+Avoid dynamic memory allocation for channel lock in USB driver. Thanks ddv2005.
+
+Add NAK holdoff scheme. Enabled by default, disable with dwc_otg.nak_holdoff_enable=0. Thanks gsh
+
+Make sure we wait for the reset to finish
+
+dwc_otg: fix bug in dwc_otg_hcd.c resulting in silent kernel
+	 memory corruption, escalating to OOPS under high USB load.
+
+dwc_otg: Fix unsafe access of QTD during URB enqueue
+
+In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
+transaction could complete almost immediately after the qtd was assigned
+to a host channel during URB enqueue, which meant the qtd pointer was no
+longer valid having been completed and removed. Usually, this resulted in
+an OOPS during URB submission. By predetermining whether transactions
+need to be queued or not, this unsafe pointer access is avoided.
+
+This bug was only evident on the Pi model A where a device was attached
+that had no periodic endpoints (e.g. USB pendrive or some wlan devices).
+
+dwc_otg: Fix incorrect URB allocation error handling
+
+If the memory allocation for a dwc_otg_urb failed, the kernel would OOPS
+because for some reason a member of the *unallocated* struct was set to
+zero. Error handling changed to fail correctly.
+
+dwc_otg: fix potential use-after-free case in interrupt handler
+
+If a transaction had previously aborted, certain interrupts are
+enabled to track error counts and reset where necessary. On IN
+endpoints the host generates an ACK interrupt near-simultaneously
+with completion of transfer. In the case where this transfer had
+previously had an error, this results in a use-after-free on
+the QTD memory space with a 1-byte length being overwritten to

+dwc_otg: add handling of SPLIT transaction data toggle errors
+
+Previously a data toggle error on packets from a USB1.1 device behind
+a TT would result in the Pi locking up as the driver never handled
+the associated interrupt. Patch adds basic retry mechanism and
+interrupt acknowledgement to cater for either a chance toggle error or
+for devices that have a broken initial toggle state (FT8U232/FT232BM).
+
+dwc_otg: implement tasklet for returning URBs to usbcore hcd layer
+
+The dwc_otg driver interrupt handler for transfer completion will spend
+a very long time with interrupts disabled when a URB is completed -
+this is because usb_hcd_giveback_urb is called from within the handler
+which for a USB device driver with complicated processing (e.g. webcam)
+will take an exorbitant amount of time to complete. This results in
+missed completion interrupts for other USB packets which lead to them
+being dropped due to microframe overruns.
+
+This patch splits returning the URB to the usb hcd layer into a
+high-priority tasklet. This will have most benefit for isochronous IN
+transfers but will also have incidental benefit where multiple periodic
+devices are active at once.
+
+dwc_otg: fix NAK holdoff and allow on split transactions only
+
+This corrects a bug where if a single active non-periodic endpoint
+had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
+would get skipped and never get queued again. This would result in
+a silent device until error detection (automatic or otherwise) would
+either reset the device or flush and requeue the URBs.
+
+Additionally the NAK holdoff was enabled for all transactions - this
+would potentially stall a HS endpoint for 1ms if a previous error state
+enabled this interrupt and the next response was a NAK. Fix so that
+only split transactions get held off.
+
+dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock held in completion handler
+
+usb_hcd_unlink_urb_from_ep must be called with the HCD lock held.  Calling it
+asynchronously in the tasklet was not safe (regression in
+c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
+
+This change unlinks it from the endpoint prior to queueing it for handling in
+the tasklet, and also adds a check to ensure the urb is OK to be unlinked
+before doing so.
+
+NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
+when a USB device was unplugged/replugged during data transfer.  This effect
+was reproduced using automated USB port power control, hundreds of replug
+events were performed during active transfers to confirm that the problem was
+eliminated.
+
+USB fix using a FIQ to implement split transactions
+
+This commit adds a FIQ implementaion that schedules
+the split transactions using a FIQ so we don't get
+held off by the interrupt latency of Linux
+

+
+dcw_otg: avoid logging function that can cause panics

+See: https://github.com/raspberrypi/firmware/issues/21
+Thanks to cleverca22 for fix
+
+dwc_otg: mask correct interrupts after transaction error recovery
+
+The dwc_otg driver will unmask certain interrupts on a transaction
+that previously halted in the error state in order to reset the
+QTD error count. The various fine-grained interrupt handlers do not
+consider that other interrupts besides themselves were unmasked.
+
+By disabling the two other interrupts only ever enabled in DMA mode
+for this purpose, we can avoid unnecessary function calls in the
+IRQ handler. This will also prevent an unneccesary FIQ interrupt
+from being generated if the FIQ is enabled.
+
+dwc_otg: fiq: prevent FIQ thrash and incorrect state passing to IRQ
+
+In the case of a transaction to a device that had previously aborted
+due to an error, several interrupts are enabled to reset the error
+count when a device responds. This has the side-effect of making the
+FIQ thrash because the hardware will generate multiple instances of
+a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
+on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
+associated interrupts.
+
+Additionally, on non-split transactions make sure that only unmasked
+interrupts are cleared. This caused a hard-to-trigger but serious
+race condition when you had the combination of an endpoint awaiting
+error recovery and a transaction completed on an endpoint - due to
+the sequencing and timing of interrupts generated by the dwc_otg core,
+it was possible to confuse the IRQ handler.
+
+Fix function tracing
+
+dwc_otg: whitespace cleanup in dwc_otg_urb_enqueue
+
+dwc_otg: prevent OOPSes during device disconnects
+
+The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
+access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
+friends does not occur within a critical section and so if a device
+was unplugged during activity there was a high chance that the
+usbcore hub_thread would try to disable the endpoint with partially-
+formed entries in the URB queue. This would result in BUG() or null
+pointer dereferences.
+
+Fix so that access of urb->hcpriv, enqueuing to the hardware and
+adding to usbcore endpoint URB lists is contained within a single
+critical section.
+
+dwc_otg: prevent BUG() in TT allocation if hub address is > 16
+
+A fixed-size array is used to track TT allocation. This was
+previously set to 16 which caused a crash because
+dwc_otg_hcd_allocate_port would read past the end of the array.
+
+This was hit if a hub was plugged in which enumerated as addr > 16,
+due to previous device resets or unplugs.
+
+Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
+to a large size if 128 hub addresses are supported. This field is
+for debug only for tracking which frame an allocate happened in.
+
+dwc_otg: make channel halts with unknown state less damaging
+
+If the IRQ received a channel halt interrupt through the FIQ
+with no other bits set, the IRQ would not release the host
+channel and never complete the URB.
+
+Add catchall handling to treat as a transaction error and retry.
+
+dwc_otg: fiq_split: use TTs with more granularity
+
+This fixes certain issues with split transaction scheduling.
+
+- Isochronous multi-packet OUT transactions now hog the TT until
+  they are completed - this prevents hubs aborting transactions
+  if they get a periodic start-split out-of-order
+- Don't perform TT allocation on non-periodic endpoints - this
+  allows simultaneous use of the TT's bulk/control and periodic
+  transaction buffers
+
+This commit will mainly affect USB audio playback.
+
+dwc_otg: fix potential sleep while atomic during urb enqueue
+
+Fixes a regression introduced with eb1b482a. Kmalloc called from
+dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
+the GPF_ATOMIC flag set. Force this flag when inside the larger
+critical section.
+
+dwc_otg: make fiq_split_enable imply fiq_fix_enable
+
+Failing to set up the FIQ correctly would result in
+"IRQ 32: nobody cared" errors in dmesg.
+
+dwc_otg: prevent crashes on host port disconnects
+
+Fix several issues resulting in crashes or inconsistent state
+if a Model A root port was disconnected.
+
+- Clean up queue heads properly in kill_urbs_in_qh_list by
+  removing the empty QHs from the schedule lists
+- Set the halt status properly to prevent IRQ handlers from
+  using freed memory
+- Add fiq_split related cleanup for saved registers
+- Make microframe scheduling reclaim host channels if
+  active during a disconnect
+- Abort URBs with -ESHUTDOWN status response, informing
+  device drivers so they respond in a more correct fashion
+  and don't try to resubmit URBs
+- Prevent IRQ handlers from attempting to handle channel
+  interrupts if the associated URB was dequeued (and the
+  driver state was cleared)
+
+dwc_otg: prevent leaking URBs during enqueue
+
+A dwc_otg_urb would get leaked if the HCD enqueue function
+failed for any reason. Free the URB at the appropriate points.
+
+dwc_otg: Enable NAK holdoff for control split transactions
+
+Certain low-speed devices take a very long time to complete a
+data or status stage of a control transaction, producing NAK
+responses until they complete internal processing - the USB2.0
+spec limit is up to 500mS. This causes the same type of interrupt
+storm as seen with USB-serial dongles prior to c8edb238.
+
+In certain circumstances, usually while booting, this interrupt
+storm could cause SD card timeouts.
+
+dwc_otg: Fix for occasional lockup on boot when doing a USB reset
+
+dwc_otg: Don't issue traffic to LS devices in FS mode
+
+Issuing low-speed packets when the root port is in full-speed mode
+causes the root port to stop responding. Explicitly fail when
+enqueuing URBs to a LS endpoint on a FS bus.
+
+Fix ARM architecture issue with local_irq_restore()
+
+If local_fiq_enable() is called before a local_irq_restore(flags) where
+the flags variable has the F bit set, the FIQ will be erroneously disabled.
+
+Fixup arch_local_irq_restore to avoid trampling the F bit in CPSR.
+
+Also fix some of the hacks previously implemented for previous dwc_otg
+incarnations.
+
+dwc_otg: fiq_fsm: Base commit for driver rewrite
+
+This commit removes the previous FIQ fixes entirely and adds fiq_fsm.
+
+This rewrite features much more complete support for split transactions
+and takes into account several OTG hardware bugs. High-speed
+isochronous transactions are also capable of being performed by fiq_fsm.
+
+All driver options have been removed and replaced with:
+  - dwc_otg.fiq_enable (bool)
+  - dwc_otg.fiq_fsm_enable (bool)
+  - dwc_otg.fiq_fsm_mask (bitmask)
+  - dwc_otg.nak_holdoff (unsigned int)
+
+Defaults are specified such that fiq_fsm behaves similarly to the
+previously implemented FIQ fixes.
+
+fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
+
+If the transfer associated with a QTD failed due to a bus error, the HCD
+would retry the transfer up to 3 times (implementing the USB2.0
+three-strikes retry in software).
+
+Due to the masking mechanism used by fiq_fsm, it is only possible to pass
+a single interrupt through to the HCD per-transfer.
+
+In this instance host channels would fall off the radar because the error
+reset would function, but the subsequent channel halt would be lost.
+
+Push the error count reset into the FIQ handler.
+
+fiq_fsm: Implement timeout mechanism
+
+For full-speed endpoints with a large packet size, interrupt latency
+runs the risk of the FIQ starting a transaction too late in a full-speed
+frame. If the device is still transmitting data when EOF2 for the
+downstream frame occurs, the hub will disable the port. This change is
+not reflected in the hub status endpoint and the device becomes
+unresponsive.
+
+Prevent high-bandwidth transactions from being started too late in a
+frame. The mechanism is not guaranteed: a combination of bit stuffing
+and hub latency may still result in a device overrunning.
+
+fiq_fsm: fix bounce buffer utilisation for Isochronous OUT
+
+Multi-packet isochronous OUT transactions were subject to a few bounday
+bugs. Fix them.
+
+Audio playback is now much more robust: however, an issue stands with
+devices that have adaptive sinks - ALSA plays samples too fast.
+
+dwc_otg: Return full-speed frame numbers in HS mode
+
+The frame counter increments on every *microframe* in high-speed mode.
+Most device drivers expect this number to be in full-speed frames - this
+caused considerable confusion to e.g. snd_usb_audio which uses the
+frame counter to estimate the number of samples played.
+
+fiq_fsm: save PID on completion of interrupt OUT transfers
+
+Also add edge case handling for interrupt transports.
+
+Note that for periodic split IN, data toggles are unimplemented in the
+OTG host hardware - it unconditionally accepts any PID.
+
+fiq_fsm: add missing case for fiq_fsm_tt_in_use()
+
+Certain combinations of bitrate and endpoint activity could
+result in a periodic transaction erroneously getting started
+while the previous Isochronous OUT was still active.
+
+fiq_fsm: clear hcintmsk for aborted transactions
+
+Prevents the FIQ from erroneously handling interrupts
+on a timed out channel.
+
+fiq_fsm: enable by default
+
+fiq_fsm: fix dequeues for non-periodic split transactions
+
+If a dequeue happened between the SSPLIT and CSPLIT phases of the
+transaction, the HCD would never receive an interrupt.
+
+fiq_fsm: Disable by default
+
+fiq_fsm: Handle HC babble errors
+
+The HCTSIZ transfer size field raises a babble interrupt if
+the counter wraps. Handle the resulting interrupt in this case.
+
+dwc_otg: fix interrupt registration for fiq_enable=0
+
+Additionally make the module parameter conditional for wherever
+hcd->fiq_state is touched.
+
+fiq_fsm: Enable by default
+
+dwc_otg: Fix various issues with root port and transaction errors
+
+Process the host port interrupts correctly (and don't trample them).
+Root port hotplug now functional again.
+
+Fix a few thinkos with the transaction error passthrough for fiq_fsm.
+
+fiq_fsm: Implement hack for Split Interrupt transactions
+
+Hubs aren't too picky about which endpoint we send Control type split
+transactions to. By treating Interrupt transfers as Control, it is
+possible to use the non-periodic queue in the OTG core as well as the
+non-periodic FIFOs in the hub itself. This massively reduces the
+microframe exclusivity/contention that periodic split transactions
+otherwise have to enforce.
+
+It goes without saying that this is a fairly egregious USB specification
+violation, but it works.
+
+Original idea by Hans Petter Selasky @ FreeBSD.org.
+
+dwc_otg: FIQ support on SMP. Set up FIQ stack and handler on Core 0 only.
+
+dwc_otg: introduce fiq_fsm_spin(un|)lock()
+
+SMP safety for the FIQ relies on register read-modify write cycles being
+completed in the correct order. Several places in the DWC code modify
+registers also touched by the FIQ. Protect these by a bare-bones lock
+mechanism.
+
+This also makes it possible to run the FIQ and IRQ handlers on different
+cores.
+
+fiq_fsm: fix build on bcm2708 and bcm2709 platforms
+

+
+dwc_otg: fixup read-modify-write in critical paths
+
+Be more careful about read-modify-write on registers that the FIQ
+also touches.
+
+Guard fiq_fsm_spin_lock with fiq_enable check
+
+fiq_fsm: Falling out of the state machine isn't fatal
+
+This edge case can be hit if the port is disabled while the FIQ is
+in the middle of a transaction. Make the effects less severe.
+
+Also get rid of the useless return value.

+
+dwc_otg: make nak_holdoff work as intended with empty queues
+
+If URBs reading from non-periodic split endpoints were dequeued and

+Fixup qh->nak_frame in dwc_otg_hcd_urb_dequeue and also guard against
+a case where a single URB is submitted to the endpoint, a NAK was
+received on the transfer immediately prior to receiving data and the
+device subsequently resubmits another URB past the qh->nak_frame interval.

+
+dwc_otg: fix split transaction data toggle handling around dequeues
+

+- Reset hc->start_pkt_count properly in assign_and_init_hc()
+
+dwc_otg: fix several potential crash sources
+
+On root port disconnect events, the host driver state is cleared and
+in-progress host channels are forcibly stopped. This doesn't play
+well with the FIQ running in the background, so:
+- Guard the disconnect callback with both the host spinlock and FIQ
+  spinlock
+- Move qtd dereference in dwc_otg_handle_hc_fsm() after the early-out

+- Turn catch-all BUG()s in dwc_otg_handle_hc_fsm() into warnings.

+dwc_otg: fix bug with port_addr assignment for single-TT hubs
+
+See https://github.com/raspberrypi/linux/issues/2734
+
+The "Hub Port" field in the split transaction packet was always set
+to 1 for single-TT hubs. The majority of single-TT hub products
+apparently ignore this field and broadcast to all downstream enabled
+ports, which masked the issue. A subset of hub devices apparently
+need the port number to be exact or split transactions will fail.

+usb: dwc_otg: Use dma allocation for mphi dummy_send buffer
+
+The FIQ driver used a kzalloc'ed buffer for dummy_send,
+passing a kernel virtual address to the hardware block.
+The buffer is only ever used for a dummy read, so it
+should be harmless, but there is the chance that it will
+cause exceptions.
+
+Use a dma allocation so that we have a genuine bus address,
+and read from that.
+Free the allocation when done for good measure.

+dwc_otg: only do_split when we actually need to do a split
+
+The previous test would fail if the root port was in fullspeed mode
+and there was a hub between the FS device and the root port. While
+the transfer worked, the schedule mangling performed for high-speed
+split transfers would break leading to an 8ms polling interval.
+
+dwc_otg: fix locking around dequeueing and killing URBs
+
+kill_urbs_in_qh_list() is practically only ever called with the fiq lock
+already held, so don't spinlock twice in the case where we need to cancel
+an isochronous transfer.
+
+Also fix up a case where the global interrupt register could be read with
+the fiq lock not held.

+
+ARM64/DWC_OTG: Port dwc_otg driver to ARM64
+
+In ARM64, the FIQ mechanism used by this driver is not current
+implemented.   As a workaround, reqular IRQ is used instead
+of FIQ.
+
+In a separate change, the IRQ-CPU mapping is round robined
+on ARM64 to increase concurrency and allow multiple interrupts
+to be serviced at a time.  This reduces the need for FIQ.
+
+Tests Run:
+
+This mechanism is most likely to break when multiple USB devices
+are attached at the same time.  So the system was tested under
+stress.
+
+Devices:
+
+1. USB Speakers playing back a FLAC audio through VLC
+   at 96KHz.(Higher then typically, but supported on my speakers).
+
+2. sftp transferring large files through the buildin ethernet
+   connection which is connected through USB.
+
+3. Keyboard and mouse attached and being used.
+
+Although I do occasionally hear some glitches, the music seems to
+play quite well.

+dwc_otg: use align_buf for small IN control transfers (#3150)
+
+The hardware will do a 4-byte write to memory on any IN packet received
+that is between 1 and 3 bytes long. This tramples memory in the uvcvideo
+driver, as it uses a sequence of 1- and 2-byte control transfers to
+query the min/max/range/step of each individual camera control and
+gives us buffers that are offsets into a struct.
+
+Catch small control transfers in the data phase and use the align_buf
+to bounce the correct number of bytes into the URB's buffer.
+
+In general, short packets on non-control endpoints should be OK as URBs
+should have enough buffer space for a wMaxPacket size transfer.

+dwc_otg: checking the urb->transfer_buffer too early (#3332)
+
+After enable the HIGHMEM and VMSPLIT_3G, the dwc_otg driver doesn't
+work well on Pi2/3 boards with 1G physical ram. Users experience
+the failure when copying a file of 600M size to the USB stick. And
+at the same time, the dmesg shows:

+
+When this happens, the sg_buf sent to the driver is located in the

+transfer_buffer to NULL if the sg_buf is in highmem, but in the
+dwc_otg driver, it returns -EINVAL unconditionally if transfer_buffer
+is NULL.
+
+The driver can handle the situation of buffer to be NULL, if it is in
+DMA mode, it will convert an address from transfer_dma.
+
+But if the conversion fails or it is in the PIO mode, we should check
+buffer and return -EINVAL if it is NULL.

+dwc_otg: constrain endpoint max packet and transfer size on split IN
+
+The hcd would unconditionally set the transfer length to the endpoint
+packet size for non-isoc IN transfers. If the remaining buffer length
+was less than the length of returned data, random memory would get
+scribbled over, with bad effects if it crossed a page boundary.
+
+Force a babble error if this happens by limiting the max transfer size
+to the available buffer space. DMA will stop writing to memory on a

+The hardware expects xfersize to be an integer multiple of maxpacket

+dwc_otg: fiq_fsm: add a barrier on entry into FIQ handler(s)
+
+On BCM2835, there is no hardware guarantee that multiple outstanding
+reads to different peripherals will complete in-order. The FIQ code
+uses peripheral reads without barriers for performance, so in the case
+where a read to a slow peripheral was issued immediately prior to FIQ
+entry, the first peripheral read that the FIQ did could end up with
+wrong read data returned.
+
+Add dsb(sy) on entry so that all outstanding reads are retired.
+
+The FIQ only issues reads to the dwc_otg core, so per-read barriers
+in the handler itself are not required.
+
+On BCM2836 and BCM2837 the barrier is not strictly required due to
+differences in how the peripheral bus is implemented, but having
+arch-specific handlers that introduce different latencies is risky.

++/*
++ * The File-backed Storage Gadget acts as a USB Mass Storage device,
++ * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
++ * to providing an example of a genuinely useful gadget driver for a USB
++ * device, it also illustrates a technique of double-buffering for increased
++ * throughput.  Last but not least, it gives an easy way to probe the
++ * behavior of the Mass Storage drivers in a USB host.
++ *
++ * Backing storage is provided by a regular file or a block device, specified
++ * by the "file" module parameter.  Access can be limited to read-only by
++ * setting the optional "ro" module parameter.  (For CD-ROM emulation,
++ * access is always read-only.)  The gadget will indicate that it has
++ * removable media if the optional "removable" module parameter is set.
++ *
++ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
++ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
++ * by the optional "transport" module parameter.  It also supports the
++ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
++ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
++ * the optional "protocol" module parameter.  In addition, the default
++ * Vendor ID, Product ID, release number and serial number can be overridden.
++ *
++ * There is support for multiple logical units (LUNs), each of which has
++ * its own backing file.  The number of LUNs can be set using the optional
++ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
++ * files are specified using comma-separated lists for "file" and "ro".
++ * The default number of LUNs is taken from the number of "file" elements;
++ * it is 1 if "file" is not given.  If "removable" is not set then a backing
++ * file must be specified for each LUN.  If it is set, then an unspecified
++ * or empty backing filename means the LUN's medium is not loaded.  Ideally
++ * each LUN would be settable independently as a disk drive or a CD-ROM
++ * drive, but currently all LUNs have to be the same type.  The CD-ROM
++ * emulation includes a single data track and no audio tracks; hence there
++ * need be only one backing file per LUN.
++ *
++ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
++ * needed (an interrupt-out endpoint is also needed for CBI).  The memory
++ * requirement amounts to two 16K buffers, size configurable by a parameter.
++ * Support is included for both full-speed and high-speed operation.
++ *
++ * Note that the driver is slightly non-portable in that it assumes a
++ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
++ * interrupt-in endpoints.  With most device controllers this isn't an
++ * issue, but there may be some with hardware restrictions that prevent
++ * a buffer from being used by more than one endpoint.
++ *
++ * Module options:
++ *
++ *	file=filename[,filename...]
++ *				Required if "removable" is not set, names of
++ *					the files or block devices used for
++ *					backing storage
++ *	serial=HHHH...		Required serial number (string of hex chars)
++ *	ro=b[,b...]		Default false, booleans for read-only access
++ *	removable		Default false, boolean for removable media
++ *	luns=N			Default N = number of filenames, number of
++ *					LUNs to support
++ *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
++ *					in SCSI WRITE(10,12) commands
++ *	stall			Default determined according to the type of
++ *					USB device controller (usually true),
++ *					boolean to permit the driver to halt
++ *					bulk endpoints
++ *	cdrom			Default false, boolean for whether to emulate
++ *					a CD-ROM drive
++ *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
++ *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
++ *					ATAPI, QIC, UFI, 8070, or SCSI;
++ *					also 1 - 6)
++ *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
++ *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
++ *	release=0xRRRR		Override the USB release number (bcdDevice)
++ *	buflen=N		Default N=16384, buffer size used (will be
++ *					rounded down to a multiple of
++ *					PAGE_CACHE_SIZE)
++ *
++ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
++ * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
++ * default values are used for everything else.
++ *
++ * The pathnames of the backing files and the ro settings are available in
++ * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
++ * the gadget's sysfs directory.  If the "removable" option is set, writing to
++ * these files will simulate ejecting/loading the medium (writing an empty
++ * line means eject) and adjusting a write-enable tab.  Changes to the ro
++ * setting are not allowed when the medium is loaded or if CD-ROM emulation
++ * is being used.
++ *
++ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
++ * The driver's SCSI command interface was based on the "Information
++ * technology - Small Computer System Interface - 2" document from
++ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
++ * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
++ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
++ * "Universal Serial Bus Mass Storage Class UFI Command Specification"
++ * document, Revision 1.0, December 14, 1998, available at
++ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.
++ */
++
++
++/*
++ *				Driver Design
++ *
++ * The FSG driver is fairly straightforward.  There is a main kernel
++ * thread that handles most of the work.  Interrupt routines field
++ * callbacks from the controller driver: bulk- and interrupt-request
++ * completion notifications, endpoint-0 events, and disconnect events.
++ * Completion events are passed to the main thread by wakeup calls.  Many
++ * ep0 requests are handled at interrupt time, but SetInterface,
++ * SetConfiguration, and device reset requests are forwarded to the
++ * thread in the form of "exceptions" using SIGUSR1 signals (since they
++ * should interrupt any ongoing file I/O operations).
++ *
++ * The thread's main routine implements the standard command/data/status
++ * parts of a SCSI interaction.  It and its subroutines are full of tests
++ * for pending signals/exceptions -- all this polling is necessary since
++ * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
++ * indication that the driver really wants to be running in userspace.)
++ * An important point is that so long as the thread is alive it keeps an
++ * open reference to the backing file.  This will prevent unmounting
++ * the backing file's underlying filesystem and could cause problems
++ * during system shutdown, for example.  To prevent such problems, the
++ * thread catches INT, TERM, and KILL signals and converts them into
++ * an EXIT exception.
++ *
++ * In normal operation the main thread is started during the gadget's
++ * fsg_bind() callback and stopped during fsg_unbind().  But it can also
++ * exit when it receives a signal, and there's no point leaving the
++ * gadget running when the thread is dead.  So just before the thread
++ * exits, it deregisters the gadget driver.  This makes things a little
++ * tricky: The driver is deregistered at two places, and the exiting
++ * thread can indirectly call fsg_unbind() which in turn can tell the
++ * thread to exit.  The first problem is resolved through the use of the
++ * REGISTERED atomic bitflag; the driver will only be deregistered once.
++ * The second problem is resolved by having fsg_unbind() check
++ * fsg->state; it won't try to stop the thread if the state is already
++ * FSG_STATE_TERMINATED.
++ *
++ * To provide maximum throughput, the driver uses a circular pipeline of
++ * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
++ * arbitrarily long; in practice the benefits don't justify having more
++ * than 2 stages (i.e., double buffering).  But it helps to think of the
++ * pipeline as being a long one.  Each buffer head contains a bulk-in and
++ * a bulk-out request pointer (since the buffer can be used for both
++ * output and input -- directions always are given from the host's
++ * point of view) as well as a pointer to the buffer and various state
++ * variables.
++ *
++ * Use of the pipeline follows a simple protocol.  There is a variable
++ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
++ * At any time that buffer head may still be in use from an earlier
++ * request, so each buffer head has a state variable indicating whether
++ * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
++ * buffer head to be EMPTY, filling the buffer either by file I/O or by
++ * USB I/O (during which the buffer head is BUSY), and marking the buffer
++ * head FULL when the I/O is complete.  Then the buffer will be emptied
++ * (again possibly by USB I/O, during which it is marked BUSY) and
++ * finally marked EMPTY again (possibly by a completion routine).
++ *
++ * A module parameter tells the driver to avoid stalling the bulk
++ * endpoints wherever the transport specification allows.  This is
++ * necessary for some UDCs like the SuperH, which cannot reliably clear a
++ * halt on a bulk endpoint.  However, under certain circumstances the
++ * Bulk-only specification requires a stall.  In such cases the driver
++ * will halt the endpoint and set a flag indicating that it should clear
++ * the halt in software during the next device reset.  Hopefully this
++ * will permit everything to work correctly.  Furthermore, although the
++ * specification allows the bulk-out endpoint to halt when the host sends
++ * too much data, implementing this would cause an unavoidable race.
++ * The driver will always use the "no-stall" approach for OUT transfers.
++ *
++ * One subtle point concerns sending status-stage responses for ep0
++ * requests.  Some of these requests, such as device reset, can involve
++ * interrupting an ongoing file I/O operation, which might take an
++ * arbitrarily long time.  During that delay the host might give up on
++ * the original ep0 request and issue a new one.  When that happens the
++ * driver should not notify the host about completion of the original
++ * request, as the host will no longer be waiting for it.  So the driver
++ * assigns to each ep0 request a unique tag, and it keeps track of the
++ * tag value of the request associated with a long-running exception
++ * (device-reset, interface-change, or configuration-change).  When the
++ * exception handler is finished, the status-stage response is submitted
++ * only if the current ep0 request tag is equal to the exception request
++ * tag.  Thus only the most recently received ep0 request will get a
++ * status-stage response.
++ *
++ * Warning: This driver source file is too long.  It ought to be split up
++ * into a header file plus about 3 separate .c files, to handle the details
++ * of the Gadget, USB Mass Storage, and SCSI protocols.

++
++dwc_read_reg32() and friends now take an additional parameter, a pointer to an
++IO context struct. The IO context struct should live in an os-dependent struct
++in your driver. As an example, the dwc_usb3 driver has an os-dependent struct
++named 'os_dep' embedded in the main device struct. So there these calls look
++like this:
++
++	dwc_read_reg32(&usb3_dev->os_dep.ioctx, &pcd->dev_global_regs->dcfg);
++
++	dwc_write_reg32(&usb3_dev->os_dep.ioctx,
++			&pcd->dev_global_regs->dcfg, 0);
++
++Note that for the existing Linux driver ports, it is not necessary to actually
++define the 'ioctx' member in the os-dependent struct. Since Linux does not
++require an IO context, its macros for dwc_read_reg32() and friends do not
++use the context pointer, so it is optimized away by the compiler. But it is
++necessary to add the pointer parameter to all of the call sites, to be ready
++for any future ports (such as FreeBSD) which do require an IO context.
++
++
++Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now
++take an additional parameter, a pointer to a memory context. Examples:
++
++	addr = dwc_alloc(&usb3_dev->os_dep.memctx, size);
++
++	dwc_free(&usb3_dev->os_dep.memctx, addr);
++
++Again, for the Linux ports, it is not necessary to actually define the memctx
++member, but it is necessary to add the pointer parameter to all of the call
++sites.
++
++
++Same for dwc_dma_alloc() and dwc_dma_free(). Examples:
++
++	virt_addr = dwc_dma_alloc(&usb3_dev->os_dep.dmactx, size, &phys_addr);
++
++	dwc_dma_free(&usb3_dev->os_dep.dmactx, size, virt_addr, phys_addr);
++
++
++Same for dwc_mutex_alloc() and dwc_mutex_free(). Examples:
++
++	mutex = dwc_mutex_alloc(&usb3_dev->os_dep.mtxctx);
++
++	dwc_mutex_free(&usb3_dev->os_dep.mtxctx, mutex);
++
++
++Same for dwc_spinlock_alloc() and dwc_spinlock_free(). Examples:
++
++	lock = dwc_spinlock_alloc(&usb3_dev->osdep.splctx);
++
++	dwc_spinlock_free(&usb3_dev->osdep.splctx, lock);
++
++
++Same for dwc_timer_alloc(). Example:
++
++	timer = dwc_timer_alloc(&usb3_dev->os_dep.tmrctx, "dwc_usb3_tmr1",
++				cb_func, cb_data);
++
++
++Same for dwc_waitq_alloc(). Example:
++
++	waitq = dwc_waitq_alloc(&usb3_dev->os_dep.wtqctx);
++
++
++Same for dwc_thread_run(). Example:
++
++	thread = dwc_thread_run(&usb3_dev->os_dep.thdctx, func,
++				"dwc_usb3_thd1", data);
++
++
++Same for dwc_workq_alloc(). Example:
++
++	workq = dwc_workq_alloc(&usb3_dev->osdep.wkqctx, "dwc_usb3_wkq1");
++
++
++Same for dwc_task_alloc(). Example:
++
++	task = dwc_task_alloc(&usb3_dev->os_dep.tskctx, "dwc_usb3_tsk1",
++			      cb_func, cb_data);
++
++
++In addition to the context pointer additions, a few core functions have had
++other changes made to their parameters:
++
++The 'flags' parameter to dwc_spinlock_irqsave() and dwc_spinunlock_irqrestore()
++has been changed from a uint64_t to a dwc_irqflags_t.
++
++dwc_thread_should_stop() now takes a 'dwc_thread_t *' parameter, because the
++FreeBSD equivalent of that function requires it.
++
++And, in addition to the context pointer, dwc_task_alloc() also adds a
++'char *name' parameter, to be consistent with dwc_thread_run() and
++dwc_workq_alloc(), and because the FreeBSD equivalent of that function
++requires a unique name.
++
++
++Here is a complete list of the core functions that now take a pointer to a
++context as their first parameter:
++
++	dwc_read_reg32
++	dwc_read_reg64
++	dwc_write_reg32
++	dwc_write_reg64
++	dwc_modify_reg32
++	dwc_modify_reg64
++	dwc_alloc
++	dwc_alloc_atomic
++	dwc_strdup
++	dwc_free
++	dwc_dma_alloc
++	dwc_dma_free
++	dwc_mutex_alloc
++	dwc_mutex_free
++	dwc_spinlock_alloc
++	dwc_spinlock_free
++	dwc_timer_alloc
++	dwc_waitq_alloc
++	dwc_thread_run
++	dwc_workq_alloc
++	dwc_task_alloc     Also adds a 'char *name' as its 2nd parameter
++
++And here are the core functions that have other changes to their parameters:
++
++	dwc_spinlock_irqsave      'flags' param is now a 'dwc_irqflags_t *'
++	dwc_spinunlock_irqrestore 'flags' param is now a 'dwc_irqflags_t'
++	dwc_thread_should_stop    Adds a 'dwc_thread_t *' parameter
++
++
++
++The changes to the core functions also require some of the other library
++functions to change:
++
++	dwc_cc_if_alloc() and dwc_cc_if_free() now take a 'void *memctx'
++	(for memory allocation) as the 1st param and a 'void *mtxctx'
++	(for mutex allocation) as the 2nd param.
++
++	dwc_cc_clear(), dwc_cc_add(), dwc_cc_change(), dwc_cc_remove(),
++	dwc_cc_data_for_save(), and dwc_cc_restore_from_data() now take a
++	'void *memctx' as the 1st param.
++
++	dwc_dh_modpow(), dwc_dh_pk(), and dwc_dh_derive_keys() now take a
++	'void *memctx' as the 1st param.
++
++	dwc_modpow() now takes a 'void *memctx' as the 1st param.
++
++	dwc_alloc_notification_manager() now takes a 'void *memctx' as the
++	1st param and a 'void *wkqctx' (for work queue allocation) as the 2nd
++	param, and also now returns an integer value that is non-zero if
++	allocation of its data structures or work queue fails.
++
++	dwc_register_notifier() now takes a 'void *memctx' as the 1st param.
++
++	dwc_memory_debug_start() now takes a 'void *mem_ctx' as the first
++	param, and also now returns an integer value that is non-zero if
++	allocation of its data structures fails.
++
++
++
++Other miscellaneous changes:
++
++The DEBUG_MEMORY and DEBUG_REGS #define's have been renamed to
++DWC_DEBUG_MEMORY and DWC_DEBUG_REGS.
++
++The following #define's have been added to allow selectively compiling library
++features:
++
++	DWC_CCLIB
++	DWC_CRYPTOLIB
++	DWC_NOTIFYLIB
++	DWC_UTFLIB
++
++A DWC_LIBMODULE #define has also been added. If this is not defined, then the
++module code in dwc_common_linux.c is not compiled in. This allows linking the
++library code directly into a driver module, instead of as a standalone module.

++/*
++ * This file defines five types of data structures: singly-linked lists,
++ * lists, simple queues, tail queues, and circular queues.
++ *
++ *
++ * A singly-linked list is headed by a single forward pointer. The elements
++ * are singly linked for minimum space and pointer manipulation overhead at
++ * the expense of O(n) removal for arbitrary elements. New elements can be
++ * added to the list after an existing element or at the head of the list.
++ * Elements being removed from the head of the list should use the explicit
++ * macro for this purpose for optimum efficiency. A singly-linked list may
++ * only be traversed in the forward direction.  Singly-linked lists are ideal
++ * for applications with large datasets and few or no removals or for
++ * implementing a LIFO queue.
++ *
++ * A list is headed by a single forward pointer (or an array of forward
++ * pointers for a hash table header). The elements are doubly linked
++ * so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before
++ * or after an existing element or at the head of the list. A list
++ * may only be traversed in the forward direction.
++ *
++ * A simple queue is headed by a pair of pointers, one the head of the
++ * list and the other to the tail of the list. The elements are singly
++ * linked to save space, so elements can only be removed from the
++ * head of the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the
++ * list. A simple queue may only be traversed in the forward direction.
++ *
++ * A tail queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or
++ * after an existing element, at the head of the list, or at the end of
++ * the list. A tail queue may be traversed in either direction.
++ *
++ * A circle queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the list.
++ * A circle queue may be traversed in either direction, but has a more
++ * complex end of list detection.
++ *
++ * For details on the use of these macros, see the queue(3) manual page.

++/** @file
++ *
++ * A simple implementation of the Observer pattern.  Any "module" can
++ * register as an observer or notifier.  The notion of "module" is abstract and
++ * can mean anything used to identify either an observer or notifier.  Usually
++ * it will be a pointer to a data structure which contains some state, ie an
++ * object.
++ *
++ * Before any notifiers can be added, the global notification manager must be
++ * brought up with dwc_alloc_notification_manager().
++ * dwc_free_notification_manager() will bring it down and free all resources.
++ * These would typically be called upon module load and unload.  The
++ * notification manager is a single global instance that handles all registered
++ * observable modules and observers so this should be done only once.
++ *
++ * A module can be observable by using Notifications to publicize some general
++ * information about it's state or operation.  It does not care who listens, or
++ * even if anyone listens, or what they do with the information.  The observable
++ * modules do not need to know any information about it's observers or their
++ * interface, or their state or data.
++ *
++ * Any module can register to emit Notifications.  It should publish a list of
++ * notifications that it can emit and their behavior, such as when they will get
++ * triggered, and what information will be provided to the observer.  Then it
++ * should register itself as an observable module. See dwc_register_notifier().
++ *
++ * Any module can observe any observable, registered module, provided it has a
++ * handle to the other module and knows what notifications to observe.  See
++ * dwc_add_observer().
++ *
++ * A function of type dwc_notifier_callback_t is called whenever a notification
++ * is triggered with one or more observers observing it.  This function is
++ * called in it's own process so it may sleep or block if needed.  It is
++ * guaranteed to be called sometime after the notification has occurred and will
++ * be called once per each time the notification is triggered.  It will NOT be
++ * called in the same process context used to trigger the notification.
++ *
++ * @section Limitiations
++ *
++ * Keep in mind that Notifications that can be triggered in rapid sucession may
++ * schedule too many processes too handle.  Be aware of this limitation when
++ * designing to use notifications, and only add notifications for appropriate
++ * observable information.
++ *
++ * Also Notification callbacks are not synchronous.  If you need to synchronize
++ * the behavior between module/observer you must use other means.  And perhaps
++ * that will mean Notifications are not the proper solution.

++/* @mainpage DWC Portability and Common Library
++ *
++ * This is the documentation for the DWC Portability and Common Library.
++ *
++ * @section intro Introduction
++ *
++ * The DWC Portability library consists of wrapper calls and data structures to
++ * all low-level functions which are typically provided by the OS.  The WUDEV
++ * driver uses only these functions.  In order to port the WUDEV driver, only
++ * the functions in this library need to be re-implemented, with the same
++ * behavior as documented here.
++ *
++ * The Common library consists of higher level functions, which rely only on
++ * calling the functions from the DWC Portability library.  These common
++ * routines are shared across modules.  Some of the common libraries need to be
++ * used directly by the driver programmer when porting WUDEV.  Such as the
++ * parameter and notification libraries.
++ *
++ * @section low Portability Library OS Wrapper Functions
++ *
++ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
++ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC().  All of
++ * these functions are included in the dwc_os.h file.
++ *
++ * There are many functions here covering a wide array of OS services.  Please
++ * see dwc_os.h for details, and implementation notes for each function.
++ *
++ * @section common Common Library Functions
++ *
++ * Any function starting with dwc and in all lowercase is a common library
++ * routine.  These functions have a portable implementation and do not need to
++ * be reimplemented when porting.  The common routines can be used by any
++ * driver, and some must be used by the end user to control the drivers.  For
++ * example, you must use the Parameter common library in order to set the
++ * parameters in the WUDEV module.
++ *
++ * The common libraries consist of the following:
++ *
++ * - Connection Contexts - Used internally and can be used by end-user.  See dwc_cc.h
++ * - Parameters - Used internally and can be used by end-user.  See dwc_params.h
++ * - Notifications - Used internally and can be used by end-user.  See dwc_notifier.h
++ * - Lists - Used internally and can be used by end-user.  See dwc_list.h
++ * - Memory Debugging - Used internally and can be used by end-user.  See dwc_os.h
++ * - Modpow - Used internally only.  See dwc_modpow.h
++ * - DH - Used internally only.  See dwc_dh.h
++ * - Crypto - Used internally only.  See dwc_crypto.h
++ *
++ *
++ * @section prereq Prerequistes For dwc_os.h
++ * @subsection types Data Types
++ *
++ * The dwc_os.h file assumes that several low-level data types are pre defined for the
++ * compilation environment.  These data types are:
++ *
++ * - uint8_t - unsigned 8-bit data type
++ * - int8_t - signed 8-bit data type
++ * - uint16_t - unsigned 16-bit data type
++ * - int16_t - signed 16-bit data type
++ * - uint32_t - unsigned 32-bit data type
++ * - int32_t - signed 32-bit data type
++ * - uint64_t - unsigned 64-bit data type
++ * - int64_t - signed 64-bit data type
++ *
++ * Ensure that these are defined before using dwc_os.h.  The easiest way to do
++ * that is to modify the top of the file to include the appropriate header.
++ * This is already done for the Linux environment.  If the DWC_LINUX macro is
++ * defined, the correct header will be added.  A standard header <stdint.h> is
++ * also used for environments where standard C headers are available.
++ *
++ * @subsection stdarg Variable Arguments
++ *
++ * Variable arguments are provided by a standard C header <stdarg.h>.  it is
++ * available in Both the Linux and ANSI C enviornment.  An equivalent must be
++ * provided in your enviornment in order to use dwc_os.h with the debug and
++ * tracing message functionality.
++ *
++ * @subsection thread Threading
++ *
++ * WUDEV Core must be run on an operating system that provides for multiple
++ * threads/processes.  Threading can be implemented in many ways, even in
++ * embedded systems without an operating system.  At the bare minimum, the
++ * system should be able to start any number of processes at any time to handle

++ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't

++ *
++ * Use it with the Linux host/master side "usbtest" driver to get a basic
++ * functional test of your device-side usb stack, or with "usb-skeleton".
++ *
++ * It supports two similar configurations.  One sinks whatever the usb host
++ * writes, and in return sources zeroes.  The other loops whatever the host
++ * writes back, so the host can read it.  Module options include:
++ *
++ *   buflen=N		default N=4096, buffer size used
++ *   qlen=N		default N=32, how many buffers in the loopback queue
++ *   loopdefault	default false, list loopback config first
++ *
++ * Many drivers will only have one configuration, letting them be much
++ * simpler if they also don't support high speed operation (like this
++ * driver does).

++ * The Core Interface Layer provides basic services for accessing and
++ * managing the DWC_otg hardware. These services are used by both the
++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.
++ * - The OS services used will be abstracted by using inline functions
++ *	 or macros.

++/** @file
++ * The dwc_otg_driver module provides the initialization and cleanup entry
++ * points for the DWC_otg driver. This module will be dynamically installed
++ * after Linux is booted using the insmod command. When the module is
++ * installed, the dwc_otg_driver_init function is called. When the module is
++ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
++ *
++ * This module also defines a data structure for the dwc_otg_driver, which is
++ * used in conjunction with the standard ARM lm_device structure. These
++ * structures allow the OTG driver to comply with the standard Linux driver
++ * model in which devices and drivers are registered with a bus driver. This
++ * has the benefit that Linux can expose attributes of the driver and device
++ * in its special sysfs file system. Users can then read or write files in
++ * this file system to perform diagnostics on the driver components or the
++ * device.

++ * This FIQ implements functionality that performs split transactions on
++ * the dwc_otg hardware without any outside intervention. A split transaction
++ * is "queued" by nominating a specific host channel to perform the entirety
++ * of a split transaction. This FIQ will then perform the microframe-precise
++ * scheduling required in each phase of the transaction until completion.
++ *
++ * The FIQ functionality is glued into the Synopsys driver via the entry point
++ * in the FSM enqueue function, and at the exit point in handling a HC interrupt
++ * for a FSM-enabled channel.
++ *
++ * NB: Large parts of this implementation have architecture-specific code.
++ * For porting this functionality to other ARM machines, the minimum is required:
++ * - An interrupt controller allowing the top-level dwc USB interrupt to be routed
++ *   to the FIQ
++ * - A method of forcing a software generated interrupt from FIQ mode that then
++ *   triggers an IRQ entry (with the dwc USB handler called by this IRQ number)
++ * - Guaranteed interrupt routing such that both the FIQ and SGI occur on the same
++ *   processor core - there is no locking between the FIQ and IRQ (aside from
++ *   local_fiq_disable)

++ * the dwc_otg hardware without any outside intervention. A split transaction
++ * is "queued" by nominating a specific host channel to perform the entirety
++ * of a split transaction. This FIQ will then perform the microframe-precise
++ * scheduling required in each phase of the transaction until completion.
++ *
++ * The FIQ functionality has been surgically implanted into the Synopsys
++ * vendor-provided driver.

++ * This file contains the data structures for accessing the DWC_otg core registers.
++ *
++ * The application interfaces with the HS OTG core by reading from and
++ * writing to the Control and Status Register (CSR) space through the
++ * AHB Slave interface. These registers are 32 bits wide, and the
++ * addresses are 32-bit-block aligned.
++ * CSRs are classified as follows:
++ * - Core Global Registers
++ * - Device Mode Registers
++ * - Device Global Registers
++ * - Device Endpoint Specific Registers
++ * - Host Mode Registers
++ * - Host Global Registers
++ * - Host Port CSRs
++ * - Host Channel Specific Registers
++ *
++ * Only the Core Global registers can be accessed in both Device and
++ * Host modes. When the HS OTG core is operating in one mode, either
++ * Device or Host, the application must not access registers from the
++ * other mode. When the core switches from one mode to another, the
++ * registers in the new mode of operation must be reprogrammed as they
++ * would be after a power-on reset.

+bcm2708_fb : Implement blanking support using the mailbox property interface
+
+bcm2708_fb: Add pan and vsync controls
+
+bcm2708_fb: DMA acceleration for fb_copyarea
+
+Based on http://www.raspberrypi.org/phpBB3/viewtopic.php?p=62425#p62425
+Also used Simon's dmaer_master module as a reference for tweaking DMA
+settings for better performance.
+
+For now busylooping only. IRQ support might be added later.
+With non-overclocked Raspberry Pi, the performance is ~360 MB/s
+for simple copy or ~260 MB/s for two-pass copy (used when dragging
+windows to the right).
+
+In the case of using DMA channel 0, the performance improves
+to ~440 MB/s.
+
+For comparison, VFP optimized CPU copy can only do ~114 MB/s in
+the same conditions (hindered by reading uncached source buffer).

+bcm2708_fb: report number of dma copies
+
+Add a counter (exported via debugfs) reporting the
+number of dma copies that the framebuffer driver
+has done, in order to help evaluate different
+optimization strategies.

+
+bcm2708_fb: use IRQ for DMA copies
+
+The copyarea ioctl() uses DMA to speed things along. This
+was busy-waiting for completion. This change supports using
+an interrupt instead for larger transfers. For small
+transfers, busy-waiting is still likely to be faster.

+
+Add Device Tree support.

+Use the new DMA legacy API header file.
+Including <mach/platform.h> is not necessary.

+Cleanup of bcm2708_fb file to kernel coding standards

+video: bcm2708_fb: Try allocating on the ARM and passing to VPU
+
+Currently the VPU allocates the contiguous buffer for the
+framebuffer.
+Try an alternate path first where we use dma_alloc_coherent
+and pass the buffer to the VPU. Should the VPU firmware not
+support that path, then free the buffer and revert to the
+old behaviour of using the VPU allocation.

+
+Based on the patch authored by Ali Gholami Rudi at
+    https://lkml.org/lkml/2009/7/13/153
+
+Provide an ioctl for userspace applications, but only if this operation

+video: bcm2708_fb: Disable FB if no displays found
+
+If the firmware hasn't detected a display, the driver would assume
+one display was available, but because it had failed to retrieve the
+display size it would try to allocate a zero-sized buffer.
+
+Avoid the allocation failure by bailing out early if no display is
+found.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add support for DMA controller of BCM2708 as used in the Raspberry Pi.
+Currently it only supports cyclic DMA.

+
+dmaengine: expand functionality by supporting scatter/gather transfers sdhci-bcm2708 and dma.c: fix for LITE channels
+
+DMA: fix cyclic LITE length overflow bug
+
+dmaengine: bcm2708: Remove chancnt affectations
+
+Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
+chancnt is already filled by dma_async_device_register, which uses the channel
+list to know how much channels there is.
+
+Since it's already filled, we can safely remove it from the drivers' probe
+function.

+
+dmaengine: bcm2708: overwrite dreq only if it is not set
+
+dreq is set when the DMA channel is fetched from Device Tree.
+slave_id is set using dmaengine_slave_config().
+Only overwrite dreq with slave_id if it is not set.
+
+dreq/slave_id in the cyclic DMA case is not touched, because I don't
+have hardware to test with.

+Add Device Tree support to the non ARCH_BCM2835 case.
+Use the same driver name regardless of architecture.

+BCM270x_DT: add bcm2835-dma entry
+
+Add Device Tree entry for bcm2835-dma.

+In non-DT mode, don't add the device in the board file.

+BCM270x: Add memory and irq resources to dmaengine device and DT
+
+Prepare for merging of the legacy DMA API arch driver dma.c

+to platform file device and Device Tree node.
+Don't use BCM_DMAMAN_DRIVER_NAME so we don't have to include mach/dma.h

+
+dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
+
+Merge the legacy DMA API driver with bcm2708-dmaengine.
+This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
+driver is also needed).
+
+Changes to the dma.c code:
+- Use BIT() macro.
+- Cutdown some comments to one line.
+- Add mutex to vc_dmaman and use this, since the dev lock is locked
+  during probing of the engine part.
+- Add global g_dmaman variable since drvdata is used by the engine part.
+- Restructure for readability:
+  vc_dmaman_chan_alloc()
+  vc_dmaman_chan_free()
+  bcm_dma_chan_free()
+- Restructure bcm_dma_chan_alloc() to simplify error handling.
+- Use device irq resources instead of hardcoded bcm_dma_irqs table.
+- Remove dev_dmaman_register() and code it directly.
+- Remove dev_dmaman_deregister() and code it directly.
+- Simplify bcm_dmaman_probe() using devm_* functions.
+- Get dmachans from DT if available.
+- Keep 'dma.dmachans' module argument name for backwards compatibility.
+
+Make it available on ARCH_BCM2835 as well.

+dmaengine: bcm2708: set residue_granularity field
+
+bcm2708-dmaengine supports residue reporting at burst level
+but didn't report this via the residue_granularity field.
+
+Without this field set properly we get playback issues with I2S cards.
+
+dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
+
+bcm2708-dmaengine: Use more DMA channels (but not 12)
+
+1) Only the bcm2708_fb drivers uses the legacy DMA API, and
+it requires a BULK-capable channel, so all other types
+(FAST, NORMAL and LITE) can be made available to the regular
+DMA API.
+
+2) DMA channels 11-14 share an interrupt. The driver can't
+handle this, so don't use channels 12-14 (12 was used, probably
+because it appears to have an interrupt, but in reality that
+interrupt is for activity on ANY channel). This may explain
+a lockup encountered when running out of DMA channels.
+
+The combined effect of this patch is to leave 7 DMA channels
+available + channel 0 for bcm2708_fb via the legacy API.
+
+See: https://github.com/raspberrypi/linux/issues/1110

+
+dmaengine: bcm2708: Make legacy API available for bcm2835-dma
+
+bcm2708_fb uses the legacy DMA API, so in order to start using
+bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
+possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().

+
+dmaengine: bcm2708: Change DT compatible string
+
+Both bcm2835-dma and bcm2708-dmaengine have the same compatible string.
+So change compatible to "brcm,bcm2708-dma".
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+dmaengine: bcm2708: Remove driver but keep legacy API
+
+Dropping non-DT support means we don't need this driver,
+but we still need the legacy DMA API.

+bcm2708-dmaengine - Fix arm64 portability/build issues
+
+dma-bcm2708: Fix module compilation of CONFIG_DMA_BCM2708
+
+bcm2708-dmaengine.c defines functions like bcm_dma_start which are
+defined as well in dma-bcm2708.h as inline versions when
+CONFIG_DMA_BCM2708 is not defined. This works fine when
+CONFIG_DMA_BCM2708 is built in, but when it is selected as module build
+fails with redefinition errors because in the build system when
+CONFIG_DMA_BCM2708 is selected as module, the macro becomes
+CONFIG_DMA_BCM2708_MODULE.
+
+This patch makes the header use CONFIG_DMA_BCM2708_MODULE too when
+available.

+bcm2708-dmaengine: Use platform_get_irq
+
+The platform driver framework no longer creates IRQ resources for
+platform devices because they are expected to use platform_get_irq.
+This causes the bcm2808_fb acceleration to fail.
+
+Fix the problem by calling platform_get_irq as intended.

+bcm2835-mmc: Adding overclocking option
+
+Allow a different clock speed to be substitued for a requested 50MHz.
+This option is exposed using the "overclock_50" DT parameter.
+Note that the mmc interface is restricted to EVEN integer divisions of
+250MHz, and the highest sensible option is 63 (250/4 = 62.5), the
+next being 125 (250/2) which is much too high.
+
+Use at your own risk.
+
+bcm2835-mmc: Round up the overclock, so 62 works for 62.5Mhz
+
+Also only warn once for each overclock setting.

+preserved.
+
+bcm2835-mmc: Only claim one DMA channel
+
+With both MMC controllers enabled there are few DMA channels left. The
+bcm2835-mmc driver only uses DMA in one direction at a time, so it

+mmc/bcm2835: Recover from MMC_SEND_EXT_CSD
+
+If the user issues an "mmc extcsd read", the SD controller receives
+what it thinks is a SEND_IF_COND command with an unexpected data block.
+The resulting operations leave the FSM stuck in READWAIT, a state which
+persists until the MMC framework resets the controller, by which point
+the root filesystem is likely to have been unmounted.
+
+A less heavyweight solution is to detect the condition and nudge the
+FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
+
+N.B. This workaround was essentially discovered by accident and without
+a full understanding the inner workings of the controller, so it is
+fortunate that the "fix" only modifies error paths.

+bcm2835-mmc: Fix DMA channel leak
+
+The BCM2835 MMC host driver requests a DMA channel on probe but neglects
+to release the channel in the probe error path and on driver unbind.
+
+I'm seeing this happen on every boot of the Compute Module 3: On first
+driver probe, DMA channel 2 is allocated and then leaked with a "could
+not get clk, deferring probe" message. On second driver probe, channel 4
+is allocated.
+
+Fix it.

+bcm2835-mmc: Fix struct mmc_host leak on probe
+

+
+bcm2835-mmc: Fix duplicate free_irq() on remove
+
+The BCM2835 MMC host driver requests its interrupt as a device-managed
+resource, so the interrupt is automatically freed after the driver is
+unbound.
+
+However on driver unbind, bcm2835_mmc_remove() frees the interrupt
+explicitly to avoid invocation of the interrupt handler after driver
+structures have been torn down.
+
+The interrupt is thus freed twice, leading to a WARN splat in
+__free_irq().  Fix by not requesting the interrupt as a device-managed
+resource.

+Subject: [PATCH 058/697] mmc: block: Don't do single-sector reads during
+ recovery
+
+See https://github.com/raspberrypi/linux/issues/5019
+
+If an SD card has degraded performance such that IO operations time out
+then the MMC block layer will leak SG DMA mappings in the swiotlb during
+recovery. It retries the same SG and this causes the leak, as it is
+mapped twice - once in sdhci_pre_req() and again during single-block
+reads in sdhci_prepare_data().
+
+Resetting the card (including power-cycling if a regulator for vmmc is
+present) ought to be enough to recover a stuck state, so for now don't
+try single-block reads in the recovery path.

+Subject: [PATCH 059/697] Adding bcm2835-sdhost driver, and an overlay to
+ enable it
+
+BCM2835 has two SD card interfaces. This driver uses the other one.
+
+bcm2835-sdhost: Error handling fix, and code clarification
+
+bcm2835-sdhost: Adding overclocking option
+
+Allow a different clock speed to be substitued for a requested 50MHz.
+This option is exposed using the "overclock_50" DT parameter.
+Note that the sdhost interface is restricted to integer divisions of
+core_freq, and the highest sensible option for a core_freq of 250MHz
+is 84 (250/3 = 83.3MHz), the next being 125 (250/2) which is much too
+high.
+
+Use at your own risk.
+
+bcm2835-sdhost: Round up the overclock, so 62 works for 62.5Mhz
+
+Also only warn once for each overclock setting.
+
+bcm2835-sdhost: Improve error handling and recovery
+
+1) Expose the hw_reset method to the MMC framework, removing many
+   internal calls by the driver.
+
+2) Reduce overclock setting on error.
+
+3) Increase timeout to cope with high capacity cards.
+
+4) Add properties and parameters to control pio_limit and debug.
+
+5) Reduce messages at probe time.
+
+bcm2835-sdhost: Further improve overclock back-off
+
+bcm2835-sdhost: Clear HBLC for PIO mode
+
+Also update pio_limit default in overlay README.
+
+bcm2835-sdhost: Add the ERASE capability
+
+See: https://github.com/raspberrypi/linux/issues/1076
+
+bcm2835-sdhost: Ignore CRC7 for MMC CMD1
+
+It seems that the sdhost interface returns CRC7 errors for CMD1,
+which is the MMC-specific SEND_OP_COND. Returning these errors to
+the MMC layer causes a downward spiral, but ignoring them seems
+to be harmless.
+
+bcm2835-mmc/sdhost: Remove ARCH_BCM2835 differences
+
+The bcm2835-mmc driver (and -sdhost driver that copied from it)
+contains code to handle SDIO interrupts in a threaded interrupt
+handler rather than waking the MMC framework thread. The change
+follows a patch from Russell King that adds the facility as the
+preferred way of working.
+
+However, the new code path is only present in ARCH_BCM2835
+builds, which I have taken to be a way of testing the waters
+rather than making the change across the board; I can't see

+removing the old code paths.
+
+bcm2835-sdhost: Don't log timeout errors unless debug=1
+
+The MMC card-discovery process generates timeouts. This is
+expected behaviour, so reporting it to the user serves no purpose.
+Suppress the reporting of timeout errors unless the debug flag
+is on.
+
+bcm2835-sdhost: Add workaround for odd behaviour on some cards
+
+For reasons not understood, the sdhost driver fails when reading
+sectors very near the end of some SD cards. The problem could
+be related to the similar issue that reading the final sector
+of any card as part of a multiple read never completes, and the
+workaround is an extension of the mechanism introduced to solve
+that problem which ensures those sectors are always read singly.
+
+bcm2835-sdhost: Major revision
+
+This is a significant revision of the bcm2835-sdhost driver. It
+improves on the original in a number of ways:
+
+1) Through the use of CMD23 for reads it appears to avoid problems
+   reading some sectors on certain high speed cards.
+2) Better atomicity to prevent crashes.
+3) Higher performance.
+4) Activity logging included, for easier diagnosis in the event
+   of a problem.

+bcm2835-sdhost: Restore ATOMIC flag to PIO sg mapping
+
+Allocation problems have been seen in a wireless driver, and
+this is the only change which might have been responsible.
+
+SQUASH: bcm2835-sdhost: Only claim one DMA channel
+
+With both MMC controllers enabled there are few DMA channels left. The
+bcm2835-sdhost driver only uses DMA in one direction at a time, so it
+doesn't need to claim two channels.

+
+bcm2835-sdhost: Workaround for "slow" sectors
+
+Some cards have been seen to cause timeouts after certain sectors are
+read. This workaround enforces a minimum delay between the stop after
+reading one of those sectors and a subsequent data command.
+
+Using CMD23 (SET_BLOCK_COUNT) avoids this problem, so good cards will
+not be penalised by this workaround.

+bcm2835-sdhost: Firmware manages the clock divisor
+
+The bcm2835-sdhost driver hands control of the CDIV clock divisor
+register to matching firmware, allowing it to adjust to a changing
+core clock. This removes the need to use the performance governor or
+to enable io_is_busy on the on-demand governor in order to get the
+best SD performance.
+
+N.B. As SD clocks must be an integer divisor of the core clock, it is
+possible that the SD clock for "turbo" mode can be different (even
+lower) than "normal" mode.

+
+bcm2835-sdhost: Reset the clock in task context
+
+Since reprogramming the clock can now involve a round-trip to the
+firmware it must not be done at atomic context, and a tasklet
+is not a task.

+
+bcm2835-sdhost: Don't exit cmd wait loop on error
+
+The FAIL flag can be set in the CMD register before command processing
+is complete, leading to spurious "failed to complete" errors. This has
+the effect of promoting harmless CRC7 errors during CMD1 processing
+into errors that can delay and even prevent booting.
+
+Also:
+1) Convert the last KERN_ERROR message in the register dumping to
+   KERN_INFO.
+2) Remove an unnecessary reset call from  bcm2835_sdhost_add_host.

+Support underclocking of the SD bus in two ways:

+   parameter), and
+2. using the exiting sd_overclock parameter.
+
+The two methods differ slightly - in the former the MMC subsystem is
+aware of the underclocking, while in the latter it isn't - but the
+end results should be the same.

+mmc/bcm2835-sdhost: Recover from MMC_SEND_EXT_CSD
+
+If the user issues an "mmc extcsd read", the SD controller receives
+what it thinks is a SEND_IF_COND command with an unexpected data block.
+The resulting operations leave the FSM stuck in READWAIT, a state which
+persists until the MMC framework resets the controller, by which point
+the root filesystem is likely to have been unmounted.
+
+A less heavyweight solution is to detect the condition and nudge the
+FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
+
+N.B. This workaround was essentially discovered by accident and without
+a full understanding the inner workings of the controller, so it is
+fortunate that the "fix" only modifies error paths.

+Subject: [PATCH 060/697] vc_mem: Add vc_mem driver for querying firmware
+ memory addresses
+MIME-Version: 1.0

+BCM270x: Move vc_mem
+
+Make the vc_mem module available for ARCH_BCM2835 by moving it.
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+char: vc_mem: Fix up compat ioctls for 64bit kernel
+
+compat_ioctl wasn't defined, so 32bit user/64bit kernel
+always failed.
+VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size
+unsigned long, so the ioctl cmd changes between sizes.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vc_mem: Fix all coding style issues.
+
+Cleans up all checkpatch errors in vc_mem.c and vc_mem.h
+No functional change to the code.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vc_mem: Delete dead code
+
+There are no error exists once device_create has succeeded, and
+therefore no need to call device_destroy from vc_mem_init.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+char: broadcom: vc_mem: Fix preprocessor conditional
+
+Signed-off-by: Alexander Winkowski <dereference23@outlook.com>
+
+vc_mem: Add the DMA memcpy support from bcm2708_fb
+
+bcm2708_fb is disabled by the vc4-kms-v3d overlay, which means that the
+DMA memcpy support it provides is not available to allow vclog to read
+the VC logs from the top 16MB on Pi 2 and Pi 3. Add the code to the
+vc_mem driver, which will still be enabled.
+
+It ought to be possible to do a proper DMA_MEM_TO_MEM copy via the
+generic DMA customer API, but that can be a later step.

+The read and write functions did not use the correct pointer offset
+when dealing with an odd number of bytes after a DMA transfer. Also,
+only handle the remaining odd bytes if the DMA transfer completed
+successfully.

++- brcm,smi-clock-source: the clock source for clkman
++- brcm,smi-clock-divisor: the integer clock divisor for clkman
++- dmas: the dma controller phandle and the DREQ number (4 on a 2835)

+Subject: [PATCH 062/697] Add Chris Boot's i2c driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+i2c-bcm2708: fixed baudrate
+
+Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock).
+In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits.
+This resulted in incorrect setting of CDIV and higher baudrate than intended.
+Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz
+After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz
+The correct baudrate is shown in the log after the cdiv > 0xffff correction.
+
+Perform I2C combined transactions when possible
+
+Perform I2C combined transactions whenever possible, within the
+restrictions of the Broadcomm Serial Controller.
+
+Disable DONE interrupt during TA poll
+
+Prevent interrupt from being triggered if poll is missed and transfer
+starts and finishes.
+
+i2c: Make combined transactions optional and disabled by default
+
+i2c: bcm2708: add device tree support
+
+Add DT support to driver and add to .dtsi file.
+Setup pins in .dts file.
+i2c is disabled by default.

+
+bcm2708: don't register i2c controllers when using DT
+
+The devices for the i2c controllers are in the Device Tree.
+Only register devices when not using DT.
+
+Signed-off-by: Noralf Tronnes <notro@tronnes.org>
+
+I2C: Only register the I2C device for the current board revision
+
+i2c_bcm2708: Fix clock reference counting
+
+Fix grabbing lock from atomic context in i2c driver
+
+2 main changes:
+- check for timeouts in the bcm2708_bsc_setup function as indicated by this comment:
+      /* poll for transfer start bit (should only take 1-20 polls) */
+  This implies that the setup function can now fail so account for this everywhere it's called
+- Removed the clk_get_rate call from inside the setup function as it locks a mutex and that's not ok since we call it from under a spin lock.
+
+i2c-bcm2708: When using DT, leave the GPIO setup to pinctrl
+
+i2c-bcm2708: Increase timeouts to allow larger transfers
+
+Use the timeout value provided by the I2C_TIMEOUT ioctl when waiting
+for completion. The default timeout is 1 second.
+
+See: https://github.com/raspberrypi/linux/issues/260
+
+i2c-bcm2708/BCM270X_DT: Add support for I2C2
+
+The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
+use of this bus can break an attached display - use with caution.
+
+It is recommended to disable accesses by VideoCore by setting
+hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
+
+The interface is disabled by default - enable using the
+i2c2_iknowwhatimdoing DT parameter.
+
+bcm2708-spi: Don't use static pin configuration with DT
+
+Also remove superfluous error checking - the SPI framework ensures the
+validity of the chip_select value.
+
+i2c-bcm2708: Remove non-DT support
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.
+
+Fixes i2c_bcm2708: Write to FIFO correctly - v2 (#1574)
+
+* i2c: fix i2c_bcm2708: Clear FIFO before sending data
+
+Make sure FIFO gets cleared before trying to send
+data in case of a repeated start (COMBINED=Y).
+
+* i2c: fix i2c_bcm2708: Only write to FIFO when not full
+
+Check if FIFO can accept data before writing.
+To avoid a peripheral read on the last iteration of a loop,
+both bcm2708_bsc_fifo_fill and ~drain are changed as well.

+Subject: [PATCH 064/697] char: broadcom: Add vcio module
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add module for accessing the mailbox property channel through
+/dev/vcio. Was previously in bcm2708-vcio.
+
+Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
+
+char: vcio: Add compat ioctl handling
+
+There was no compat ioctl handler, so 32 bit userspace on a
+64 bit kernel failed as IOCTL_MBOX_PROPERTY used the size
+of char*.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+char: vcio: Fail probe if rpi_firmware is not found.
+
+Device Tree is now the only supported config mechanism, therefore
+uncomment the block of code that fails the probe if the
+firmware node can't be found.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+drivers: char: vcio: Use common compat header
+
+The definition of compat_ptr is now common for most platforms, but
+requires the inclusion of <linux/compat.h>.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+char: vcio: Rewrite as a firmware node child
+
+The old vcio driver is a simple character device that manually locates
+the firmware driver. Initialising it before the firmware driver causes
+a failure, and no retries are attempted.
+
+Rewrite vcio as a platform driver that depends on a DT node for its
+instantiation and the location of the firmware driver, making use of
+the miscdevice framework to reduce the code size.
+
+N.B. Using miscdevice changes the udev SUBSYSTEM string, so a change
+to the companion udev rule is required in order to continue to set
+the correct device permissions, e.g.:
+
+    KERNEL="vcio", GROUP="video", MODE="0660"
+
+See: https://github.com/raspberrypi/linux/issues/4620

+Subject: [PATCH 067/697] leds: Add the "input" trigger, for pwr_led
+
+The "input" trigger makes the associated GPIO an input.  This is to support
+the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
+
+N.B. pwr_led is not available on Model A or B boards.
+
+leds-gpio: Implement the brightness_get method
+
+The power LED uses some clever logic that means it is driven
+by a voltage measuring circuit when configured as input, otherwise
+it is driven by the GPIO output value. This patch wires up the
+brightness_get method for leds-gpio so that user-space can monitor
+the LED value via /sys/class/gpio/led1/brightness. Using the input
+trigger this returns an indication of the system power health,
+otherwise it is just whatever value the trigger has written most
+recently.
+
+See: https://github.com/raspberrypi/linux/issues/1064

+Subject: [PATCH 069/697] Improve __copy_to_user and __copy_from_user
+ performance
+
+Provide a __copy_from_user that uses memcpy. On BCM2708, use
+optimised memcpy/memmove/memcmp/memset implementations.
+
+arch/arm: Add mmiocpy/set aliases for memcpy/set
+
+See: https://github.com/raspberrypi/linux/issues/1082
+
+copy_from_user: CPU_SW_DOMAIN_PAN compatibility
+
+The downstream copy_from_user acceleration must also play nice with
+CONFIG_CPU_SW_DOMAIN_PAN.
+
+See: https://github.com/raspberrypi/linux/issues/1381

+
+Fix copy_from_user if BCM2835_FAST_MEMCPY=n
+
+The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
+changed the behaviour of arm_copy_from_user. The page pinning code
+is not safe on ARMv7 if LPAE & high memory is enabled and causes
+crashes which look like PTE corruption.
+
+Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
+which is really an ARMv6 / Pi1 optimization and not necessary on newer
+ARM processors.
+
+arm: fix mmap unlocks in uaccess_with_memcpy.c
+
+This is a regression that was added with the commit 192a4e923ef092924dd013e7326f2ec520ee4783 as of rpi-5.8.y, since that is when the move to the mmap locking API was introduced - d8ed45c5dcd455fc5848d47f86883a1b872ac0d0
+
+The issue is that when the patch to improve performance for the __copy_to_user and __copy_from_user functions were added for the Raspberry Pi, some of the mmaps were incorrectly mapped to write instead of read. This would cause a verity of issues, and in my case, prevent the booting of a squashfs filesystem on rpi-5.8-y and above. An example of the panic you would see from this can be seen at https://pastebin.com/raw/jBz5xCzL

+arch/arm: Add __memset alias to memset_rpi.S
+
+memset_rpi.S is an optimised memset implementation, but doesn't define
+__memset (which was just added to memset.S). As a result, building
+for the BCM2835 platform causes a link failure.
+
+Add __memset as yet another alias to our common implementation.

+
+drivers: Remove downstream SenseHAT core and joystick drivers
+
+Parts of a SenseHAT driver have been submitted upstream using the
+simple-i2c-mfd framework. The joystick driver has been merged.
+
+It's been noted that there are several issues with the downstream
+joystick and core drivers, so remove these in favour of the upstream
+approach, and fix up the FB driver to match.

+ASoC: Add prompt for ICS43432 codec

+Add IQaudIO Sound Card support for Raspberry Pi
+
+Set a limit of 0dB on Digital Volume Control
+
+The main volume control in the PCM512x DAC has a range up to
++24dB. This is dangerously loud and can potentially cause massive
+clipping in the output stages. Therefore this sets a sensible
+limit of 0dB for this control.
+
+Allow up to 24dB digital gain to be applied when using IQAudIO DAC+
+
+24db_digital_gain DT param can be used to specify that PCM512x
+codec "Digital" volume control should not be limited to 0dB gain,
+and if specified will allow the full 24dB gain.
+
+Modify IQAudIO DAC+ ASoC driver to set card/dai config from dt
+
+Add the ability to set the card name, dai name and dai stream name, from
+dt config.

+IQaudIO: auto-mute for AMP+ and DigiAMP+

+IQAudIO amplifier mute via GPIO22. Add dt params for "one-shot" unmute
+and auto mute.
+
+Revision 2, auto mute implementing HiassofT suggestion to mute/unmute
+using set_bias_level, rather than startup/shutdown....
+"By default DAPM waits 5 seconds (pmdown_time) before shutting down
+playback streams so a close/stop immediately followed by open/start
+doesn't trigger an amp mute+unmute."
+
+Tested on both AMP+ (via DAC+) and DigiAMP+, with both options...
+
+dtoverlay=iqaudio-dacplus,unmute_amp
+ "one-shot" unmute when kernel module loads.
+
+dtoverlay=iqaudio-dacplus,auto_mute_amp
+ Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
+ when ALSA device closed. (Re-opening the device within the 5 second close
+ window, will cancel mute.)
+
+Revision 4, using gpiod.
+
+Revision 5, clean-up formatting before adding mute code.
+ - Convert tab plus 4 space formatting to 2x tab
+ - Remove '// NOT USED' commented code
+
+Revision 6, don't attempt to "one-shot" unmute amp, unless card is
+successfully registered.

+Added support for HiFiBerry DAC+
+
+The driver is based on the HiFiBerry DAC driver. However HiFiBerry DAC+ uses
+a different codec chip (PCM5122), therefore a new driver is necessary.
+
+Add support for the HiFiBerry DAC+ Pro.
+
+The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators.

+An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame.
+
+Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+
+
+24db_digital_gain DT param can be used to specify that PCM512x
+codec "Digital" volume control should not be limited to 0dB gain,
+and if specified will allow the full 24dB gain.
+
+Add dt param to force HiFiBerry DAC+ Pro into slave mode
+

+with Pi as master for bit and frame clock.

+ASoC: pcm512x: revert downstream changes
+
+This partially reverts commit 185ea05465aac8bf02a0d2b2f4289d42c72870b7
+which was added by https://github.com/raspberrypi/linux/pull/1152
+
+The downstream pcm512x changes caused a regression, it broke normal
+use of the 24bit format with the codec, eg when using simple-audio-card.
+
+The actual bug with 24bit playback is the incorrect usage
+of physical_width in various drivers in the downstream tree
+which causes 24bit data to be transmitted with 32 clock
+cycles. So it's not the pcm512x that needs fixing, it's the
+soundcard drivers.

+New AudioInjector.net Pi soundcard with low jitter audio in and out.
+
+Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile.
+Adds the dts overlay and updates the Makefile and README.

+Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions.
+
+Added support for headphones, microphone and bclk_ratio settings.
+
+This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.

+Added driver for HiFiBerry Amp amplifier add-on board
+
+The driver contains a low-level hardware driver for the TAS5713 and the
+drivers for the Raspberry Pi I2S subsystem.
+
+TAS5713: return error if initialisation fails
+
+Existing TAS5713 driver logs errors during initialisation, but does not return
+an error code. Therefore even if initialisation fails, the driver will still be
+loaded, but won't work. This patch fixes this. I2C communication error will now
+reported correctly by a non-zero return code.
+
+HiFiBerry Amp: fix device-tree problems
+
+Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.
+
+According to 5713 pdf doc CLOCK_CTRL is a readonly status register, and it behaves so. Remove useless setting
+
+sound: pcm512x-codec: Adding 352.8kHz samplerate support
+
+sound/soc: only first codec is master in multicodec setup
+
+When using multiple codecs, at most one codec should generate the master
+clock. All codecs except the first are therefore configured for slave
+mode.

+Subject: [PATCH 075/697] bcm2835-virtgpio: Virtual GPIO driver
+
+Add a virtual GPIO driver that uses the firmware mailbox interface to
+request that the VPU toggles LEDs.
+
+gpio: bcm-virt: Fix the get() method
+
+The get() method does not understand the on-the-wire encoding of the
+remote GPIO states, thinking they are simple on/off bits when they are
+really pairs of 16-bit counts. Rewrite the get() handler to return the
+value last written, which will eventually match the actual GPIO state
+if there are no other changes.
+
+See: https://github.com/raspberrypi/linux/issues/4638

+
+bcm2835-virtgpio: Update for Linux 6.6
+
+The gpio subsystem is happier if the gpiochip is given a parent, and
+if it doesn't have a fixed base gpio number. While we're in here,
+use the fact that the firmware node is the parent to locate it,
+and use the devm_ version of rpi_firmware_get.

+Subject: [PATCH 076/697] OF: DT-Overlay configfs interface
+
+This is a port of Pantelis Antoniou's v3 port that makes use of the
+new upstreamed configfs support for binary attributes.
+
+Original commit message:
+
+Add a runtime interface to using configfs for generic device tree overlay
+usage. With it its possible to use device tree overlays without having
+to use a per-platform overlay manager.
+
+Please see Documentation/devicetree/configfs-overlays.txt for more info.
+
+Changes since v2:
+- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
+- Created a documentation entry
+- Slight rewording in Kconfig
+
+Changes since v1:
+- of_resolve() -> of_resolve_phandles().

++Howto use the configfs overlay interface.
++
++A device-tree configfs entry is created in /config/device-tree/overlays
++and and it is manipulated using standard file system I/O.
++Note that this is a debug level interface, for use by developers and
++not necessarily something accessed by normal users due to the
++security implications of having direct access to the kernel's device tree.
++
++* To create an overlay you mkdir the directory:
++
++	# mkdir /config/device-tree/overlays/foo
++
++* Either you echo the overlay firmware file to the path property file.
++
++	# echo foo.dtbo >/config/device-tree/overlays/foo/path
++
++* Or you cat the contents of the overlay to the dtbo file
++
++	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
++
++The overlay file will be applied, and devices will be created/destroyed
++as required.
++
++To remove it simply rmdir the directory.
++
++	# rmdir /config/device-tree/overlays/foo
++
++The rationalle of the dual interface (firmware & direct copy) is that each is
++better suited to different use patterns. The firmware interface is what's
++intended to be used by hardware managers in the kernel, while the copy interface
++make sense for developers (since it avoids problems with namespaces).

+Revert "brcmfmac: Disable power management"
+
+Shortly after the release of the Pi 3B, a loss of SSH connectivity
+over WiFi was traced to the power management handling, so power
+management was disabled. And so it has remained ever since.
+
+Enabling power management saves 55mA (~270mW) on a Pi 4B, so is very
+much worth the minimal effort of reverting this patch, which was
+squashed and rebased many times since then to the commit hash is
+meaningless.

+Subject: [PATCH 079/697] ARM64: Round-Robin dispatch IRQs between CPUs.
+
+IRQ-CPU mapping is round robined on ARM64 to increase

+at a time.  This reduces the need for FIQ.

+
+drivers: irqchip: irq-bcm2835: Concurrency fix
+
+The commit shown in Fixes: aims to improve interrupt throughput by
+getting the handlers invoked on different CPU cores. It does so (*) by
+using an irq_ack hook to change the interrupt routing.
+
+Unfortunately, the IRQ status bits must be cleared at source, which only
+happens once the interrupt handler has run - there is no easy way for
+one core to claim one of the IRQs before sending the remainder to the
+next core on the list, so waking another core immediately results in a
+race with a chance of both cores handling the same IRQ. It is probably
+for this reason that the routing change is deferred to irq_ack, but that
+doesn't guarantee no clashes - after irq_ack is called, control returns
+to bcm2836_chained_handler_irq which proceeds to check for other pending
+IRQs at a time when the next core is probably doing the same thing.
+
+Since the whole point of the original commit is to distribute the IRQ
+handling, there is no reason to attempt to handle multiple IRQs in one
+interrupt callback, so the problem can be solved (or at least made much
+harder to reproduce) by changing a "while" into an "if", so that each
+invocation only handles one IRQ.
+
+(*) I'm not convinced it's as effective as claimed since irq_ack is
+called _after_ the interrupt handler, but the author thought it made a
+difference.
+

+Create a semi-static mapping for the USB registers early in the boot
+process, before additional kernel threads are started, so all threads
+will have the mappings from the start. This avoids the need for

+I2C busses can be assigned specific bus numbers using aliases in
+Device Tree - string properties where the name is the alias and the
+value is the path to the node. The current DT parameter mechanism
+does not allow property names to be derived from a parameter value
+in any way, so it isn't possible to generate unique or matching
+aliases for nodes from an overlay that can generate multiple
+instances, e.g. i2c-gpio.
+
+Work around this limitation (at least temporarily) by allowing
+the i2c adapter number to be initialised from the "reg" property
+if present.

+Subject: [PATCH 089/697] irqchip: irq-bcm2835: Calc. FIQ_START at boot-time
+
+ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
+changed the way that the BCM2836/7 local interrupts are mapped; instead
+of being pre-mapped they are now mapped on-demand. A side effect of this
+change is that the call to irq_of_parse_and_map from armctrl_of_init
+creates a new mapping, forming a gap between the IRQs and the FIQs. This
+ gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
+
+1) that the value of FIQ_START is the same as the number of normal IRQs
+that will be mapped (still true), and
+
+2) that this value is also the offset between an IRQ and its equivalent
+FIQ (which is no longer the case).
+
+Remove both assumptions by measuring the interval between the last IRQ
+and the last FIQ, passing it as the parameter to init_FIQ().

+As of 4.18, a firmware that implements the update_connect_params

+Subject: [PATCH 094/697] net: lan78xx: Disable TCP Segmentation Offload (TSO)
+
+TSO seems to be having issues when packets are dropped and the
+remote end uses Selective Acknowledge (SACK) to denote that
+data is missing. The missing data is never resent, so the
+connection eventually stalls.
+
+There is a module parameter of enable_tso added to allow
+further debugging without forcing a rebuild of the kernel.

+
+Ethernet cables with faulty or missing pairs (specifically pairs C and
+D) allow auto-negotiation to 1000Mbs, but do not support the successful
+establishment of a link. Add a DT property, "microchip,downshift-after",
+to configure the number of auto-negotiation failures after which it
+falls back to 100Mbs. Valid values are 2, 3, 4, 5 and 0, where 0 means
+never downshift.

+The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
+that the driver pays attention to is "link was reset". If there's a
+flapping status bit in that endpoint data, (such as if PHY negotiation

+
+lan78xx_link_reset explicitly clears the MAC's view of the PHY's IRQ
+status. In doing so it potentially leaves the PHY with a pending
+interrupt that will never be acknowledged, at which point no further
+interrupts will be generated.
+
+Avoid the problem by acknowledging any pending PHY interrupt after

+Subject: [PATCH 102/697] media: tc358743: Check I2C succeeded during probe.
+
+The probe for the TC358743 reads the CHIPID register from
+the device and compares it to the expected value of 0.
+If the I2C request fails then that also returns 0, so
+the driver loads thinking that the device is there.
+
+Generally I2C communications are reliable so there is
+limited need to check the return value on every transfer,
+therefore only amend the one read during probe to check
+for I2C errors.

++Broadcom BCM283x Camera Interface (Unicam)
++------------------------------------------
++
++The Unicam block on BCM283x SoCs is the receiver for either
++CSI-2 or CCP2 data from image sensors or similar devices.
++
++The main platform using this SoC is the Raspberry Pi family of boards.
++On the Pi the VideoCore firmware can also control this hardware block,
++and driving it from two different processors will cause issues.
++To avoid this, the firmware checks the device tree configuration
++during boot. If it finds device tree nodes called csi0 or csi1 then
++it will stop the firmware accessing the block, and it can then
++safely be used via the device tree binding.
++
++Required properties:
++===================
++- compatible	: must be "brcm,bcm2835-unicam".
++- reg		: physical base address and length of the register sets for the
++		  device.
++- interrupts	: should contain the IRQ line for this Unicam instance.
++- clocks	: list of clock specifiers, corresponding to entries in
++		  clock-names property.
++- clock-names	: must contain an "lp" entry, matching entries in the
++		  clocks property.
++
++Unicam supports a single port node. It should contain one 'port' child node
++with child 'endpoint' node. Please refer to the bindings defined in
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Within the endpoint node the "remote-endpoint" and "data-lanes" properties
++are mandatory.
++Data lane reordering is not supported so the data lanes must be in order,
++starting at 1. The number of data lanes should represent the number of
++usable lanes for the hardware block. That may be limited by either the SoC or
++how the platform presents the interface, and the lower value must be used.
++
++Lane reordering is not supported on the clock lane either, so the optional
++property "clock-lane" will implicitly be <0>.
++Similarly lane inversion is not supported, therefore "lane-polarities" will
++implicitly be <0 0 0 0 0>.
++Neither of these values will be checked.
++
++Example:
++	csi1: csi1@7e801000 {
++		compatible = "brcm,bcm2835-unicam";
++		reg = <0x7e801000 0x800>,
++		      <0x7e802004 0x4>;
++		interrupts = <2 7>;
++		clocks = <&clocks BCM2835_CLOCK_CAM1>;
++		clock-names = "lp";
++
++		port {
++			csi1_ep: endpoint {
++				remote-endpoint = <&tc358743_0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};
++
++	i2c0: i2c@7e205000 {
++		tc358743: csi-hdmi-bridge@0f {
++			compatible = "toshiba,tc358743";
++			reg = <0x0f>;
++
++			clocks = <&tc358743_clk>;
++			clock-names = "refclk";
++
++			tc358743_clk: bridge-clk {
++				compatible = "fixed-clock";
++				#clock-cells = <0>;
++				clock-frequency = <27000000>;
++			};
++
++			port {
++				tc358743_0: endpoint {
++					remote-endpoint = <&csi1_ep>;
++					clock-lanes = <0>;
++					data-lanes = <1 2>;
++					clock-noncontinuous;
++					link-frequencies =
++						/bits/ 64 <297000000>;
++				};
++			};
++		};
++	};

+Subject: [PATCH 107/697] media: tc358743: Return an appropriate colorspace
+ from tc358743_set_fmt
+
+When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
+to choose a valid format. However that sets the colorspace
+based on what was read back from the chip. When you set the format,
+then the driver would choose and program the colorspace based
+on the format code.
+
+The result was that if you called try or set format for UYVY
+when the current format was RGB3 then you would get told sRGB,
+and try RGB3 when current was UYVY and you would get told
+SMPTE170M.
+
+The value programmed into the chip is determined by this driver,
+therefore there is no need to read back the value. Return the
+colorspace based on the format set/tried instead.

+Subject: [PATCH 109/697] staging: mmal-vchiq: Add support for event callbacks.
+
+(Preparation for the codec driver).
+The codec uses the event mechanism to report things such as
+resolution changes. It is signalled by the cmd field of the buffer
+being non-zero.
+
+Add support for passing this information out to the client.

+Subject: [PATCH 111/697] media: videobuf2: Allow exporting of a struct dmabuf
+
+videobuf2 only allowed exporting a dmabuf as a file descriptor,
+but there are instances where having the struct dma_buf is
+useful within the kernel.
+
+Split the current implementation into two, one step which
+exports a struct dma_buf, and the second which converts that
+into an fd.

+Subject: [PATCH 112/697] staging: mmal-vchiq: Fix client_component for 64 bit
+ kernel
+
+The MMAL client_component field is used with the event
+mechanism to allow the client to identify the component for
+which the event is generated.
+The field is only 32bits in size, therefore we can't use a
+pointer to the component in a 64 bit kernel.
+
+Component handles are already held in an array per VCHI
+instance, so use the array index as the client_component handle
+to avoid having to create a new IDR for this purpose.

+
+On Pi 5, the link to RP1 will bounce in and out of L1 depending on
+inactivity timers at both the RC and EP end. Unfortunately for
+bitbashing 1-wire, this means that on an otherwise idle Pi 5 many of the
+reads/writes to GPIO registers are delayed by up to 8us which causes
+mis-sampling of read data and trashes write bits.
+
+By issuing dummy reads at a rate greater than the link inactivity
+timeout while spinning on a delay, PCIe stays in L0 which does not incur
+additional latency.

+Subject: [PATCH 118/697] arm: bcm2835: Fix FIQ early ioremap
+
+The ioremapping creates mappings within the vmalloc area. The
+equivalent early function, create_mapping, now checks that the
+requested explicit virtual address is between VMALLOC_START and
+VMALLOC_END. As there is no reason to have any correlation between
+the physical and virtual addresses, put the required mappings at
+VMALLOC_START and above.

+Subject: [PATCH 123/697] net: genet: enable link energy detect powerdown for
+ external PHYs
+
+There are several warts surrounding bcmgenet_mii_probe() as this
+function is called from ndo_open, but it's calling registration-type
+functions. The probe should be called at probe time and refactored
+such that the PHY device data can be extracted to limit the scope
+of this flag to Broadcom PHYs.
+
+For now, pass this flag in as it puts our attached PHY into a low-power
+state when disconnected.

+Subject: [PATCH 124/697] usb: add plumbing for updating interrupt endpoint
+ interval state
+
+xHCI caches device and endpoint data after the interface is configured,
+so an explicit command needs to be issued for any device driver wanting
+to alter the polling interval of an endpoint.
+
+Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
+called after calculating endpoint bandwidth requirements but before any
+URBs are submitted.
+
+If polling intervals are shortened, any bandwidth reservations are no
+longer valid but in practice polling intervals are only ever relaxed.
+
+Limit the scope to interrupt transfers for now.

+ endpoint state
+
+See https://github.com/raspberrypi/linux/issues/3981
+
+An unknown unsafe memory access can result in the ep_state variable
+in xhci_virt_ep being trampled with a stuck SET_DEQ_PENDING state
+despite successful completion of a Set TR Deq Pointer command.
+
+All URB enqueue/dequeue calls for the endpoint will fail in this state
+so no transfers are possible until the device is reconnected.
+
+As a workaround, clear the flag if we see it set and issue a new Set
+TR Deq command anyway - this should be harmless, as a prior Set TR Deq
+command will only have been issued in the Stopped state, and if the
+endpoint is Running then the controller is required to ignore it and
+respond with a Context State Error event TRB.

+Subject: [PATCH 130/697] drm/v3d: Clock V3D down when not in use.
+
+My various attempts at re-enabling runtime PM have failed, so just
+crank the clock down when V3D is idle to reduce power consumption.
+
+Signed-off-by: Eric Anholt <eric@anholt.net>
+
+drm/v3d: Plug dma_fence leak
+
+The irq_fence and done_fence are given a reference that is never
+released. The necessary dma_fence_put()s seem to have been
+deleted in error in an earlier commit.
+

+
+Signed-off-by: popcornmix <popcornmix@gmail.com>
+
+v3d_gem: Kick the clock so firmware knows we are using firmware clock interface
+
+Setting the v3d clock to low value allows firmware to handle dvfs in case
+where v3d hardware is not being actively used (e.g. console use).

+Subject: [PATCH 132/697] hid: usb: Add device quirks for Freeway Airmouse T3
+ and MX3
+
+These wireless mouse/keyboard combo remote control devices specify
+multiple "wheel" events in their report descriptors. The wheel events
+are incorrectly defined and apparently map to accelerometer data, leading
+to spurious mouse scroll events being generated at an extreme rate when
+the device is moved.
+
+As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask
+feeding the extra wheel events to the input subsystem.

+Subject: [PATCH 133/697] net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
+
+Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
+DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
+address. In the failure case, the Pi is left able to receive packets
+but not send them, suggesting that the MAC<->PHY link is getting into
+a bad state.
+
+It has been found empirically that skipping a reset step by the genet
+driver prevents the failures. No downsides have been discovered yet,
+and unlike the forced renegotiation it doesn't increase the time to
+get an IP address, so the workaround is enabled by default; add
+
+  genet.skip_umac_reset=n
+
+to the command line to disable it.

+
+Adds a driver for the 12MPix Sony IMX477 CSI2 sensor.
+Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
+currently only supports 2 lanes.
+
+The following Bayer modes are currently available:

+media: i2c: imx477: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the imx477 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (8, 16) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.
+
+This commit mirrors 543790f777ba1b3264c168c653db6d415e7c983f done for
+the imx219 sensor.

+media: i2c: imx477: Remove auto frame length adjusting
+
+The V4L2_CID_EXPOSURE_AUTO_PRIORITY was used to let the sensor control
+frame length (effectively framerate) based on the requested exposure
+time requested. Remove this feature as it is never used, and goes
+against how V4L2 likes to handle exposure and vblank controls.

+
+media: i2c: imx477: Add very long exposure control to the driver
+
+Add support for very long exposures by using the exposure multiplier
+register. Userland does not need to pass any additional controls to
+enable long exposures, it simply requests a larger vblank to extend the
+exposure control range appropriately.
+
+Currently, since hblank is fixed, a maximum of approximately 124 seconds
+of exposure time can be used. In a future change, hblank could also be
+controlled in userland to give over 200 seconds of exposure time.

+
+Save the format code in imx477_set_pad_format() when setting up a new

++  The Sony IMX519 is a 1/2.5-inch CMOS active pixel digital image sensor
++  with an active array size of 4656H x 3496V. It is programmable through
++  I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
++  Image data is sent through MIPI CSI-2, which is configured as either 2 or
++  4 data lanes.

++* Infineon irs1125 time of flight sensor
++
++The Infineon irs1125 is a time of flight digital image sensor with
++an active array size of 352H x 286V. It is programmable through I2C
++interface. The I2C address defaults to 0x3D, but can be reconfigured
++to address 0x3C or 0x41 via I2C commands. Image data is sent through
++MIPI CSI-2, which is configured as either 1 or 2 data lanes.
++
++Required Properties:
++- compatible: value should be "infineon,irs1125" for irs1125 sensor
++- reg: I2C bus address of the device
++- clocks: reference to the xclk input clock.
++- pwdn-gpios: reference to the GPIO connected to the reset pin.
++	      This is an active low signal to the iirs1125.
++
++The irs1125 device node should contain one 'port' child node with
++an 'endpoint' subnode. For further reading on port node refer to
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Endpoint node required properties for CSI-2 connection are:
++- remote-endpoint: a phandle to the bus receiver's endpoint node.
++- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
++- data-lanes: should be set to <1> or <1 2> (one or two lane CSI-2
++  supported)
++
++Example:
++	sensor@10 {
++		compatible = "infineon,irs1125";
++		reg = <0x3D>;
++		#address-cells = <1>;
++		#size-cells = <0>;
++		clocks = <&irs1125_clk>;
++		pwdn-gpios = <&gpio 5 0>;
++
++		irs1125_clk: camera-clk {
++			compatible = "fixed-clock";
++			#clock-cells = <0>;
++			clock-frequency = <26000000>;
++		};
++
++		port {
++			sensor_out: endpoint {
++				remote-endpoint = <&csiss_in>;
++				clock-lanes = <0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};

+media: irs1125: Atomic access to imager reconfiguration
+
+Instead of changing the exposure and framerate settings for all sequences,
+they can be changed for every sequence individually now. Therefore the
+IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
+IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.
+
+The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG
+is removed.

+media: irs1125: Keep HW in sync after imager reset
+
+When closing the video device, the irs1125 is put in power down state.
+To keep V4L2 ctrls and the HW in sync, v4l2_ctrl_handler_setup is
+called after power up.
+
+The compound ctrl IRS1125_CID_MOD_PLL however has a default value
+of all zeros, which puts the imager into a non responding state.
+Thus, this ctrl is not written by the driver into HW after power up.
+The userspace has to take care to write senseful data.

+Subject: [PATCH 157/697] net: phy: broadcom: Allow ethernet LED mode to be set
+ via device tree
+
+Add device tree entries and code to allow the specification of
+the lighting modes for the LED's on the ethernet connector.
+
+Signed-off-by: James Hughes <james.hughes@raspberrypi.org>
+
+net:phy:2711 Change the default ethernet LED actions
+
+This should return default behaviour back to that of previous
+releases.
+
+net: phy: broadcom: Make LEDs 3+4 shadow LEDs 1+2
+
+CM4 uses BCM54210PE, which supports 2 additional LEDs, choosing LED3
+for the amber LED because it shows activity by default (LED4 is not
+connected). However, this makes it uncontrollable by the eth_led<n>
+dtparams which target LEDs 1+2.
+
+Solve the problem by making LEDs 3+4 mirror LEDs 1+2 (which is much
+simpler than adding baseboard-specific overrides, but comes with a
+risk of making one of the LEDs redundant).
+

+
+BCM54213PE is an Ethernet PHY that supports PTP hardware timestamping.
+BCM54210PW ia another Ethernet PHY, but one without PTP support.
+Unfortunately the two PHYs return the same ID when queried, so some
+extra information is required to determine whether the PHY is PTP-
+capable.
+
+There are two Raspberry Pi products that use these PHYs - Pi 4B and
+CM4 - and fortunately they use different PHY addresses, so use that as
+a differentiator. Choose to treat a PHY with the same ID but another
+address as a BCM54210PE, which seems more common.

+
+The VCHIQ driver now loads the audio, camera, codec, and vc-sm
+drivers as platform drivers. However they were not being given
+the correct DMA configuration.
+
+Call of_dma_configure with the parent (VCHIQ) parameters to be

+
+staging: vchiq: Use the old dma controller for OF config on platform devices
+
+vchiq on Pi4 is no longer under the soc node, therefore it
+doesn't get the dma-ranges for the VPU.
+
+Switch to using the configuration of the old dma controller as
+that will set the dma-ranges correctly.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
+
+staging: vchiq_arm: Give vchiq children DT nodes
+
+vchiq kernel clients are now instantiated as platform drivers rather
+than using DT, but the children of the vchiq interface may still
+benefit from access to DT properties. Give them the option of a
+a sub-node of the vchiq parent for configuration and to allow
+them to be disabled.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+staging: vchiq_arm: Add 36-bit address support
+
+Conditional on a new compatible string, change the pagelist encoding
+such that the top 24 bits are the pfn, leaving 8 bits for run length
+(-1), giving a 36-bit address range.
+
+Manage the split between addresses for the VPU and addresses for the
+40-bit DMA controller with a dedicated DMA device pointer that on non-
+BCM2711 platforms is the same as the main VCHIQ device. This allows
+the VCHIQ node to stay in the usual place in the DT.

+
+staging: vchiq_arm: children inherit DMA config
+
+Although it is no longer necessary for vchiq's children to have a
+different DMA configuration to the parent, they do still need to
+explicitly to have their DMA configuration set - to be that of the
+parent.

+Subject: [PATCH 163/697] staging: vchiq_arm: Usa a DMA pool for small bulks
+
+During a bulk transfer we request a DMA allocation to hold the
+scatter-gather list.  Most of the time, this allocation is small
+(<< PAGE_SIZE), however it can be requested at a high enough frequency
+to cause fragmentation and/or stress the CMA allocator (think time
+spent in compaction here, or during allocations elsewhere).
+
+Implement a pool to serve up small DMA allocations, falling back
+to a coherent allocation if the request is greater than
+VCHIQ_DMA_POOL_SIZE.

+Subject: [PATCH 166/697] of: overlay: Correct symbol path fixups
+
+When symbols from overlays are added to the live tree their paths must
+be rebased. The translated symbol is normally the result of joining
+the fragment-relative path (with a leading "/") to the target path
+(either copied directly from the "target-path" property or resolved
+from the phandle). This translation fails when the target is the root
+node (a common case for Raspberry Pi overlays) because the resulting
+path starts with a double slash. For example, if target-path is "/" and
+the fragment adds a node called "newnode", the label associated with
+that node will be assigned the path "//newnode", which can't be found
+in the tree.
+
+Fix the failure case by explicitly replacing a target path of "/" with
+an empty string.

++Brcmstb PCIe Host Controller Device Tree Bindings
++
++Required Properties:
++- compatible
++  "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
++  "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
++  "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
++      the 7278).
++  "brcm,bcm7278-pcie"  -- for 7278 family ARM-based SOCs.
++
++- reg -- the register start address and length for the PCIe reg block.
++- interrupts -- two interrupts are specified; the first interrupt is for
++     the PCI host controller and the second is for MSI if the built-in
++     MSI controller is to be used.
++- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
++- #address-cells -- set to <3>.
++- #size-cells -- set to <2>.
++- #interrupt-cells: set to <1>.
++- interrupt-map-mask and interrupt-map, standard PCI properties to define the
++     mapping of the PCIe interface to interrupt numbers.
++- ranges: ranges for the PCI memory and I/O regions.
++- linux,pci-domain -- should be unique per host controller.
++
++Optional Properties:
++- clocks -- phandle of pcie clock.
++- clock-names -- set to "sw_pcie" if clocks is used.
++- dma-ranges -- Specifies the inbound memory mapping regions when
++     an "identity map" is not possible.
++- msi-controller -- this property is typically specified to have the
++     PCIe controller use its internal MSI controller.
++- msi-parent -- set to use an external MSI interrupt controller.
++- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
++- max-link-speed --  (integer) indicates desired generation of link:
++     1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).

++V4L2_PIX_FMT_NV21_COL128
++Formats with ½ horizontal and vertical chroma resolution. This format
++has two planes - one for luminance and one for chrominance. Chroma
++samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
++memory layout. The image is split into columns of 128 bytes wide rather than
++being in raster order.
++
++V4L2_PIX_FMT_NV12_10_COL128
++Follows the same pattern as ``V4L2_PIX_FMT_NV21_COL128`` with 128 byte, but is
++a 10bit format with 3 10-bit samples being packed into 4 bytes. Each 128 byte
++wide column therefore contains 96 samples.
++
++
++Description
++===========
++
++This is the two-plane versions of the YUV 4:2:0 format where data is
++grouped into 128 byte wide columns. The three components are separated into
++two sub-images or planes. The Y plane has one byte per pixel and pixels
++are grouped into 128 byte wide columns. The CbCr plane has the same width,
++in bytes, as the Y plane (and the image), but is half as tall in pixels.
++The chroma plane is also in 128 byte columns, reflecting 64 Cb and 64 Cr
++samples.
++
++The chroma samples for a column follow the luma samples. If there is any
++paddding, then that will be reflected via the selection API.
++The luma height must be a multiple of 2 lines.
++
++The normal bytesperline is effectively fixed at 128. However the format
++requires knowledge of the stride between columns, therefore the bytesperline
++value has been repurposed to denote the number of 128 byte long lines between
++the start of each column.
++
++**Byte Order.**

++V4L2_PIX_FMT_NV12_10_COL128 uses the same 128 byte column structure, but
++encodes 10-bit YUV.
++3 10-bit values are packed into 4 bytes as bits 9:0, 19:10, and 29:20, with
++bits 30 & 31 unused. For the luma plane, bits 9:0 are Y0, 19:10 are Y1, and
++29:20 are Y2. For the chroma plane the samples always come in pairs of Cr
++and Cb, so it needs to be considered 6 values packed in 8 bytes.

+Subject: [PATCH 171/697] RFC: media: Add media_request_{pin,unpin} API
+
+This is probably not the API we will want to add, but it
+should show what semantics are needed by drivers.
+
+The goal is to allow the OUTPUT (aka source) buffer and the
+controls associated to a request to be released from the request,
+and in particular return the OUTPUT buffer back to userspace,
+without signalling the media request fd.
+
+This is useful for devices that are able to pre-process
+the OUTPUT buffer, therefore able to release it before
+the decoding is finished. These drivers should signal
+the media request fd only after the CAPTURE buffer is done.

+
+staging: media: rpivid: Select MEDIA_CONTROLLER and MEDIA_CONTROLLER_REQUEST_API
+
+MEDIA_CONTROLLER_REQUEST_API is a hidden option. If rpivid depends on it,
+the user would need to first enable another driver that selects
+MEDIA_CONTROLLER_REQUEST_API, and only then rpivid would become available.
+
+By selecting it instead of depending on it, it becomes possible to enable
+rpivid without having to enable other potentially unnecessary drivers.

+media: rpivid: Add a Pass0 to accumulate slices and rework job finish
+
+Due to overheads in assembling controls and requests it is worth having
+the slice assembly phase separate from the h/w pass1 processing. Create
+a queue to service pass1 rather than have the pass1 finished callback
+trigger the next slice job.
+
+This requires a rework of the logic that splits up the buffer and
+request done events. This code contains two ways of doing that, we use
+Ezequiel Garcias <ezequiel@collabora.com> solution, but expect that
+in the future this will be handled by the framework in a cleaner manner.

+It is legitimate, though unusual, for an aux ent associated with a slot
+to be selected in phase 0 before a previous selection has been used and
+released in phase 2. Fix such that if the slot is found to be in use
+that the aux ent associated with it is reused rather than an new aux
+ent being created. This fixes a problem where when the first aux ent
+was released the second was lost track of.

+Subject: [PATCH 173/697] spi: Force CS_HIGH if GPIO descriptors are used
+
+Commit f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
+amended of_spi_parse_dt() to always set SPI_CS_HIGH for SPI slaves whose
+Chip Select is defined by a "cs-gpios" devicetree property.
+
+This change breaks drivers whose probe functions set the mode field of
+the spi_device because in doing so they clear the SPI_CS_HIGH flag.
+
+Fix by setting SPI_CS_HIGH in spi_setup (under the same conditions as
+in of_spi_parse_dt()).
+
+See also: 83b2a8fe43bd ("spi: spidev: Fix CS polarity if GPIO descriptors are used")
+
+Fixes: f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+SQUASH: spi: Demote SPI_CS_HIGH warning to KERN_DEBUG
+
+This warning is unavoidable from a client's perspective and
+doesn't indicate anything wrong (just surprising).
+
+SQUASH with "spi: use_gpio_descriptor fixup moved to spi_setup"

++Sensor Ancillary Metadata
++
++Description
++===========
++
++This format describes ancillary data generated by a camera sensor and
++transmitted over a stream on the camera bus. Sensor vendors generally have their
++own custom format for this ancillary data. Some vendors follow a generic
++CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
++<https://mipi.org/specifications/csi-2>`_
++
++The size of the embedded buffer is defined as a single line with a pixel width
++width specified in bytes. This is obtained by a call to the
++:c:type:`VIDIOC_SUBDEV_G_FMT` ioctl on the sensor subdevice where the ``pad``
++field in :c:type:`v4l2_subdev_format` is set to 1.  Note that this size is fixed
++and cannot be modified with a call to :c:type:`VIDIOC_SUBDEV_S_FMT`.

++BCM2835 ISP Driver
++==================
++
++Introduction
++------------
++
++The BCM2835 Image Sensor Pipeline (ISP) is a fixed function hardware pipeline
++for performing image processing operations.  Images are fed to the input
++of the ISP through memory frame buffers.  These images may be in various YUV,
++RGB, or Bayer formats.  A typical use case would have Bayer images obtained from
++an image sensor by the BCM2835 Unicam peripheral, written to a memory
++frame buffer, and finally fed into the input of the ISP.  Two concurrent output
++images may be generated in YUV or RGB format at different resolutions.
++Statistics output is also generated for Bayer input images.
++
++The bcm2835-isp driver exposes the following media pads as V4L2 device nodes:
++
++.. tabularcolumns:: |l|l|l|l|
++
++.. cssclass: longtable
++
++.. flat-table::
++
++    * - *Pad*
++      - *Direction*
++      - *Purpose*
++      - *Formats*
++
++    * - "bcm2835-isp0-output0"
++      - sink
++      - Accepts Bayer, RGB or YUV format frame buffers as input to the ISP HW
++        pipeline.

+Subject: [PATCH 180/697] gpiolib: Don't prevent IRQ usage of output GPIOs
+
+Upstream Linux deems using output GPIOs to generate IRQs as a bogus
+use case, even though the BCM2835 GPIO controller is capable of doing
+so. A number of users would like to make use of this facility, so
+disable the checks.

+Subject: [PATCH 182/697] media: bcm2835-unicam: Driver for CCP2/CSI2 camera
+ interface
+
+Add a driver for the Unicam camera receiver block on BCM283x processors.
+Compared to the bcm2835-camera driver present in staging, this driver
+handles the Unicam block only (CSI-2 receiver), and doesn't depend on
+the VC4 firmware running on the VPU.
+
+The commit is made up of a series of changes cherry-picked from the
+rpi-5.4.y branch of https://github.com/raspberrypi/linux/ with
+additional enhancements, forward-ported to the mainline kernel.

++	  Say Y here to enable support for the BCM283x/BCM271x CSI-2 receiver.
++	  This is a V4L2 driver that controls the CSI-2 receiver directly,
++	  independently from the VC4 firmware.
++	  This driver is mutually exclusive with the use of bcm2835-camera. The
++	  firmware will disable all access to the peripheral from within the
++	  firmware if it finds a DT node using it, and bcm2835-camera will
++	  therefore fail to probe.
++
++	  To compile this driver as a module, choose M here. The module will be
++	  called bcm2835-unicam.

++ * BCM2835 Unicam Capture Driver
++ *
++ * Copyright (C) 2017-2020 - Raspberry Pi (Trading) Ltd.
++ *
++ * Dave Stevenson <dave.stevenson@raspberrypi.com>
++ *
++ * Based on TI am437x driver by
++ *   Benoit Parrot <bparrot@ti.com>
++ *   Lad, Prabhakar <prabhakar.csengg@gmail.com>
++ *
++ * and TI CAL camera interface driver by
++ *    Benoit Parrot <bparrot@ti.com>
++ *
++ *
++ * There are two camera drivers in the kernel for BCM283x - this one
++ * and bcm2835-camera (currently in staging).
++ *
++ * This driver directly controls the Unicam peripheral - there is no
++ * involvement with the VideoCore firmware. Unicam receives CSI-2 or
++ * CCP2 data and writes it into SDRAM.
++ * The only potential processing options are to repack Bayer data into an
++ * alternate format, and applying windowing.
++ * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P
++ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
++ * but not generically up to V4L2_PIX_FMT_Sxxxx16. The driver will add both
++ * formats where the relevant formats are defined, and will automatically
++ * configure the repacking as required.
++ * Support for windowing may be added later.
++ *
++ * It should be possible to connect this driver to any sensor with a
++ * suitable output interface and V4L2 subdevice driver.
++ *
++ * bcm2835-camera uses the VideoCore firmware to control the sensor,
++ * Unicam, ISP, and all tuner control loops. Fully processed frames are
++ * delivered to the driver by the firmware. It only has sensor drivers
++ * for Omnivision OV5647, and Sony IMX219 sensors.
++ *
++ * The two drivers are mutually exclusive for the same Unicam instance.
++ * The VideoCore firmware checks the device tree configuration during boot.
++ * If it finds device tree nodes called csi0 or csi1 it will block the
++ * firmware from accessing the peripheral, and bcm2835-camera will
++ * not be able to stream data.

+ alias
+
+Pi 0&1 pass all ARM accesses through the VPU L2 cache, therefore
+the dma-ranges property sets the cache alias bits to other
+than the direct alias, hence this WARN was firing.
+
+It was overprotective coding, so assume that everything is OK
+with the dma-ranges, and remove the WARN.

+Subject: [PATCH 192/697] media: bcm2835-unicam: Always service interrupts
+
+From when bringing up the driver, there was a check in the isr
+to ignore interrupts (claiming them handled) should the driver
+not be streaming.
+
+The VPU now will not register a camera driver if it finds a
+CSI2 node enabled in device tree, therefore this flawed check is
+redundant.

+
+The change to retrieve the pixel format always on g_fmt didn't
+check whether the native or unpacked version of the format
+had been requested, and always returned the packed one.
+Correct this so that the packing setting is retained whereever
+possible.

+Subject: [PATCH 196/697] media: bcm2835-unicam: change minimum number of
+ vb2_queue buffers to 1
+
+Since the unicam driver was modified to write to a dummy buffer when no
+user-supplied buffer is available, it can now write to and return a
+buffer even when there's only a single one. Enable this by changing the
+min_buffers_needed in the vb2_queue; it will be useful for enabling
+still captures without allocating more memory than absolutely necessary.

+Subject: [PATCH 197/697] staging/fbtft: Add support for display variants
+
+Display variants are intended as a replacement for the now-deleted
+fbtft_device drivers. Drivers can register additional compatible
+strings with a custom callback that can make the required changes
+to the fbtft_display structure.
+
+Start the ball rolling by adding adafruit18, adafruit18_green and
+sainsmart18 displays.

+V4L2_PIX_FMT_BGR32 is deprecated as it is ambiguous over where

+
+Swap to the newer V4L2_PIX_FMT_BGRX32 format.

+Subject: [PATCH 200/697] staging: vc04_services: Add new vc-sm-cma driver
+
+Add Broadcom VideoCore Shared Memory support.
+
+This new driver allows contiguous memory blocks to be imported
+into the VideoCore VPU memory map, and manages the lifetime of
+those objects, only releasing the source dmabuf once the VPU has
+confirmed it has finished with it.

+
+staging: vcsm-cma: Fix memory leak from not detaching dmabuf
+
+When importing there was a missing call to detach the buffer,
+so each import leaked the sg table entry.
+
+Actually the release process for both locally allocated and
+imported buffers is identical, so fix them to both use the same
+function.

+staging/vc-sm-cma: Avoid log spamming on Pi0/1 over cache alias.
+
+Pi 0/1 use the 0x80000000 cache alias as the ARM also sees the world
+through the VPU L2 cache.
+vc-sm-cma was trying to ensure it was in an uncached alias (0xc), and
+complaining on every allocation if it weren't. Reduce this logging.

+vc-sm-cma: Restore correct cache maintainance operations
+
+We have been using the more expensive flush operations rather than
+invalidate and clean since kernel rpi-5.9.y
+
+These are exposed with:
+52f1453513ba95084ab811a030032fe605b0cbe2 Re-expose some dmi APIs for use in VCSM
+
+But I believe that commit was dropped when (non-cma) vc-sm was dropped,

+
+Commit d3292daee319 ("dma-buf: Make locking consistent in dma_buf_detach()")
+added checking that the same dmabuf for which dma_buf_attach
+was called is passed into dma_buf_detach, which flagged up
+that vcsm-cma was passing in the wrong dmabuf.
+
+Correct this so that we don't get the WARN on every dma_buf

++ *
++ * Based on vmcs_sm driver from Broadcom Corporation for some API,

++ *
++ *
++ * This driver has 3 main uses:

++ *    VPU.
++ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
++ * 3) Allocating buffers for use by the VPU.
++ *
++ * In the first and second cases the native handle is a dmabuf. Releasing the
++ * resource inherently comes from releasing the dmabuf, and this will trigger
++ * unmapping on the VPU. The underlying allocation and our buffer structure are
++ * retained until the VPU has confirmed that it has finished with it.
++ *
++ * For the VPU allocations the VPU is responsible for triggering the release,
++ * and therefore the released message decrements the dma_buf refcount (with the
++ * VPU mapping having already been marked as released).

+Subject: [PATCH 204/697] staging: vc04_services: Add a V4L2 M2M codec driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds a V4L2 memory to memory device that wraps the MMAL
+video decode and video_encode components for H264 and MJPEG encode
+and decode, MPEG4, H263, and VP8 decode (and MPEG2 decode
+if the appropriate licence has been purchased).
+
+This patch squashes all the work done in developing the driver
+on the Raspberry Pi rpi-5.4.y kernel branch.
+Thanks to Kieran Bingham, Aman Gupta, Chen-Yu Tsai, and
+Marek Behún for their contributions. Please refer to the
+rpi-5.4.y branch for the full history.

+
+staging: bcm2835-codec: Allow decode res changed before STREAMON(CAPTURE)
+
+The V4L2 stateful video decoder API requires that you can STREAMON
+on only the OUTPUT queue, feed in buffers, and wait for the
+SOURCE_CHANGE event.
+This requires that we enable the MMAL output port at the same time
+as the input port, because the output port is the one that creates
+the SOURCE_CHANGED event.

+
+staging/bcm2835-codec: Do not send buffers to the VPU unless streaming
+
+With video decode we now enable both input and output ports on

+earlier than desired if they are queued befoer STREAMON.
+
+Check that the queue is streaming before sending buffers to the VPU.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: bcm2835-codec: Format changed should trigger drain
+
+When a format changed event occurs, the spec says that it
+triggers an implicit drain, and that needs to be signalled
+via -EPIPE.
+
+For BCM2835, the format changed event happens at the point
+the format change occurs, so no further buffers exist from
+before the resolution changed point. We therefore signal the
+last buffer immediately.
+We don't have a V4L2 available to us at this point, so set
+the videobuf2 queue last_buffer_dequeued flag directly.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: bcm2835-codec: Signal the firmware to stop on all changes
+
+The firmware defaults to not stopping video decode if only the
+pixel aspect ratio or colourspace change. V4L2 requires us
+to stop decoding on any change, therefore tell the firmware
+of the desire for this alternate behaviour.

+
+staging: bcm2835-codec: Queue flushed buffers instead of completing

+When a buffer is returned on a port that is disabled, return it

+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging: bcm2835_codec: Correct flushing code for refcounting
+
+Completions don't reference count, so setting the completion
+on the first buffer returned and then not reinitialising it
+means that the flush function doesn't behave as intended.

+Signal the completion when the last buffer is returned.

+
+staging/bcm2835-codec: bytesperline for YUV420/YVU420 needs to be 64
+
+Matching https://github.com/raspberrypi/linux/pull/4419, the ISP
+block (which is also used on the input of the encoder, and output
+of the decoder) needs the base address of all planes to be aligned
+to multiples of 32. This includes the chroma planes of YUV420 and
+YVU420.
+If the height is only a multiple of 2 (not 4), then you get an odd
+number of lines in the second plane, which means the 3rd plane
+starts at a multiple of bytesperline/2.
+
+Set the minimum bytesperline alignment to 64 for those formats
+so that the plane alignment is always right.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+staging/bcm2835-codec: Allow a different stride alignment per role
+
+Deinterlace and decode aren't affected in the same way as encode
+and ISP by the alignment requirement on 3 plane YUV420.
+Decode would be affected, but it always aligns the height up to
+a macroblock, and uses the selection API to reflect that.

+staging: vc04_services: codec: Add support for V4L2_PIX_FMT_RGBA32 format

+
+bcm2835-codec: Return empty buffers to the VPU instead of queueing to vbuf2
+
+The encoder can skip frames totally should rate control overshoot
+the target bitrate too far. In this situation it generates an
+output buffer of length 0.
+V4L2 treats a buffer of length 0 as an end of stream flag, which is
+not appropriate in this case, therefore we can not return that buffer
+to the client.
+
+The driver was returning the buffer to videobuf2 in the QUEUED state,
+however that buffer was then not dequeued again, so the number of
+buffers was reduced each time this happened. In the pathological
+case of using GStreamer's videotestsrc in mode 1 for noise, this happens
+sufficiently frequently to totally stall the pipeline.
+
+If the port is still enabled then return the buffer straight back to
+the VPU rather than to videobuf2.

+old value was encoded in the bitstream.
+
+Update the port status when the framerate is set.

+staging: vc04_services: bcm2835-codec: Drop include Makefile directive
+
+Drop the include directive. They can break the build, when one only
+wants to build a subdirectory. Replace with "../" for the includes in
+the bcm2835-v4l2-codec instead.
+
+The fix is equivalent to the four patches between 29d49a76c5b2

+directive")...2529ca211402 ("staging: vc04_services: interface: Drop

+staging: bcm2835-codec: Disable HEADER_ON_OPEN for video encode
+
+Video encode can defer generating the header until the first
+frame is presented, which allows it to take the colourspace
+information from the frame rather than just the format.
+
+Enable that for the V4L2 driver now that the firmware populates
+all the parameters.

+vc04_services: codec: Allocate the max number of buffers on the VPU
+
+The VPU's API can't match the use of VIDIOC_CREATE_BUFS to add buffers
+to the internal pool whilst a port is enabled, therefore allocate
+the maximum number of buffers possible in V4L2 to avoid the issue.
+As these are only buffer headers, the overhead is relatively small.

+Subject: [PATCH 206/697] staging: vc04_services: ISP: Add a more complex ISP
+ processing component
+
+Driver for the BCM2835 ISP hardware block.  This driver uses the MMAL
+component to program the ISP hardware through the VC firmware.
+
+The ISP component can produce two video stream outputs, and Bayer
+image statistics. This can't be encompassed in a simple V4L2
+M2M device, so create a new device that registers 4 video nodes.
+
+This patch squashes all the development patches from the earlier
+rpi-5.4.y branch into one
+

+
+Now that the firmware supports the unpacked (16bpp) variants
+of the MIPI raw formats, add the mappings.

+
+Add the accompanying MMAL configuration structure definitions as well.

+
+bcm2835-isp: Allow formats with different colour spaces.
+
+Each supported format now includes a mask showing the allowed colour
+spaces, as well as a default colour space for when one was not
+specified.
+
+Additionally we translate the colour space to mmal format and pass it
+over to the VideoCore.

+staging/bcm2835-isp: Fix compiler warning

+
+staging: vc04_services: isp: Set the YUV420/YVU420 format stride to 64 bytes
+
+The bcm2835 ISP requires the base address of all input/output planes to have 32
+byte alignment. Using a Y stride of 32 bytes would not guarantee that the V
+plane would fulfil this, e.g. a height of 650 lines would mean the V plane
+buffer is not 32 byte aligned for YUV420 formats.
+
+Having a Y stride of 64 bytes would ensure both U and V planes have a 32 byte
+alignment, as the luma height will always be an even number of lines.

+Subject: [PATCH 207/697] gpio: Add gpio-fsm driver
+
+The gpio-fsm driver implements simple state machines that allow GPIOs
+to be controlled in response to inputs from other GPIOs - real and
+soft/virtual - and time delays. It can:
++ create dummy GPIOs for drivers that demand them,
++ drive multiple GPIOs from a single input, with optional delays,
++ add a debounce circuit to an input,
++ drive pattern sequences onto LEDs
+etc.

+gpio-fsm: Fix a build warning
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+gpio-fsm: Rename 'num-soft-gpios' to avoid warning
+
+As of 5.10, the Device Tree parser warns about properties that look
+like references to "suppliers" of various services. "num-soft-gpios"
+resembles a declaration of a GPIO called "num-soft", causing the value
+to be interpreted as a phandle, the owner of which is checked for a
+"#gpio-cells" property.
+
+To avoid this warning, rename the gpio-fsm property to "num-swgpios".

+
+gpio-fsm: Show state info in /sys/class/gpio-fsm
+
+Add gpio-fsm sysfs entries under /sys/class/gpio-fsm. For each state
+machine show the current state, which state (if any) will be entered
+after a delay, and the current value of that delay.
+

+
+gpio-fsm: Fix shutdown timeout handling
+
+The driver is intended to jump directly to a shutdown state in the
+event of a timeout during shutdown, but the sense of the test was
+inverted.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+gpio-fsm: Clamp the delay time to zero
+
+The sysfs delay_ms value is calculated live, and it is possible for
+the time left to appear to be negative briefly if the timer handling
+hasn't completed. Ensure the displayed value never goes below zero,

+gpio-fsm: Sort functions into a more logical order
+
+Move some functions into a more logical ordering. This change causes
+no functional change and is essentially cosmetic.

+
+gpio_fsm: Rework the atomic-vs-non-atomic split
+
+Partition the code to separate atomic and non-atomic methods so that
+none of them have to handle both cases. The result avoids using deferred
+work unless necessary, and should be easier to understand.

+Subject: [PATCH 209/697] firmware: raspberrypi: Add support for tryonce reboot
+ flag
+
+Define a new mailbox (SET_REBOOT_FLAGS) which may be used to
+pass optional flags to the Raspberry Pi firmware that changes
+the behaviour of the bootloader and firmware during a reboot.
+
+Currently this just defines the 'tryboot' flag which causes
+the firmware to load tryboot.txt instead config.txt. This
+alternate configuration file can be used to specify the
+path of an alternate firmware and kernels allowing a fallback
+mechanism to be implemented for OS upgrades.

+From 3ce102ab49d08db6a961e38d9794a77db85ef3f0 Mon Sep 17 00:00:00 2001
+From: Dave Stevenson <dave.stevenson@raspberrypi.com>
+Date: Fri, 6 Nov 2020 18:45:10 +0000
+Subject: [PATCH 210/697] Input: edt-ft5x06: Poll the device if no interrupt is
+ configured.
+
+Not all systems have the interrupt line wired up, so switch to
+polling the touchscreen off a timer if no interrupt line is
+configured.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: edt-ft5x06: Handle unreliable TOUCH_UP events
+
+The ft5x06 is unreliable in sending touch up events, so some
+touch IDs can become stuck in the detected state.
+
+Ensure that IDs that are unreported by the controller are
+released.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: edt-ft5x06: Only look at the number of points reported
+
+Register 0x02 in the FT5x06 is TD_STATUS containing the number
+of valid touch points being reported.
+
+Iterate over that number of points rather than all that are
+supported on the device.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: edt-ft5x06: Only read data for number of points reported
+
+Rather than always reading the maximum number of points supported
+by the chip (which may be as high as 10), read the number of
+active points first, and read data for just those.
+In most cases this will result in less data on the I2C bus,
+with only the maximum touch points taking more due to a second
+read that has to configure the start address.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: edt-ft5x06: Fix patch reading only the number of points reported
+
+Fix bad conflict resolution from upstream updates. Need to read
+from tsdata->tdata_offset bytes, not from tsdata->offset.
+Also fix logging of i2c read errors to cover both transactions.
+
+Fixes: 7216fcfe2e5f ("input: edt-ft5x06: Only read data for number of points reported")
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+Input: edt-ft54x6: Clean up timer and workqueue on remove
+
+If no interrupt is defined then a timer and workqueue are used
+to poll the controller.
+On remove these were not being cleaned up correctly.
+
+Fixes: ca61fdaba79f "Input: edt-ft5x06: Poll the device if no interrupt is
+configured."
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: touchscreen: edt-ft5x06: Suppress bogus data on startup
+
+When polled without the use of IRQ, FT5x06 registers may return
+undefined initial data, causing unwanted touches or event spamming.
+A simple way to filter this out is to suppress touches until the
+TD_STATUS register changes for the first time.
+
+Increase the delay before first polling to 300ms, to avoid
+transient I2C read flakiness that seems to occur after reset.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+input: edt-ft5x06: Include I2C details in names for the devices
+
+libinput uses the input device name alone. If you have two
+identical input devices, then there is no way to differentiate
+between them, and in the case of touchscreens that means no
+way to associate them with the appropriate display device.
+
+Add the I2C bus and address to the start of the input device
+name so that the name is always unique within the system.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: edt-ft5x06: Correct prefix length in snprintf
+
+snprintf takes the length of the array that we can print into,
+and has to fit the NULL terminator in there too.
+Printing the prefix is generally "12-3456 " which is 8 desired
+characters (the length of EDT_NAME_PREFIX_LEN) and the NULL.
+The space is therefore being truncated to fit the NULL in.
+
+Increase the length snprintf is allowed to use.

+Commit 65e08c465020d4c5b51afb452efc2246d80fd66f failed to clear the
+clock state when the device stopped streaming. Fix this, as it might
+again cause the same problems when doing an unprepare.

+Subject: [PATCH 215/697] PCI: brcmstb: Add BCM2712 support
+
+PCI: brcmstb: Add DT property to control L1SS
+
+The BRCM PCIe block has controls to enable control of the CLKREQ#
+signal by the L1SS, and to gate the refclk with the CLKREQ# input.
+These controls are mutually exclusive - the upstream code sets the
+latter, but some use cases require the former.
+
+Add a Device Tree property - brcm,enable-l1ss - to switch to the
+L1SS configuration.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+PCI: brcmstb: Advertise MSI-X support
+
+Although the BRCMSTB PCIe interface doesn't technically support the
+MSI-X spec, in practise it seems to work provided no more than 32
+MSI-Xs are required. Add the required flag to the driver to allow
+experimentation with devices that demand MSI-X support.

+
+pcie-brcmstb: Suppress read error responses
+
+If the link is down or the EP fails to return a read completion, the
+RC's default behaviour is to return an AXI error. This causes fatal
+exceptions on A76, so it's better to respond with all 1s instead.
+
+pcie-brcmstb: increase UBUS timeout to cater for link retrain events
+
+pcie-brcmstb: Handle additional inbound regions
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pcie-brcmstb: Add support for external MSI controller
+
+pcie-brcmstb: add a reasonable default traffic class to priority map
+
+BCM2712 supports multiple traffic classes (TCs) with independent
+maximally sized transfer queues for each TC. Traffic classes have no
+transaction ordering requirements between them, which facilitates
+out-of-order completions and arbitration between posted writes for
+data streams that have no dependence on each other.
+
+In addition to the above benefits of splitting endpoint traffic into
+individual queues, priorities can be assigned to traffic classes by
+a heuristic or deterministic mechanism. The heuristic elevates AXI
+QOS priority in accordance with the number of pending transfers in
+each TC's queue, but for true priority signalling a forwarding
+mechanism using vendor-defined messages is implemented.
+
+Receipt of a 3 DWORD VDM assigns a priority tag to a TC on-the-fly,
+and this tag corresponds to a configurable AXI QOS value.
+
+As a simple baseline, assign a linear map of AXI QOS to each tag.
+
+pcie: brcmstb: set up the VDM forwarding interface when setting up QoS
+
+pcie-brcmstb: clean up debug messages
+
+pcie-brcmstb: fix BCM2712A0 PHY PM errata
+
+The power management clock is 54MHz not 50MHz, so adjust the PM clock period
+to suit. Powering off the PHY PLL in L1.2 is unsafe, so force it on.
+
+pcie-brcmstb: set CLKREQ functionality according to link partner support
+
+The RC supports either L1 with clock PM or L1 sub-state control, not both
+at the same time. Examine the link partner's capabilities to determine
+which is the most suitable scheme to use.
+
+pcie: brcmstb: don't reset block bridges in suspend or removal cases
+
+BCM2712 has a single rescal block for all three root complexes, and
+holding PCIE1's bridge in reset will hang the chip if a different
+RC wants to access any of the rescal registers.
+
+pcie: brcmstb: guard 2712-specific setup with a RC type check
+
+BCM2711 doesn't implement the UBUS control registers.
+
+pcie: brcmstb: On 2712 keeping the PLL powered in L1.x is not required
+
+A separate misconfiguration when enabling SSC (the MDIO registers no
+longer do the same thing on BCM2712) had the side-effect of breaking
+PLL powerdown and resume sequencing.
+
+Allow entry into a true L1.2 state where analogue is depowered.

+
+bcm2712: pcie: adjust PHY PLL setup to use a 54MHz input refclk
+
+Use canned MDIO writes from Broadcom that switch the ref_clk output
+pair to run from the internal fractional PLL, and set the internal PLL
+to expect a 54MHz input reference clock.
+
+Gen3 operation is not guaranteed to be stable in this setup, so default
+to gen2.
+
+This only works if the LCPLL is bypassed (requires latest bootloader).
+
+pcie: brcmstb: add missing register writes
+
+drivers: pcie: brcmstb: cater for BCM2712C0 bug dropping QoS on the floor
+
+The AXI QoS value extracted from the request fifo ends up as zero forever.
+Disabling this means that "panic" signalling doesn't do anything useful,
+but static priorites do work.
+
+Also align the selected TC:QoS map with RP1's expectations of service.

+Use the range 8-11 which puts the highest below HVS but leaves space

+
+drivers: pcie: brcmstb: optionally enable QoS features by DT for BCM2712
+
+It's a bad idea to universally enable "realtime" priorities for TCs
+across all the RC instances on the chip. Endpoints other than RP1 may
+make use of these, so you don't want e.g. NVMe descriptor fetches getting
+higher priority than your remote display.
+
+Add two optional DT properties controlling the behaviour - FIFO-based
+backpressure QoS or "message-based". Message-based signalling is
+fundamentally broken due to a chip bug, so it collapses into a set of
+static assignments that RP1 needs.
+
+The default if neither property is specified is to assign everything a
+QoS of 0.

+PCI: brcmstb: Change RCB_{MPS,64B}_MODE bits
+
+Upstream commit [1] unconditionally sets the RCB_MPS and RCB_64B bits
+that govern where packets are split. We think this is potentially
+harmful, particularly on CM4 and Pi 5 where potentially any PCIe devices
+could be attached.
+
+Make RCB_MPS conditional on a DT property and never set RCB_64B.

+PCI: brcmstb: don't set bridge timeouts on BCM2712
+
+BCM2712 has a slightly different architecture to most other STB chips.
+
+Timeout values are internal to the core and are set in PCIE_MISC not
+PCIE_RGR1.

+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+PCI: brcmstb: Enable CRS software visibility after linkup
+
+It appears that bits in the Root Control Register are reset with
+perst_n, which means the PCI layer's call to enable CRS prior to
+adding/scanning the bus has no effect. Open-code the enable in
+brcm_pcie_start_link as a workaround.
+
+Without CRS visibility, configuration reads issued by the CPU don't
+retire if the endpoint returns a CRS response - the RC will poll until a
+(large) timeout is reached. This means the core can stall for a long
+time during boot.

+PCI: brcmstb: Set new flags to avoid QOS "holes" on BCM2712D0
+
+Set some flags present (and recommended) in 2712D0, but missing
+(and harmless) in 2712C1. In particular, EN_QOS_UPDATE_TIMING_FIX
+must be set to avoid spurious QOS=0 when the queue changes from
+empty to non-empty, to make D0 match the existing C1 behaviour.
+
+Not enabling "QOS forwarding", which still seems not to help.

+
+drivers: pcie-brcmstb: add best-effort workaround for QoS bug on bcm2712
+
+If a set of read requests are issued by an endpoint, they are streamed
+into a resynchronisation FIFO prior to exiting the RC. This FIFO has an
+edge case where it can drop QoS for a request to 0 if there's a single
+outstanding read request in the FIFO, and another is pushed when the
+FIFO is popped. Requests with a QoS of 0 can take hundreds of
+microseconds to complete.
+
+By adding an experimentally-determined amount of backpressure on the pop
+side, the critical level transition can largely be avoided.

++	 * viewport -- we can map the outbound memory in or after 3GB and even
++	 * though the viewport will overlap the outbound memory the controller
++	 * will know to send outbound memory downstream and everything else
++	 * upstream.
++	 *
++	 * For example:
++	 *
++	 * - The best-case scenario, memory up to 3GB, is to place the inbound
++	 *   region in the first 4GB of pcie-space, as some legacy devices can
++	 *   only address 32bits. We would also like to put the MSI under 4GB
++	 *   as well, since some devices require a 32bit MSI target address.
++	 *
++	 * - If the system memory is 4GB or larger we cannot start the inbound
++	 *   region at location 0 (since we have to allow some space for
++	 *   outbound memory @ 3GB). So instead it will  start at the 1x

+Subject: [PATCH 218/697] spi: bcm2835: Workaround/fix for zero-length
+ transfers
+
+A relatively recent commit ([1]) contained optimisation for the PIO
+SPI FIFO-filling functions. The commit message includes the phrase
+"[t]he blind and counted loops are always called with nonzero count".
+This is technically true, but it is still possible for count to become
+zero before the loop is entered - if tfr->len is zero. Moving the loop
+exit condition to the end of the loop saves a few cycles, but results
+in a near-infinite loop should the revised count be zero on entry.
+
+Strangely, zero-lengthed transfers aren't filtered by the SPI framework
+and, even more strangely, the Python3 spidev library is triggering them
+for no obvious reason.
+
+Avoid the problem completely by bailing out of the main transfer
+function early if trf->len is zero, although there may be a case for
+moving the mitigation into the framework.
+
+See: https://github.com/raspberrypi/linux/issues/4100

+Subject: [PATCH 219/697] media: bcm2835-unicam: Fix bug in buffer swapping
+ logic
+
+If multiple sets of interrupts occur simultaneously, it may be unsafe
+to swap buffers, as the hardware may already be re-using the current
+buffers. In such cases, avoid swapping buffers, and wait for the next
+opportunity at the Frame End interrupt to signal completion.
+
+Additionally, check the packet compare status when watching for frame
+end for buffers swaps, as this could also signify a frame end event.

+Subject: [PATCH 220/697] Assign crypto aliases to different AES implementation
+ modules
+
+The kernel modules aes-neon-blk and aes-neon-bs perform poorly, at least on
+Cortex-A72 without crypto extensions. In fact, aes-arm64 outperforms them
+on benchmarks, despite it being a simpler implementation (only accelerating
+the single-block AES cipher).
+
+For modes of operation where multiple cipher blocks can be processed in
+parallel, aes-neon-bs outperforms aes-neon-blk by around 60-70% and aes-arm64
+is another 10-20% faster still. But the difference is even more marked with
+modes of operation with dependencies between neighbouring blocks, such as
+CBC encryption, which defeat parallelism: in these cases, aes-arm64 is
+typically around 250% faster than either aes-neon-blk or aes-neon-bs.
+
+The key trade-off with aes-arm64 is that the look-up tables are situated in
+RAM. This leaves them potentially open to cache timing attacks. The two other
+modules, by contrast, load the look-up tables into NEON registers and so are
+able to perform in constant time.
+
+This patch aims to load aes-arm64 more often.
+
+If none of the currently-loaded crypto modules implement a given algorithm,
+a new one is typically selected for loading using a platform-neutral alias
+describing the required algorithm. To enable users to still
+load aes-neon-blk or aes-neon-bs if they really want them, while still
+ensuring that aes-arm64 is usually selected, remove the aliases from
+aes-neonbs-glue.c and aes-glue.c and apply them to aes-cipher-glue.c, but
+still build the two NEON modules.
+
+Since aes-glue.c can also be used to build aes-ce-blk, leave them enabled
+if USE_V8_CRYPTO_EXTENSIONS is defined, to ensure they are selected if we
+in future use a CPU which has the crypto extensions enabled.
+
+Note that the algorithm priority specifiers are unchanged, so if
+aes-neon-bs is loaded at the same time as aes-arm64, the former will be
+used in preference. However, aes-neon-blk and aes-arm64 have tied priority,
+so whichever module was loaded first will be used (assuming aes-neon-bs is
+not loaded).

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The vidioc_enum_input() v4l2 ioctl is capable of returning
+sensor/input status as well. This is used in current
+GStreamer HEAD for signal detection [1].
+
+bcm2835-unicam does handle this syscall, but it didn't ask
+the subdevice driver about the input status. The input then
+appeared as always present.
+
+This commit adds the necessary query. There is a precedent for
+this - the R-Car VIN V4L2 driver does a similar call [2].

+ I2C actions with delay.
+
+We now have the hardware I2C controller pinmuxed to the drive the
+display I2C, but this controller does not support clock stretching.
+The Atmel micro-controller in the panel requires clock stretching
+to allow it to prepare any data to be read.
+
+Split the rpi_touchscreen_i2c_read into two independent transactions with
+a delay between them for the Atmel to prepare the data.
+

+
+drm/panel/raspberrypi-ts: Insert delay before polling for startup state
+
+In switching to the hardware I2C controller there is an issue
+where we seem to not get back the correct state from the Pi
+touchscreen.
+Insert a delay before polling to avoid this condition.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel/raspberrypi-touchscreen: Handle I2C errors.
+
+rpi_touchscreen_i2c_read returns any errors from i2c_transfer,
+or the 8 bit received value.
+Check for error values before trying to process the data as
+valid.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel/raspberrypi-touchscreen: Insert more delays.
+
+This avoids failures in cases where the panel is enabled
+or re-probed very soon after being disabled or probed.
+These can occur because the Atmel device can mis-behave
+over I2C for a few ms after any write to the POWERON register.

+Subject: [PATCH 232/697] drm/panel-simple: Add a timing for the Raspberry Pi
+ 7" panel
+
+The Raspberry Pi 7" 800x480 panel uses a Toshiba TC358762 DSI
+to DPI bridge chip, so there is a requirement for the timings
+to be specified for the end panel. Add such a definition.

+
+drm/panel-simple: Populate bpc when using panel-dpi
+
+panel-dpi doesn't know the bit depth, so in the same way that
+DPI is guessed for the connector type, guess that it'll be 8bpc.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel-simple: Allow the bus format to be read from DT for panel-dpi
+
+The "panel-dpi" compatible string configures panel from device tree,
+but it doesn't provide any way of configuring the bus format (colour
+representation), nor does it populate it.
+
+Add a DT parameter "bus-format" that allows the MEDIA_BUS_FMT_xxx value
+to be specified from device tree.

+drm/panel: simple: Alter the timing for the Pi 7" DSI display
+
+vc4 has always fixed up the timing, so the values defined have
+never actually appeared on the wire.
+The display appears to want a slightly longer HFP, so extend
+the timings and recompute the clock to give the same frame rate.

+
+drm/panel: add panel-dsi
+
+Equivalent to panel-dpi for configuring a simple DSI panel with
+device tree side timings and bus settings.
+Motiviation is the same as for panel-dpi of wanting to support
+new simple panels without needing to patch the kernel.

+
+drm/panel-simple: Remove custom handling of orientation
+
+The framework now handles reading orientation from DT, therefore
+remove the custom get_orientation hook from panel-simple.

+
+drm/panel-simple: Fix 7inch panel mode for misalignment
+
+The 7inch panel is one line off the screen both horizontally
+and vertically.
+
+Alter the panel mode to correct this.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel-simple: Increase pixel clock on Pi 7inch panel
+
+The Toshiba bridge is very fussy and doesn't like the CM3
+output when being told to produce a 27.777MHz pixel clock, which
+is an almost perfect match to the DSI link integer divider.
+
+Increasing to 30MHz will switch the DSI link from 333MHz to 400MHz
+and makes the bridge happy with the same video timing as works
+on Pi4.
+(Pi4 will be using a link frequency of 375MHz due to a 3GHz
+parent PLL).

+Subject: [PATCH 233/697] drm/panel: jdi-lt070me05000: Use
+ gpiod_set_value_cansleep
+
+There is no reason why the control GPIOs for the panel can not
+be connected to I2C or similar GPIO interfaces that may need to
+sleep, therefore switch from gpiod_set_value to
+gpiod_set_value_cansleep calls to configure them.
+Without that you get complaints from gpiolib every time the state
+is changed.

+drm: panel: jdi-lt070me05000: Add prepare_upstream_first flag
+
+The panel driver wants to send DCS commands from the prepare
+hook, therefore the DSI host wants to be pre_enabled first.
+Set the flag to achieve this.

+drm/panel: ilitek-ili9881c: Clean up on mipi_dsi_attach failure
+
+mipi_dsi_attach is allowed to fail, and currently the probe
+code doesn't clean up (mainly drm_panel_remove) if this happens.
+
+Add cleanup code on failure.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel: panel-ilitek9881c: Add prepare_upstream_first flag
+
+The panel sends MIPI DCS commands during prepare and is expecting
+the bus to remain in LP-11 state in-between.
+
+Set the prepare_upstream_first flag so that the upstream DSI host
+is prepared / pre_enabled first, and therefore the bus is in a
+defined state.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/panel: panel-ilitek9881c: Use cansleep methods
+
+Use cansleep version of gpiod_set_value so external IO drivers (like
+via I2C) can be used.
+
+Signed-off-by: Mark Williams <mwp@mwp.id.au>
+
+drm/panel: panel-ilitek9881c: Crystalfontz support

+drm/panel: ilitek-ili9881c: Allow configuration of the number of lanes
+
+Not all panels use all 4 data lanes, so allow configuration based
+on the compatible string.

+ panels
+
+This new panel uses the ILI9881C IC but needs an alternate

+Subject: [PATCH 236/697] drm/panel: Add panel driver for TDO Y17B based panels
+
+The Top DisplayOptoelectronics (TDO) T17B driver chip is used
+in the TL040HDS20CT panel (found in the Pimoroni HyperPixel4
+Square display) and potentially other displays.
+The driver chip supports SPI for  configuration and DPI
+video data.

+Subject: [PATCH 237/697] drm/panel: Add panel driver for Waveshare DSI
+ touchscreens
+
+Waveshare sell a range of DSI panels of varying sizes, all
+using a common MCU to control the panel and backlight.
+
+Add a panel driver that supports these panels.

+drm/panel: waveshare: Fix up timings for 10.1" panel
+
+The 10.1" panel doesn't work with the timings defined. vc4
+will always have been fixing up the timing due to the limited
+integer divider, so compute the fixed up mode and use it
+directly.

+Subject: [PATCH 239/697] dt-bindings: display: simple: add Geekworm MZP280
+ Panel
+
+The Geekworm MZP280 panel is a 480x640 (portrait) panel with a
+capacitive touch interface and a 40 pin header meant to interface
+directly with the Raspberry Pi. The screen is 2.8 inches diagonally,
+and there appear to be at least 4 distinct versions all with the same
+panel timings.
+
+Timings were derived from drivers posted on the github located here:
+https://github.com/tianyoujian/MZDPI/tree/master/vga
+
+Additional details about this panel family can be found here:
+https://wiki.geekworm.com/2.8_inch_Touch_Screen_for_Pi_zero

+Subject: [PATCH 246/697] staging: mmal-vchiq: Reset buffers_with_vpu on
+ port_enable
+
+Should we go through the timeout failure case with port_disable
+not returning all buffers for whatever reason, the
+buffers_with_vpu counter gets left at a non-zero value, which
+will cause reference counting issues should the instance be
+reused.
+
+Reset the count when the port is enabled again, but before
+any buffers have been sent to the VPU.

+Subject: [PATCH 247/697] hwmon: (pwm-fan) Add fan speed register support
+
+Some platforms include a fan-speed register that reports RPM directly
+as an alternative to counting interrupts from the fan tachometer input.
+Add support for reading a register at a given offset (rpm-offset) within
+a block declared in another node (rpm-regmap). This indirection allows
+the usual address mapping to be performed, and for address sharing with
+another driver.

+The driver was making big assumptions about the source device
+using pad 0 and 1, which doesn't follow for more complex
+devices where Unicam's source device may be a sink device for
+something else.
+
+Read the pad numbers through media controller, and reference
+them appropriately.

+Subject: [PATCH 251/697] media/bcm2835-unicam: Add support for configuration
+ via MC API
+
+Adds Media Controller API support for more complex pipelines.
+libcamera is about to switch to using this mechanism for configuring
+sensors.
+
+This can be enabled by either a module parameter, or device tree.
+
+Various functions have been moved to group video-centric and
+mc-centric functions together.
+
+Based on a similar conversion done to ti-vpe.

+
+media: bcm2835-unicam: Fixup for 5.18 and new get_mbus_config struct
+
+The number of active CSI2 data lanes has moved within the struct
+v4l2_mbus_config used by the get_mbus_config API call.
+Update the driver to match the changes in mainline.

+Subject: [PATCH 254/697] brcmfmac: Don't promote INFO logging to ERR
+
+An unwanted side effect of enabling the BRCMDBG config setting is
+redefining brcmf_info to be brcmf_err. This can be alarming to users
+and makes it harder to spot real errors, so don't do it.

+
+The I2C to the Atmel is very fussy, and locks up easily on
+Pi0-3 particularly on reads.
+
+The LCD power status is controlled solely by this driver, so
+rather than reading it back from the Atmel, use the cached
+status last set.

+
+regulator/rpi-panel: Remove the ID read
+
+Reading from the Atmel has always been troublesome due to
+clock stretching, and the driver does nothing with it anyway.
+
+Remove the read and assume that if the overlay has been
+configured (most likely through the firmware autodetection)
+that the hardware is present.

+Subject: [PATCH 266/697] power: rpi-poe: Add option of being created by MFD or
+ FW
+
+The firmware can only use I2C0 if the kernel isn't, therefore
+with libcamera and DRM using it the PoE HAT fan control needs
+to move to the kernel.
+
+Add the option for the driver to be created by the PoE HAT core
+MFD driver, and use the I2C regmap that provides to control fan
+functions.

+Subject: [PATCH 267/697] drivers: bcm2835_unicam: Disable trigger mode
+ operation
+
+On a Pi3 B/B+ platform the imx219 sensor frequently generates a single corrupt
+frame when the sensor first starts. This can either be a missing line, or
+invalid samples within the line. This only occurrs using the Unicam kernel
+driver.
+
+Disabling trigger mode elimiates this corruption. Since trigger mode is a
+legacy feature copied from the firmware driver and not expected to be needed,
+remove it. Tested on the Raspberry Pi cameras and shows no ill effects.

+Subject: [PATCH 269/697] i2c: bcm2835: Make clock-stretch timeout configurable
+
+The default clock-stretch timeout is 35 mS, which works well for
+SMBus, but there are some I2C devices which can stretch the clock even
+longer. Rather than trying to prescribe a safe default for everyone,
+allow the timeout to be configured.

+Subject: [PATCH 276/697] media: i2c: Add driver for AD5398 VCM lens driver
+
+Adds a driver for the Analog Devices AD5398 10 bit
+I2C DAC which is commonly used for driving VCM lens
+mechanisms.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+media: i2c: Rename ad5398 to ad5398_vcm
+
+There's already a regulator module called ad5398 that exposes
+this device through the regulator API. That is meaningless in
+the terms that it uses and how it maps to V4L2, so a new driver
+was added. However the module name collision wasn't noted, so
+rename it now.

+Subject: [PATCH 278/697] mm,page_alloc,cma: introduce a customisable threshold
+ for allocating pages in cma
+
+On some platforms the cma area can be half the entire system memory,
+meaning that allocations start happening in the cma area immediately.
+This leads to fragmentation and subsequent fatal cma_alloc failures.
+
+We introduce an "alloc_in_cma_threshold" parameter which requires that
+this many sixteenths of the free pages must be in cma before it will
+try to use them. By default this is set to 12, but the previous
+behaviour can be restored by setting it to 8 on startup.

+It is quite common for the devm_thermal_zone_of_sensor_register
+to need to defer, so avoid spamming the log by using
+dev_err_probe instead of dev_err.

+hwmon: emc2305: Add calls to initialise of cooling maps
+
+Commit 46ef9d4ed26b ("hwmon: emc2305: fixups for driver submitted to

+required to configure any cooling maps for the device, hence stopping it

+hwmon: emc2305: Change OF properties pwm-min & pwm-max to u8
+
+There is no DT binding for emc2305 as mainline are still
+discussing how to do a generic fan binding.
+The 5.15 driver was reading the "emc2305," properties
+"cooling-levels", "pwm-max", "pwm-min", and "pwm-channel" as u8.
+The overlay was writing them as u16 (;) so it was working.
+
+The 6.1 driver was reading as u32, which failed as there is
+insufficient data.
+
+As this is all downstream only, revert to u8 to match 5.15.

+Subject: [PATCH 289/697] media: i2c: Add driver of Arducam 64MP camera
+
+Add a driver for the Arducam 64MP camera sensor.
+Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
+currently only supports 2 lanes.
+
+The following Bayer modes are currently available:
+
+9152x6944 10-bit @ 2.7fps
+4624x3472 10-bit (binned) @ 10fps
+3840x2160 10-bit (cropped/binned) @ 20fps
+2312x1736 10-bit (binned) @ 30fps
+1920x1080 10-bit (cropped/binned) @ 60fps
+1280x720 10-bit (cropped/binned) @ 120fps

+media: i2c: arducam_64mp: Advertise embedded data node on media pad 1
+
+This commit updates the arducam_64mp driver to adverise support for
+embedded data streams.
+
+The arducam_64mp sensor subdevice overloads the media pad to differentiate
+between image stream (pad 0) and embedded data stream (pad 1) when
+performing the v4l2_subdev_pad_ops functions.

+
+media: i2c: arducam_64mp: Modify the line length of 1280x720 resolution
+
+Arducam 64MP has specific requirements for the line length, and if these
+conditions are not met, the camera will not function properly. Under the
+previous configuration, once a stream off operation is performed, the
+camera will not output any data, even if a stream on operation is
+performed. This prevents us from switching from 1280x720 to another
+resolution.

+snd_bcm2835: disable HDMI audio when vc4 is used (#3640)
+
+Things don't work too well when both the vc4 driver and the firmware
+driver are trying to control the same audio output:
+
+[  763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
+
+Hence, when the vc4 HDMI driver is used, let it control audio. This is done
+by introducing a new device tree property to the audio node, and
+extending the vc4-kms-v3d overlays to set it appropriately.
+
+Signed-off-by: Hristo Venev <hristo@venev.name>
+
+staging: bcm2835-audio: Add disable-headphones flag
+
+Add a property to allow the headphone output to be disabled. Use an
+integer property rather than a boolean so that an overlay can clear it.

+
+staging: bcm2835-audio: Find compatible firmware node
+
+Commit "ARM: dts: Adopt the upstream snd_bcm2835 handling" removed the
+audio section from the DT and the driver can no longer access the
+referenced firmware node 'brcm,firmware'. Fix that by searching for a
+compatible firmware node instead, similar to drivers/gpu/drm/vc4.

+staging: bcm2835-audio: Fix unused enable_hdmi module parameter
+
+The commit "Add HDMI1 facility to the driver." made the enable_hdmi module
+parameter unused. Fix that by making it a global switch for all available
+HDMI audio outputs.

+staging: bcm2835-audio: Fix unused enable_headphones module parameter
+
+Since commit "staging: bcm2835-audio: Add disable-headphones flag" the
+enabling/disabling of the headphones output is solely determined by the
+presence of the DT property 'brcm,disable-headphones' and the
+enable_headphones module parameter is unused. Fix that by making it a
+global switch.

+ condtion
+
+If we get a simultaneous FS + FE interrupt for the same frame, it cannot be
+marked as completed and returned to userland as the framebuffer will be refilled
+by Unicam on the next sensor frame. Additionally, the timestamp will be set to 0
+as the FS interrupt handling code will not have run yet.
+
+To avoid these problems, the frame is considered dropped in the FE handler,
+and will be returned to userland on the subsequent sensor frame.

+ overrun
+
+The Unicam hardware has been observed to cause a buffer overrun when using the
+dummy buffer as a circular buffer. The conditions that cause the overrun are not
+fully known, but it seems to occur when the memory bus is heavily loaded.
+
+To avoid the overrun, program the hardware with a buffer size of 0 when using
+the dummy buffer. This will cause overrun into the allocated dummy buffer, but
+avoid out of bounds writes.

+ bidirectional VCM driver
+
+The DW9817 is effectively the same as DW9807 from a programming
+interface, however it drives +/-100mA instead of 0-100mA. This means
+that the power on ramp needs to take the lens from the midpoint, and
+power off return it there. It also changes the default position for

+Subject: [PATCH 302/697] media: dw9807-vcm: Add regulator support to the
+ driver
+
+Uses the regulator notifier framework so that the current
+focus position will be restored whenever any user of the
+regulator powers it up. This means that should the VCM
+and sensor share a common regulator then starting the sensor
+will automatically restore the default position. If they
+have independent regulators then it will behave be powered
+up when the VCM subdev is opened.

+
+The power up/down sequence is already ramped. Extend this to
+the first user movement as well, as this will generally avoid
+the "tick" noises due to rapid movements and overshooting.
+Subsequent movements are generally smaller and so don't cause
+issues.

+Subject: [PATCH 305/697] media/i2c: Add a driver for the Sony IMX708 image
+ sensor
+
+The imx708 is a 12MP MIPI sensor with a 16:9 aspect ratio, here using
+two CSI-2 lanes. It is a "quad Bayer" sensor with all 3 modes offering
+10-bit output:
+
+12MP: 4608x2592 up to 14.35fps (full FoV)
+1080p: 2304x1296 up to 56.02fps (full FoV)
+720p: 1536x864 up to 120.12fps (cropped)
+
+This imx708 sensor driver is based heavily on the imx477 driver and
+has been tested on the Raspberry Pi platform using libcamera.

+
+drivers: media: i2c: imx708: Fix WIDE_DYNAMIC_RANGE control with long exposure
+
+Setting V4L2_CID_WIDE_DYNAMIC_RANGE was causing the long exposure
+shift count to be reset, which is incorrect if the user has already
+changed the frame length to cause it to have a non-zero value.
+
+Because it only updates control ranges and doesn't set any registers,
+the control can also be applied when the sensor is not powered on.

+
+drivers: media: imx708: Increase usable link frequencies
+
+Add support for three different usable link frequencies (default 450Mhz,
+447Mhz, and 453MHz) for the IMX708 camera sensor. The choice of
+frequency is handled thorugh the "link-frequency" overlay parameter.

+drivers: media: imx708: Tidy-ups to address upstream review comments
+
+This commit addresses vaious tidy-ups requesed for upstreaming the
+IMX708 driver. Notably:
+
+- Remove #define IMX708_NUM_SUPPLIES and use ARRAY_SIZE() directly
+- Use dev_err_probe where possible in imx708_probe()
+- Fix error handling paths in imx708_probe()

+drivers: media: imx708: Adjust broken line correction parameter
+
+In full-resolution mode, the LPF_INTENSITY_EN and LPF_INTENSITY
+registers control Quad Bayer Re-mosaic broken line correction.
+Expose this as a module parameter "qbc_adjust": zero disables
+the correction and values in the range 2 to 5 set its strength.
+
+There is a trade-off between coloured and monochrome patterns.
+The previous fixed value 4 could produce ladder/spots artefacts
+in coloured textures. The new default value 2 may suit a wider
+range of scenes.

+Subject: [PATCH 306/697] media: bcm2835-unicam: Use mipi-csi2.h header for
+ data type values
+
+The MIPI CSI2 data type ID values are now defined in the
+mipi-csi2.h header, so use those defines instead of hard
+coding them in the driver.

+Subject: [PATCH 318/697] fbdev: Don't cancel deferred work if pagelist empty
+
+Since [1], the fbdev deferred IO framework is careful to cancel
+pending updates on close to prevent dirty pages being accessed after
+they may have been reused. However, this is not necessary in the case
+that the pagelist is empty, and drivers that don't make use of the
+pagelist may have wanted updates cancelled for no good reason.

+Subject: [PATCH 320/697] media: bcm2835-unicam: Start and stop media_pipeline
+ with same node
+
+media_pipeline_start and media_pipeline_stop now validate that
+the pipeline is being started and stopped with the same pipe
+and pad handles.
+When running with embedded metadata (eg imx477 and imx708), the
+start typically happens from the metadata pad, whilst stop is
+always from the image pad.
+
+Always pass the image pad to media_pipeline_start to ensure
+that the calls are balanced.

+Subject: [PATCH 321/697] input: goodix: Add option to poll instead of relying
+ on IRQ line
+
+The interrupt line from the touch controller is not necessarily
+connected to the SoC, so add the option to poll for touch info.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+input: goodix: Include I2C details in names for the devices
+
+libinput uses the input device name alone. If you have two
+identical input devices, then there is no way to differentiate
+between them, and in the case of touchscreens that means no
+way to associate them with the appropriate display device.
+
+Add the I2C bus and address to the start of the input device
+name so that the name is always unique within the system.

+Subject: [PATCH 322/697] serial: 8250: Add NOMSI bug for bcm2835aux
+
+The BCM2835 mini-UART has no modem status interrupt, causing all
+transmission to stop, never to use, if a speed change ever happens
+while the CTS signal is high.
+
+Add a simple polling mechanism in order to allow recovery in that
+situation.

+Subject: [PATCH 323/697] Bluetooth: hci_sync: Add fallback-bd-address prop
+
+The kernel Bluetooth framework understands that devices may not
+be programmed with valid Bluetooth addresses. It also has the ability
+to override a Bluetooth address with the value of the local-bd-address
+DT property, but it ignores the validity of the existing address when
+doing so.
+
+Add a new boolean property, fallback-bd-address, which indicates that
+the given local-bd-address property should only be used if the device
+does not already have a valid BDADDR.

+Subject: [PATCH 325/697] pinctrl: bcm2835: Workaround for edge IRQ loss
+
+It has been observed that edge events can be lost when GPIO edges occur
+close to each other. Investigation suggests this is due to a hardware
+bug, although no mechanism has been identified.
+
+Work around the event loss by moving the IRQ acknowledgement into the
+main ISR, adding missing events by explicit level-change detection.

+Subject: [PATCH 331/697] pps: Compatibility hack should be X86-specific
+
+As of [1], using PPS_FETCH on a 64-bit ARM kernel with a 32-bit userland
+is broken, returning a timeout. This is because the requested 4-byte
+alignment for struct pps_ktime_compat (illegal on arm64) results in the
+timeout flags field being uninitialised.
+
+Make the hack specific to X86_64 builds with CONFIG_COMPAT defined.

+The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint

+stuck at the address of the Link TRB, leading to erroneous ring expansion
+events whenever the enqueue pointer wraps to the dequeue position.
+
+If the search for the end of the current TD and ring cycle state lands on
+a Link TRB, move to the next segment.

+ hosts
+
+This reimplements 5a57342 usb: xhci: add VLI_TRB_CACHE_BUG quirk
+
+The downstream implementation required a fair bit of driver surgery to
+allow for truncated ring segments, which needed to shrink by a small
+amount to avoid the cache prefetcher from reading off the end of one
+segment and into another.
+
+An upstream implementation for a similar bug on a different controller
+just doubles the size of the memory allocated for ring segments, which
+is a bit more wasteful (+4K per allocation) but means less code churn.

+Subject: [PATCH 336/697] usb: xhci: add VLI_SS_BULK_OUT_BUG quirk
+
+The VL805 can cause data corruption if a SS Bulk OUT endpoint enters a
+flow-control condition and there are TRBs in the transfer ring that are
+not an integral size of wMaxPacket and the endpoint is behind one or more
+hubs.
+
+This is frequently the case encountered when FAT32 filesystems are
+present on mass-storage devices with cluster sizes of 1 sector, and the
+filesystem is being written to with an aggregate of small files.
+
+The initial implementation of this quirk separated TRBs that didn't
+adhere to this limitation into two - the first a multiple of wMaxPacket
+and the second the 512-byte remainder - in an attempt to force TD
+fragments to align with packet boundaries. This reduced the incidence
+rate of data corruption but did not resolve it.
+
+The fix as recommended by VIA is to disable bursts if this sequence of
+TRBs can occur.
+
+Limit turning off bursts to just USB mass-storage devices by searching
+the device's configuration for an interface with a class type of
+USB_CLASS_MASS_STORAGE.

+Subject: [PATCH 337/697] usb: xhci: add XHCI_VLI_HUB_TT_QUIRK
+
+The integrated USB2.0 hub in the VL805 chipset has a bug where it
+incorrectly determines the remaining available frame time before the
+host next sends a SOF packet with an incremented frame_number.
+
+See the USB2.0 specification sections 11.3 and 11.14.2.3.
+
+The hub's non-periodic TT handler can transmit the IN/OUT handshake
+token too late, so a following 64-byte DATA0/1 packet causes the ACK
+handshake to collide with the propagated SOF. This causes port babble.
+
+Avoid ringing doorbells for vulnerable endpoints during uFrame 7 if the
+TR is Idle to stop one source of babble. An IN transfer for a Running TR
+may happen at any time, so there's not much we can do about that.
+
+Ideally a hub firmware update to properly implement frame timeouts is
+needed, and to avoid spinning for up to 125us when submitting TDs to
+Idle rings.

+xhci: constrain XHCI_VLI_HUB_TT_QUIRK to old firmware versions

+frame time calculation in the hub's TT. Limit applying the quirk to

+Subject: [PATCH 339/697] drm/ili9486: Resolve clash in spi_device_id names
+
+For "Really Good Reasons" [1] the SPI core requires a match
+between compatible device strings and the name in spi_device_id.
+
+The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35"
+and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing,
+so add them.
+
+Compatible string "ilitek,ili9486" is already used by
+staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an
+spi_device_id causes the incorrect module to be loaded, therefore remove
+this id.

+
+gpio: brcmstb: Use bank address as gpiochip label
+
+If the path to the device node is used as gpiochip label then
+gpio-brcmstb instances with multiple banks end up with duplicated
+names. Instead, use a combination of the driver name with the physical
+address of the bank, which is both unique and helpful for devmem
+debugging.

+gpio: mmio: Add DIRECT mode for shared access
+
+The generic MMIO GPIO library uses shadow registers for efficiency,
+but this breaks attempts by raspi-gpio to change other GPIOs in the
+same bank. Add a DIRECT mode that makes fewer assumptions about the
+existing register contents, but note that genuinely simultaneous
+accesses are likely to lose updates.

+
+gpio: brcmstb: Don't always clear interrupt mask
+
+If the GPIO controller is not being used as an interrupt source
+leave the interrupt mask register alone. On BCM2712 it might be used
+to generate interrupts to the VPU firmware, and on other devices it
+doesn't matter since no interrupts will be generated.

+gpio: brcmstb: Use dynamic GPIO base numbers
+
+Forcing a gpiochip to have a fixed base number now leads to a warning
+message. Remove the need to do so by calculating hwirq numbers based
+on bank numbers.

+Subject: [PATCH 344/697] pinctrl: bcm2712 pinctrl/pinconf driver
+
+pinctrl: bcm2712: Reject invalid pulls
+
+Reject attempts to set pulls on aon-sgpios, and fix pull shift
+values.
+
+pinctrl: bcm2712: Add 7712 support, fix 2712 count
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl-bcm2712: add EMMC pins so pulls can be set
+
+These pins have pad controls but not mux controls. They look enough like
+GPIOs to squeeze in at the end of the list though.
+
+pinctrl: bcm2712: correct BCM2712C0 AON_GPIO pad pull control offset
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+pinctrl: bcm2712: on C0 the regular GPIO pad control register moves too
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+pinctrl: bcm2712: Implement (partially) pinconf_get
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Convert to generic pinconf
+
+Remove the legacy brcm,* pin configuration support and replace it with
+a proper generic pinconf interface, using named functions instead of
+alt function numbers. This is nicer for users, less error-prone, and
+immune to some of the C0->D0 changes.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Remove vestigial pull parameter
+
+Now the legacy brcm, pinconf parameters are no longer supported, this
+custom pin config parameter is not needed.

+
+pinctrl: bcm2712: Guard against bad func numbers
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: A better attempt at D0 support
+
+The BCM2712D0 sparse pinctrl maps play havoc with the old GPIO_REGS
+macro, so make the bit positions explicit. And delete the unwanted
+GPIO and pinmux declarations on D0.
+
+Note that a Pi 5 with D0 requires a separate DTS file with "bcm2712d0"
+compatible strings.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Delete base register constants
+
+BCM2712D0 deletes many GPIOs and their associated mux and pad bits,
+so much so that the offsets to the start of the pad control registers
+changes. Remove the constant offsets from the *GPIO_REGS macros,
+compensating by adjusting the per-GPIO values.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Fix for sparse GPIOs
+
+BCM2712D0's sparse GPIO map revealed that it is not safe to treat
+group_selector as the GPIO number - it is an index into the array of
+pinctrl_pin_descs, and the "number" member says which GPIO it refers to.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: bcm2712: Fix for the first valid GPIO
+
+A non-zero mux bit number is used to detect a valid entry in the
+pin_regs tables, but GPIO 0 (GPIO 1 on D0) is a valid GPIO with a mux
+bit number of zero, so add a high-bit on all valid entries to
+distinguish this from an uninitialised row in the table.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+drivers: pinctrl: add BCM2712D0 EMMC pins
+
+The pad control registers are concatenated onto the GPIO pad control
+registers, as with previous steppings.

+Subject: [PATCH 345/697] mmc: brcmstb: add support for BCM2712
+
+BCM2712 has an SD Express capable SDHCI implementation and uses
+the SDIO CFG register block present on other STB chips.
+
+Add plumbing for SD Express handover and BCM2712-specific functions.
+
+Due to the common bus infrastructure between BCM2711 and BCM2712,
+the driver also needs to implement 32-bit IO accessors.
+
+mmc: brcmstb: override card presence if broken-cd is set
+
+Not just if the card is declared as nonremovable.
+
+sdhci: brcmstb: align SD express switchover with SD spec v8.00
+
+Part 1 of the Physical specification, figure 3-24, details the switch
+sequence for cards initially probed as SD. Add a missing check for DAT2
+level after switching VDD2 on.
+
+sdhci: brcmstb: clean up SD Express probe and error handling
+
+Refactor to avoid spurious error messages in dmesg if the requisite SD
+Express DT nodes aren't present.

+mmc: sdhci-brcmstb: only use the delay line PHY for tuneable speeds
+
+The MMC core has a 200MHz core clock which allows the use of DDR50 and
+below without incremental phase tuning. SDR50/SDR104 and the EMMC HS200
+speeds require tuning.

+mmc: sdhci-brcmstb: remove 32-bit accessors for BCM2712
+
+The reason for adding these are lost to the mists of time (and for a
+previous chip revision). Removing these accessors appears to have no ill
+effect on production chips, so get rid of the unnecessary RMW cycles.

+
+drivers: mmc: sdhci-brcmstb: fix usage of SD_PIN_SEL on BCM2712
+
+The SDIO_CFG register SD_PIN_SEL conflates two settings - whether eMMC
+HS or SD UHS timings are applied to the interface, and whether or not
+the card-detect line is functional. SD_PIN_SEL can only be changed when
+the SD clock isn't running, so add a bcm2712-specific clock setup.
+
+Toggling SD_PIN_SEL at runtime means the integrated card-detect feature
+can't be used, so this controller needs a cd-gpios property.
+
+Also fix conditionals for usage of the delay-line PHY - no-1-8-v will
+imply no bits set in hsemmc_mask or uhs_mask, so remove it.

+
+drivers: sdhci-brcmstb: set CQE timer clock frequency
+
+CQHCI keeps track of tags in flight with internal timers, so the clock
+frequency driving the timer needs to be specified. The config registers
+default to 0 (100kHz) which means timeouts will be significantly shorter
+than they should be. Assume the timer clock comes from the controller
+base clock.

+irqchip: bcm2712-mip: add a quick hack to optionally shift MSI vectors
+
+There are two MIP peripherals in bcm2712, the first gets a first-class
+treatment where 64 consecutive GIC SPIs are assigned to all 64 output
+vectors. The second gets an agglomeration of 17 GIC SPIs, but only 8 of
+these are consecutive starting at the 8th output vector.
+
+For now, allow the use of this smaller contiguous range within a larger
+whole.

+Subject: [PATCH 356/697] clk: Add rp1 clock driver
+
+RP1 contains various PLLs and clocks for driving the hardware
+blocks, so add a driver to configure these.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+drivers: clk: rp1: add GPCLK source muxes and additional PLL dividers
+
+General-purpose clocks are routed (via a pad) to a large variety of
+peripheral aux muxes, and themselves gather a large variety of source
+clocks. Entries without a corresponding name string should not be
+selected - they bring out internal test/debug clocks which may be
+intermittent or very high frequency.
+
+As the GPCLK inputs to peripheral muxes come from a pad, differentiate
+the source name from the divider output name. This allows the
+possibility of specifying an off-chip clock source to drive the internal
+peripheral clock.
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+drivers: clk: rp1: constrain clock divider outputs to design maximums
+
+Overclocking peripherals is generally a bad thing to do - so reject any
+attempt to set a clock output higher than it should be.
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+clk: rp1: Reserve pll_audio* for clk_i2s
+
+Prevent all clocks except clk_i2s from using the audio PLLs as sources,
+so that clk_i2s may be allowed to change them as needed.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+clk: rp1: Allow clk_i2s to change the audio PLLs
+
+Add dedicated code allowing the audio PLLs to be changed, enabling
+perfect I2S clock generation. The slowest legal pll_audio_core and
+pll_audio will be selected that leads to the required clk_i2s rate.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+clk: clk-rp1: Add "varsrc" clocks to represent MIPI byte clocks
+
+Add a new class of clocks to RP1 to represent clock sources whose
+frequency changes at run-time as a side-effect of some other driver.
+Specifically this is for the two MIPI DSI byte-clock sources.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+clk: clk-rp1: Don't crash on duplicate clocks
+
+When using DTBs that don't match the kernel version, it's possible for
+clock registration to fail. Handle that failure, in the hope that the
+system can continue to boot, with a suitable error message.

+Subject: [PATCH 358/697] pinctrl: Add rp1 driver
+
+RP1 exposes GPIOs. Add a pinctrl driver to allow control of those.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Use the correct per-bank GPIO base
+
+The GPIO start for each bank - min_gpio - must be used in the IRQ
+handler.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Allow legacy brcm,pins on all banks
+
+Support the use of the brcm,pins property for GPIOs in banks 1 and 2,
+but only for inputs and outputs - no other legacy mapping.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Support interrupt CPU affinity
+
+See: https://github.com/raspberrypi/linux/issues/6077
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Clear events when setting IRQ type
+
+When setting the interrupt type, it is unlikely that any latched events
+are of interest, so clear them.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Add strict_gpiod module parameter
+
+Setting strict_gpiod to Y makes libgpiod and the gpiod utilities behave
+as documented, i.e. pins are returned to being GPIO inputs when they are
+released.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+pinctrl: rp1: Use persist_gpio_outputs
+
+Following 8ff05989b44e1a8f7d2bbe67320990ebc2fbb5e5, adopt the same
+parameter name but with the opposite default.

+Subject: [PATCH 359/697] serial: pl011: rp1 uart support
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+ARM: pl011: Add rs485 to the RP1 support
+
+pl011_axi_probe, added for RP1 support, lacks the rs485 additions that
+appeared during its development.
+
+Signed-off-by: Phil Elwell <phil@raspberrypi.com>
+
+tty/serial: pl011: restrict RX burst FIFO threshold
+
+If the associated DMA controller has lower burst length support than the
+level the FIFO is set to, then bytes will be left in the RX FIFO at the
+end of a DMA block - requiring a round-trip through the timeout interrupt
+handler rather than an end-of-block DMA interrupt.
+
+Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
+
+tty/serial: pl011: Also unregister pl011_axi_platform_driver
+
+See: https://github.com/raspberrypi/linux/issues/6379

+Subject: [PATCH 362/697] i2c: designware: Add SMBUS quick command support
+
+The SMBUS emulation code turns an SMBUS quick command into a zero-
+length read. This controller can't do zero length accesses, but it
+can do quick commands, so reverse the emulation. The alternative
+would be to properly implement the SMBUS support but that is a lot
+more work, and unnecessary just to get i2cdetect working.

+Subject: [PATCH 363/697] dmaengine: dw-axi-dmac: Fixes for RP1
+
+Don't assume that DMA addresses of devices are the same as their
+physical addresses - convert correctly.
+
+The CFG2 register layout is used when there are more than 8 channels,
+but also when configured for more than 16 target peripheral devices
+because the index of the handshake signal has to be made wider.
+
+Reset the DMAC on probe
+
+The driver goes to the trouble of tracking when transfers have been
+paused, but then doesn't report that state when queried.
+
+Not having APB registers is not an error - for most use cases it's
+not even of interest, it's expected. Demote the message to debug level,
+which is disabled by default.
+
+Each channel has a descriptor pool, which is shared between transfers.
+It is unsafe to treat the total number of descriptors allocated from a
+pool as the number allocated to a specific transfer; doing so leads
+to releasing buffers that shouldn't be released and walking off the
+ends of descriptor lists. Instead, give each transfer descriptor its
+own count.
+
+Support partial transfers:
+Some use cases involve streaming from a device where the transfer only
+proceeds when the device's FIFO occupancy exceeds a certain threshold.
+In such cases (e.g. when pulling data from a UART) it is important to
+know how much data has been transferred so far, in order that remaining
+bytes can be read from the FIFO directly by software.
+
+Add the necessary code to provide this "residue" value with a finer,
+sub-transfer granularity.
+
+In order to prevent the occasional byte getting stuck in the DMA
+controller's internal buffers, restrict the destination memory width
+to the source register width.

+
+dmaengine: dw-axi-dmac: Fix a non-atomic update
+
+dw_axi_dma_interrupt disables interrupts for the duration of the channel
+handling. It does so by clearing a bit in the DMA_CFG register - an
+action that involves a read-modify-write. That in itself would be safe
+because there will be no further interrupts, hence no reentrancy, were
+it the only bit of code accessing that register.
+
+The only neighbour of INT_EN is DMAC_EN - the main enable for the block.
+That's not the sort of thing you would expect to be modified during the
+normal course of operation, but bizarrely it is set at the start of the
+transfer of every block, in axi_chan_block_xfer_star, by a call to
+axi_dma_enable. This can lead to INT_EN being accidentally cleared,
+which causes all DMA transfers to time out.
+
+One might think that the enabling was being delayed until the first
+transfer, but the probe function calls axi_dma_resume which in turn
+calls axi_dma_enable, so that isn't the case.
+
+Fix the atomicity problem by removing the spurious call to
+axi_dma_enable.

+
+Add support for the RP1 DSI hardware.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm/rp1: depends on, instead of select, MFD_RP1
+
+According to kconfig-language.txt [1], select should be used only for
+"non-visible symbols ... and for symbols with no dependencies". Since
+MFD_RP1 both is visible and has a dependency, "select" should not be
+used and "depends on" should be used instead.
+
+In particular, this fixes the build of this kernel tree on NixOS, where
+its kernel config system will try to answer 'M' to as many config as
+possible.

+
+DRM: rp1: rp1-dsi: Fix escape clock divider and timeouts.
+
+Escape clock divider was fixed at 5, which is correct at 800Mbps/lane
+but increasingly out of spec for higher rates. Compute it correctly.
+
+High speed timeout was fixed at 5*512 == 2560 byte-clocks per lane.
+Compute it conservatively to be 8/7 times the line period (assuming
+there will be a transition to LP some time during each scanline?)
+keeping the old value as a lower bound. Increase LPRX TO to 1024,
+and BTA TO to 0xb00 (same value as in bridge/synopsys/dw-mipi-dsi).
+
+(No change to LP_CMD_TIM. To do: compute this correctly.)
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm: rp1: rp1-dsi: Switch to PLL_SYS source for DPI when 8 * lanes > bpp
+
+To support 4 lanes, re-parent DPI clock source between DSI byteclock
+(using the new "variable sources" defined in clk-rp1) and PLL_SYS.
+This is to cover cases in which byteclock < pixclock <= 200MHz.
+
+Tidying: All frequencies now in Hz (not kHz), where DSI speed is now
+represented by byteclock to simplify arithmetic. Clamp DPI and byte
+clocks to their legal ranges; fix up HSTX timeout to avoid an unsafe
+assumption that it would return to LP state for every scanline.
+
+Because of RP1's clock topology, the ratio between DSI and DPI clocks
+may not be exact with 3 or 4 lanes, leading to slightly irregular
+timings each time DSI switches between HS and LP states. Tweak to
+inhibit LP during Horizontal BP when sync pulses were requested.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm: rp1: rp1-dsi: Add DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888
+
+Android requires this.
+As the underlying hardware doesn't support alpha blending,
+we ignore the alpha value.
+
+Signed-off-by: Jan Kehren <jan.kehren@emteria.com>
+
+drivers: drm: rp1-dsi: Implement more DSI options and flags
+
+Now implementing:
+- Per-command selection of LP or HS for commands (previously LP)
+- EoTp transmission option (previously EoTp was always disabled)
+- Non-continuous clock option (previously always continuous)
+- Per-command enabling of ACK request (in command mode only)
+
+Make a plausible (and possibly correct) attempt to measure the
+longest LP command that will fit into vertical blanking lines.
+
+DON'T set both "Burst Mode" and "Sync Events" flags together.
+This is redundant in the standard IP; in this RP1 variant it
+would enable Sync Pulses but may break with some video timings.

+Subject: [PATCH 367/697] drm: Add RP1 DPI driver
+
+Add support for the RP1 DPI hardware.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm/rp1: depends on, instead of select, MFD_RP1
+
+According to kconfig-language.txt [1], select should be used only for
+"non-visible symbols ... and for symbols with no dependencies". Since
+MFD_RP1 both is visible and has a dependency, "select" should not be
+used and "depends on" should be used instead.
+
+In particular, this fixes the build of this kernel tree on NixOS, where
+its kernel config system will try to answer 'M' to as many config as
+possible.

+
+drm: rp1: VEC and DPI drivers: Fix bug #5901
+
+Rework probe() to use devm_drm_dev_alloc(), embedding the DRM
+device in the DPI or VEC device as now seems to be recommended.
+
+Change order of resource allocation and driver initialization.
+This prevents it trying to write to an unmapped register during
+clean-up, which previously could crash.

+
+This new format corresponds to the Raspberry Pi legacy DPI mode 3.

+
+drm: rp1: rp1-dpi: Add DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888
+
+Android requires this.
+As the underlying hardware doesn't support alpha blending,

+Subject: [PATCH 368/697] drm: Add RP1 VEC driver
+
+Add support for the RP1 VEC hardware.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm: rp1: rp1-vec: Allow non-standard modes with various crops
+
+Tweak sync timings in the advertised modelines.
+
+Accept other, custom modes, provided they fit within the active
+area of one of the existing hardware-supported TV modes.
+
+Instead of always padding symmetrically, try to respect the user's
+[hv]sync_start values, allowing the image to be shifted around
+the screen (to fine-tune overscan correction).

+
+drm/rp1: depends on, instead of select, MFD_RP1
+
+According to kconfig-language.txt [1], select should be used only for
+"non-visible symbols ... and for symbols with no dependencies". Since
+MFD_RP1 both is visible and has a dependency, "select" should not be
+used and "depends on" should be used instead.
+
+In particular, this fixes the build of this kernel tree on NixOS, where
+its kernel config system will try to answer 'M' to as many config as
+possible.

+
+drm: rp1: Use tv_mode from the command line and fix for Linux 6.6
+
+Use the standard enum drm_connector_tv_mode instead of a private
+enum and switch from the legacy to the standard tv_mode property.
+
+Remove the module parameter "tv_norm". Instead, get tv_mode from
+the command line and make this the connector's default TV mode.
+
+Don't restrict the choice of modes based on tv_mode, but interpret
+nonstandard combinations as NTSC or PAL, depending on resolution.
+Thus the default tv_mode=NTSC effectively means "Auto".
+
+Tweak the advertised horizontal timings for 625/50 to match Rec.601

+
+drm: rp1: VEC and DPI drivers: Fix bug #5901
+
+Rework probe() to use devm_drm_dev_alloc(), embedding the DRM
+device in the DPI or VEC device as now seems to be recommended.
+
+Change order of resource allocation and driver initialization.
+This prevents it trying to write to an unmapped register during
+clean-up, which previously could crash.

+
+drm: rp1: vec: Support more video modes in the RP1 VEC driver
+
+Support a wider range of pixel clock rates. The driver will round
+pixclock up to 108MHz/n but tries to honour the desired image width
+and position (of the centre of the display relative to HSYNC_STARTs).
+This adds complexity but removes the need for separate 13.5MHz and
+15.428MHz modes.
+
+Support "fake" double-rate progressive modes (in which only every
+2nd scanline is displayed). To work around aspect ratio issues.
+
+Add Monochrome TV mode support. Add "vintage" modes (544x380i for
+System A; 848x738i for System E) when configured for Monochrome.
+
+Add a way to create a "custom" display mode from a module parameter.
+
+Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>
+
+drm: rp1: rp1-vec: Add DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888
+
+Android requires this.
+As the underlying hardware doesn't support alpha blending,
+we ignore the alpha value.
+
+Signed-off-by: Jan Kehren <jan.kehren@emteria.com>
+
+drivers: drm: rp1-vec: Increase width limit, for PAL 16:9 @ 18MHz
+
+There was no technical reason for the DRM mode's width limit of 848;
+increase it to 960 (720*18MHz/13.5MHz) to support ~square pixels on
+16:9 screens. Tweak the PAL active window to start slightly earlier.
+(The maximum number of visible columns at 18MHz is about 942.)

+media: rp1: cfe: Fix use of freed memory on errors
+
+cfe_probe_complete() calls cfe_put() on both success and fail code paths.
+This works for the success path, but causes the cfe_device struct to be
+freed, even if it will be used later in the teardown code.
+
+Fix this by making the ref handling a bit saner: Let the video nodes
+have the refs as they do now, but also keep a ref in the "main" driver,
+released only at cfe_remove() time. This way the driver does not depend
+on the video nodes keeping the refs.

+media: rp1: cfe: Fix width & height in cfe_start_channel()
+
+The logic for handling width & height in cfe_start_channel() is somewhat
+odd and, afaics, broken. The code reads:
+
+bool start_fe = is_fe_enabled(cfe) &&
+                test_all_nodes(cfe, NODE_ENABLED, NODE_STREAMING);
+
+if (start_fe || is_image_output_node(node)) {
+        width = node->fmt.fmt.pix.width;
+        height = node->fmt.fmt.pix.height;
+}
+
+cfe_start_channel() is called for all video nodes that will be used. So
+this means that if, say, fe_stats is enabled as the last node, start_fe
+will be true, and width and height will be taken from fe_stats' node.
+The width and height will thus contain garbage, which then gets
+programmed to the csi2 registers.
+
+It seems that this often still works fine, though, probably if the width
+& height are large enough.
+
+Drop the above code, and instead get the width & height from the csi2
+subdev's sink pad for the csi2 channel that is used. For metadata the
+width & height will be 0 as before.

+media: rp1: cfe: Dual purpose video nodes
+
+The RP1 CSI-2 DMA can capture both video and metadata just fine, but at
+the moment the video nodes are only set to support either video or
+metadata.
+
+Make the changes to support both video and metadata. This mostly means
+tracking both video format and metadata format separately for each video
+node, and using vb2_queue_change_type() to change the vb2 queue type
+when needed.
+
+Briefly, this means that the user can get/set both video and meta
+formats to a single video node. The vb2 queue buffer type will be
+changed when the user calls REQBUFS or CREATE_BUFS ioctls. This buffer
+type will be then used as the "mode" for the video node when the user
+starts the streaming, and based on that either the video or the meta
+format will be used.
+
+A bunch of macros are added (node_supports_xxx()), which tell if a node
+can support a particular mode, whereas the existing macros
+(is_xxx_node()) will tell if the node is currently in a particular mode.
+Note that the latter will only work correctly between the start of the
+streaming and the end of the streaming, and thus should be only used in
+those code paths.
+
+However, as the userspace (libcamera) does not support dual purpose
+video nodes, for the time being let's keep the second video node as
+V4L2_CAP_META_CAPTURE only to keep the userspace working.

+ sck-idle-input
+
+Formerly, if configured using DT, CS GPIOs were driven from spi.c
+and it was possible for CS to be asserted (low) *before* starting
+to drive SCK. CS GPIOs have been brought under control of this
+driver in both ACPI and DT cases, with a fixup for GPIO polarity.

+
+The BCM2712 has a DMA-Lite controller that is basically a BCM2835-style
+DMA controller that supports 40 bits DMA addresses.
+
+We need it for HDMI audio to work, but this breaks BCM2835-38 so we
+should rework this later.

+Subject: [PATCH 381/697] drivers: iommu: Add BCM2712 IOMMU
+
+Add a driver for BCM2712 IOMMUs.
+There is a small driver for the Shared IOMMU TLB Cache.
+Each IOMMU instance is a separate device.
+
+IOMMUs are set up with a "pass-through" range covering
+the lowest 40BGytes (which should cover all of SDRAM)
+for the benefit of non-IOMMU-aware devices that share
+a physical IOMMU; and translation for addresses in the
+range 40GB to 42GB.
+
+An optional parameter adds a DMA offset (which otherwise
+would be lost?) to virtual addresses for DMA masters on a
+bus such as PCIe.

+
+iommu: bcm2712-iommu: Map and unmap multiple pages in a single call
+
+For efficiency, the map_pages() and unmap_pages() calls now pay
+attention to their "count" argument.
+
+Remove a special case for a "pass-through" address range, which
+the DMA/IOMMU subsystem isn't told exists and should never use.
+
+Fix a bug where we omitted to set *mapped to 0 in error cases.
+Minor style fixes and tidying.

+iommu/bcm2712: don't allow building as module
+
+Since bcm2712-iommu{,-cache}.c doesn't have usual module descriptors
+such as `MODULE_LICENSE`, configuring this as 'M' fails the build with
+`ERROR: modpost: missing MODULE_LICENSE() in <...>/bcm2712-iommu.o`.
+Since it seems like the code is not intended to be built as a module
+anyway (it registers the driver with `builtin_platform_driver()`), don't
+allow building this code as a module.

+ controller
+
+We currently see these regularly:
+[   25.157560] irq 31, desc: 00000000c15e6d2c, depth: 0, count: 0, unhandled: 0
+[   25.164658] ->handle_irq():  00000000b1775675, brcmstb_l2_intc_irq_handle+0x0/0x1a8
+[   25.172352] ->irq_data.chip(): 00000000fea59f1c, gic_chip_mode1+0x0/0x108
+[   25.179166] ->action(): 000000003eda6d6f
+[   25.183096] ->action->handler(): 000000002c09e646, bad_chained_irq+0x0/0x58
+[   25.190084]      IRQ_LEVEL set
+[   25.193142]    IRQ_NOPROBE set
+[   25.196198]  IRQ_NOREQUEST set
+[   25.199255]   IRQ_NOTHREAD set
+
+with:
+$ cat /proc/interrupts  | grep 31:
+ 31:          1          0          0          0     GICv2 129 Level     (null)
+
+The interrupt is described in DT with IRQ_TYPE_LEVEL_HIGH
+
+But the current compatible string uses the controller in edge triggered mode
+(as that config matches our register layout).
+
+Add a new compatible structure for level driven interrupt with our register layout.
+
+We had already been using this compatible string in device tree, so no change needed
+there.

+Subject: [PATCH 383/697] rtc: rtc-rpi: Add simple RTC driver for Raspberry Pi
+
+This supports setting and reading the real time clock
+and supports wakeup alarms.
+
+To support wake up alarms you want this bootloader config:
+ POWER_OFF_ON_HALT=1
+ WAKE_ON_GPIO=0
+
+You can test with:
+  echo +600 | sudo tee /sys/class/rtc/rtc0/wakealarm
+  sudo halt
+
+That will halt (in an almost no power state),
+then wake and restart after 10 minutes.

+drivers: rtc-rpi: add battery charge circuit control and readback
+
+Parse devicetree for a charger voltage and apply it. If nonzero and a
+valid voltage, the firmware will enable charging, otherwise the charger
+circuit is disabled.
+
+Add sysfs attributes to read back the supported charge voltage range,
+the measured battery voltage, and the charger setpoint.

++* Raspberry Pi RTC
++
++This is a Linux interface to an RTC managed by firmware, hence it's
++virtual from a Linux perspective.
++
++The interface uses the firmware mailbox api to access the RTC registers.
++
++Required properties:
++compatible: should be "raspberrypi,rpi-rtc"
++firmware:   Reference to the RPi firmware device node.
++
++Optional property:
++trickle-charge-microvolt: specify a trickle charge voltage for the backup
++                          battery in microvolts.
++
++Example:
++
++	rpi_rtc: rpi_rtc {
++		compatible = "raspberrypi,rpi-rtc";
++		firmware = <&firmware>;
++		trickle-charge-microvolt = <3000000>;
++	};

+Subject: [PATCH 393/697] media: i2c: ov9282: Read chip ID via 2 reads
+
+Vision Components have made an OV9281 module which blocks reading
+back the majority of registers to comply with NDAs, and in doing
+so doesn't allow auto-increment register reading as used when
+reading the chip ID.
+
+Use two reads and manually combine the results.

+Subject: [PATCH 398/697] drivers: mmc: sdhci: add SPURIOUS_INT_RESP quirk
+
+Certain controllers (dwc-mshc) generate timeout conditions separately to
+command-completion conditions, where the end result is interrupts are
+separated in time depending on the current SDCLK frequency.
+
+This causes spurious interrupts if SDCLK is slow compared to the CPU's
+ability to process and return from interrupt. This occurs during card
+probe with an empty slot where all commands that would generate a
+response time out.
+
+Add a quirk to squelch command response interrupts when a command
+timeout interrupt is received.

+
+With the new support for a chain of sys_off handlers, gpio-poweroff
+does not disable a normal shutdown (though it does delay it). There

+Subject: [PATCH 403/697] xhci: Use more event ring segment table entries
+
+Users have reported log spam created by "Event Ring Full" xHC event
+TRBs. These are caused by interrupt latency in conjunction with a very
+busy set of devices on the bus. The errors are benign, but throughput
+will suffer as the xHC will pause processing of transfers until the
+event ring is drained by the kernel. Expand the number of event TRB slots
+available by increasing the number of event ring segments in the ERST.
+
+Controllers have a hardware-defined limit as to the number of ERST
+entries they can process, so make the actual number in use
+min(ERST_MAX_SEGS, hw_max).

+
+Step wise governor increases the mitigation level when the temperature
+goes above a threshold and will decrease the mitigation when the
+temperature falls below the threshold. If it were a case, where the
+temperature hovers around a threshold, the mitigation will be applied
+and removed at every iteration. This reaction to the temperature is
+inefficient for performance.
+
+The use of hysteresis temperature could avoid this ping-pong of
+mitigation by relaxing the mitigation to happen only when the
+temperature goes below this lower hysteresis value.

+Subject: [PATCH 413/697] spi: bcm2835: Support spi0-0cs and SPI_NO_CS mode
+
+The forced conversion of native CS lines into software CS lines is done
+whether or not the controller has been given any CS lines to use. This
+breaks the use of the spi0-0cs overlay to prevent SPI from claiming any
+CS lines, particularly with spidev which doesn't pass in the SPI_NO_CS
+flag at creation.
+
+Use the presence of an empty cs-gpios property as an indication that no
+CS lines should be used, bypassing the native CS conversion code.
+
+See: https://github.com/raspberrypi/linux/issues/5835

+Subject: [PATCH 423/697] i2c: mux: Add support for generic base-nr property
+
+i2c_mux_add_adapter takes a force_nr parameter that allows an explicit
+bus number to be associated with a channel. However, only i2c-mux-reg
+and i2c-mux-gpio make use of it.
+
+To help with situations where it is desirable to have a fixed, known
+base address for the channels of a mux, create a "base-nr" property.
+When force_nr is 0 and base-nr is set and non-zero, form a force_nr
+value from the sum of base-nr and the channel ID.

+Subject: [PATCH 424/697] non-upstream: support DS1 exit firmware re-download
+
+In deep sleep mode (DS1) ARM is off and once exit trigger comes than
+mailbox Interrupt comes to host and whole reinitiation should be done
+in the ARM to start TX/RX.
+
+Also fix below issus for DS1 exit:
+1. Sent Tx Control frame only after firmware redownload complete (check
+F2 Ready before sending Tx Control frame to Firmware)
+2. intermittent High DS1 TX Exit latency time (almost 3sec) ==> This is
+fixed by skipping host Mailbox interrupt Multiple times (ulp state
+mechanism)
+3. RX GlOM save/restore in Firmware
+4. Add ULP event enable & event_msgs_ext iovar configuration in FMAC
+5. Add ULP_EVENT_RECV state machine for sbwad support
+6. Support 2 Byte Shared memory read for DS1 Exit HUDI implementation

+Subject: [PATCH 425/697] brcmfmac: Fix interoperating DPP and other encryption
+ network access
+
+1. If firmware supports 4-way handshake offload but not supports DPP
+4-way offload, when user first connects encryption network, driver will
+set "sup_wpa 1" to firmware, but it will further result in DPP
+connection failure since firmware won't send EAPOL frame to host.
+
+2. Fix DPP AP mode handling action frames.
+
+3. For some firmware without fwsup support, the join procedure will be
+skipped due to "sup_wpa" iovar returning not-support. Check the fwsup
+feature before do such iovar.

+Subject: [PATCH 427/697] brcmfmac: Fix 802.1x
+
+Commit 7d239fbf9d4 broke 802.1X authentication by setting
+profile->use_fwsup = NONE whenever PSK is not used. However
+802.1X does not use PSK and requires profile->use_fwsup set
+to 1X, or brcmf_cfg80211_set_pmk() fails. Fix this by checking
+that profile->use_fwsup is not already set to 1X and avoid
+setting it to NONE in that case.
+
+Fixes: 7d239fbf9d4 (brcmfmac: Fix interoperating DPP and other encryption network access)
+Fixes: https://github.com/raspberrypi/linux/issues/5964

+Subject: [PATCH 428/697] mmc: bcm2835-sdhost: use Host Software Queueing
+ mechanism
+
+See commit 511ce378e16f ("mmc: Add MMC host software queue support")
+
+Introduced in 5.8, this feature lets the block layer issue up to 2
+pending requests to the MMC layer which in certain cases can improve
+throughput, but in the case of this driver can significantly reduce
+context switching when performing random reads.
+
+On bcm2837 with a performant class A1 card, context switches under FIO
+random 4k reads go from ~8800 per second to ~5800, with a reduction in
+hardIRQs per second from ~5800 to ~4000. There is no appreciable
+difference in throughput.
+
+For bcm2835, and for workloads other than random read, HSQ is a wash in
+terms of throughput and CPU load.
+
+So, use it by default.

+
+Application class A2 cards require CQ to be enabled to realise their
+stated performance figures. Add support to enable/disable card CQ via
+the Performance Enhancement extension register, and cater for the slight

+Subject: [PATCH 433/697] drivers: mmc: cqhci: clear CQHCI_CTL if halt fails
+
+The eMMC spec says that in certain circumstances the controller can't
+respond to a halt request - in practice, this occurs if a CMD
+timeout happens (card went away/crashed).
+
+Clear the halt request by writing 0 to CQHCI_CTL. Also fix a logic error
+testing for halt in cqhci_request.

+Explicitly detect the card after CQE has halted and bail if it's not

+Subject: [PATCH 442/697] mmc: restrict posted write counts for SD cards in CQ
+ mode
+
+Command Queueing requires Write Cache and Power off Notification support
+from the card - but using the write cache forms a contract with the host
+whereby the card expects to be told about impending power-down.
+
+The implication is that (for performance) the card can do unsafe things
+with pending write data - including reordering what gets committed to
+nonvolatile storage at what time.
+
+Exposed SD slots and platforms powered by hotpluggable means (i.e.
+Raspberry Pis) can't guarantee that surprise removal won't happen.
+
+To limit the scope for cards to invent new ways to trash filesystems,
+limit pending writes to 1 (equivalent to the non-CQ behaviour).

+
+Also, cqe_enable is 1 if hsq is enabled as hsq substitutes the cqhci

+Subject: [PATCH 444/697] drivers: mmc: disable write-caching on Samsung 2023
+ model year SD cards
+
+Samsung EVO Plus, Pro Plus and Evo Ultimate cards of this era appear to
+have a broken cache-flush implementation when operating in CQ mode.
+
+Unfortunately the cards seem to use a separate CID name string for every
+variant and capacity, so nobble the cache feature for this MANFID, OEMID
+and year. Turning this off seems to have negligible impact on
+random-write throughput in non-CQ mode.

+Subject: [PATCH 448/697] i2c: designware: Add support for bus clear feature
+
+Newer versions of the DesignWare I2C block support the detection of
+stuck signals, and a mechanism to recover from them. Add the required
+software support to the driver.
+
+This change was prompted by the observation that reading a single byte
+from register 0 of a VEML7700 seems to cause it to issue an ACK too
+early, and the controller to complain about losing arbitration. There
+is a suspicion that this may be a more widespread problem, but at least
+this patch prevents the bus from locking up.

+
+"rotation" is listed as a standard property of panels in panel-common.yaml,
+therefore it would be logical to process that from within the core
+code should a panel driver not implement the get_orientation hook.
+
+Call of_drm_get_panel_orientation from
+drm_connector_set_orientation_from_panel to get that information.
+
+This removes the need for any boiler-plate in panel drivers for calling
+drm_connector_set_orientation_from_panel or
+drm_connector_set_panel_orientation.

+
+As with many microcontrollers, the panel wants to use clock
+stretching during a read so that the appropriate return value
+can be generated and programmed into the hardware.
+With Pi0-3 really not supporting clock stretching, this resulted

+
+Insert a delay between the write and the read to give the firmware
+a chance to generate the relevant return value.

+Subject: [PATCH 463/697] drm/bridge: panel: Name an associated backlight
+ device
+
+Pass the DRM connector name to any configured backlight
+device so that userspace can associate the two items.
+
+Ideally this should be in drm_panel, but it is bridge/panel
+that creates the drm_connector and therefore knows the name.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/bridge: panel: Ensure backlight is reachable
+
+Ensure that the various options of modules vs builtin results
+in being able to call into the backlight code.
+
+https://github.com/raspberrypi/linux/issues/6198

+Subject: [PATCH 470/697] staging: vc04_services: vc-sm-cma: Remove deprecated
+ header
+
+The vchiq_connected.h header was removed in f875976ecf45 ("staging:
+vc04_services: Drop vchiq_connected.[ch] files") to simplify the
+implementation.
+
+Update the vc_sm driver accordingly which can still use the same
+functions through the vchiq_arm.h header declarations.
+
+Fixes: b1ab7a05eb6c ("staging: vc04_services: Add new vc-sm-cma driver")

+Subject: [PATCH 471/697] staging: vc04_services: vc-sm-cma: Drop include
+ Makefile directive
+
+Drop the include directive. They can break the build, when one only
+wants to build a subdirectory. Replace with "../" for the includes in
+the vc_sm files instead.
+
+The fix is equivalent to the four patches between 29d49a76c5b2
+("staging: vc04_services: bcm2835-audio: Drop include Makefile
+directive")...2529ca211402 ("staging: vc04_services: interface: Drop

+Subject: [PATCH 485/697] spi: Add a driver for the RPI RP2040 GPIO bridge
+
+The Raspberry Pi RP2040 GPIO bridge is an I2C-attached device exposing
+both a Tx-only SPI controller, and a GPIO controller.
+
+Due to the relative difference in transfer rates between standard-mode
+I2C and SPI, the GPIO bridge makes use of 12 MiB of non-volatile storage
+to cache repeated transfers. This cache is arranged in ~8 KiB blocks and
+is addressed by the MD5 digest of the data contained therein.
+
+Optionally, this driver is able to take advantage of Raspberry Pi RP1
+GPIOs to achieve faster than I2C data transfer rates.

+Useful for tracking upload progress via userspace.
+
+Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
+
+spi: rp2040-gpio-bridge: add missing MD5 dependency
+
+rp2040-gpio-bridge relies on the md5 crypto driver. This dependency
+cannot be determined automatically as rp2040-gpio-bridge does not
+use any of md5's symbols directly.
+
+Declare a soft 'pre' dependency on md5 to ensure that it is included and
+loaded before rp2040-gpio-bridge.

+Subject: [PATCH 486/697] dmaengine: dw-axi-dmac: Honour snps,block-size
+
+The snps,block-size DT property declares the maximum block size for each
+channel of the dw-axi-dmac. However, the driver ignores these when
+setting max_seg_size and uses MAX_BLOCK_SIZE (4096) instead.
+
+To take advantage of the efficiencies of larger blocks, calculate the
+minimum block size across all channels and use that instead.
+
+See: https://github.com/raspberrypi/linux/issues/6256

+ driver as legacy
+
+Whilst the Unicam driver has now been upstreamed it only supports
+configuration via Media Controller (not driven from the /dev/videoN
+node), which makes life significantly harder for simple devices such
+as mono sensors, and HDMI or analogue video to CSI2 bridge chips
+(eg TC358743 and ADV7282M).

+Fix up the downstream driver so that it builds, reinstate the links

+(VIDEO_BCM2835_UNICAM_LEGACY).

+
+Move the "brcm,bcm2835-unicam" compatible from the upstream driver
+to the old downstream version so that users can run libcamera
+against 6.10.
+Once the libcamera changes have been merged this can be reverted
+to use the upstream driver.
+
+If using the non-legacy compatible then assume we want to use
+media-controller API for configuration.

+Subject: [PATCH 493/697] pinctrl: rp1: jump through hoops to avoid PCIe
+ latency issues
+
+Automatic link power saving plus the ability of a root complex to buffer
+pending posted write transfers (and consider them complete before being
+transmitted on the wire) causes compression of updates to GPIO state.
+
+The large bandwidth of a Gen 2 x4 link means the writes toggle state
+inside RP1 as fast as it can go (~20MHz), which is bad for applications
+wanting bitbash with at least a few microseconds of delay between
+updates.
+
+By tailoring IO access patterns to a special Root Complex register,
+writes to GPIOs can be stalled until the link wakes - meaning all writes
+end up with a reasonably consistent minimum pacing (~200ns).
+
+Additionally, write barriers have no effect other than to arbitrarily
+delay some writes by a small, variable amount - so remove the vast
+majority of these in areas that could be hot-paths.
+
+Although the IO memory is mapped with Device strongly-ordered semantics,
+this doesn't prevent the splitter inside BCM2712 from letting an MMIO
+read request to a GPIO register get ahead of the pacing writes to the
+Root Complex register. So each pin state read must flush writes out to
+the Outer-Shareable domain.

+Subject: [PATCH 496/697] spi: dw: don't immediately kill DMA transfers if an
+ error occurs
+
+Disabling the peripheral resets controller state which has a dangerous
+side-effect of disabling the DMA handshake interface while it is active.
+This can cause DMA channels to hang.
+
+The error recovery pathway will wait for DMA to stop and reset the chip
+anyway, so mask further FIFO interrupts and let the transfer finish
+gracefully.

+Subject: [PATCH 497/697] drivers: dw-axi-dmac: make more sensible choices
+ about memory accesses
+
+There's no real need to constrain MEM access widths to 32-bit (or
+narrower), as the DMAC is intelligent enough to size memory accesses
+appropriately. Wider accesses are more efficient.
+
+Similarly, MEM burst lengths don't need to be a function of DEV burst
+lengths - the DMAC packs/unpacks data into/from its internal channel
+FIFOs appropriately. Longer accesses are more efficient.
+
+However, the DMAC doesn't have complete support for unaligned accesses,
+and blocks are always defined in integer multiples of SRC_WIDTH, so odd
+source lengths or buffer alignments will prevent wide accesses being
+used, as before.
+
+There is an implicit requirement to limit requested DEV read burst
+lengths to less than the hardware's maximum configured MSIZE - otherwise
+RX data will be left over at the end of a block. There is no config
+register that reports this value, so the AXI burst length parameter is
+used to produce a facsimile of it. Warn if such a request arrives that
+doesn't respect this.

+Subject: [PATCH 499/697] sound/soc: dwc-i2s: choose FIFO thresholds based on
+ DMA burst constraints
+
+Valid ranges for the I2S peripheral's FIFO configuration include a depth
+of 16 - unconditionally setting the burst length to 16 with a fifo
+threshold of size/2 will cause under/overflows.
+
+For DMA engines with restricted capabilities the requested burst length
+and FIFO thresholds need to be adjusted downward accordingly.
+
+Both the RX and TX FIFOs operate on "less-than" thresholds. Setting the
+TX threshold to fifo_size minus burst means the FIFO is kept nearly-full.

++description: |-
++  The Sony IMX500 is a stacked 1/2.3-inch CMOS digital image sensor and inbuilt
++  AI processor with an active array CNN (Convolutional Neural Network) inference
++  engine.  The native sensor size is 4056H x 3040V, and the module also contains
++  an in-built ISP for the CNN. The module is programmable through an I2C
++  interface with firmware and neural network uploads being made over SPI. The
++  default I2C address is 0x1A, with an address of 0x10 being selectable via
++  SLASEL. The module also has a second I2C interface available with a fixed
++  address of 0x36.  Image data is sent through MIPI CSI-2, which is configured
++  as either 2 or 4 data lanes.

+Subject: [PATCH 509/697] media: i2c: ov5647: Add control of V4L2_CID_HBLANK
+
+The driver did expose V4L2_CID_HBLANK, but as a READ_ONLY control.
+
+The sensor only uses the HTS register to control the line length,
+so convert this control to read/write, with the appropriate ranges.
+Adopt the old fixed values as the minimum values permitted in each
+mode to avoid issues of it not streaming.
+
+This should allow exposure times up to ~3 seconds (up from ~1sec).

+Subject: [PATCH 510/697] drm: panel: ili9881: Correct symmetry on
+ enable/disable return codes
+
+ili9881c_enable is always returning 0.
+
+ili9881c_disable was returning the error code from
+mipi_dsi_dcs_set_display_off.
+If non-zero, the drm_panel framework will leave the panel marked as
+enabled, and not run the enable hook next time around. That isn't
+helpful, particularly as we're expecting unprepare to disable

+Subject: [PATCH 511/697] drm: panel: ili9881: Add option to reconfigure setup
+ commands
+
+The driver is typically asking for LP commands, but then tries
+to send set_display_[on|off] from enable/disable when the host
+will be in HS mode.
+It also sends shutdown commands just before it asserts reset and
+disables the regulator, which is rather redundant.
+
+Add an option to configure these two choices from the panel_desc.

+Subject: [PATCH 513/697] NotForUpstream: media: video-mux: Propagate controls
+ to source
+
+The i.MX8MP makes calls on it's source device to determine
+the link-frequency that should be configured on the CSI2 receiver.
+
+When the source is behind a video mux, we need to pass this call through
+to the connected device.
+
+Map the control handler of the source device to the video-mux,
+essentially proxying all controls on the mux to the device which has
+it's link enabled.

+
+The current order of locking between the driver mutex and the v4l2

+Subject: [PATCH 522/697] drivers: media: bcm2835_isp: Cache LS table dmabuf
+
+Clients such as libcamera do not change the LS table dmabuf on every
+frame. In such cases instead of mapping/remapping the same dmabuf on
+every frame to send to the firmware, cache the dmabuf once and only
+update and remap if the dmabuf has been changed by the userland client.

+Subject: [PATCH 526/697] usb: dwc3: core: add support for setting NAK
+ enhancement bits for FS/HS
+
+If a device frequently NAKs, it can exhaust the scheduled handshakes in
+a frame. It will then not get polled by the controller until the next
+frame interval. This is most noticeable on FS devices as the controller
+schedules a small set of transactions only once per full-speed frame.
+
+Setting the ENH_PER_NAK_FS/LS bits in the GUCTL1 register increases the
+number of transactions that can be scheduled to Async (Control/Bulk)
+endpoints in the respective frame time. In the FS case, this only
+applies to FS devices directly connected to root ports.

+Subject: [PATCH 527/697] drivers: usb: xhci: prevent a theoretical race on
+ non-coherent platforms
+
+For platforms that have xHCI controllers attached over PCIe, and
+non-coherent routes to main memory, a theoretical race exists between
+posting new TRBs to a ring, and writing to the doorbell register.
+
+In a contended system, write traffic from the CPU may be stalled before
+the memory controller, whereas the CPU to Endpoint route is separate
+and not likely to be contended. Similarly, the DMA route from the
+endpoint to main memory may be separate and uncontended.
+
+Therefore the xHCI can receive a doorbell write and find a stale view
+of a transfer ring. In cases where only a single TRB is ping-ponged at
+a time, this can cause the endpoint to not get polled at all.
+
+Adding a readl() before the write forces a round-trip transaction
+across PCIe, definitively serialising the CPU along the PCI
+producer-consumer ordering rules.

+Subject: [PATCH 528/697] iio: humidity: dht11: Allow non-zero decimals
+
+The DHT11 datasheet is pretty cryptic, but it does suggest that after
+each integer value (humidity and temperature) there are "decimal"
+values. Validate these as integers in the range 0-9 and treat them as
+tenths of a unit.

+Subject: [PATCH 529/697] drm: Set non-desktop property to true for writeback
+ and virtual connectors
+
+The non-desktop property "Indicates the output should be ignored for
+purposes of displaying a standard desktop environment or console."
+
+That sounds like it should be true for all writeback and virtual
+connectors as you shouldn't render a desktop to them, so set it
+by default.

+
+SPI transfers are of defined length, unlike some UART traffic, so it is
+safe to let the DMA controller choose a suitable memory width.

+Subject: [PATCH 536/697] drivers: usb: xhci: set HID bit in streaming endpoint
+ contexts
+
+The xHC may commence Host Initiated Data Moves for streaming endpoints -
+see USB3.2 spec s8.12.1.4.2.4. However, this behaviour is typically
+counterproductive as the submission of UAS URBs in {Status, Data,
+Command} order and 1 outstanding IO per stream ID means the device never
+enters Move Data after a HIMD for Status or Data stages with the same
+stream ID. For OUT transfers this is especially inefficient as the host
+will start transmitting multiple bulk packets as a burst, all of which
+get NAKed by the device - wasting bandwidth.
+
+Also, some buggy UAS adapters don't properly handle the EP flow control
+state this creates - e.g. RTL9210.
+
+Set Host Initiated Data Move Disable to always defer stream selection to
+the device. xHC implementations may treat this field as "don't care,
+forced to 1" anyway - xHCI 1.2 s4.12.1.

+
+The default link frequency of 450MHz has been noted to interfere

+Add the option for 453 and 456MHz to move the signal slightly out

+The documentation isn't very clear explaining how to enable SPI CS

+
+If autonomous speed negotiation is unreliable then brcm_pcie_set_gen()
+can be used to override/limit this behaviour. However, setting the limit
+after the linkup poll means the link can temporarily enter a bad speed
+which may result in link failure. Move the speed setup to just prior to
+releasing perst_n.

+
+Initialise the state max_bpc and requested_max_bpc to the

+Subject: [PATCH 563/697] drm: vc4: dsi: Handle the different command FIFO
+ widths
+
+DSI0 and DSI1 have different widths for the command FIFO (24bit
+vs 32bit), but the driver was assuming the 32bit width of DSI1
+in all cases.
+DSI0 also wants the data packed as 24bit big endian, so the
+formatting code needs updating.
+
+Handle the difference via the variant structure.

+Subject: [PATCH 564/697] dts: bcm2712-rpi: For CM5IO, i2c_csi_dsi needs to be
+ CAM/DISP1
+
+Noted setting up a display on CM5IO. Add
+"dtoverlay=vc4-kms-dsi-ili7881-7inch" fails as it tries to
+find the regulator/backlight/touch on i2c_csi_dsi, which pointed
+at i2c_csi_dsi0 by default.
+
+Adding the dsi0 override updated to point at dsi0, and pointed
+the i2c at i2c_csi_dsi0, which all works.
+
+The default with i2c_csi_dsi needs to be consistent in using
+dsi1/csi1 and the corresponding i2c interface (i2c_csi_dsi1).

+
+Although VBUS_EN on GPIO42 appears on the CM5's 100-way headers,
+USB_OC_N on GPIO43 does not. Remove the signal name to avoid further
+confusion and disappointment.

+ flag
+
+The clock setup had been copied from clk-bcm2835 which had to cope
+with the firmware having configured clocks, so there were flags
+of CLK_IS_CRITICAL and CLK_IGNORE_UNUSED dotted around.
+
+That isn't the situation with RP1 where only the main PLLs, CLK_SYS,
+and CLK_SLOW_SYS are critical, so update the configuration to match.

+Subject: [PATCH 578/697] dts: bcm2712-ds: Restore gpio-direct to gio_aon
+
+gpio-direct mode is a modification of the brcmstb GPIO driver that
+makes it play nicely with the userspace pinctrl utility. The mode
+forces the drive to read its state from the hardware each time, rather
+than relying on cached state. Doing so slightly reduces performance,
+but this is not a heavily used code path.

+
+When the margins are changed, the dlist needs to be regenerated

+
+Setting the zpos_changed flag is sufficient to trigger that

+
+Support displaying DRM_FORMAT_YUV444 and DRM_FORMAT_YVU444 formats.
+Tested with kmstest and kodi. e.g.
+
+kmstest -r 1920x1080@60 -f 400x300-YU24
+
+Note: without the shift of width, only half the chroma is fetched,
+resulting in correct left half of image and corrupt colours on right half.
+
+The increase in width shouldn't affect fetching of Y data,
+as the hardware will clamp at dest width.

+Subject: [PATCH 585/697] drm/vc4: hvs: Print error if we fail an allocation
+
+We need to allocate a few additional structures when checking our
+atomic_state, especially related to hardware SRAM that will hold the
+plane descriptors (DLIST) and the current line context (LBM) during
+composition.
+
+Since those allocation can fail, let's add some error message in that
+case to help debug what goes wrong.

+Subject: [PATCH 590/697] drm/vc4: hvs: Remove ABORT_ON_EMPTY flag
+
+ABORT_ON_EMPTY chooses whether the HVS abandons the current frame
+when it experiences an underflow, or attempts to continue.
+
+In theory the frame should be black from the point of underflow,
+compared to a shift of sebsequent pixels to the left.
+
+Unfortunately it seems to put the HVS is a bad state where it is not
+possible to recover simply. This typically requires a reboot
+following the 'flip done timed out message'.
+
+Discussion with Broadcom has suggested we don't use this flag.
+All their testing is done with it disabled.
+
+Additionally setting BLANK_INSERT_EN causes the HDMI to output
+blank pixels on an underflow which avoids it losing sync.
+
+After this change a 'flip done timed out' due to sdram bandwidth
+starvation or too low a clock is recoverable once the situation improves.

+Since we'll support BCM2712 soon, let's move the logic behind
+vc4_hvs_get_fifo_from_output() to a switch to extend it more easily.

+Subject: [PATCH 595/697] drm/vc4: hvs: Rename hvs_regs list
+
+The HVS register set has been heavily modified in the BCM2712, and we'll
+thus need a separate debugfs_reg32 array for it.
+
+The name hvs_regs is thus a bit too generic, so let's rename it to
+something more specific.

+Subject: [PATCH 596/697] drm/vc4: plane: Change ptr0_offset to an array
+
+The BCM2712 will have a fairly different dlist, that will feature one
+Pointer 0 word for each plane.
+
+Let's prepare by changing the ptr0_offset variable that holds the offset
+in a dlist of the pointer 0 word to an array.

+Subject: [PATCH 597/697] drm/vc4: hvs: Rework LBM alignment
+
+With the introduction of the support for BCM2712, the check of whether
+we're running on vc5 or not to compute the LBM alignment requirement
+doesn't work anymore.
+
+Moreover, the LBM size will need to be computed in words for the
+BCM2712, while we've had sizes in bytes so far.
+
+Aligning on either 64 or 32 words is thus fairly harmful on BCM2712, so
+let's just explicitly align the size when needed, and then call
+drm_mm_insert_node_generic() with an alignment of 1.

+Subject: [PATCH 598/697] drm/vc4: hvs: Change prototype of __vc4_hvs_alloc to
+ pass registers
+
+The BCM2712 HVS has registers to report the size of the various SRAM the
+driver uses, and their size actually differ depending on the stepping.
+
+The initialisation of the memory pools happen in the __vc4_hvs_alloc()
+function that also allocates the main HVS structure, that will then hold
+the pointer to the memory mapping of the registers.
+
+This creates some kind of circular dependency that we can break by
+passing the mapping pointer as an argument for __vc4_hvs_alloc() to use
+to query to get the SRAM sizes and initialise the memory pools
+accordingly.

+
+The offset fields in vc4_plane_state are described as being
+the offset for each buffer in the bo, however it is used to
+store the complete DMA address that is then written into the
+register.
+
+The DMA address including the fb ofset can be retrieved
+using drm_fb_dma_get_gem_addr, and the offset adjustment due to
+clipping is local to vc4_plane_mode_set.
+Drop the offset field from the state, and compute the complete
+DMA address in vc4_plane_mode_set.

+Subject: [PATCH 600/697] drm/vc4: hvs: Enable SCALER_CONTROL early in HVS init
+
+Always enable SCALER_CONTROL before attempting other HVS
+operations. It's safe to write to some parts of the HVS but
+in general it's dangerous to do this because it can cause bus
+lockups.

+
+The HVS found in the BCM2712, while having a similar role, is very
+different from the one found in the previous SoCs. Indeed, the register
+layout is fairly different, and the DLIST format is new as well.
+
+Let's introduce the needed functions to support the new HVS.
+
+This commit adds the C-step register layout. The D-step will be
+added later.

+Subject: [PATCH 606/697] drm/vc4: crtc: Add support for BCM2712 PixelValves
+
+The PixelValves found on the BCM2712 are similar to the ones found in
+the previous generation.
+
+Compared to BCM2711:
+- the pixelvalves only drive one HDMI controller each
+- HDMI1 PixelValve has a FIFO long enough to support 4k at 60Hz
+- support has been added for odd horizontal timings whilst at 2pixels/clock

+ controllers
+
+The HDMI controllers found in the BCM2712 are largely the ones found in
+the BCM2711 with a different PHY.
+
+There's some difference with how timings are split between registers,
+and HDMI1 is now able to run at 4k/60Hz.

+Subject: [PATCH 613/697] drm/vc4: txp: Move the encoder type in the variant
+ structure
+
+We'll have multiple TXP instances in the BCM2712, so we can't use a
+single encoder type anymore. Let's tie the encoder type to the
+compatible.

+Subject: [PATCH 615/697] drm/vc4: txp: Add support for BCM2712 MOP
+
+The BCM2712 has an evolution of what used to be called TXP in the
+earlier SoCs, but is now called MOP.
+
+There's a few differences still, so we can add a new compatible to deal
+with them easily.

+Subject: [PATCH 622/697] drm/vc4: Enable bg_fill if there are no planes
+ enabled
+
+The default was to have enable_bg_fill disabled and the first
+plane set it if it wasn't opaque and covering the whole screen.
+However that meant that if no planes were enabled, then the
+background fill wasn't enabled, and would give a striped
+output from the uninitialised output buffer.
+
+Initialise it to enabled to avoid this.

+Subject: [PATCH 623/697] drm/vc4: Drop planes that are completely off-screen
+ or 0 crtc size
+
+It is permitted for a plane to be configured such that none
+of it is on-screen via either negative dest rectangle X,Y
+offset, or an offset that is greater than the crtc dimensions.
+
+These planes were resized via drm_atomic_helper_check_plane_state
+such that the source rectangle had a zero width or height, but
+they still created a dlist entry even though they contributed
+no pixels. In the case of vc6_plane_mode_set, that it could result
+in negative values being written into registers, which caused
+incorrect behaviour.
+
+Drop planes that result in a source width or height of 0 pixels
+or an on-screen size of 0 pixels to avoid the incorrect rendering.

+Subject: [PATCH 627/697] arm64: dts: broadcom: Add DT for D-step version of
+ BCM2712
+
+The D-Step has some minor variations in the hardware, so needs
+matching changes to DT.
+
+Add a new DTS file that modifies the existing (C-step) devicetree.

+Subject: [PATCH 632/697] drm/vc4: hvs: Defer dlist slots deallocation
+
+During normal operations, the cursor position update is done through an
+asynchronous plane update, which on the vc4 driver basically just
+modifies the right dlist word to move the plane to the new coordinates.
+
+However, when we have the overscan margins setup, we fall back to a
+regular commit when we are next to the edges. And since that commit
+happens to be on a cursor plane, it's considered a legacy cursor update
+by KMS.
+
+The main difference it makes is that it won't wait for its completion
+(ie, next vblank) before returning. This means if we have multiple
+commits happening in rapid succession, we can have several of them
+happening before the next vblank.
+
+In parallel, our dlist allocation is tied to a CRTC state, and each time
+we do a commit we end up with a new CRTC state, with the previous one
+being freed. This means that we free our previous dlist entry (but don't
+clear it though) every time a new one is being committed.
+
+Now, if we were to have two commits happening before the next vblank, we
+could end up freeing reusing the same dlist entries before the next
+vblank.
+
+Indeed, we would start from an initial state taking, for example, the
+dlist entries 10 to 20, then start a commit taking the entries 20 to 30
+and setting the dlist pointer to 20, and freeing the dlist entries 10 to
+20. However, since we haven't reach vblank yet, the HVS is still using
+the entries 10 to 20.
+
+If we were to make a new commit now, chances are the allocator are going
+to give the 10 to 20 entries back, and we would change their content to
+match the new state. If vblank hasn't happened yet, we just corrupted
+the active dlist entries.
+
+A first attempt to solve this was made by creating an intermediate dlist
+buffer to store the current (ie, as of the last commit) dlist content,
+that we would update each time the HVS is done with a frame. However, if
+the interrupt handler missed the vblank window, we would end up copying
+our intermediate dlist to the hardware one during the composition,
+essentially creating the same issue.
+
+Since making sure that our interrupt handler runs within a fixed,
+constrained, time window would require to make Linux a real-time kernel,
+this seems a bit out of scope.
+
+Instead, we can work around our original issue by keeping the dlist
+slots allocation longer. That way, we won't reuse a dlist slot while
+it's still in flight. In order to achieve this, instead of freeing the
+dlist slot when its associated CRTC state is destroyed, we'll queue it
+in a list.
+
+A naive implementation would free the buffers in that queue when we get
+our end of frame interrupt. However, there's still a race since, just
+like in the shadow dlist case, we don't control when the handler for
+that interrupt is going to run. Thus, we can end up with a commit adding
+an old dlist allocation to our queue during the window between our
+actual interrupt and when our handler will run. And since that buffer is
+still being used for the composition of the current frame, we can't free
+it right away, exposing us to the original bug.
+
+Fortunately for us, the hardware provides a frame counter that is
+increased each time the first line of a frame is being generated.
+Associating the frame counter the image is supposed to go away to the
+allocation, and then only deallocate buffers that have a counter below
+or equal to the one we see when the deallocation code should prevent the
+above race from occurring.

+
+We have a read-modify-write race when updating SCALER_DISPCTRL for
+underrun and end-of-frame interrupts.
+Ideally it would be fixed via a spinlock or similar, but that will
+require a reasonable amount of study to ensure we don't get deadlocks.
+
+The underrun reporting is only for debug, so disable it for now.

+Subject: [PATCH 635/697] drm: vc4: Block swiotlb bounce buffers being imported
+ as dmabuf
+
+The dmabuf import already checks that the backing buffer is contiguous
+and rejects it if it isn't. vc4 also requires that the buffer is
+in the bottom 1GB of RAM, and this is all correctly defined via
+dma-ranges.
+
+However the kernel silently uses swiotlb to bounce dma buffers
+around if they are in the wrong region. This relies on dma sync
+functions to be called in order to copy the data to/from the
+bounce buffer.
+
+DRM is based on all memory allocations being coherent with the
+GPU so that any updates to a framebuffer will be acted on without
+the need for any additional update. This is fairly fundamentally
+incompatible with needing to call dma_sync_ to handle the bounce
+buffer copies, and therefore we have to detect and reject mappings
+that use bounce buffers.

+
+The TC358762 bridge and panel decodes the mode differently on
+DSI0 to DSI1 for no obvious reason, and results in a shift off
+the screen.
+Whilst it would be possible to change the compatible used for
+the panel, that then messes up Pi5.
+
+As it appears to be restricted to vc4 DSI0, fix up the mode
+in vc4_dsi.

+ transfers
+
+The DSI block appears to be able to come up stuck in a condition where
+it leaves the lanes in HS mode or just jabbering. This stops LP
+transfers from completing as there is no LP time available. This is
+signalled via the LP1 contention error.
+
+Enabling video briefly clears that condition, so if we detect the
+error condition, enable video mode and then retry.

+Subject: [PATCH 644/697] drm/vc4: Allow setting the TV norm via module
+ parameter
+
+Similar to the ch7006 and nouveau drivers, introduce a "tv_mode" module
+parameter that allow setting the TV norm by specifying vc4.tv_norm= on
+the kernel command line.
+
+If that is not specified, try inferring one of the most popular norms
+(PAL or NTSC) from the video mode specified on the command line. On
+Raspberry Pis, this causes the most common cases of the sdtv_mode
+setting in config.txt to be respected.
+
+Signed-off-by: Mateusz Kwiatkowski <kfyatek+publicgit@gmail.com>
+
+drm/vc4: Do not reset tv mode as this is already handled by framework
+
+In vc4_vec_connector_reset, the tv mode is already reset to the
+property default by drm_atomic_helper_connector_tv_reset, so there
+is no need for a local fixup to potentially some other default.
+
+Fixes: 96922af14473 ("drm/vc4: Allow setting the TV norm via module parameter")

+Subject: [PATCH 649/697] drm/vc4_hdmi: Allow hotplug detect to be forced
+
+See: https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off
+
+While the kernel provides a :D flag for assuming device is connected,
+it doesn't stop this function from being called and generating a cec_phys_addr_invalidate
+message when hotplug is deasserted.
+
+That message provokes a flurry of CEC messages which for many users results in the TV
+switching back on again and it's very hard to get it to stay switched off.
+
+It seems to only occur with an AVR and TV connected but has been observed across a
+number of manufacturers.
+
+The issue started with https://github.com/raspberrypi/linux/pull/4371
+and this provides an optional way of getting back the old behaviour

+Subject: [PATCH 650/697] vc4/hdmi: Ignore hotplug interrupt with force_hotplug
+
+The intention of the vc4.force_hotplug setting is to
+ignore hotplug completely.
+
+It can be used when a display toggles hotplug when
+switching AV inputs, going into standby or changing a
+KVM switch, and some side effect of that is unwanted.
+
+It turns out while vc4.force_hotplug currently makes
+hotplug always read as asserted, that isn't enough to
+stop drm doing lots of stuff, including re-reading
+the edid.
+
+An example of what drm does with a hotplug deasert/assert
+and vc4.force_hotplug=1 currently is:
+
+https://paste.debian.net/hidden/dc07434b/
+
+That is unwanted. Lets ignore the hotplug interrupt
+completely so drm is blissfully unaware of the hotplug change.

+Subject: [PATCH 651/697] drm/vc4: Add a delay after disabling hdmi phy output
+
+There appears to be a requirement for some devices
+(I'm testing with a 8K VRROOM 40Gbps HDMI switch)
+for a measable delay between removing the hdmi phy output from
+the old mode, to enabling the hdmi phy output for the new mode.
+
+Without the delay, a mode switch has a small change of getting a permanent
+'no signal', which requires a subsequent mode switch or a unplug/replug
+to redetect.
+
+Switching between 4kp24/25/30 modes fails about 5% of time in my testing.
+
+Add a delay to make it impossible to switch faster than this.

+Subject: [PATCH 656/697] drm/vc4: Add support for per plane scaling filter
+ selection
+
+Seeing as the HVS can be configured with regard the scaling filter,
+and DRM now supports selecting scaling filters at a per CRTC or
+per plane level, we can implement it.
+
+Default remains as the Mitchell/Netravali filter, but nearest
+neighbour is now also implemented.

+Subject: [PATCH 657/697] drm/vc4: Use the TPZ scaling filter for 1x1 source
+ images
+
+The documentation says that the TPZ filter can not upscale,
+and requesting a scaling factor > 1:1 will output the original
+image in the top left, and repeat the right/bottom most pixels
+thereafter.
+That fits perfectly with upscaling a 1x1 image which is done
+a fair amount by some compositors to give solid colour, and it
+saves a large amount of LBM (TPZ is based on src size, whilst
+PPF is based on dest size).
+
+Select TPZ filter for images with source rectangle <=1.

+
+The HVS can accept an arbitrary number of planes, provided

+the display list can fit into the dlist memory.
+
+Now that DRM will support 64 planes per device, increase
+the number of overlay planes from 16 to 48 so that the
+dlist complexity can be increased (eg 4x4 video wall on

+Subject: [PATCH 664/697] drm/vc4: Remove request for min clocks when hdmi
+ output is disabled
+
+Currently, booting with no hdmi connected has:
+pi@pi4:~ $ vcgencmd measure_clock hdmi pixel
+frequency(9)=120010256
+frequency(29)=74988280
+
+After connecting hdmi we get:
+pi@pi4:~ $ vcgencmd measure_clock hdmi pixel
+frequency(9)=300005856
+frequency(29)=149989744
+
+and that persists after disconnecting hdmi
+
+I can measure this on a power supply as 10mA@5.2V (52mW).
+
+We should always remove clk_set_min_rate requests
+when we no longer need them.

+Subject: [PATCH 666/697] drm/vc4: fkms: Add firmware-kms mode
+
+This is a squash of all firmware-kms related patches from previous
+branches, up to and including
+"drm/vc4: Set the possible crtcs mask correctly for planes with FKMS"
+plus a couple of minor fixups for the 5.9 branch.
+Please refer to earlier branches for full history.
+
+This patch includes work by Eric Anholt, James Hughes, Phil Elwell,
+Dave Stevenson, Dom Cobley, and Jonathon Bell.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/vc4: Fixup firmware-kms after "drm/atomic: Pass the full state to CRTC atomic enable/disable"
+
+Prototype for those calls changed, so amend fkms (which isn't
+upstream) to match.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/vc4: Fixup fkms for API change
+
+Atomic flush and check changed API, so fix up the downstream-only
+FKMS driver.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/vc4: Make normalize_zpos conditional on using fkms
+
+Eric's view was that there was no point in having zpos
+support on vc4 as all the planes had the same functionality.
+
+Can be later squashed into (and fixes):
+drm/vc4: Add firmware-kms mode
+
+Signed-off-by: Dom Cobley <popcornmix@gmail.com>
+
+drm/vc4: FKMS: Change of Broadcast RGB mode needs a mode change
+
+The Broadcast RGB (aka HDMI limited/full range) property is only
+notified to the firmware on mode change, so this needs to be
+signalled when set.

+vc4/drv: Only notify firmware of display done with kms
+
+fkms driver still wants firmware display to be active
+
+Signed-off-by: Dom Cobley <popcornmix@gmail.com>
+
+ydrm/vc4: fkms: Fix margin calculations for the right/bottom edges
+
+The calculations clipped the right/bottom edge of the clipped
+range based on the left/top margins.

+drm/vc4: fkms: Use new devm_rpi_firmware_get api
+
+drm/kms: Add allow_fb_modifiers
+
+Signed-off-by: Dom Cobley <popcornmix@gmail.com>
+
+drm/vc4: Add async update support for cursor planes
+
+Now that cursors are implemented as regular planes, all cursor
+movements result in atomic updates. As the firmware-kms driver
+doesn't support asynchronous updates, these are synchronous, which
+limits the update rate to the screen refresh rate. Xorg seems unaware
+of this (or at least of the effect of this), because if the mouse is
+configured with a higher update rate than the screen then continuous
+mouse movement results in an increasing backlog of mouse events -
+cue extreme lag.
+
+Add minimal support for asynchronous updates - limited to cursor
+planes - to eliminate the lag.
+

+drivers/gpu/drm/vc4: Add missing 32-bit RGB formats
+
+The missing 32-bit per pixel ABGR and various "RGB with an X value"
+formats are added. Change sent by Dave Stevenson.

+
+drm: vc4: Fixup duplicated macro definition in vc4_firmware_kms
+
+Both vc4_drv.h and vc4_firmware_kms.c had definitions for
+to_vc4_crtc.
+
+Rename the fkms one to make it unique, and drop the magic
+define vc4_crtc vc4_kms_crtc
+define to_vc4_crtc to_vc4_kms_crtc
+that renamed half the variable and function names in a slightly
+unexpected way.
+

+
+drm/vc4: Fix FKMS for when the YUV chroma planes are different buffers
+
+The code was assuming that it was a single buffer with offsets,
+when kmstest uses separate buffers and 0 offsets for each plane.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/vc4: fkms: Rename plane related functions
+
+The name collide with the Full KMS functions that are going to be made
+public.

+
+drm/vc4_fkms: Fix up interrupt handler for both 2835/2711 and 2712
+
+2712 has switched from using the SMI peripheral to another interrupt
+source for the vsync interrupt, so handle both sources cleanly.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+drm/vc4: fkms: No SMI abuse needed on BCM2712
+
+Since we don't use the (absent) SMI block to create interrupts on
+BCM2712, there's no need to map any registers.

+ vc4_find_crtc_for_encoder
+
+The DRM device pointer and the DRM encoder pointer are redundant, since
+the latter is attached to the former and we can just follow the
+drm_encoder->dev pointer.
+
+Let's remove the drm_device pointer argument.

+Subject: [PATCH 669/697] drm/vc4: tests: Return the allocated output
+
+Some tests will need to retrieve the output that was just allocated by
+vc4_mock_atomic_add_output().
+
+Instead of making them look them up in the DRM device, we can simply
+make vc4_mock_atomic_add_output() return an error pointer that holds the
+allocated output instead of the error code.

+Subject: [PATCH 670/697] drm/vc4: tests: Add BCM2712 mock driver
+
+The BCM2712 has a simpler pipeline that can only output to a writeback
+connector and two HDMI controllers.
+
+Let's allow our kunit tests to create a mock of that pipeline.

+
+The current mock planes were just using the regular drm_plane_state,
+while the driver expect struct vc4_plane_state that subclasses
+drm_plane_state.
+
+Hook the proper implementations of reset, duplicate_state, destroy and
+atomic_check to create vc4_plane_state.

+a helper to add a plane to an existing atomic state.

+
+The BCM2712 comes with a different LBM size computation than the

+Subject: [PATCH 678/697] drm/vc4: Cache LBM allocations to avoid
+ double-buffering
+
+LBM is only relevant for each active dlist, so there is
+no need to double-buffer the allocations.
+
+Cache the allocations per plane so that we can ensure the
+allocations are possible.

+Subject: [PATCH 683/697] serial: tty: Add a driver for the RPi firmware UART
+
+On Raspberry Pi 4 and earlier models the firmware provides
+a low speed (up to 115200 baud) bit-bashed UART on arbitrary
+GPIOs using the second VPU core.
+
+The firmware driver is designed to support 19200 baud. Higher
+rates up to 115200 seem to work but there may be more jitter.
+
+This can be useful for debug or managing additional low
+speed peripherals if the hardware PL011 and 8250 hardware
+UARTs are already used for console / bluetooth.
+
+The firmware driver requires a fixed core clock frequency
+and also requires the VPU PWM audio driver to be disabled
+(dtparam=audio=off)
+
+Runtime configuration is handled via the vc-mailbox APIs
+with the FIFO buffers being allocated in uncached VPU
+addressable memory. The FIFO pointers are stored in spare
+VideoCore multi-core sync registers in order to reduce the number
+of uncached SDRAM accesses thereby reducing jitter.

+Subject: [PATCH 686/697] ARM: dts: Remove duplicate tags
+
+A dts file should have exactly one /dts-v1/ tag, and overlays should
+also have one /plugin/ tag. Through careless inclusion of other files,
+some Device Trees and overlays end up with duplicated tags - this
+commit removes them.
+
+The change is largely cosmetic, unless using an old version of dtc.

+
+Some NVME drives seem to request significant amounts of DMA coherent
+memory - enough to exhaust our standard 64MB CMA allocation.
+
+Try disabling the feature to see what effect it has - drives should
+continue to function without it.

+Subject: [PATCH 695/697] cgroup: Add cgroup_enable option
+
+The upstream addition of the kernel parameter cgroup_disable makes it
+possible to configure cgroups at boot time. In theory, re-enabling a
+disabled cgroup is simply a case of removing the relevant cgroup_disable
+setting, but this is difficult if the setting comes from Device Tree.
+
+Re-introduce cgroup_enable as a way around the problem.

+Subject: [PATCH 697/697] drm/v3d: Correct clock settng calls to new APIs
+
+There was a report that 6.12 kernel has lower benchmark
+scores than 6.6.
+
+I can confirm, and found it started with 6.8 kernel
+which moved some code into a new file (v3d_submit.c)
+and in two places the change to the clock api were missed.
+
+The effect of the bug is the v3d clock sometimes
+unwantedly drops to a lower rate.
+
+With this patch the benchmark scores are good again.
+

+Subject: [PATCH 3/5] block: introduce add_disk_fwnode()
+
+Introduce add_disk_fwnode() as a replacement of device_add_disk() that
+permits to pass and attach a fwnode to disk dev.
+
+This variant can be useful for eMMC that might have the partition table
+for the disk defined in DT. A parser can later make use of the attached
+fwnode to parse the related table and init the hardcoded partition for
+the disk.
+
+device_add_disk() is converted to a simple wrapper of add_disk_fwnode()
+with the fwnode entry set as NULL.

+Subject: [PATCH 5/5] block: add support for partition table defined in OF
+
+Add support for partition table defined in Device Tree. Similar to how
+it's done with MTD, add support for defining a fixed partition table in
+device tree.
+
+A common scenario for this is fixed block (eMMC) embedded devices that
+have no MBR or GPT partition table to save storage space. Bootloader
+access the block device with absolute address of data.
+
+This is to complete the functionality with an equivalent implementation
+with providing partition table with bootargs, for case where the booargs
+can't be modified and tweaking the Device Tree is the only solution to
+have an usabe partition table.
+
+The implementation follow the fixed-partitions parser used on MTD
+devices where a "partitions" node is expected to be declared with
+"fixed-partitions" compatible in the OF node of the disk device
+(mmc-card for eMMC for example) and each child node declare a label
+and a reg with offset and size. If label is not declared, the node name
+is used as fallback. Eventually is also possible to declare the read-only
+property to flag the partition as read-only.

+
+Now that we have b9c7ac4fe22c ("r8169: disable ALDPS per default for
+RTL8125"), the first attempt to fix the issue shouldn't be needed
+any longer. So let's effectively revert 621735f59064 ("r8169: fix
+rare issue with broken rx after link-down on RTL8125") and see
+whether anybody complains.

+Subject: [PATCH] r8169: enable SG/TSO on selected chip versions per default
+
+Due to problem reports in the past SG and TSO/TSO6 are disabled per
+default. It's not fully clear which chip versions are affected, so we
+may impact also users of unaffected chip versions, unless they know
+how to use ethtool for enabling SG/TSO/TSO6.
+Vendor drivers r8168/r8125 enable SG/TSO/TSO6 for selected chip
+versions per default, I'd interpret this as confirmation that these
+chip versions are unaffected. So let's do the same here.

+Subject: [PATCH] r8169: don't take RTNL lock in rtl_task()
+
+There's not really a benefit here in taking the RTNL lock. The task
+handler does exception handling only, so we're in trouble anyway when
+we come here, and there's no need to protect against e.g. a parallel
+ethtool call.
+A benefit of removing the RTNL lock here is that we now can
+synchronously cancel the workqueue from a context holding the RTNL mutex.

+
+In case of a problem with firmware loading we inform at the driver level,

+switch to firmware_request_nowarn() to avoid duplicated error messages.
+In addition switch to warn level because the firmware is optional and

+Subject: [PATCH] r8169: enable EEE at 2.5G per default on RTL8125B
+
+Register a6d/12 is shadowing register MDIO_AN_EEE_ADV2. So this line
+disables advertisement of EEE at 2.5G. Latest vendor driver r8125
+doesn't do this (any longer?), so this mode seems to be safe.
+EEE saves quite some energy, therefore enable this mode per default.

+Subject: [PATCH] r8169: copy vendor driver 2.5G/5G EEE advertisement
+ constraints
+
+Vendor driver r8125 doesn't advertise 2.5G EEE on RTL8125A, and r8126
+doesn't advertise 5G EEE. Likely there are compatibility issues,
+therefore do the same in r8169.
+With this change we don't have to disable 2.5G EEE advertisement in
+rtl8125a_config_eee_phy() any longer.
+We use new phylib accessor phy_set_eee_broken() to mark the respective
+EEE modes as broken.

+Subject: [PATCH] net: phy: realtek: merge the drivers for internal NBase-T
+ PHY's
+
+The Realtek RTL8125/RTL8126 NBase-T MAC/PHY chips have internal PHY's
+which are register-compatible, at least for the registers we use here.
+So let's use just one PHY driver to support all of them.
+These internal PHY's exist also as external C45 PHY's, but on the
+internal PHY's no access to MMD registers is possible. This can be
+used to differentiate between the internal and external version.
+
+As a side effect the drivers for two now external-only drivers don't
+require read_mmd/write_mmd hooks any longer.

+Subject: [PATCH] net: phy: realtek: add RTL8125D-internal PHY
+
+The first boards show up with Realtek's RTL8125D. This MAC/PHY chip
+comes with an integrated 2.5Gbps PHY with ID 0x001cc841. It's not
+clear yet whether there's an external version of this PHY and how
+Realtek calls it, therefore use the numeric id for now.

+Subject: [PATCH] net: phy: realtek: HWMON support for standalone versions of
+ RTL8221B and RTL8251
+
+HWMON support has been added for the RTL8221/8251 PHYs integrated together
+with the MAC inside the RTL8125/8126 chips. This patch extends temperature
+reading support for standalone variants of the mentioned PHYs.
+
+I don't know whether the earlier revisions of the RTL8226 also have a
+built-in temperature sensor, so they have been skipped for now.
+
+Tested on RTL8221B-VB-CG.

+Subject: [PATCH] net: phy: aquantia: allow forcing order of MDI pairs
+
+Despite supporting Auto MDI-X, it looks like Aquantia only supports
+swapping pair (1,2) with pair (3,6) like it used to be for MDI-X on
+100MBit/s networks.
+
+When all 4 pairs are in use (for 1000MBit/s or faster) the link does not
+come up with pair order is not configured correctly, either using
+MDI_CFG pin or using the "PMA Receive Reserved Vendor Provisioning 1"
+register.
+
+Normally, the order of MDI pairs being either ABCD or DCBA is configured
+by pulling the MDI_CFG pin.
+
+However, some hardware designs require overriding the value configured
+by that bootstrap pin. The PHY allows doing that by setting a bit in
+"PMA Receive Reserved Vendor Provisioning 1" register which allows
+ignoring the state of the MDI_CFG pin and another bit configuring
+whether the order of MDI pairs should be normal (ABCD) or reverse
+(DCBA). Pair polarity is not affected and remains identical in both
+settings.
+
+Introduce property "marvell,mdi-cfg-order" which allows forcing either
+normal or reverse order of the MDI pairs from DT.
+
+If the property isn't present, the behavior is unchanged and MDI pair
+order configuration is untouched (ie. either the result of MDI_CFG pin
+pull-up/pull-down, or pair order override already configured by the
+bootloader before Linux is started).
+
+Forcing normal pair order is required on the Adtran SDG-8733A Wi-Fi 7
+residential gateway.

+
+Use newly defined 'active-high' property to set the
+VEND1_GLOBAL_LED_DRIVE_VDD bit and let 'active-low' clear that bit. This
+reflects the technical reality which was inverted in the previous
+description in which the 'active-low' property was used to actually set
+the VEND1_GLOBAL_LED_DRIVE_VDD bit, which means that VDD (ie. supply
+voltage) of the LED is driven rather than GND.

+Add basic support for LEDs connected to MaxLinear GPY2xx and GPY115 PHYs.
+The PHYs allow up to 4 LEDs to be connected.
+Implement controlling LEDs in software as well as netdev trigger offloading
+and LED polarity setup.
+
+The hardware claims to support 16 PWM brightness levels but there is no
+documentation on how to use that feature, hence this is not supported.

+
+According the datasheet covering the LED (0x1b) register:
+0B Active High LEDx pin driven high when activated
+1B Active Low LEDx pin driven low when activated
+
+Make use of the now available 'active-high' property and correctly
+reflect the polarity setting which was previously inverted.

+Subject: [PATCH 4/4] net: phy: intel-xway: add support for PHY LEDs
+
+The intel-xway PHY driver predates the PHY LED framework and currently
+initializes all LED pins to equal default values.
+
+Add PHY LED functions to the drivers and don't set default values if
+LEDs are defined in device tree.
+
+According the datasheets 3 LEDs are supported on all Intel XWAY PHYs.

+Subject: [PATCH] gpio: regmap: Use generic request/free ops
+
+Set the gpiochip request and free ops to the generic implementations.
+This way a user can provide a gpio-ranges property defined for a pinmux,
+easing muxing of gpio functions. Provided that the pin controller
+implementents the pinmux op .gpio_request_enable(), pins will
+automatically be muxed to their GPIO function when requested.

+Subject: [PATCH] net: dsa: mv88e6xxx: Support LED control
+
+This adds control over the hardware LEDs in the Marvell
+MV88E6xxx DSA switch and enables it for MV88E6352.
+
+This fixes an imminent problem on the Inteno XG6846 which
+has a WAN LED that simply do not work with hardware
+defaults: driver amendment is necessary.
+
+The patch is modeled after Christian Marangis LED support
+code for the QCA8k DSA switch, I got help with the register
+definitions from Tim Harvey.
+
+After this patch it is possible to activate hardware link
+indication like this (or with a similar script):
+
+  cd /sys/class/leds/Marvell\ 88E6352:05:00:green:wan/
+  echo netdev > trigger
+  echo 1 > link
+
+This makes the green link indicator come up on any link
+speed. It is also possible to be more elaborate, like this:
+
+  cd /sys/class/leds/Marvell\ 88E6352:05:00:green:wan/
+  echo netdev > trigger
+  echo 1 > link_1000
+  cd /sys/class/leds/Marvell\ 88E6352:05:01:amber:wan/
+  echo netdev > trigger
+  echo 1 > link_100
+
+Making the green LED come on for a gigabit link and the
+amber LED come on for a 100 mbit link.
+
+Each port has 2 LED slots (the hardware may use just one or
+none) and the hardware triggers are specified in four bits per
+LED, and some of the hardware triggers are only available on the
+SFP (fiber) uplink. The restrictions are described in the
+port.h header file where the registers are described. For
+example, selector 1 set for LED 1 on port 5 or 6 will indicate
+Fiber 1000 (gigabit) and activity with a blinking LED, but
+ONLY for an SFP connection. If port 5/6 is used with something
+not SFP, this selector is a noop: something else need to be
+selected.
+
+After the previous series rewriting the MV88E6xxx DT
+bindings to use YAML a "leds" subnode is already valid
+for each port, in my scratch device tree it looks like
+this:
+
+   leds {
+     #address-cells = <1>;
+     #size-cells = <0>;
+
+     led@0 {
+       reg = <0>;
+       color = <LED_COLOR_ID_GREEN>;
+       function = LED_FUNCTION_LAN;
+       default-state = "off";
+       linux,default-trigger = "netdev";
+     };
+     led@1 {
+       reg = <1>;
+       color = <LED_COLOR_ID_AMBER>;
+       function = LED_FUNCTION_LAN;
+       default-state = "off";
+     };
+   };
+
+This DT config is not yet configuring everything: when the netdev
+default trigger is assigned the hw acceleration callbacks are
+not called, and there is no way to set the netdev sub-trigger
+type (such as link_1000) from the device tree, such as if you want
+a gigabit link indicator. This has to be done from userspace at
+this point.
+
+We add LED operations to all switches in the 6352 family:
+6172, 6176, 6240 and 6352.

+ADM6996FC / ADM6996M switch chip driver
+
+
+1. General information
+
+  This driver supports the FC and M models only. The ADM6996F and L are
+  completely different chips.
+  
+  Support for the FC model is extremely limited at the moment. There is no VLAN
+  support as of yet. The driver will not offer an swconfig interface for the FC
+  chip.
+ 
+1.1 VLAN IDs
+
+  It is possible to define 16 different VLANs. Every VLAN has an identifier, its
+  VLAN ID. It is easiest if you use at most VLAN IDs 0-15. In that case, the
+  swconfig based configuration is very straightforward. To define two VLANs with
+  IDs 4 and 5, you can invoke, for example:
+  
+      # swconfig dev ethX vlan 4 set ports '0 1t 2 5t' 
+      # swconfig dev ethX vlan 5 set ports '0t 1t 5t'
+  
+  The swconfig framework will automatically invoke 'port Y set pvid Z' for every
+  port that is an untagged member of VLAN Y, setting its Primary VLAN ID. In
+  this example, ports 0 and 2 would get "pvid 4". The Primary VLAN ID of a port
+  is the VLAN ID associated with untagged packets coming in on that port.
+  
+  But if you wish to use VLAN IDs outside the range 0-15, this automatic
+  behaviour of the swconfig framework becomes a problem. The 16 VLANs that
+  swconfig can configure on the ADM6996 also have a "vid" setting. By default,
+  this is the same as the number of the VLAN entry, to make the simple behaviour
+  above possible. To still support a VLAN with a VLAN ID higher than 15
+  (presumably because you are in a network where such VLAN IDs are already in
+  use), you can change the "vid" setting of the VLAN to anything in the range
+  0-1023. But suppose you did the following:
+  
+      # swconfig dev ethX vlan 0 set vid 998 
+      # swconfig dev ethX vlan 0 set ports '0 2 5t'
+ 
+  Now the swconfig framework will issue 'port 0 set pvid 0' and 'port 2 set pvid
+  0'. But the "pvid" should be set to 998, so you are responsible for manually
+  fixing this!
+
+1.2 VLAN filtering
+
+  The switch is configured to apply source port filtering. This means that
+  packets are only accepted when the port the packets came in on is a member of
+  the VLAN the packet should go to.
+
+  Only membership of a VLAN is tested, it does not matter whether it is a tagged
+  or untagged membership.
+
+  For untagged packets, the destination VLAN is the Primary VLAN ID of the
+  incoming port. So if the PVID of a port is 0, but that port is not a member of
+  the VLAN with ID 0, this means that untagged packets on that port are dropped.
+  This can be used as a roundabout way of dropping untagged packets from a port,
+  a mode often referred to as "Admit only tagged packets".
+
+1.3 Reset
+
+  The two supported chip models do not have a sofware-initiated reset. When the
+  driver is initialised, as well as when the 'reset' swconfig option is invoked,
+  the driver will set those registers it knows about and supports to the correct
+  default value. But there are a lot of registers in the chip that the driver
+  does not support. If something changed those registers, invoking 'reset' or
+  performing a warm reboot might still leave the chip in a "broken" state. Only
+  a hardware reset will bring it back in the default state.
+
+2. Technical details on PHYs and the ADM6996
+
+  From the viewpoint of the Linux kernel, it is common that an Ethernet adapter
+  can be seen as a separate MAC entity and a separate PHY entity. The PHY entity
+  can be queried and set through registers accessible via an MDIO bus. A PHY
+  normally has a single address on that bus, in the range 0 through 31.
+
+  The ADM6996 has special-purpose registers in the range of PHYs 0 through 10.
+  Even though all these registers control a single ADM6996 chip, the Linux
+  kernel treats this as 11 separate PHYs.  The driver will bind to these
+  addresses to prevent a different PHY driver from binding and corrupting these
+  registers.
+
+  What Linux sees as the PHY on address 0 is meant for the Ethernet MAC
+  connected to the CPU port of the ADM6996 switch chip (port 5). This is the
+  Ethernet MAC you will use to send and receive data through the switch.
+
+  The PHYs at addresses 16 through 20 map to the PHYs on ports 0 through 4 of
+  the switch chip. These can be accessed with the Generic PHY driver, as the
+  registers have the common layout.
+
+  If a second Ethernet MAC on your board is wired to the port 4 PHY, that MAC
+  needs to bind to PHY address 20 for the port to work correctly.
+
+  The ADM6996 switch driver will reset the ports 0 through 3 on startup and when
+  'reset' is invoked. This could clash with a different PHY driver if the kernel
+  binds a PHY driver to address 16 through 19.
+
+  If Linux binds a PHY on addresses 1 through 10 to an Ethernet MAC, the ADM6996
+  driver will simply always report a connected 100 Mbit/s full-duplex link for
+  that PHY, and provide no other functionality. This is most likely not what you
+  want. So if you see a message in your log
+
+  	ethX: PHY overlaps ADM6996, providing fixed PHY yy.
+
+  This is most likely an indication that ethX will not work properly, and your
+  kernel needs to be configured to attach a different PHY to that Ethernet MAC.
+
+  Controlling the mapping between MACs and PHYs is usually done in platform- or
+  board-specific fixup code. The ADM6996 driver has no influence over this.

+ *
+ * This program is free software; you can redistribute it and/or modify it

+ * by the Free Software Foundation.
+ *
+ * This parser builds from the "fixed-partitions" one (see ofpart.c), but it can
+ * handle dynamic partitions as found on routerboot devices.
+ *
+ * DTS nodes are defined as follows:
+ * For fixed partitions:
+ *	node-name@unit-address {
+ *		reg = <prop-encoded-array>;
+ *		label = <string>;
+ *		read-only;
+ *		lock;
+ *	};
+ *
+ * reg property is mandatory; other properties are optional.
+ * reg format is <address length>. length can be 0 if the next partition is
+ * another fixed partition or a "well-known" partition as defined below: in that
+ * case the partition will extend up to the next one.
+ *
+ * For dynamic partitions:
+ *	node-name {
+ *		size = <prop-encoded-array>;
+ *		label = <string>;
+ *		read-only;
+ *		lock;
+ *	};
+ *
+ * size property is normally mandatory. It can only be omitted (or set to 0) if:
+ *	- the partition is a "well-known" one (as defined below), in which case
+ *	  the partition size will be automatically adjusted; or
+ *	- the next partition is a fixed one or a "well-known" one, in which case
+ *	  the current partition will extend up to the next one.
+ * Other properties are optional.
+ * size format is <length>.
+ * By default dynamic partitions are appended after the preceding one, except
+ * for "well-known" ones which are automatically located on flash.
+ *
+ * Well-known partitions (matched via label or node-name):
+ * - "hard_config"
+ * - "soft_config"
+ * - "dtb_config"
+ *
+ * Note: this parser will happily register 0-sized partitions if misused.
+ *
+ * This parser requires the DTS to list partitions in ascending order as
+ * expected on the MTD device.
+ *
+ * Since only the "hard_config" and "soft_config" partitions are used in OpenWRT,
+ * a minimal working DTS could define only these two partitions dynamically (in
+ * the right order, usually hard_config then soft_config).
+ *
+ * Note: some mips RB devices encode the hard_config offset and length in two
+ * consecutive u32 located at offset 0x14 (for ramips) or 0x24 (for ath79) on
+ * the SPI NOR flash. Unfortunately this seems inconsistent across machines and
+ * does not apply to e.g. ipq-based ones, so we ignore that information.
+ *
+ * Note: To find well-known partitions, this parser will go through the entire
+ * top mtd partition parsed, _before_ the DTS nodes are processed. This works
+ * well in the current state of affairs, and is a simpler implementation than
+ * searching for known partitions in the "holes" left between fixed-partition,
+ * _after_ processing DTS nodes.

+ *
+ * This program is free software; you can redistribute it and/or modify it
+ * under the terms of the GNU General Public License version 2 as published
+ * by the Free Software Foundation.
+ *
+ * This driver exposes the data encoded in the "soft_config" flash segment of
+ * MikroTik RouterBOARDs devices. It presents the data in a sysfs folder
+ * named "soft_config". The data is presented in a user/machine-friendly way
+ * with just as much parsing as can be generalized across mikrotik platforms
+ * (as inferred from reverse-engineering).
+ *
+ * The known soft_config tags are presented in the "soft_config" sysfs folder,
+ * with the addition of one specific file named "commit", which is only
+ * available if the driver supports writes to the mtd device: no modifications
+ * made to any of the other attributes are actually written back to flash media
+ * until a true value is input into this file (e.g. [Yy1]). This is to avoid
+ * unnecessary flash wear, and to permit to revert all changes by issuing a
+ * false value ([Nn0]). Reading the content of this file shows the current
+ * status of the driver: if the data in sysfs matches the content of the
+ * soft_config partition, the file will read "clean". Otherwise, it will read
+ * "dirty".
+ *
+ * The writeable sysfs files presented by this driver will accept only inputs
+ * which are in a valid range for the given tag. As a design choice, the driver
+ * will not assess whether the inputs are identical to the existing data.
+ *
+ * Note: PAGE_SIZE is assumed to be >= 4K, hence the device attribute show
+ * routines need not check for output overflow.
+ *
+ * Some constant defines extracted from rbcfg.h by Gabor Juhos

+ * Image Types
+ *
+ * "Standalone Programs" are directly runnable in the environment
+ *	provided by U-Boot; it is expected that (if they behave
+ *	well) you can continue to work in U-Boot after return from
+ *	the Standalone Program.
+ * "OS Kernel Images" are usually images of some Embedded OS which
+ *	will take over control completely. Usually these programs
+ *	will install their own set of exception handlers, device
+ *	drivers, set up the MMU, etc. - this means, that you cannot
+ *	expect to re-enter U-Boot except by resetting the CPU.
+ * "RAMDisk Images" are more or less just data blocks, and their
+ *	parameters (address, size) are passed to an OS kernel that is
+ *	being started.
+ * "Multi-File Images" contain several images, typically an OS
+ *	(Linux) kernel image and one or more data images like
+ *	RAMDisks. This construct is useful for instance when you want
+ *	to boot over the network using BOOTP etc., where the boot
+ *	server provides just a single image file, but you want to get
+ *	for instance an OS kernel and a RAMDisk image.
+ *
+ *	"Multi-File Images" start with a list of image sizes, each
+ *	image size (in bytes) specified by an "uint32_t" in network
+ *	byte order. This list is terminated by an "(uint32_t)0".
+ *	Immediately after the terminating 0 follow the images, one by
+ *	one, all aligned on "uint32_t" boundaries (size rounded up to
+ *	a multiple of 4 bytes - except for the last file).
+ *
+ * "Firmware Images" are binary images containing firmware (like
+ *	U-Boot or FPGA images) which usually will be programmed to
+ *	flash memory.
+ *
+ * "Script files" are command sequences that will be executed by
+ *	U-Boot's command interpreter; this feature is especially
+ *	useful when you configure U-Boot to use a real shell (hush)
+ *	as command interpreter (=> Shell Scripts).
+ *
+ * The following are exposed to uImage header.
+ * New IDs *MUST* be appended at the end of the list and *NEVER*
+ * inserted for backward compatibility.

+Subject: [PATCH] kconfig: abort configuration on unset symbol
+
+When a target configuration has unset Kconfig symbols, the build will
+fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
+
+In case OpenWrt is compiled without either of these preconditions, the
+build will succeed with the symbols in question being unset.
+
+Modify the kernel configuration in a way it fails on unset symbols
+regardless of the aforementioned preconditions.

+To: linux-mtd@lists.infradead.org

+    Richard Weinberger <richard@nod.at>,
+    Miquel Raynal <miquel.raynal@bootlin.com>,
+    David Woodhouse <dwmw2@infradead.org>
+
+Calling device_add_disk while holding mtd_table_mutex leads
+to deadlock in case part_bits!=0 as block partition parsers
+will try to open the newly created disks, trying to acquire
+mutex once again.
+Move device_add_disk to additional function called after
+add partitions of an MTD device have been added and locks
+have been released.

+Subject: [PATCH] drivers: mtd: parsers: add nvmem support to cmdlinepart
+
+Assuming cmdlinepart is only one level deep partition scheme and that
+static partition are also defined in DTS, we can assign an of_node for
+partition declared from bootargs. cmdlinepart have priority than
+fiexed-partition parser so in this specific case the parser doesn't
+assign an of_node. Fix this by searching a defined of_node using a
+similar fixed_partition parser and if a partition is found with the same
+label, check that it has the same offset and size and return the DT
+of_node to correctly use NVMEM cells.

+Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
+
+set-dscpmark is a method of storing the DSCP of an ip packet into
+conntrack mark.  In combination with a suitable tc filter action
+(act_ctinfo) DSCP values are able to be stored in the mark on egress and
+restored on ingress across links that otherwise alter or bleach DSCP.
+
+This is useful for qdiscs such as CAKE which are able to shape according
+to policies based on DSCP.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.
+
+x_tables CONNMARK set-dscpmark target solves the problem of storing the
+DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
+action to restore.
+
+The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
+32bit 'statemask'.  The dscp mask must be 6 contiguous bits and
+represents the area where the DSCP will be stored in the connmark.  The
+state mask is a minimum 1 bit length mask that must not overlap with the
+dscpmask.  It represents a flag which is set when the DSCP has been
+stored in the conntrack mark. This is useful to implement a 'one shot'
+iptables based classification where the 'complicated' iptables rules are
+only run once to classify the connection on initial (egress) packet and
+subsequent packets are all marked/restored with the same DSCP.  A state
+mask of zero disables the setting of a status bit/s.
+
+example syntax with a suitably modified iptables user space application:
+
+iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
+
+Would store the DSCP in the top 6 bits of the 32bit mark field, and use
+the LSB of the top byte as the 'DSCP has been stored' marker.

+Subject: [PATCH] kernel: ct: size the hashtable more adequately
+
+To set the default size of the connection tracking hash table, a divider of
+16384 becomes inadequate for a router handling lots of connections. Divide by
+2048 instead, making the default size scale better with the available RAM.

+
+Adds support for AQR112 and AQR412 which is mostly based on existing code
+with the addition of code configuring the protocol on system side.
+This allows changing the system side protocol without having to deploy a
+different firmware on the PHY.

+Using 2500Base-T SFP modules e.g. on the BananaPi R3 requires manually

+Subject: [PATCH] mxl-gpy: control LED reg from DT
+
+Add dynamic configuration for the LED control registers on MXL PHYs.
+
+This patch has been tested with MaxLinear GPY211C. It is unlikely to be
+accepted upstream, as upstream plans on integrating their own framework
+for handling these LEDs.
+
+For the time being, use this hack to configure PHY driven device-LEDs to
+show the correct state.
+
+A possible alternative might be to expose the LEDs using the kernel LED
+framework and bind it to the netdevice. This might also be upstreamable,
+although it is a considerable extra amount of work.

+Subject: [PATCH 01/19] net-tcp_bbr: broaden app-limited rate sample detection
+
+This commit is a bug fix for the Linux TCP app-limited
+(application-limited) logic that is used for collecting rate
+(bandwidth) samples.
+
+Previously the app-limited logic only looked for "bubbles" of
+silence in between application writes, by checking at the start
+of each sendmsg. But "bubbles" of silence can also happen before
+retransmits: e.g. bubbles can happen between an application write
+and a retransmit, or between two retransmits.
+
+Retransmits are triggered by ACKs or timers. So this commit checks
+for bubbles of app-limited silence upon ACKs or timers.
+
+Why does this commit check for app-limited state at the start of
+ACKs and timer handling? Because at that point we know whether
+inflight was fully using the cwnd.  During processing the ACK or
+timer event we often change the cwnd; after changing the cwnd we
+can't know whether inflight was fully using the old cwnd.

+Subject: [PATCH 02/19] net-tcp_bbr: v2: shrink delivered_mstamp,
+ first_tx_mstamp to u32 to free up 8 bytes
+
+Free up some space for tracking inflight and losses for each
+bw sample, in upcoming commits.
+
+These timestamps are in microseconds, and are now stored in 32
+bits. So they can only hold time intervals up to roughly 2^12 = 4096
+seconds.  But Linux TCP RTT and RTO tracking has the same 32-bit
+microsecond implementation approach and resulting deployment
+limitations. So this is not introducing a new limit. And these should
+not be a limitation for the foreseeable future.

+Subject: [PATCH 03/19] net-tcp_bbr: v2: snapshot packets in flight at transmit
+ time and pass in rate_sample
+
+CC algorithms may want to snapshot the number of packets in flight at
+transmit time and pass in rate_sample, to understand the relationship
+between inflight and losses or ECN signals, to try to find the highest
+inflight value that has acceptable levels of loss/ECN marking.
+
+We split out the code to set an skb's tx.in_flight field into its own
+function, so that this code can be used for the TCP_REPAIR "fake send"
+code path that inserts skbs into the rtx queue without sending them.

+Subject: [PATCH 06/19] net-tcp_bbr: v2: introduce ca_ops->skb_marked_lost() CC
+ module callback API
+
+For connections experiencing reordering, RACK can mark packets lost
+long after we receive the SACKs/ACKs hinting that the packets were
+actually lost.
+
+This means that CC modules cannot easily learn the volume of inflight
+data at which packet loss happens by looking at the current inflight
+or even the packets in flight when the most recently SACKed packet was
+sent. To learn this, CC modules need to know how many packets were in
+flight at the time lost packets were sent. This new callback, combined
+with TCP_SKB_CB(skb)->tx.in_flight, allows them to learn this.
+
+This also provides a consistent callback that is invoked whether
+packets are marked lost upon ACK processing, using the RACK reordering
+timer, or at RTO time.

+Subject: [PATCH 07/19] net-tcp_bbr: v2: adjust skb tx.in_flight upon merge in
+ tcp_shifted_skb()
+
+When tcp_shifted_skb() updates state as adjacent SACKed skbs are
+coalesced, previously the tx.in_flight was not adjusted, so we could
+get contradictory state where the skb's recorded pcount was bigger
+than the tx.in_flight (the number of segments that were in_flight
+after sending the skb).
+
+Normally have a SACKed skb with contradictory pcount/tx.in_flight
+would not matter. However, with SACK reneging, the SACKed bit is
+removed, and an skb once again becomes eligible for retransmitting,
+fragmenting, SACKing, etc. Packetdrill testing verified the following
+sequence is possible in a kernel that does not have this commit:
+
+ - skb N is SACKed
+ - skb N+1 is SACKed and combined with skb N using tcp_shifted_skb()
+   - tcp_shifted_skb() will increase the pcount of prev,
+     but leave tx.in_flight as-is
+   - so prev skb can have pcount > tx.in_flight
+ - RTO, tcp_timeout_mark_lost(), detect reneg,
+   remove "SACKed" bit, mark skb N as lost
+   - find pcount of skb N is greater than its tx.in_flight
+
+I suspect this issue iw what caused the bbr2_inflight_hi_from_lost_skb():
+  WARN_ON_ONCE(inflight_prev < 0)
+to fire in production machines using bbr2.

+ tcp_fragment()
+
+When we fragment an skb that has already been sent, we need to update
+the tx.in_flight for the first skb in the resulting pair ("buff").
+
+Because we were not updating the tx.in_flight, the tx.in_flight value
+was inconsistent with the pcount of the "buff" skb (tx.in_flight would
+be too high). That meant that if the "buff" skb was lost, then
+bbr2_inflight_hi_from_lost_skb() would calculate an inflight_hi value
+that is too high. This could result in longer queues and higher packet
+loss.
+
+Packetdrill testing verified that without this commit, when the second
+half of an skb is SACKed and then later the first half of that skb is
+marked lost, the calculated inflight_hi was incorrect.

+
+Add a a new ca opts flag TCP_CONG_WANTS_CE_EVENTS that allows a
+congestion control module to receive CE events.
+
+Currently congestion control modules have to set the TCP_CONG_NEEDS_ECN
+bit in opts flag to receive CE events but this may incur changes in ECN
+behavior elsewhere. This patch adds a new bit TCP_CONG_WANTS_CE_EVENTS
+that allows congestion control modules to receive CE events
+independently of TCP_CONG_NEEDS_ECN.

+Subject: [PATCH 10/19] net-tcp: re-generalize TSO sizing in TCP CC module API
+
+Reorganize the API for CC modules so that the CC module once again
+gets complete control of the TSO sizing decision. This is how the API
+was set up around 2016 and the initial BBRv1 upstreaming. Later Eric
+Dumazet simplified it. But with wider testing it now seems that to
+avoid CPU regressions BBR needs to have a different TSO sizing
+function.
+
+This is necessary to handle cases where there are many flows
+bottlenecked on the sender host's NIC, in which case BBR's pacing rate
+is much lower than CUBIC/Reno/DCTCP's. Why does this happen? Because
+BBR's pacing rate adapts to the low bandwidth share each flow sees. By
+contrast, CUBIC/Reno/DCTCP see no loss or ECN, so they grow a very
+large cwnd, and thus large pacing rate and large TSO burst size.

+Subject: [PATCH 13/19] net-tcp_bbr: v2: inform CC module of losses repaired by
+ TLP probe
+
+Before this commit, when there is a packet loss that creates a sequence
+hole that is filled by a TLP loss probe, then tcp_process_tlp_ack()
+only informs the congestion control (CC) module via a back-to-back entry
+and exit of CWR. But some congestion control modules (e.g. BBR) do not
+respond to CWR events.
+
+This commit adds a new CA event with which the core TCP stack notifies
+the CC module when a loss is repaired by a TLP. This will allow CC
+modules that do not use the CWR mechanism to have a custom handler for
+such TLP recoveries.

+Define and implement a new per-route feature, RTAX_FEATURE_ECN_LOW.
+
+This feature indicates that the given destination network is a
+low-latency ECN environment, meaning both that ECN CE marks are
+applied by the network using a low-latency marking threshold and also
+that TCP endpoints provide precise per-data-segment ECN feedback in
+ACKs (where the ACK ECE flag echoes the received CE status of all
+newly-acknowledged data segments). This feature indication can be used
+by congestion control algorithms to decide how to interpret ECN
+signals over the given destination network.
+
+This feature is appropriate for datacenter-style ECN marking, such as
+the ECN marking approach expected by DCTCP or BBR congestion control

+Subject: [PATCH 16/19] net-tcp_bbr: v3: update TCP "bbr" congestion control
+ module to BBRv3
+
+BBR v3 is an enhacement to the BBR v1 algorithm. It's designed to aim for lower
+queues, lower loss, and better Reno/CUBIC coexistence than BBR v1.
+
+BBR v3 maintains the core of BBR v1: an explicit model of the network
+path that is two-dimensional, adapting to estimate the (a) maximum
+available bandwidth and (b) maximum safe volume of data a flow can
+keep in-flight in the network. It maintains the estimated BDP as a
+core guide for estimating an appropriate level of in-flight data.
+
+BBR v3 makes several key enhancements:
+
+o Its bandwidth-probing time scale is adapted, within bounds, to allow improved
+coexistence with Reno and CUBIC. The bandwidth-probing time scale is (a)
+extended dynamically based on estimated BDP to improve coexistence with
+Reno/CUBIC; (b) bounded by an interactive wall-clock time-scale to be more
+scalable and responsive than Reno and CUBIC.
+
+o Rather than being largely agnostic to loss and ECN marks, it explicitly uses
+loss and (DCTCP-style) ECN signals to maintain its model.
+
+o It aims for lower losses than v1 by adjusting its model to attempt to stay
+within loss rate and ECN mark rate bounds (loss_thresh and ecn_thresh,
+respectively).
+
+o It adapts to loss/ECN signals even when the application is running out of
+data ("application-limited"), in case the "application-limited" flow is also
+"network-limited" (the bw and/or inflight available to this flow is lower than
+previously estimated when the flow ran out of data).
+
+o It has a three-part model: the model explicit three tracks operating points,
+where an operating point is a tuple: (bandwidth, inflight). The three operating
+points are:
+
+  o latest:        the latest measurement from the current round trip
+  o upper bound:   robust, optimistic, long-term upper bound
+  o lower bound:   robust, conservative, short-term lower bound
+
+These are stored in the following state variables:
+
+  o latest:  bw_latest, inflight_latest
+  o lo:      bw_lo,     inflight_lo
+  o hi:      bw_hi[2],  inflight_hi
+
+To gain intuition about the meaning of the three operating points, it
+may help to consider the analogs in CUBIC, which has a somewhat
+analogous three-part model used by its probing state machine:
+
+  BBR param     CUBIC param
+  -----------   -------------
+  latest     ~  cwnd
+  lo         ~  ssthresh
+  hi         ~  last_max_cwnd
+
+The analogy is only a loose one, though, since the BBR operating
+points are calculated differently, and are 2-dimensional (bw,inflight)
+rather than CUBIC's one-dimensional notion of operating point
+(inflight).
+
+o It uses the three-part model to adapt the magnitude of its bandwidth
+to match the estimated space available in the buffer, rather than (as
+in BBR v1) assuming that it was always acceptable to place 0.25*BDP in
+the bottleneck buffer when probing (commodity datacenter switches
+commonly do not have that much buffer for WAN flows). When BBR v3
+estimates it hit a buffer limit during probing, its bandwidth probing
+then starts gently in case little space is still available in the
+buffer, and the accelerates, slowly at first and then rapidly if it
+can grow inflight without seeing congestion signals. In such cases,
+probing is bounded by inflight_hi + inflight_probe, where
+inflight_probe grows as: [0, 1, 2, 4, 8, 16,...]. This allows BBR to
+keep losses low and bounded if a bottleneck remains congested, while
+rapidly/scalably utilizing free bandwidth when it becomes available.
+
+o It has a slightly revised state machine, to achieve the goals above.
+    BBR_BW_PROBE_UP:    pushes up inflight to probe for bw/vol
+    BBR_BW_PROBE_DOWN:  drain excess inflight from the queue
+    BBR_BW_PROBE_CRUISE: use pipe, w/ headroom in queue/pipe
+    BBR_BW_PROBE_REFILL: try refill the pipe again to 100%, leaving queue empty
+
+o The estimated BDP: BBR v3 continues to maintain an estimate of the
+path's two-way propagation delay, by tracking a windowed min_rtt, and
+coordinating (on an as-ndeeded basis) to try to expose the two-way
+propagation delay by draining the bottleneck queue.
+
+BBR v3 continues to use its min_rtt and (currently-applicable) bandwidth
+estimate to estimate the current bandwidth-delay product. The estimated BDP
+still provides one important guideline for bounding inflight data. However,
+because any min-filtered RTT and max-filtered bw inherently tend to both
+overestimate, the estimated BDP is often too high; in this case loss or ECN
+marks can ensue, in which case BBR v3 adjusts inflight_hi and inflight_lo to
+adapt its sending rate and inflight down to match the available capacity of the
+path.
+
+o Space: Note that ICSK_CA_PRIV_SIZE increased. This is because BBR v3
+requires more space. Note that much of the space is due to support for
+per-socket parameterization and debugging in this release for research
+and debugging. With that state removed, the full "struct bbr" is 140
+bytes, or 144 with padding. This is an increase of 40 bytes over the
+existing ca_priv space.
+
+o Code: BBR v3 reuses many pieces from BBR v1. But it omits the following
+  significant pieces:
+
+  o "packet conservation" (bbr_set_cwnd_to_recover_or_restore(),
+    bbr_can_grow_inflight())
+  o long-term bandwidth estimator ("policer mode")
+
+  The code layout tries to keep BBR v3 code near the bottom of the
+  file, so that v1-applicable code in the top does not accidentally
+  refer to v3 code.
+
+o Docs:
+  See the following docs for more details and diagrams decsribing the BBR v3
+  algorithm:
+    https://datatracker.ietf.org/meeting/104/materials/slides-104-iccrg-an-update-on-bbr-00
+    https://datatracker.ietf.org/meeting/102/materials/slides-102-iccrg-an-update-on-bbr-work-at-google-00
+
+o Internal notes:
+  For this upstream rebase, Neal started from:
+    git show fed518041ac6:net/ipv4/tcp_bbr.c > net/ipv4/tcp_bbr.c
+  then removed dev instrumentation (dynamic get/set for parameters)
+  and code that was only used by BBRv1

+- * BBR congestion control computes the sending rate based on the delivery
+- * rate (throughput) estimated from ACKs. In a nutshell:
++ * BBR is a model-based congestion control algorithm that aims for low queues,
++ * low loss, and (bounded) Reno/CUBIC coexistence. To maintain a model of the
++ * network path, it uses measurements of bandwidth and RTT, as well as (if they
++ * occur) packet loss and/or shallow-threshold ECN signals. Note that although
++ * it can use ECN or loss signals explicitly, it does not require either; it
++ * can bound its in-flight data based on its estimate of the BDP.
+  *
+- *   On each ACK, update our model of the network path:
+- *      bottleneck_bandwidth = windowed_max(delivered / elapsed, 10 round trips)
+- *      min_rtt = windowed_min(rtt, 10 seconds)
+- *   pacing_rate = pacing_gain * bottleneck_bandwidth
+- *   cwnd = max(cwnd_gain * bottleneck_bandwidth * min_rtt, 4)
+- *
+- * The core algorithm does not react directly to packet losses or delays,
+- * although BBR may adjust the size of next send per ACK when loss is
+- * observed, or adjust the sending rate if it estimates there is a
+- * traffic policer, in order to keep the drop rate reasonable.
++ * The model has both higher and lower bounds for the operating range:
++ *   lo: bw_lo, inflight_lo: conservative short-term lower bound
++ *   hi: bw_hi, inflight_hi: robust long-term upper bound
++ * The bandwidth-probing time scale is (a) extended dynamically based on
++ * estimated BDP to improve coexistence with Reno/CUBIC; (b) bounded by

+Subject: [PATCH 17/19] net-tcp_bbr: v3: ensure ECN-enabled BBR flows set ECT
+ on retransmits
+
+Adds a new flag TCP_ECN_ECT_PERMANENT that is used by CCAs to
+indicate that retransmitted packets and pure ACKs must have the
+ECT bit set. This is necessary for BBR, which when using
+ECN expects ECT to be set even on retransmitted packets and ACKs.
+
+Previous to this addition of TCP_ECN_ECT_PERMANENT, CCAs which can use
+ECN but don't "need" it did not have a way to indicate that ECT should
+be set on retransmissions/ACKs.

+Subject: [PATCH 01/25] LRNG: Entropy Source and DRNG Manager
+
+The kernel crypto API contains deterministic random number generators
+(DRNG) which a caller must seed and reseed. The task of seeding a DRNG
+is a non-trivial task requiring the consideration of a significant
+number of aspects. The Entropy Source and DRNG Manager (ESDM) fills
+that gap to transparently seed and reseed DRNGs. A user of the ESDM
+obtains random numbers from an appropriately seeded and initialized
+DRNG. Further, the ESDM controls various entropy sources guaranteeing
+that they are properly initialized and managed.
+
+The ESDM consists of two main parts:
+
+- The entropy source (ES) manager implemented in lrng_es_mgr.c
+  controls the available entropy sources including pulling appropritate
+  amount of data from them for the DRNG manager.
+
+- The DRNG manager provided with lrng_drng_mgr.c controls the DRNG(s)
+  and ensures proper seeding and reseeding.
+
+The entropy source manager controls the entropy sources registered in
+the lrng_es array. The entropy sources provide a function pointer data
+structure that is used to obtain the services from it.
+
+The ES manager triggers the initial seeding of the DRNGs during boot
+time in three stages:
+
+1. The DRNG is seeded from the entropy sources if all entropy sources
+   collectively have at least 32 bits of entropy available. The goal
+   of this step is to ensure that the DRNG receive some initial entropy
+   as early as possible.
+
+2. The DRNG is reseeded from the entropy sources if all entropy sources
+   collectively have at least 128 bits of entropy available.
+
+3. The DRNG is reseeded from the entropy sources if all entropy sources
+   collectively have at least 256 bits of entropy available.
+
+At the time of the reseeding steps, the DRNG requests as much entropy as
+is available in order to skip certain steps and reach the seeding level
+of 256 bits. This may imply that one or more of the aforementioned steps
+are skipped.
+
+In all listed steps, the DRNG is (re)seeded with a number of random bytes
+from the entropy pool that is at most the amount of entropy present in
+the entropy pool. This means that for example when the entropy pool
+contains 128 or more bits of entropy, the DRNG is seeded with that amount
+of entropy as well.
+
+Entropy sources (ES) inform the ES manager when new entropy has been
+collected using the lrng_es_add_entropy() function. That function
+schedules a DRNG (re)seed with the DRNG manager. When the DRNG manager
+requests entropy data, the function lrng_fill_seed_buffer fills the seed
+buffer by iterating through all available ES. The output of all entropy
+sources is concatenated with each other. Further, the seed buffer
+contains the amount of entropy each entropy credits its data. Finally a
+time stamp is added.
+
+The ES trigger such (re)seeding events only as long as not all DRNGs
+are fully seeded with 256 bits of entropy. Once that seeding level is
+reached, the triggers are not further processed.
+
+The DRNG manager initializes the initial DRNG instance during late stage
+of the kernel boot process before user space is triggered. The DRNG is
+seeded at the following occasions:
+
+- when the DRNG is initialized, the available amount of entropy is used,
+
+- during boot time until the DRNG is fully initialized, the reaching of
+  the aforementioned seeding steps of 32/128/256 bits of entropy trigger
+  a reseed of the DRNG.
+
+- at runtime after the elapse of 600 seconds since the last seeding,
+  the DRNG reseeding flag is raised
+
+- at runtime when more than 2^20 generate operations were performed by
+  the given DRNG since last reseeding, the reseeding flag is raised
+
+Raising the reseeding flag implies that the DRNG is seeded in process
+context the next time a caller requests random numbers.
+
+At runtime, the DRNG manager requires at least 128 bits of entropy from
+the entropy sources (or 256 bits when the FIPS mode is active to be
+SP800-90C compliant). It may be possible that the entropy sources may
+not deliver that amount. The DRNG is reseeded with the available amount
+of entropy and continues to operate. Yet, when after 2^30 generate
+requests since the last seeding with 128 bits (or 256 bits in FIPS mode)
+the DRNG cannot be seeded with 128 bits (or 256 bits), the DRNG becomes
+unseeded which means it will not produce random numbers until it is
+fully reseeded again.
+
+To support the DRNG manager, a DRNG implementation is provided with
+lrng_drng_kcapi.c. It uses the kernel crypto API RNG framework and
+allows the specification of the used DRNG with the kernel command line
+option of lrng_drng_kcapi.drng_name. If no reference is given, the
+default is the SP800-90A DRBG. In case the chosen DRNG requires the seed
+to have a certain length, a hash is used bring the entropy buffer into
+the proper size.
+
+In addition, the DRNG manager controls the message digest implementation
+offered to entropy sources when they want to perform a conditioning
+operation. As entropy sources may require the conditioning operation at
+any time, the default is a SHA-256 software hash implementation that
+neither sleeps nor does it need any memory allocation operation.
+Therefore, this hash is available even for the earliest kernel
+operations.
+
+The initial drop of the ESDM includes the entropy source of the
+"auxiliary" pool. This entropy source must always be present. It is an
+entropy pool that is based on the state of a message digest. Every
+insertion of data is a hash update operation. In order to obtain data, a
+hash final operation is performed. The purpose of this auxiliary pool is
+twofold:
+
+- Provide a general interface to inject an arbitrary amount of data from
+  any external source. When providing such data, the caller may specify
+  the amount of entropy it contains.
+
+- The auxiliary pool also provides the backtracking resistance for all
+  entropy sources. Once a seed buffer is filled from all entropy sources
+  it is re-inserted into the auxiliary pool at the same time it is used
+  for seeding the DRNG. Naturally, the insertion of the seed buffer into
+  the auxiliary pool is not credited with any entropy.
+
+If enabled during compile time with the boot option of
+fips=1, the entropy source oversampling is activated. The oversampling
+pulls 128 more bits of entropy than originally requested. This implies
+that when 256 bits of entropy are requested for a (re)seed of a DRNG,
+the ES are queried for 384 bits. This oversampling complies with
+SP800-90C.
+
+This patch set contains a number of header files for subsequent
+additions, but with the current Kconfig settings, these additional
+settings will be folded to noops.

+Subject: [PATCH 02/25] LRNG - allocate one DRNG instance per NUMA node
+
+In order to improve NUMA-locality when serving getrandom(2) requests,
+allocate one DRNG instance per node.
+
+The DRNG instance that is present right from the start of the kernel is
+reused as the first per-NUMA-node DRNG. For all remaining online NUMA
+nodes a new DRNG instance is allocated.
+
+During boot time, the multiple DRNG instances are seeded sequentially.
+With this, the first DRNG instance (referenced as the initial DRNG
+in the code) is completely seeded with 256 bits of entropy before the
+next DRNG instance is completely seeded.
+
+When random numbers are requested, the NUMA-node-local DRNG is checked
+whether it has been already fully seeded. If this is not the case, the
+initial DRNG is used to serve the request.

+Subject: [PATCH 04/25] LRNG - add switchable DRNG support
+
+The DRNG switch support allows replacing the DRNG mechanism of the
+LRNG. The switching support rests on the interface definition of
+include/linux/lrng.h. A new DRNG is implemented by filling in the
+interface defined in this header file.
+
+In addition to the DRNG, the extension also has to provide a hash
+implementation that is used to hash the entropy pool for random number
+extraction.
+
+Note: It is permissible to implement a DRNG whose operations may sleep.
+However, the hash function must not sleep.
+
+The switchable DRNG support allows replacing the DRNG at runtime.
+However, only one DRNG extension is allowed to be loaded at any given
+time. Before replacing it with another DRNG implementation, the possibly
+existing DRNG extension must be unloaded.
+
+The switchable DRNG extension activates the new DRNG during load time.
+It is expected, however, that such a DRNG switch would be done only once
+by an administrator to load the intended DRNG implementation.
+
+It is permissible to compile DRNG extensions either as kernel modules or
+statically. The initialization of the DRNG extension should be performed
+with a late_initcall to ensure the extension is available when user
+space starts but after all other initialization completed.
+The initialization is performed by registering the function call data
+structure with the lrng_set_drng_cb function. In order to unload the
+DRNG extension, lrng_set_drng_cb must be invoked with the NULL
+parameter.
+
+The DRNG extension should always provide a security strength that is at
+least as strong as LRNG_DRNG_SECURITY_STRENGTH_BITS.
+
+The hash extension must not sleep and must not maintain a separate
+state.

+
+The LRNG switchable DRNG support also allows the replacement of the hash
+implementation used as conditioning component. The common generic hash
+support code provides the required callbacks using the synchronous hash
+implementations of the kernel crypto API.
+
+All synchronous hash implementations supported by the kernel crypto API
+can be used as part of the LRNG with this generic support.

+Subject: [PATCH 07/25] LRNG - add SP800-90A DRBG extension
+
+Using the LRNG switchable DRNG support, the SP800-90A DRBG extension is
+implemented.
+
+The DRBG uses the kernel crypto API DRBG implementation. In addition, it
+uses the kernel crypto API SHASH support to provide the hashing
+operation.
+
+The DRBG supports the choice of either a CTR DRBG using AES-256, HMAC
+DRBG with SHA-512 core or Hash DRBG with SHA-512 core. The used core can
+be selected with the module parameter lrng_drbg_type. The default is the
+CTR DRBG.
+
+When compiling the DRBG extension statically, the DRBG is loaded at
+late_initcall stage which implies that with the start of user space, the
+user space interfaces of getrandom(2), /dev/random and /dev/urandom
+provide random data produced by an SP800-90A DRBG.

+Subject: [PATCH 08/25] LRNG - add kernel crypto API PRNG extension
+
+Add runtime-pluggable support for all PRNGs that are accessible via
+the kernel crypto API, including hardware PRNGs. The PRNG is selected
+with the module parameter drng_name where the name must be one that the
+kernel crypto API can resolve into an RNG.
+
+This allows using of the kernel crypto API PRNG implementations that
+provide an interface to hardware PRNGs. Using this extension,
+the LRNG uses the hardware PRNGs to generate random numbers. An
+example is the S390 CPACF support providing such a PRNG.
+
+The hash is provided by a kernel crypto API SHASH whose digest size
+complies with the seedsize of the PRNG.

+
+The atomic DRNG implementation supports the in-kernel use cases which
+request random numbers in atomic contexts. It uses the ChaCha20 DRNG
+which is a code base that does not sleep and it provides an interface to
+callers that does not sleep. This code will only be compiled when the
+LRNG enables the in-kernel drop-in replacement APIs for the existing
+random.c code base.

+Subject: [PATCH 10/25] LRNG - add common timer-based entropy source code
+
+The code shared for timer-based entropy sources offers the following
+support:
+
+* It calculates the greatest common divisor (GCD) during startup time.
+  This allows diving the time stamp by this divisor to eliminate static
+  low-order bits. With the GCD only timer bits that move are considered
+  by the entropy sources.
+
+* It contains the detector code base to identify the presence of a
+  high-resolution timer.
+
+This code is only compiled when an entropy source is present that
+is based on high-resolution time stamps

+Subject: [PATCH 11/25] LRNG - add interrupt entropy source
+
+The interrupt entropy source (ES) consumes the events triggered by the
+kernel invoked with the add_interrupt_randomness. Its main goal is:
+
+- to be extremely fast in the interrupt handler - This is guaranteed by
+  only concatenating the least significant bits of a time stamp into
+  CPU-local entropy pools. Thus, the operation is quasi-lockless. Also,
+  the concatenation is a very trivial operation. Finally, by discarding
+  the high-order bits, attacker-observable timing values are discarded.
+
+- to use only cryptographic primitives for compression.
+
+The IRQ entropy pool collects noise data from interrupt timing.
+Any data received by the LRNG from the interrupt noise sources is
+inserted into a per-CPU entropy pool using a hash operation that can
+be changed during runtime. Per default, SHA-256 is used.
+
+ (a) When an interrupt occurs, the 8 least significant bits of the
+ high-resolution time stamp divided by the greatest common divisor (GCD)
+ is mixed into the per-CPU entropy pool. This time stamp is credited with
+ heuristically implied entropy.
+
+ (b) HID event data like the key stroke or the mouse coordinates are
+ mixed into the per-CPU entropy pool. This data is not credited with
+ entropy by the LRNG.
+
+To speed up the interrupt handling code of the LRNG, the time stamp
+collected for an interrupt event is divided by the greatest common
+divisor to eliminate fixed low bits and then truncated to the 8 least
+significant bits. 1024 truncated time stamps are concatenated and then
+jointly inserted into the per-CPU entropy pool. During boot time,
+until the fully seeded stage is reached, each time stamp with its
+32 least significant bits is are concatenated. When 1024/32 = 32 such
+events are received, they are injected into the per-CPU entropy pool.
+
+The IRQ ES is only enabled if the existing random number generator
+(random.c) is not compiled.

+
+The scheduler can be used as a source of entropy. This requires the
+presence of a hook that invokes the entropy source implementation.
+
+When the scheduler-based entropy source is not compiled, the hook is
+folded into a noop which does not affect the scheduler in any way.

+Subject: [PATCH 13/25] LRNG - add scheduler-based entropy source
+
+The scheduler-based entropy source (ES) consumes the events triggered by
+the kernel invoked with the add_sched_randomness. Its main goal is:
+
+- to be extremely fast in the scheduler context - This is guaranteed by
+  only concatenating the least significant bits of a time stamp into
+  CPU-local entropy pools. Thus, the operation is quasi-lockless. Also,
+  the concatenation is a very trivial operation. Finally, by discarding
+  the high-order bits, attacker-observable timing values are discarded.
+
+- to use only cryptographic primitives for compression.
+
+The scheduler entropy pool collects noise data from context-switch
+timing. Any data received by the LRNG from the interrupt noise sources
+is inserted into a per-CPU entropy pool using a concatenation operation.
+The following processing concept is applied
+
+ (a) When an interrupt occurs, the 8 least significant bits of the
+ high-resolution time stamp divided by the greatest common divisor (GCD)
+ is mixed into the per-CPU entropy pool. This time stamp is credited with
+ heuristically implied entropy.
+
+ (b) Only in process context when a reseed of the DRNG is requested,
+ the compression of the entropy pool data is performed using a hash.
+ When the entropy pool is full (i.e. sufficient scheduling event data
+ is received and yet no compression is performed), the oldest entropy
+ pool entries are overwritten with the current entry. Thus, the entropy
+ pool acts as a ring buffer.
+
+To speed up the scheduling operation code of the LRNG, the time stamp
+collected for an interrupt event is divided by the greatest common
+divisor to eliminate fixed low bits and then truncated to the 8 least
+significant bits. 1024 truncated time stamps are concatenated and then
+jointly inserted into the per-CPU entropy pool. During boot time,
+until the fully seeded stage is reached, each time stamp with its
+32 least significant bits is are concatenated. When 1024/32 = 32 such
+events are received, they are injected into the per-CPU entropy pool.
+
+Considering the possibility that IRQ events cause at the same time
+scheduling events (e.g. the IRQ tasklet is executed), only one of those
+two entropy sources can ever be configured to deliver entropy. The
+respective other ES may deliver data, but never increases the entropy
+estimator of the LRNG.

+Subject: [PATCH 14/25] LRNG - add SP800-90B compliant health tests
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Implement health tests for LRNG's internal entropy sources as mandated
+by SP-800-90B. These internal entropy sources (scheduler and IRQ ES)
+both rest on high-resolution time stamps as their noise source. The patch
+contains the following health tests which are independently enabled and
+applied for the mentioned entropy sources.:
+
+- stuck test: The stuck test calculates the first, second and third
+  discrete derivative of the time stamp to be processed by the hash
+  for the per-CPU entropy pool. Only if all three values are non-zero,
+  the received time delta is considered to be non-stuck.
+
+- SP800-90B Repetition Count Test (RCT): The LRNG uses an enhanced
+  version of the RCT specified in SP800-90B section 4.4.1. Instead of
+  counting identical back-to-back values, the input to the RCT is the
+  counting of the stuck values during the processing of received
+  interrupt events. The RCT is applied with alpha=2^-30 compliant to
+  the recommendation of FIPS 140-2 IG 9.8. During the counting operation,
+  the LRNG always calculates the RCT cut-off value of C. If that value
+  exceeds the allowed cut-off value, the LRNG will trigger the health
+  test failure discussed below. An error is logged to the kernel log
+  that such RCT failure occurred. This test is only applied and
+  enforced in FIPS mode, i.e. when the kernel compiled with
+  CONFIG_CONFIG_FIPS is started with fips=1.
+
+- SP800-90B Adaptive Proportion Test (APT): The LRNG implements the
+  APT as defined in SP800-90B section 4.4.2. The applied significance
+  level again is alpha=2^-30 compliant to the recommendation of FIPS
+  140-2 IG 9.8.
+
+The aforementioned health tests are applied to the first 1,024 time stamps
+obtained from interrupt events. In case one error is identified for either
+the RCT, or the APT, the collected entropy is invalidated and the
+SP800-90B startup health test is restarted.
+
+As long as the SP800-90B startup health test is not completed, all LRNG
+random number output interfaces that may block will block and not generate
+any data. This implies that only those potentially blocking interfaces are
+defined to provide random numbers that are seeded with the interrupt noise
+source being SP800-90B compliant. All other output interfaces will not be
+affected by the SP800-90B startup test and thus are not considered
+SP800-90B compliant.
+
+At runtime, the SP800-90B APT and RCT are applied to each time stamp
+generated for a received interrupt. When either the APT and RCT indicates
+a noise source failure, the LRNG is reset to a state it has immediately
+after boot:
+
+- all entropy counters are set to zero
+
+- the SP800-90B startup tests are re-performed which implies that
+getrandom(2) would block again until new entropy was collected
+
+To summarize, the following rules apply:
+
+• SP800-90B compliant output interfaces
+
+  - /dev/random
+
+  - getrandom(2) system call
+
+  -  get_random_bytes kernel-internal interface when being triggered by
+     the callback registered with add_random_ready_callback
+
+• SP800-90B non-compliant output interfaces
+
+  - /dev/urandom
+
+  - get_random_bytes kernel-internal interface called directly
+
+  - randomize_page kernel-internal interface
+
+  - get_random_u32 and get_random_u64 kernel-internal interfaces
+
+  - get_random_u32_wait, get_random_u64_wait, get_random_int_wait, and
+    get_random_long_wait kernel-internal interfaces
+
+If either the RCT, or the APT health test fails irrespective whether
+during initialization or runtime, the following actions occur:
+
+  1. The entropy of the entire entropy pool is invalidated.
+
+  2. All DRNGs are reset which imply that they are treated as being
+     not seeded and require a reseed during next invocation.
+
+  3. The SP800-90B startup health test are initiated with all
+     implications of the startup tests. That implies that from that point
+     on, new events must be observed and its entropy must be inserted into
+     the entropy pool before random numbers are calculated from the
+     entropy pool.
+
+Further details on the SP800-90B compliance and the availability of all
+test tools required to perform all tests mandated by SP800-90B are
+provided at [1].
+
+The entire health testing code is compile-time configurable.
+
+The patch provides a CONFIG_BROKEN configuration of the APT / RCT cutoff
+values which have a high likelihood to trigger the health test failure.
+The BROKEN APT cutoff is set to the exact mean of the expected value if
+the time stamps are equally distributed (512 time stamps divided by 16
+possible values due to using the 4 LSB of the time stamp). The BROKEN
+RCT cutoff value is set to 1 which is likely to be triggered during
+regular operation.

+Subject: [PATCH 15/25] LRNG - add random.c entropy source support
+
+The random.c implementation can be used as an entropy source by the
+LRNG. This support can be enabled at compile time.
+
+The entropy rate can be set at compile time which is only applied:
+
+- once the random.c considers itself fully seeded, and
+
+- the kernel does not operate in FIPS mode (i.e. fips=1 is not set at
+  the kernel command line)
+
+If one of these properties is not set, the ES will obtain data, but will
+credit it with zero bits of entropy. For the first bullet, it is clear
+why it will have zero bits of entropy. But for the second property, this
+is set because the random.c is not operating SP800-90B compliant and
+thus must be treated to not deliver any entropy in FIPS mode.

+
+Certain CPUs provide instructions giving access to an entropy source
+(e.g. RDSEED on Intel/AMD, DARN on POWER, etc.). The LRNG can utilize

+
+Some CPU entropy sources (e.g. POWER DARN, RISC-V) are defined to

+Subject: [PATCH 17/25] LRNG - add Jitter RNG fast noise source
+
+The Jitter RNG fast noise source implemented as part of the kernel
+crypto API is queried for 256 bits of entropy at the time the seed
+buffer managed by the LRNG is about to be filled.
+
+The default entropy rate is set to 16 bits of entropy per 256 bits of
+data. In FIPS mode, the ratio is set to 256 bits of entropy per 256 bits
+of data considering that the Jitter RNG passed the NIST ENT validation
+to claim full entropy.

+Subject: [PATCH 18/25] LRNG - add option to enable runtime entropy rate
+ configuration
+
+The entropy rate for the different entropy sources is configured at
+compile time. Enabling the option CONFIG_LRNG_RUNTIME_ES_CONFIG allows
+the entropy sources' entropy rate to be adjusted at runtime or boot
+time. The different options are:
+
+- IRQ ES: lrng_es_irq.irq_entropy
+
+- Scheduler ES: lrng_es_sched.sched_entropy
+
+- CPU ES: lrng_es_cpu.cpu_entropy
+
+- Kernel ES: lrng_es_krng.krng_entropy
+
+- Jitter RNG ES: lrng_es_jent.jent_entropy
+
+The values to be specified there must apply the rationale given for the
+different CONFIG_LRNG_*_ENTROPY_RATE kernel configuration options.

+Subject: [PATCH 19/25] LRNG - add interface for gathering of raw entropy
+
+The test interface allows a privileged process to capture the raw
+unconditioned noise that is collected by the LRNG for statistical
+analysis. Such testing allows the analysis how much entropy
+the interrupt noise source provides on a given platform.
+Extracted noise data is not used to seed the LRNG. This
+is a test interface and not appropriate for production systems.
+Yet, the interface is considered to be sufficiently secured for
+production systems.
+
+The raw entropy collection is provided for the internal entropy sources
+under full control of the LRNG: the IRQ ES and the scheduler-based ES.
+The test interfaces are only enabled for the given ES if the ES is
+enabled itself.
+
+Access to the data is given through the lrng_raw debugfs file. The
+data buffer should be multiples of sizeof(u32) to fill the entire
+buffer. Using the option lrng_testing.boot_test=1 the raw noise of
+the first 1000 entropy events since boot can be sampled.
+
+This test interface allows generating the data required for
+analysis whether the LRNG is in compliance with SP800-90B
+sections 3.1.3 and 3.1.4.
+
+In addition, the test interface allows gathering of the concatenated raw
+entropy data to verify that the concatenation works appropriately.
+This includes sampling of the following raw IRQ data:
+
+* high-resolution time stamp obtained for an IRQ event
+
+* Jiffies
+
+* IRQ number
+
+* return instruction pointer
+
+* interrupt register state
+
+* array logic batching the high-resolution time stamp
+
+* a performance monitor of the IRQ ES
+
+The sampling of the following scheduler-based ES data is possible:
+
+* high-resolution time stamp obtained for a context switch event
+
+* the PID of the process scheduled to
+
+* the process' start time value
+
+* the process' context switch numbers value
+
+* a performance monitor of the scheduler-based ES
+
+Also, a testing interface to support ACVT of the hash implementation
+is provided. The reason why only hash testing is supported (as
+opposed to also provide testing for the DRNG) is the fact that the
+LRNG software hash implementation contains glue code that may
+warrant testing in addition to the testing of the software ciphers
+via the kernel crypto API. Also, for testing the CTR-DRBG, the
+underlying AES implementation would need to be tested. However,
+such AES test interface cannot be provided by the LRNG as it has no
+means to access the AES operation.
+
+If a test interface is not compiled, its code is a noop which has no
+impact on the performance.

+Subject: [PATCH 20/25] LRNG - add power-on and runtime self-tests
+
+Parts of the LRNG are already covered by self-tests, including:
+
+* Self-test of SP800-90A DRBG provided by the Linux kernel crypto API.
+
+* Self-test of the PRNG provided by the Linux kernel crypto API.
+
+* Raw noise source data testing including SP800-90B compliant
+  tests when enabling CONFIG_LRNG_HEALTH_TESTS
+
+This patch adds the self-tests for the remaining critical functions of
+the LRNG that are essential to maintain entropy and provide
+cryptographic strong random numbers. The following self-tests are
+implemented:
+
+* Self-test of the time array maintenance. This test verifies whether
+the time stamp array management to store multiple values in one integer
+implements a concatenation of the data.
+
+* Self-test of the software hash implementation ensures that this
+function operates compliant to the FIPS 180-4 specification. The
+self-test performs a hash operation of a zeroized per-CPU data array.
+
+* Self-test of the ChaCha20 DRNG is based on the self-tests that are
+already present and implemented with the stand-alone user space
+ChaCha20 DRNG implementation available at [1]. The self-tests cover
+different use cases of the DRNG seeded with known seed data.
+
+The status of the LRNG self-tests is provided with the selftest_status
+SysFS file. If the file contains a zero, the self-tests passed. The
+value 0xffffffff means that the self-tests were not executed. Any other
+value indicates a self-test failure.
+
+The self-test may be compiled to panic the system if the self-test
+fails.
+
+All self-tests operate on private state data structures. This implies
+that none of the self-tests have any impact on the regular LRNG
+operations. This allows the self-tests to be repeated at runtime by
+writing anything into the selftest_status SysFS file.

+Subject: [PATCH 21/25] LRNG - sysctls and /proc interface
+
+The LRNG sysctl interface provides the same controls as the existing
+/dev/random implementation. These sysctls behave identically and are
+implemented identically. The goal is to allow a possible merge of the
+existing /dev/random implementation with this implementation which
+implies that this patch tries have a very close similarity. Yet, all
+sysctls are documented at [1].
+
+The sysctl implementation is only enabled if the existing random.c file
+is not compiled.

+Subject: [PATCH 22/25] LRMG - add drop-in replacement random(4) API
+
+The LRNG is intended to be a full replacement of the existing random.c.
+This also includes the providing of a full API and ABI compliant drop-in
+replacement of all APIs offered by random.c.
+
+These LRNG interfaces are compiled when the random.c is not compiled
+any more.

+Subject: [PATCH 23/25] LRNG - add kernel crypto API interface
+
+The LRNG can be registered with the kernel crypto API's random number
+generator framework. This offers a random number generator with the name
+"lrng" and a priority that is intended to be higher than the existing
+RNG implementations.

+
+The MPTCP path manager event handler mptcp_pm_connection_closed
+interface has been added in the commit 1b1c7a0ef7f3 ("mptcp: Add path
+manager interface") but it was an empty function from then on.
+
+With such name, it sounds good to invoke mptcp_event with the
+MPTCP_EVENT_CLOSED event type from it. It also removes a bit of
+duplicated code.

+Subject: [PATCH 14/28] bpf: Add bpf_mptcp_sched_ops
+
+This patch implements a new struct bpf_struct_ops: bpf_mptcp_sched_ops.
+Register and unregister the bpf scheduler in .reg and .unreg.
+
+Add write access for the scheduled flag of struct mptcp_subflow_context
+in .btf_struct_access.
+
+This MPTCP BPF scheduler implementation is similar to BPF TCP CC. And
+net/ipv4/bpf_tcp_ca.c is a frame of reference for this patch.

+Subject: [PATCH 16/28] selftests/bpf: Add mptcp subflow example
+
+Move Nicolas' patch into bpf selftests directory. This example adds a
+different mark (SO_MARK) on each subflow, and changes the TCP CC only on
+the first subflow.
+
+From the userspace, an application can do a setsockopt() on an MPTCP
+socket, and typically the same value will be propagated to all subflows
+(paths). If someone wants to have different values per subflow, the
+recommended way is to use BPF. So it is good to add such example here,
+and make sure there is no regressions.
+
+This example shows how it is possible to:
+
+    Identify the parent msk of an MPTCP subflow.
+    Put different sockopt for each subflow of a same MPTCP connection.
+
+Here especially, two different behaviours are implemented:
+
+    A socket mark (SOL_SOCKET SO_MARK) is put on each subflow of a same
+    MPTCP connection. The order of creation of the current subflow defines
+    its mark. The TCP CC algorithm of the very first subflow of an MPTCP
+    connection is set to "reno".
+
+This is just to show it is possible to identify an MPTCP connection, and
+set socket options, from different SOL levels, per subflow. It is easy
+to verify with 'ss' that these modifications have been applied
+correctly. That's what the next patch is going to do.
+
+Nicolas' code comes from:
+
+    commit 4d120186e4d6 ("bpf:examples: update mptcp_set_mark_kern.c")
+
+from the MPTCP repo https://github.com/multipath-tcp/mptcp_net-next (the
+"scripts" branch), and it has been adapted by Geliang.

+Subject: [PATCH 17/28] selftests/bpf: Add getsockopt to inspect mptcp subflow
+
+This patch adds a "cgroup/getsockopt" way to inspect the subflows of an
+mptcp socket. That will be used by the next commit to verify the socket
+options set on each subflow.
+
+This extra "cgroup/getsockopt" prog walks the msk->conn_list and use
+bpf_core_cast to cast a pointer for readonly. It allows to inspect all
+the fields of a structure.
+
+mptcp_subflow_tcp_sock(), mptcp_for_each_stubflow() and other helpers
+related to list_entry have been added into a new progs/mptcp_bpf.h file.

+Subject: [PATCH 18/28] selftests/bpf: Add mptcp subflow subtest
+
+This patch adds a subtest named test_subflow to load and verify the newly
+added mptcp subflow example in test_mptcp. Add a helper endpoint_init()
+to add a new subflow endpoint. Add another helper ss_search() to verify the
+fwmark and congestion values set by mptcp_subflow prog using setsockopts.

+Subject: [PATCH 19/28] selftests/bpf: Add bpf scheduler test
+
+This patch extends the MPTCP test base to support MPTCP packet scheduler
+tests. Add a new test to use the default in-kernel scheduler.
+
+In the new helper sched_init(), add two veth net devices to simulate the
+multiple addresses case. Use 'ip mptcp endpoint' command to add the new
+endpoint ADDR_2 to PM netlink. Use sysctl to set net.mptcp.scheduler to
+use the given sched.
+
+Invoke start_mptcp_server() to start the server on ADDR_1, and invoke
+connect_to_fd() to connect with the server from the client. Then invoke
+send_data() to send data.
+
+Some code in send_data() is from prog_tests/bpf_tcp_ca.c.
+
+Add time metrics for BPF tests to compare the performance of each
+schedulers. Run prog_tests with '-v' option can print out the running
+time of each test.
+
+Use the new helper has_bytes_sent() to check the bytes_sent filed of 'ss'
+output after send_data() to make sure no data has been sent on ADDR_2.
+All data has been sent on the first subflow.
+
+Invoke the new helper sched_cleanup() to set back net.mptcp.scheduler to
+default, flush all mptcp endpoints, and delete the veth net devices.

+Subject: [PATCH 20/28] selftests/bpf: Add bpf_first scheduler & test
+
+This patch implements the simplest MPTCP scheduler, named bpf_first,
+which always picks the first subflow to send data. It's a sample of
+MPTCP BPF scheduler implementations.
+
+This patch defines MPTCP_SCHED_TEST macro, a template for all scheduler
+tests. Every scheduler is identified by argument name, and use sysctl
+to set net.mptcp.scheduler as "bpf_name" to use this sched. Add two
+veth net devices to simulate the multiple addresses case. Use 'ip mptcp
+endpoint' command to add the new endpoint ADDR2 to PM netlink. Arguments
+addr1/add2 means whether the data has been sent on the first/second
+subflow or not. Send data and check bytes_sent of 'ss' output after it
+using send_data_and_verify().
+
+Using MPTCP_SCHED_TEST macro to add a new test for this bpf_first
+scheduler, the arguments "1 0" means data has been only sent on the
+first subflow ADDR1. Run this test by RUN_MPTCP_TEST macro.

+Subject: [PATCH 24/28] bpf: Export more bpf_burst related functions
+
+sk_stream_memory_free() and tcp_rtx_and_write_queues_empty() are needed
+to export into the BPF context for bpf_burst scheduler. But these two
+functions are inline ones. So this patch added two wrappers for them,
+and export the wrappers in the BPF context.
+
+Add more bpf_burst related functions into bpf_mptcp_sched_kfunc_set to make
+sure these helpers can be accessed from the BPF context.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+
+There are broken devices in the wild that handle duplicate IP address
+detection by sending out ARP requests for the IP that they received from a
+DHCP server and refuse the address if they get a reply.
+When proxyarp is enabled, they would go into a loop of requesting an address

+Date: Mon, 22 Feb 2016 18:09:44 +0000
+Subject: [PATCH] MIPS: Add barriers between dcache & icache flushes
+
+Index-based cache operations may be arbitrarily reordered by out of
+order CPUs. Thus code which writes back the dcache & then invalidates
+the icache using indexed cache ops must include a barrier between
+operating on the 2 caches in order to prevent the scenario in which:
+
+  - icache invalidation occurs.
+
+  - icache fetch occurs, due to speculation.
+
+  - dcache writeback occurs.
+
+If the above were allowed to happen then the icache would contain stale
+data. Forcing the dcache writeback to complete before the icache
+invalidation avoids this.

+
+This change allows OpenWRT to patch resulting kernel binary with
+external .dtb.
+
+That allows us to re-use exactky the same vmlinux on different boards
+given its ARC core configurations match (at least cache line sizes etc).
+
+""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
+.dtb right after it, keeping the string in place.

+Subject: [PATCH] mips: kernel: fix detect_memory_region() function
+
+1. Do not use memcmp() on unallocated memory, as the new introduced
+   fortify dynamic object size check[1] will report unexpected result.
+2. Use a fixed pattern instead of a random function pointer as the
+   magic value.
+3. Flip magic value and double check it.
+4. Enable this feature only for 32-bit CPUs. Currently, only ath79 and
+   ralink CPUs are using it.

+Subject: [PATCH] mtd: spi-nor: write support for minor aligned partitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Do not prevent writing to mtd partitions where a partition boundary sits
+on a minor erasesize boundary.
+This addresses a FIXME that has been present since the start of the
+linux git history:
+/* Doesn't start on a boundary of major erase size */
+/* FIXME: Let it be writable if it is on a boundary of
+ * _minor_ erase size though */
+
+Allow a uniform erase region spi-nor device to be configured
+to use the non-uniform erase regions code path for an erase with:
+CONFIG_MTD_SPI_NOR_USE_VARIABLE_ERASE=y
+
+On supporting hardware (SECT_4K: majority of current SPI-NOR device)
+provide the facility for an erase to use the least number
+of SPI-NOR operations, as well as access to 4K erase without
+requiring CONFIG_MTD_SPI_NOR_USE_4K_SECTORS
+
+Introduce erasesize_minor to the mtd struct,
+the smallest erasesize supported by the device
+
+On existing devices, this is useful where write support is wanted
+for data on a 4K partition, such as some u-boot-env partitions,
+or RouterBoot soft_config, while still netting the performance
+benefits of using 64K sectors
+
+Performance:
+time mtd erase firmware
+OpenWrt 5.10 ramips MT7621 w25q128jv 0xfc0000 partition length

+checkpatch does not like the printk(KERN_WARNING
+these should be changed separately beforehand?
+
+Changes v1 -> v2:
+Added mtdcore sysfs for erasesize_minor
+Removed finding minor erasesize for variable erase regions device,
+as untested and no responses regarding it.
+Moved IF_ENABLED for SPINOR variable erase to guard setting
+erasesize_minor in spi-nor/core.c
+Removed setting erasesize to minor where partition boundaries require
+minor erase to be writable
+Simplified minor boundary check by relying on minor being a factor of
+major
+
+Changes RFC -> v1:
+Fix uninitialized variable smatch warning

+Subject: kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.

+Subject: [PATCH] mtd: spinand: Add support for Etron EM73D044VCx
+
+Airoha is a new ARM platform based on Cortex-A53 which has recently been
+merged into linux-next.
+
+Due to BootROM limitations on this platform, the Cortex-A53 can't run in
+Aarch64 mode and code must be compiled for 32-Bit ARM.
+
+This support is based mostly on those linux-next commits backported
+for kernel 5.15.
+
+Patches:
+1 - platform support = linux-next
+2 - clock driver = linux-next
+3 - gpio driver = linux-next
+4 - linux,usable-memory-range dts support = linux-next
+5 - mtd spinand driver
+6 - spi driver
+7 - pci driver (kconfig only, uses mediatek PCI) = linux-next
+
+Still missing:
+- Ethernet driver
+- Sysupgrade support
+
+A.t.m there exists one subtarget EN7523 with only one evaluation
+board.
+
+The initramfs can be run with the following commands from u-boot:
+-
+u-boot> setenv bootfile \
+	openwrt-airoha-airoha_en7523-evb-initramfs-kernel.bin
+u-boot> tftpboot
+u-boot> bootm 0x81800000

+Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+  compatible = "mtd-concat";
+
+  devices = <&flash0 &flash1>;
+
+  partitions {
+    ...
+  };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+Subject: [PATCH 1/2] mtd: spi-nor: locking support for MX25L6405D
+
+Macronix MX25L6405D supports locking with four block-protection bits.
+Currently, the driver only sets three bits.  If the bootloader does not
+sustain the flash chip in an unlocked state, the flash might be
+non-writeable. Add the corresponding flag to enable locking support with
+four bits in the status register.
+
+Tested on Nanostation M2 XM.
+
+Similar to commit 7ea40b54e83b ("mtd: spi-nor: enable locking support for
+MX25L12805D")

+Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix
+
+Macronix flash chips seem to consist of only one status register.
+These chips will not work with the "16-bit Write Status (01h) Command".
+Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
+
+Tested with MX25L6405D.

+Subject: [PATCH] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+Subject: [PATCH] net: bridge: fix switchdev host mdb entry updates
+
+When a mdb entry is removed, the bridge switchdev code can issue a
+switchdev_port_obj_del call for a port that was not offloaded.
+
+This leads to an imbalance in switchdev_port_obj_add/del calls, since
+br_switchdev_mdb_replay has not been called for the port before.
+
+This can lead to potential multicast forwarding issues and messages such as:
+mt7915e 0000:01:00.0 wl1-ap0: Failed to del Host Multicast Database entry
+	(object id=3) with error: -ENOENT (-2).
+
+Fix this issue by checking the port offload status when iterating over
+lower devs.

+set to 0. When both ingress and egress port have no hwdom,
+'cb->src_hwdom != p->hwdom' indicates that the packet is already known in
+the target domain - which it isn't - and the packet is wrongly dropped.
+
+The error was found on a bridge containing a wifi device and a VLAN
+tagging device (e.g. eth0.12). With VLAN filtering, this shouldn't happen.
+
+This patch adds a check for p->hwdom != 0 before comparing hardware
+domains to restore forwarding between ports with hwdom = 0.
+
+fwd_hwdoms are only set for ports with offloading enabled, which also
+implies a valid hwdom, so the check '!test_bit(p->hwdom, &cb->fwd_hwdoms)'
+doesn't fail in this way (yet - fingers crossed..) and it is left in place.

+Subject: Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: [PATCH] net: remove NETIF_F_GSO_FRAGLIST from NETIF_F_GSO_SOFTWARE
+
+Several drivers set NETIF_F_GSO_SOFTWARE, but mangle fraglist GRO packets
+in a way that they can't be properly segmented anymore.
+In order to properly deal with this, remove fraglist GSO from
+NETIF_F_GSO_SOFTWARE and switch to NETIF_F_GSO_SOFTWARE_ALL (which includes
+fraglist GSO) in places where it's safe to add.

+Subject: [PATCH] of/of_net: write back netdev MAC-address to device-tree
+
+The label-mac logic relies on the mac-address property of a netdev
+devices of-node. However, the mac address can also be stored as a
+different property or read from e.g. an mtd device.
+
+Create this node when reading a mac-address from OF if it does not
+already exist and copy the mac-address used for the device to this
+property. This way, the MAC address can be accessed using procfs.

+Subject: [PATCH] netfilter: nf_tables: ignore -EOPNOTSUPP on flowtable device
+ offload setup
+
+On many embedded devices, it is common to configure flowtable offloading for
+a mix of different devices, some of which have hardware offload support and
+some of which don't.
+The current code limits the ability of user space to properly set up such a
+configuration by only allowing adding devices with hardware offload support to
+a offload-enabled flowtable.
+Given that offload-enabled flowtables also imply fallback to pure software
+offloading, this limitation makes little sense.
+Fix it by not bailing out when the offload setup returns -EOPNOTSUPP

+Subject: [PATCH] net: phy: populate host_interfaces when attaching PHY
+
+Use bitmask of interfaces supported by the MAC for the PHY to choose
+from if the declared interface mode is among those using a single pair
+of SerDes lanes.
+This will allow 2500Base-T PHYs to switch to SGMII on most hosts, which
+results in half-duplex being supported in case the MAC supports them.
+Without this change, 2500Base-T PHYs will always operate in 2500Base-X
+mode with rate-matching, which is not only wasteful in terms of energy
+consumption, but also limits the supported interface modes to
+full-duplex only.

+
+Some devices (e.g. wireless APs) can't have devices behind them be part of
+a bridge topology with redundant links, due to address limitations.
+Additionally, broadcast traffic on these devices is somewhat expensive, due to
+the low data rate and wakeups of clients in powersave mode.
+This knob can be used to ensure that BPDU packets are never sent or forwarded

+Subject: [PATCH 4/4] net: dsa: qca8k: add support for port_change_master
+
+Add support for port_change_master to permit assigning an alternative
+CPU port if the switch have both CPU port connected or create a LAG on
+both CPU port and assign the LAG as DSA master.
+
+On port change master request, we check if the master is a LAG.
+With LAG we compose the cpu_port_mask with the CPU port in the LAG, if
+master is a simple dsa_port, we derive the index.
+
+Finally we apply the new cpu_port_mask to the LOOKUP MEMBER to permit
+the port to receive packet by the new CPU port setup for the port and we
+refresh the CPU ports LOOKUP MEMBER configuration to reflect the new
+user port state.
+
+port_lag_join/leave is updated to refresh the user ports if we detect
+that the LAG is a DSA master and we have user port using it as a master.

+
+Enable assisted learning on CPU port.
+
+It has been verified that there is a problem in packet roaming
+from one BSS to another in the same security settings from one
+physical R7800 to another physical R7800 where they are in the
+same L2 broadcast domain backhauled/linked together via one
+of the ethernet ports.
+DHCP will fail to complete and traffic cannot flow for around 300
+seconds.

+ PHYs
+
+MAC drivers don't use SGMII in-band autonegotiation unless told to do so
+in device tree using 'managed = "in-band-status"'. When using MDIO to
+access a PHY, in-band-status is unneeded as we have link-status via
+MDIO. Switch off SGMII in-band autonegotiation using magic values.

+Subject: [PATCH] net: phy: realtek: make sure paged read is protected by mutex
+
+As we cannot rely on phy_read_paged function before the PHY is
+identified, the paged read in rtlgen_supports_2_5gbps needs to be open
+coded as it is being called by the match_phy_device function, ie. before
+.read_page and .write_page have been populated.
+
+Make sure it is also protected by the MDIO bus mutex and use
+rtl821x_write_page instead of 3 individually locked MDIO bus operations.

+Subject: [PATCH] net: phy: realtek: work around broken SerDes
+
+For still unknown reasons the SerDes init sequence may sometimes
+time out because a self-clearing bit never clears, indicating the
+PHY has entered an unrecoverable error state.
+
+Work-around the issue by triggering a hardware reset and retry the
+setup sequence while warning the user that this has happened.
+This is really more of a work-around than a fix, and should be
+replaced by a better actual fix in future (hopefully).

+
+RealTek's PHYs by default also listen on MDIO address 0 which is defined
+as broadcast address. This can lead to problems if there is an actual PHY
+(such as MT7981 built-in PHY) present at this address, as accessing that
+PHY may then confuse the RealTek PHY.
+
+Disabled listening on the MDIO broadcast address to avoid such problems.

+
+The purpose of resetting the TX queue is to reset the
+byte and packet count as well as to clear the software
+flow control XOFF bit.
+
+MediaTek developers pointed out that netdev_reset_queue would only
+resets queue 0 of the network device.
+Queues that are not reset may cause unexpected issues.
+
+Packets may stop being sent after reset and "transmit timeout" log may
+be displayed.
+
+Import fix from MediaTek's SDK to resolve this issue.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: use napi_build_skb()
+
+The napi_build_skb() can reuse the skb in skb cache per CPU or
+can allocate skbs in bulk, which helps improve the performance.

+Subject: [PATCH] net: ethernet: mediatek: increase QDMA RESV_BUF size
+
+Increase QDMA RESV_BUF from 2K to 3K for netsys v2 to match Mediatek SDK[1].
+This helps reduce the possibility of Ethernet transmit timeouts.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: add paths and SerDes modes for
+ MT7988
+
+MT7988 comes with a built-in 2.5G PHY as well as SerDes lanes to
+connect external PHYs or transceivers in USXGMII, 10GBase-R, 5GBase-R,
+2500Base-X, 1000Base-X and Cisco SGMII interface modes.
+
+Implement support for configuring for the new paths to SerDes interfaces
+and the internal 2.5G PHY.
+
+Add USXGMII PCS driver for 10GBase-R, 5GBase-R and USXGMII mode, and
+setup the new PHYA on MT7988 to access the also still existing old
+LynxI PCS for 1000Base-X, 2500Base-X and Cisco SGMII PCS interface
+modes.

+Subject: [PATCH net-next 3/4] net: ethernet: mtk_eth_soc: reduce rx ring size for older chipsets
+Date: Tue, 15 Oct 2024 13:09:37 +0200
+
+Commit c57e55819443 ("net: ethernet: mtk_eth_soc: handle dma buffer
+size soc specific") resolved some tx timeout issues by bumping FQ and
+tx ring sizes from 512 to 2048 entries (the value used in the MediaTek
+SDK), however it also changed the rx ring size for all chipsets in the
+same way.
+
+Based on a few tests, it seems that a symmetric rx/tx ring size of 2048
+really only makes sense on MT7988, which is capable of 10G ethernet links.
+
+Older chipsets are typically deployed in systems that are more memory
+constrained and don't actually need the larger rings to handle received
+packets.
+
+In order to reduce wasted memory set the ring size based on the SoC to
+the following values:
+- 2048 on MT7988
+- 1024 on MT7986
+- 512 (previous value) on everything else, except:
+- 256 on RT5350 (the oldest supported chipset)

+ PCS
+
+MediaTek's USXGMII can be found in the MT7988 SoC. We need to access
+it in order to configure and monitor the Ethernet SerDes link in
+USXGMII, 10GBase-R and 5GBase-R mode. By including a wrapped
+legacy 1000Base-X/2500Base-X/Cisco SGMII LynxI PCS as well, those
+interface modes are also available.

++description:
++  The MediaTek USXGMII PCS provides physical link control and status
++  for USXGMII, 10GBase-R and 5GBase-R links on the SerDes interfaces
++  provided by the PEXTP PHY.
++  In order to also support legacy 2500Base-X, 1000Base-X and Cisco
++  SGMII an existing mediatek,*-sgmiisys LynxI PCS is wrapped to
++  provide those interfaces modes on the same SerDes interfaces shared
++  with the USXGMII PCS.

+Subject: [PATCH] net: phy: broadcom: update dependency condition
+
+The broadcom PHY driver only has to depend upon PTP_1588_CLOCK_OPTIONAL
+if NETWORK_PHY_TIMESTAMPING is enabled. The PTP functionality is stubbed
+in this case.
+
+Reflect this circumstance in the dependence condition. This allows to
+build the driver as a built-in module even if PTP is built as a module.
+
+This is required to include the broadcom PHY module regardless of the
+built-setting of the PTP subsystem. On ath79 (and probably more)
+targets with Broadcom PHY, Gigabit operation is currently broken as the
+PHY driver is only built as a module in case all kernel-packages are
+built. Due to this circumstance, affected devices fall back to using the
+generic PHY driver.

+
+Add support for SBL state callback in MHI core.
+
+It is required for ath11k MHI devices in order to be able to set QRTR
+instance ID in the SBL state so that QRTR instance ID-s dont conflict in
+case of multiple PCI/MHI cards or AHB + PCI/MHI card.
+Setting QRTR instance ID is only possible in SBL state and there is
+currently no way to ensure that we are in that state, so provide a
+callback that the controller can trigger off.

+Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
+ subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[    1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[    1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[    1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[    1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[    0.157054] missing gpiochip .dev parent pointer
+[    0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").

+Subject: [PATCH 2/2] gpio: gpio-cascade: add generic GPIO cascade
+
+Adds support for building cascades of GPIO lines. That is, it allows
+setups when there is one upstream line and multiple cascaded lines, out
+of which one can be chosen at a time. The status of the upstream line
+can be conveyed to the selected cascaded line or, vice versa, the status
+of the cascaded line can be conveyed to the upstream line.
+
+A multiplexer is being used to select, which cascaded GPIO line is being
+used at any given time.
+
+At the moment only input direction is supported. In future it should be
+possible to add support for output direction, too.

+v7 -> v8:
+ - rearrange members in struct gpio_cascade
+ - cosmetic changes in file header and in one function declaration
+ - added Reviewed-by tags by Linus and Andy
+v6 -> v7:
+ - In Kconfig add info about module name
+ - adhere to new convention that allows lines longer than 80 chars
+ - use dev_probe_err with upstream gpio line too
+ - refactor for cleaner exit of probe function.
+v5 -> v6:
+ - In Kconfig, remove dependency to OF_GPIO and select only MULTIPLEXER
+ - refactor code preferring one-liners
+ - clean up prints, removing them from success-path.
+ - don't explicitly set gpio_chip.of_node as it's done in the GPIO library
+ - use devm_gpiochip_add_data instead of gpiochip_add
+v4 -> v5:
+ - renamed gpio-mux-input -> gpio-cascade. refactored code accordingly
+   here and there and changed to use new bindings and compatible string
+   - ambigious and vague 'pin' was rename to 'upstream_line'
+ - dropped Tested-by and Reviewed-by due to changes in bindings
+ - dropped Reported-by suggested by an automatic bot as it was not really
+   appropriate to begin with
+ - functionally it's the same as v4
+v3 -> v4:
+ - Changed author email
+ - Included Tested-by and Reviewed-by from Drew
+v2 -> v3:
+ - use managed device resources
+ - update Kconfig description
+v1 -> v2:
+ - removed .owner from platform_driver as per test bot's instruction
+ - added MODULE_AUTHOR, MODULE_DESCRIPTION, MODULE_LICENSE
+ - added gpio_mux_input_get_direction as it's recommended for all chips
+ - removed because this is input only chip: gpio_mux_input_set_value
+ - removed because they are not needed for input/output only chips:
+     gpio_mux_input_direction_input
+     gpio_mux_input_direction_output
+ - fixed typo in an error message
+ - added info message about successful registration
+ - removed can_sleep flag as this does not sleep while getting GPIO value
+   like I2C or SPI do
+ - Updated description in Kconfig

+Subject: [PATCH 1/2] nvmem: core: generalize "mac-base" cells handling
+
+Generalize support of "mac-base" nvmem cells and provide a GPL symbol to
+permit also other NVMEM layout driver to parse mac-base cells.
+
+It's VERY COMMON for some specially formatted NVMEM to expose a mac
+address in ASCII format or HEX format hence prevent code duplication by
+exposing a common helper.
+
+Such helper will change the nvmem_info_cell and apply the correct post
+process function to correctly parse the mac address.
+
+Since the API requires OF and is only related to layout, move the
+function in layouts.c to correctly handle non-OF NVMEM.

+Subject: [PATCH 2/2] nvmem: layouts: add support for ascii-env driver
+
+Add support for simple ASCII envirorment driver for NVMEM layouts.
+
+It's very common for devices to store simple text file format in
+partition for environment varibles. The most common pattern is variable
+name, a delimiter and variable value all separated by a new line
+character (\n).
+
+This driver adds support for exporting such data and expose NVMEM cells
+so they can be referenced by other drivers. This driver also supports
+parsing mac-base NVMEM cells to parse ASCII or HEX mac address.

++	  It's very common for devices to store simple text file format in
++	  partition for environment varibles. The most common pattern is variable
++	  name, a delimiter and variable value all separated by a new line
++	  character (\n).
++	  This driver adds support for exporting such data and expose NVMEM cells
++	  so they can be referenced by other drivers. This driver also supports
++	  parsing mac-base NVMEM cells to parse ASCII or HEX mac address.
++
++	  If unsure, say N.

+Subject: libata: add ledtrig support
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain

+Subject: [PATCH] PCI: aardvark: Make main irq_chip structure a static driver
+ structure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+We have already converted others irq_chip structures in this driver in
+this way, but we omitted this one because the .name member is
+dynamically created from device's name, and the name is displayed in
+sysfs, so changing it would break sysfs ABI.
+
+The rationale for changing the name (to "advk-INT") in spite of sysfs
+ABI, and thus allowing to convert to a static structure, is that after
+the other changes we made in this series, the IRQ chip is basically
+something different: it no logner generates ERR and PME interrupts (they
+are generated by emulated bridge's rp_irq_chip).

+Subject: [PATCH] ARM: dts: nxp: imx7d-pico: add cpu-supply nodes
+
+The PICO-IMX7D SoM has the usual power supply configuration using
+output sw1a of PF3000 PMIC, which was defined in downstream derivative
+of linux-imx (see link) in the sources for "Android Things" devkit.
+It is required to support CPU frequency scaling.
+
+Map the respective "cpu-supply" nodes of each core to sw1a of the PMIC.
+
+Enabling them causes cpufreq-dt, and imx-thermal drivers to probe
+successfully, and CPU frequency scaling to function.

+Subject: [PATCH v7] usb: serial: add support for CH348
+
+The CH348 is an USB octo port serial adapter.
+The device multiplexes all 8 ports in the same pair of Bulk endpoints.
+Since there is no public datasheet, unfortunately it remains some magic values

+Date: Wed, 18 Dec 2024 18:33:59 +0000	[thread overview]
+Message-ID: <20241218183401.41687-4-vicentiu.galanopulo@remote-tech.co.uk> (raw)
+In-Reply-To: <20241218183401.41687-1-vicentiu.galanopulo@remote-tech.co.uk>
+
+The output current can be adjusted separately for each channel by 8-bit
+analog (current sink input) and 12-bit digital (PWM) dimming control. The
+LED1202 implements 12 low-side current generators with independent dimming
+control.
+Internal volatile memory allows the user to store up to 8 different patterns,
+each pattern is a particular output configuration in terms of PWM
+duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but
+common to all patterns. Each device tree LED node will have a corresponding
+entry in /sys/class/leds with the label name. The brightness property
+corresponds to the per channel analog dimming, while the patterns[1-8] to the
+PWM dimming control.

+Subject: [PATCH 1/5] leds: leds-st1202: fix NULL pointer access on race
+ condition
+
+st1202_dt_init() calls devm_led_classdev_register_ext() before the
+internal data structures are properly setup, so the leds become visible
+to user space while being partially initialized, leading to a window
+where trying to access them causes a NULL pointer access.
+
+This change moves devm_led_classdev_register_ext() to the last thing to
+happen during initialization to eliminate it.

+
+With the current range specified for the CPU interface there is an
+error message at boot:
+
+GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
+
+Setting irqchip.gicv2_force_probe=1 in bootargs results in:
+
+GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
+GIC: Adjusting CPU interface base to 0x000000001032f000
+GIC: Using split EOI/Deactivate mode
+
+Using the adjusted CPU interface base and 8K size results in only the
+final line remaining and fully working system as well as /proc/interrupts
+showing additional IPI3,4,5,6:
+
+IPI3:         0          0       CPU stop (for crash dump) interrupts
+IPI4:         0          0       Timer broadcast interrupts
+IPI5:         0          0       IRQ work interrupts
+IPI6:         0          0       CPU wake-up interrupts

+Subject: [PATCH] mediatek: mt7623: fix thermal zone
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raising the temperatures for passive and active trips. @VA1DER
+proposed at issue 9396 to remove passive trip. This commit relates to
+his suggestion.
+
+Without this patch. the CPU will be throttled all the way down to 98MHz
+if the temperature rises even a degree above the trip point, and it was
+further discovered that if the internal temperature of the device is
+above the first trip point temperature when it boots then it will start
+in a throttled state and even
+$ echo disabled > /sys/class/thermal/thermal_zone0/mode
+will have no effect.
+
+The patch increases the passive trip point and active cooling map. The
+throttling temperature will then be at 77°C and 82°C, which is still a
+low enough temperature for ARM devices to not be in the real danger
+zone, and gives some operational headroom.

+Subject: [PATCH] mediatek mt7622: fix 300mhz typo in dts
+
+The lowest frequency should be 300MHz, since that is the label
+assigned to the OPP in the mt7622.dtsi device tree, while there is one
+missing zero in the actual value.
+
+To be clear, the lowest frequency should be 300MHz instead of 30MHz.
+
+As mentioned @dangowrt on the OpenWrt forum there is no benefit in
+leaving 30MHz as the lowest frequency.

+Subject: [PATCH net-next 2/2] net: ethernet: mtk_wed: move cpuboot in a
+ dedicated dts node
+
+Since the cpuboot memory region is not part of the RAM SoC, move cpuboot
+in a deidicated syscon node.
+This patch helps to keep backward-compatibility with older version of
+uboot codebase where we have a limit of 8 reserved-memory dts child
+nodes.
+Keep backward-compatibility with older dts version where cpuboot was
+defined as reserved-memory child node.

+Subject: [PATCH] arm64: dts: ipq8074: add reserved memory nodes
+
+IPQ8074 has multiple reserved memory ranges, if they are not defined
+then weird things tend to happen, board hangs and resets when PCI or
+WLAN is used etc.
+
+So, to avoid all of that add the reserved memory nodes from the downstream
+5.4 kernel from QCA.
+This is their default layout meant for devices with 1GB of RAM, but
+devices with lower ammounts can override the Q6 node.

+Subject: [PATCH] remoteproc: qcom: Add support for split q6 + m3 wlan firmware
+
+IPQ8074 supports split firmware for q6 and m3 as well.
+So add support for loading the m3 firmware before q6.
+Now the drivers works fine for both split and unified
+firmwares.

+Subject: [PATCH 1/1] mtd: rawnand: add support for TH58NYG3S0HBAI4 NAND flash
+
+The Toshiba TH58NYG3S0HBAI4 is detected with 128 byte OOB while the flash
+has 256 bytes OOB. Since it is not an ONFI compliant NAND, the model name
+cannot be read from anywhere, add a static NAND ID entry to correct this.
+
+However, the NAND ID of this flash is inconsistent with the datasheet.
+The actual NAND ID is only 4 ID bytes, the last ID byte is missing.
+
+Datasheet available at (the ID table is on page 50):
+https://europe.kioxia.com/content/dam/kioxia/newidr/productinfo/datasheet/201910/DST_TH58NYG3S0HBAI4-TDE_EN_31565.pdf
+
+Datasheet NAND ID: {0x98, 0xa3, 0x91, 0x26, 0x76}
+Actual NAND ID: {0x98, 0xa3, 0x91, 0x26}
+
+It seems that this flash may be counterfeit, but another Toshiba flash
+also has the same problem. Maybe the driver has a bug, or some Toshiba
+nand flash is like this. Anyway, add a static NAND ID entry with only
+4 ID bytes as a hack to make sure it works.
+
+Tested on Arcadyan AW1000 flashed with OpenWrt.

+Some older IPQ60xx SoC series boards ship with TrustZone/QSEE firmware
+older than TZ.WNS.5.1-00084 which will advertise OSI[1] but are broken
+and trying to use OSI will cause the board to hang until WDT kicks in.

+Subject: [PATCH] clk: qcom: ipq6018: workaround networking clock parenting
+
+Currently, networking clocks are only looked up by fw_name however,
+these are registered and setup by SSDK and are not available to the
+GCC driver at all, so work around that by providing a global name
+fallback.
+
+While we are here, provide global fallback for bias_pll_cc_clk and
+bias_pll_nss_noc_clk as well as these are fixed clocks also not available
+to the driver.

+
+On IPQ6018 this string ends up being sent to RPM when remoteproc stops
+(on crash or rmmod ath11k). "q6wcss" is not a valid name (not found by
+`strings` in rpm.mbn), so this causes RPM do 'something' (presumably crash)
+causing a system reboot followed by hang in XBL, with no WDT running.
+Let's change ssr_name to a more sensible 'wcnss', that does not cause such
+issues.

+Subject: [PATCH 11/19] soc: qcom: fix smp2p ack on ipq6018
+
+IPQ6018 seem to need different ack mechanism for smp2p messaging. This
+fixes q6v5_wcss remoteproc firmware reloading. Without this first load
+is OK, but subsequent loads would hang and fail to complete.

+Subject: [PATCH v3 1/1] x86: Support APU5 in PCEngines platform driver
+To: platform-driver-x86@vger.kernel.org, linux-x86_64@vger.kernel.org
+Cc: Ed Wildgoose <lists@wildgooses.com>, Andres Salomon <dilinger@queued.net>, Andreas Eberlein <foodeas@aeberlein.de>, Paul Spooren <paul@spooren.de>
+
+PCEngines make a number of SBC. APU5 has 5 mpcie slots + MSATA.
+It also has support for 3x LTE modems with 6x SIM slots (pairs with a
+SIM switch device). Each mpcie slot for modems has a reset GPIO
+
+To ensure that the naming is sane between APU2-6 the GPIOS are
+renamed to be modem1-reset, modem2-reset, etc. This is significant
+because the slots that can be reset change between APU2 and APU3/4
+
+GPIO for simswap is moved to the end of the list as it could be dropped
+for APU2 boards (but causes no harm to leave it in, hardware could be
+added to a future rev of the board).
+
+Structure of the GPIOs for APU5 is extremely similar to APU2-4, but
+many lines are moved around and there are simply more
+modems/resets/sim-swap lines to breakout.
+
+Also added APU6, which is essentially APU4 with a different ethernet
+interface and SFP cage on eth0.
+
+Revision history:
+
+v1: originally titled, "apu6: add apu6 variation to apu2 driver family"
+this dealt only with detecting the APUv6, which is otherwise identical
+to the v4 excepting the SFP cage on eth0.
+
+v2: at Ed's request, merged with his previous pull-request titled
+"x86: Support APU5 in PCEngines platform driver", and some cleanup
+to that changeset (including dropping the table "apu5_driver_data"
+which did not have a defined type "struct apu_driver_data"), but got
+mistitled when the Subject of that commit got accidentally dropped.
+
+v3: retitled to match Ed's previous pull-request.

+Subject: [PATCH] firewall4: add fullcone support
+
+fullcone is drop-in replacement of masq for non-udp traffic
+
+add runtime fullcone rule check, disable it globally if fullcone expr is
+invalid
+
+defaults.fullcone is the global switch, while zone.fullcone4 and
+zone.fullcone6 are switches for IPv4 and IPv6 respectively, most
+IPv6 traffic do NOT need this FullCone NAT functionality.

+Subject: [PATCH] dts: Add hogs for RP1 GPIO 46/48 on CM5
+
+On Pi5 5, GPIOs 46/48 are made available on the 'CAM/DISP 1' connector as
+'CD1_IO0_MICCLK'/'CD1_IO1_MICDAT1'. These GPIOs are not connected on
+CM5.
+
+Add hogs for GPIO 46/48 on CM5 to prevent camera drivers from
+inadvertently using them when connected to 'CAM/DISP 1'
+
+Signed-off-by: Richard Oliver <richard.oliver@raspberrypi.com>

+Subject: [PATCH 01/18] net-tcp_bbr: broaden app-limited rate sample detection
+
+This commit is a bug fix for the Linux TCP app-limited
+(application-limited) logic that is used for collecting rate
+(bandwidth) samples.
+
+Previously the app-limited logic only looked for "bubbles" of
+silence in between application writes, by checking at the start
+of each sendmsg. But "bubbles" of silence can also happen before
+retransmits: e.g. bubbles can happen between an application write
+and a retransmit, or between two retransmits.
+
+Retransmits are triggered by ACKs or timers. So this commit checks
+for bubbles of app-limited silence upon ACKs or timers.
+
+Why does this commit check for app-limited state at the start of
+ACKs and timer handling? Because at that point we know whether
+inflight was fully using the cwnd.  During processing the ACK or
+timer event we often change the cwnd; after changing the cwnd we
+can't know whether inflight was fully using the old cwnd.

+Subject: [PATCH 02/18] net-tcp_bbr: v2: shrink delivered_mstamp,
+ first_tx_mstamp to u32 to free up 8 bytes
+
+Free up some space for tracking inflight and losses for each
+bw sample, in upcoming commits.
+
+These timestamps are in microseconds, and are now stored in 32
+bits. So they can only hold time intervals up to roughly 2^12 = 4096
+seconds.  But Linux TCP RTT and RTO tracking has the same 32-bit
+microsecond implementation approach and resulting deployment
+limitations. So this is not introducing a new limit. And these should
+not be a limitation for the foreseeable future.

+Subject: [PATCH 03/18] net-tcp_bbr: v2: snapshot packets in flight at transmit
+ time and pass in rate_sample
+
+CC algorithms may want to snapshot the number of packets in flight at
+transmit time and pass in rate_sample, to understand the relationship
+between inflight and losses or ECN signals, to try to find the highest
+inflight value that has acceptable levels of loss/ECN marking.
+
+We split out the code to set an skb's tx.in_flight field into its own
+function, so that this code can be used for the TCP_REPAIR "fake send"
+code path that inserts skbs into the rtx queue without sending them.

+Subject: [PATCH 06/18] net-tcp_bbr: v2: introduce ca_ops->skb_marked_lost() CC
+ module callback API
+
+For connections experiencing reordering, RACK can mark packets lost
+long after we receive the SACKs/ACKs hinting that the packets were
+actually lost.
+
+This means that CC modules cannot easily learn the volume of inflight
+data at which packet loss happens by looking at the current inflight
+or even the packets in flight when the most recently SACKed packet was
+sent. To learn this, CC modules need to know how many packets were in
+flight at the time lost packets were sent. This new callback, combined
+with TCP_SKB_CB(skb)->tx.in_flight, allows them to learn this.
+
+This also provides a consistent callback that is invoked whether
+packets are marked lost upon ACK processing, using the RACK reordering
+timer, or at RTO time.

+Subject: [PATCH 07/18] net-tcp_bbr: v2: adjust skb tx.in_flight upon merge in
+ tcp_shifted_skb()
+
+When tcp_shifted_skb() updates state as adjacent SACKed skbs are
+coalesced, previously the tx.in_flight was not adjusted, so we could
+get contradictory state where the skb's recorded pcount was bigger
+than the tx.in_flight (the number of segments that were in_flight
+after sending the skb).
+
+Normally have a SACKed skb with contradictory pcount/tx.in_flight
+would not matter. However, with SACK reneging, the SACKed bit is
+removed, and an skb once again becomes eligible for retransmitting,
+fragmenting, SACKing, etc. Packetdrill testing verified the following
+sequence is possible in a kernel that does not have this commit:
+
+ - skb N is SACKed
+ - skb N+1 is SACKed and combined with skb N using tcp_shifted_skb()
+   - tcp_shifted_skb() will increase the pcount of prev,
+     but leave tx.in_flight as-is
+   - so prev skb can have pcount > tx.in_flight
+ - RTO, tcp_timeout_mark_lost(), detect reneg,
+   remove "SACKed" bit, mark skb N as lost
+   - find pcount of skb N is greater than its tx.in_flight
+
+I suspect this issue iw what caused the bbr2_inflight_hi_from_lost_skb():
+  WARN_ON_ONCE(inflight_prev < 0)
+to fire in production machines using bbr2.

+ tcp_fragment()
+
+When we fragment an skb that has already been sent, we need to update
+the tx.in_flight for the first skb in the resulting pair ("buff").
+
+Because we were not updating the tx.in_flight, the tx.in_flight value
+was inconsistent with the pcount of the "buff" skb (tx.in_flight would
+be too high). That meant that if the "buff" skb was lost, then
+bbr2_inflight_hi_from_lost_skb() would calculate an inflight_hi value
+that is too high. This could result in longer queues and higher packet
+loss.
+
+Packetdrill testing verified that without this commit, when the second
+half of an skb is SACKed and then later the first half of that skb is
+marked lost, the calculated inflight_hi was incorrect.

+
+Add a a new ca opts flag TCP_CONG_WANTS_CE_EVENTS that allows a
+congestion control module to receive CE events.
+
+Currently congestion control modules have to set the TCP_CONG_NEEDS_ECN
+bit in opts flag to receive CE events but this may incur changes in ECN
+behavior elsewhere. This patch adds a new bit TCP_CONG_WANTS_CE_EVENTS
+that allows congestion control modules to receive CE events
+independently of TCP_CONG_NEEDS_ECN.

+Subject: [PATCH 10/18] net-tcp: re-generalize TSO sizing in TCP CC module API
+
+Reorganize the API for CC modules so that the CC module once again
+gets complete control of the TSO sizing decision. This is how the API
+was set up around 2016 and the initial BBRv1 upstreaming. Later Eric
+Dumazet simplified it. But with wider testing it now seems that to
+avoid CPU regressions BBR needs to have a different TSO sizing
+function.
+
+This is necessary to handle cases where there are many flows
+bottlenecked on the sender host's NIC, in which case BBR's pacing rate
+is much lower than CUBIC/Reno/DCTCP's. Why does this happen? Because
+BBR's pacing rate adapts to the low bandwidth share each flow sees. By
+contrast, CUBIC/Reno/DCTCP see no loss or ECN, so they grow a very
+large cwnd, and thus large pacing rate and large TSO burst size.

+Subject: [PATCH 13/18] net-tcp_bbr: v2: inform CC module of losses repaired by
+ TLP probe
+
+Before this commit, when there is a packet loss that creates a sequence
+hole that is filled by a TLP loss probe, then tcp_process_tlp_ack()
+only informs the congestion control (CC) module via a back-to-back entry
+and exit of CWR. But some congestion control modules (e.g. BBR) do not
+respond to CWR events.
+
+This commit adds a new CA event with which the core TCP stack notifies
+the CC module when a loss is repaired by a TLP. This will allow CC
+modules that do not use the CWR mechanism to have a custom handler for
+such TLP recoveries.

+
+Define and implement a new per-route feature, RTAX_FEATURE_ECN_LOW.
+
+This feature indicates that the given destination network is a
+low-latency ECN environment, meaning both that ECN CE marks are
+applied by the network using a low-latency marking threshold and also
+that TCP endpoints provide precise per-data-segment ECN feedback in
+ACKs (where the ACK ECE flag echoes the received CE status of all
+newly-acknowledged data segments). This feature indication can be used
+by congestion control algorithms to decide how to interpret ECN
+signals over the given destination network.
+
+This feature is appropriate for datacenter-style ECN marking, such as
+the ECN marking approach expected by DCTCP or BBR congestion control
+modules.

+Subject: [PATCH 16/18] net-tcp_bbr: v3: update TCP "bbr" congestion control
+ module to BBRv3
+
+BBR v3 is an enhacement to the BBR v1 algorithm. It's designed to aim for lower
+queues, lower loss, and better Reno/CUBIC coexistence than BBR v1.
+
+BBR v3 maintains the core of BBR v1: an explicit model of the network
+path that is two-dimensional, adapting to estimate the (a) maximum
+available bandwidth and (b) maximum safe volume of data a flow can
+keep in-flight in the network. It maintains the estimated BDP as a
+core guide for estimating an appropriate level of in-flight data.
+
+BBR v3 makes several key enhancements:
+
+o Its bandwidth-probing time scale is adapted, within bounds, to allow improved
+coexistence with Reno and CUBIC. The bandwidth-probing time scale is (a)
+extended dynamically based on estimated BDP to improve coexistence with
+Reno/CUBIC; (b) bounded by an interactive wall-clock time-scale to be more
+scalable and responsive than Reno and CUBIC.
+
+o Rather than being largely agnostic to loss and ECN marks, it explicitly uses
+loss and (DCTCP-style) ECN signals to maintain its model.
+
+o It aims for lower losses than v1 by adjusting its model to attempt to stay
+within loss rate and ECN mark rate bounds (loss_thresh and ecn_thresh,
+respectively).
+
+o It adapts to loss/ECN signals even when the application is running out of
+data ("application-limited"), in case the "application-limited" flow is also
+"network-limited" (the bw and/or inflight available to this flow is lower than
+previously estimated when the flow ran out of data).
+
+o It has a three-part model: the model explicit three tracks operating points,
+where an operating point is a tuple: (bandwidth, inflight). The three operating
+points are:
+
+  o latest:        the latest measurement from the current round trip
+  o upper bound:   robust, optimistic, long-term upper bound
+  o lower bound:   robust, conservative, short-term lower bound
+
+These are stored in the following state variables:
+
+  o latest:  bw_latest, inflight_latest
+  o lo:      bw_lo,     inflight_lo
+  o hi:      bw_hi[2],  inflight_hi
+
+To gain intuition about the meaning of the three operating points, it
+may help to consider the analogs in CUBIC, which has a somewhat
+analogous three-part model used by its probing state machine:
+
+  BBR param     CUBIC param
+  -----------   -------------
+  latest     ~  cwnd
+  lo         ~  ssthresh
+  hi         ~  last_max_cwnd
+
+The analogy is only a loose one, though, since the BBR operating
+points are calculated differently, and are 2-dimensional (bw,inflight)
+rather than CUBIC's one-dimensional notion of operating point
+(inflight).
+
+o It uses the three-part model to adapt the magnitude of its bandwidth
+to match the estimated space available in the buffer, rather than (as
+in BBR v1) assuming that it was always acceptable to place 0.25*BDP in
+the bottleneck buffer when probing (commodity datacenter switches
+commonly do not have that much buffer for WAN flows). When BBR v3
+estimates it hit a buffer limit during probing, its bandwidth probing
+then starts gently in case little space is still available in the
+buffer, and the accelerates, slowly at first and then rapidly if it
+can grow inflight without seeing congestion signals. In such cases,
+probing is bounded by inflight_hi + inflight_probe, where
+inflight_probe grows as: [0, 1, 2, 4, 8, 16,...]. This allows BBR to
+keep losses low and bounded if a bottleneck remains congested, while
+rapidly/scalably utilizing free bandwidth when it becomes available.
+
+o It has a slightly revised state machine, to achieve the goals above.
+    BBR_BW_PROBE_UP:    pushes up inflight to probe for bw/vol
+    BBR_BW_PROBE_DOWN:  drain excess inflight from the queue
+    BBR_BW_PROBE_CRUISE: use pipe, w/ headroom in queue/pipe
+    BBR_BW_PROBE_REFILL: try refill the pipe again to 100%, leaving queue empty
+
+o The estimated BDP: BBR v3 continues to maintain an estimate of the
+path's two-way propagation delay, by tracking a windowed min_rtt, and
+coordinating (on an as-ndeeded basis) to try to expose the two-way
+propagation delay by draining the bottleneck queue.
+
+BBR v3 continues to use its min_rtt and (currently-applicable) bandwidth
+estimate to estimate the current bandwidth-delay product. The estimated BDP
+still provides one important guideline for bounding inflight data. However,
+because any min-filtered RTT and max-filtered bw inherently tend to both
+overestimate, the estimated BDP is often too high; in this case loss or ECN
+marks can ensue, in which case BBR v3 adjusts inflight_hi and inflight_lo to
+adapt its sending rate and inflight down to match the available capacity of the
+path.
+
+o Space: Note that ICSK_CA_PRIV_SIZE increased. This is because BBR v3
+requires more space. Note that much of the space is due to support for
+per-socket parameterization and debugging in this release for research
+and debugging. With that state removed, the full "struct bbr" is 140
+bytes, or 144 with padding. This is an increase of 40 bytes over the
+existing ca_priv space.
+
+o Code: BBR v3 reuses many pieces from BBR v1. But it omits the following
+  significant pieces:
+
+  o "packet conservation" (bbr_set_cwnd_to_recover_or_restore(),
+    bbr_can_grow_inflight())
+  o long-term bandwidth estimator ("policer mode")
+
+  The code layout tries to keep BBR v3 code near the bottom of the
+  file, so that v1-applicable code in the top does not accidentally
+  refer to v3 code.
+
+o Docs:
+  See the following docs for more details and diagrams decsribing the BBR v3
+  algorithm:
+    https://datatracker.ietf.org/meeting/104/materials/slides-104-iccrg-an-update-on-bbr-00
+    https://datatracker.ietf.org/meeting/102/materials/slides-102-iccrg-an-update-on-bbr-work-at-google-00
+
+o Internal notes:
+  For this upstream rebase, Neal started from:
+    git show fed518041ac6:net/ipv4/tcp_bbr.c > net/ipv4/tcp_bbr.c
+  then removed dev instrumentation (dynamic get/set for parameters)
+  and code that was only used by BBRv1

+- * BBR congestion control computes the sending rate based on the delivery
+- * rate (throughput) estimated from ACKs. In a nutshell:
++ * BBR is a model-based congestion control algorithm that aims for low queues,
++ * low loss, and (bounded) Reno/CUBIC coexistence. To maintain a model of the
++ * network path, it uses measurements of bandwidth and RTT, as well as (if they
++ * occur) packet loss and/or shallow-threshold ECN signals. Note that although
++ * it can use ECN or loss signals explicitly, it does not require either; it
++ * can bound its in-flight data based on its estimate of the BDP.
+  *
+- *   On each ACK, update our model of the network path:
+- *      bottleneck_bandwidth = windowed_max(delivered / elapsed, 10 round trips)
+- *      min_rtt = windowed_min(rtt, 10 seconds)
+- *   pacing_rate = pacing_gain * bottleneck_bandwidth
+- *   cwnd = max(cwnd_gain * bottleneck_bandwidth * min_rtt, 4)
+- *
+- * The core algorithm does not react directly to packet losses or delays,
+- * although BBR may adjust the size of next send per ACK when loss is
+- * observed, or adjust the sending rate if it estimates there is a
+- * traffic policer, in order to keep the drop rate reasonable.
++ * The model has both higher and lower bounds for the operating range:
++ *   lo: bw_lo, inflight_lo: conservative short-term lower bound
++ *   hi: bw_hi, inflight_hi: robust long-term upper bound
++ * The bandwidth-probing time scale is (a) extended dynamically based on
++ * estimated BDP to improve coexistence with Reno/CUBIC; (b) bounded by

+Subject: [PATCH 17/18] net-tcp_bbr: v3: ensure ECN-enabled BBR flows set ECT
+ on retransmits
+
+Adds a new flag TCP_ECN_ECT_PERMANENT that is used by CCAs to
+indicate that retransmitted packets and pure ACKs must have the
+ECT bit set. This is necessary for BBR, which when using
+ECN expects ECT to be set even on retransmitted packets and ACKs.
+
+Previous to this addition of TCP_ECN_ECT_PERMANENT, CCAs which can use
+ECN but don't "need" it did not have a way to indicate that ECT should
+be set on retransmissions/ACKs.

+Add a new helper mptcp_sched_data_set_contexts() to set the subflow
+pointers array in struct mptcp_sched_data. Add a new helper
+mptcp_subflow_ctx_by_pos() to get the given pos subflow from the
+contexts array in struct mptcp_sched_data. They will be invoked by
+the BPF schedulers to export the subflow pointers to the BPF contexts.

+Subject: [PATCH] bpf: Add bpf_mptcp_sched_ops
+
+This patch implements a new struct bpf_struct_ops: bpf_mptcp_sched_ops.
+Register and unregister the bpf scheduler in .reg and .unreg.
+
+Add write access for the scheduled flag of struct mptcp_subflow_context
+in .btf_struct_access.
+
+This MPTCP BPF scheduler implementation is similar to BPF TCP CC. And
+net/ipv4/bpf_tcp_ca.c is a frame of reference for this patch.

+Subject: [PATCH] bpf: Export more bpf_burst related functions
+
+sk_stream_memory_free() and tcp_rtx_and_write_queues_empty() are needed
+to export into the BPF context for bpf_burst scheduler. But these two
+functions are inline ones. So this patch added two wrappers for them,
+and export the wrappers in the BPF context.
+
+Add more bpf_burst related functions into bpf_mptcp_sched_kfunc_set to make
+sure these helpers can be accessed from the BPF context.

+Subject: [PATCH] clk: ipq8074: fix gcc_blsp1_ahb_clk properties
+
+All the voting enabled clocks does not support the enable
+from CBCR register. So, updated gcc_blsp1_ahb_clk enable
+register and mask to enable bit in APCS_CLOCK_BRANCH_ENA_VOTE.
+
+Also, the voting controlled clocks are shared among multiple
+components like APSS, RPM, NSS, TZ, etc. So, turning the
+voting off from APSS does not make the clock off if it has
+been voted from another component. Added the flag
+BRANCH_HALT_VOTED in order to skip checking the clock
+disable status.
+
+This change is referred from the below commits,
+1. 246b4fb3af9bd65d8af794aac2f0e7b1ed9cc2dd
+2. c8374157d5ae91d3b3e0d513d62808a798b32d3a

+
+These events should be called only when the route table is
+changed by the userspace. So, we should call them in the
+ioctl and the netlink message handler function.

+It looks like commit 0857d6f8c759 ("ipv6: When forwarding count rx stats
+on the orig netdev") tries to determine the right netdev to account the
+rx stats, but in this particular case it's failing and the netdev is
+NULL.
+
+Fallback to the previous method of determining the netdev interface (via
+skb->dev) to account the rx stats when the orig netdev can't be
+determined.
+
+Fixes: 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orig netdev")

-# procd API:
-#
-# procd_open_service(name, [script]):
-#   Initialize a new procd command message containing a service with one or more instances
-#
-# procd_close_service()
-#   Send the command message for the service
-#
-# procd_open_instance([name]):
-#   Add an instance to the service described by the previous procd_open_service call
-#
-# procd_set_param(type, [value...])
-#   Available types:
-#     command: command line (array).
-#     respawn info: array with 3 values $fail_threshold $restart_timeout $max_fail
-#     env: environment variable (passed to the process)
-#     data: arbitrary name/value pairs for detecting config changes (table)
-#     file: configuration files (array)
-#     netdev: bound network device (detects ifindex changes)
-#     limits: resource limits (passed to the process)
-#     user: $username to run service as
-#     group: $groupname to run service as
-#     pidfile: file name to write pid into
-#     stdout: boolean whether to redirect commands stdout to syslog (default: 0)
-#     stderr: boolean whether to redirect commands stderr to syslog (default: 0)
-#     facility: syslog facility used when logging to syslog (default: daemon)
-#
-#   No space separation is done for arrays/tables - use one function argument per command line argument
-#
-# procd_close_instance():
-#   Complete the instance being prepared
-#
-# procd_running(service, [instance]):
-#   Checks if service/instance is currently running
-#
-# procd_kill(service, [instance]):
-#   Kill a service instance (or all instances)
-#
-# procd_send_signal(service, [instance], [signal])
-#   Send a signal to a service instance (or all instances)
