Subject: [PATCH] rockchip: rk3328: add compatible to NanoPi R2S ethernet PHY
This adds the compatible property to the NanoPi R2S ethernet PHY node.
Otherwise, the PHY might not be probed, as the PHY ID reads all 0xff
when it is still in reset.

Subject: [PATCH] thermal/drivers/rockchip_thermal: Allow more resets for tsadc

The tsadc node in rk356x.dtsi has more resets then currently supported
by the rockchip_thermal.c driver, so use
devm_reset_control_array_get() to reset them all.

Subject: [PATCH] net: stmmac: Add GFP_DMA32 for rx buffers if no 64 capability
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: move rk3568 dtsi to rk356x dtsi
In preparation for separating the rk3568 and rk3566 device trees, move
the base rk3568 dtsi to rk356x dtsi.
This will allow us to strip out the rk3568 specific nodes.

Subject: [PATCH] arm64: dts: rockchip: split rk3568 device tree
In preparation for the rk3566 inclusion, split apart the rk3568 specific
nodes into a separate device tree.
This allows us to create the rk3566 device tree without deleting nodes.

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.

Subject: [PATCH] arm64: dts: rockchip: Add i2s1 on rk356x
This adds the necessary device tree node on rk3566 and rk3568
to enable the I2S1 TDM audio controller.
I2S0 has not been added, as it is connected to HDMI and there is
no way to test that it's working without a functioning video
clock (read: VOP2 driver).

Subject: [PATCH] arm64: dts: rockchip: fix resets in tsadc node for rk356x
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.

New Rockchip devices have the usb phy nodes as standalone devices.
These nodes have register nodes with #address_cells = 2, but only use 32
bit addresses.
Adjust the driver to check if the returned address is "0", and adjust
the index in that case.

Subject: [PATCH] arm64: dts: rockchip: rename and sort the rk356x usb2 phy
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: Support setting f_min from host drivers
Host drivers may not be able to support frequencies as low as dw-mmc
supports. Unfortunately f_min isn't available when the drv_data->init
function is called, as the mmc_host struct hasn't been set up yet.
Support the host drivers saving the requested minimum frequency, so we
can later set f_min when it is available.

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] soc: rockchip: set dwc3 clock for rk3566
The rk3566 dwc3 otg port clock is unavailable at boot, as it defaults to
the combophy as the clock source. As combophy0 doesn't exist on rk3566,
we need to set the clock source to the usb2 phy instead.
Add handling to the grf driver to handle this on boot.

Date: Fri, 22 Apr 2022 09:28:39 +0200
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 yt8531s gigabit
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] net: phy: Add driver for Motorcomm yt8531 gigabit ethernet
phy
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
verified the driver on AM335x platform with yt8531 board. On the
board, yt8531 gigabit ethernet phy works in utp mode, RGMII
interface, supports 1000M/100M/10M speeds, and wol(magic package).

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.

Subject: [PATCH] arm64: dts: rockchip: rk356x: Fix PCIe register and
range mappings
The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.

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.
