- them early
-
-The old arch-specific IRQ macros included a dsb to ensure the
-write to clear the mailbox interrupt completed before returning
-from the interrupt. The BCM2836 irqchip driver needs the same
-precaution to avoid spurious interrupts.
-
-Spurious interrupts are still possible for other reasons,
-though, so trap them early.

-Subject: [PATCH 011/432] spi-bcm2835: Support pin groups other than 7-11
-
-The spi-bcm2835 driver automatically uses GPIO chip-selects due to
-some unreliability of the native ones. In doing so it chooses the
-same pins as the native chip-selects would use, but the existing
-code always uses pins 7 and 8, wherever the SPI function is mapped.
-
-Search the pinctrl group assigned to the driver for pins that
-correspond to native chip-selects, and use those for GPIO chip-
-selects.

-Subject: [PATCH 025/432] 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.

- critical.
-
-These divide off of PLLD_PER and are used for the ethernet and wifi
-PHYs source PLLs.  Neither of them is currently represented by a phy
-device that would grab the clock for us.
-
-This keeps other drivers from killing the networking PHYs when they
-disable their own clocks and trigger PLLD_PER's refcount going to 0.
-
-v2: Skip marking as critical if they aren't on at boot.

-Since this situation is expected, reduce the dmesg level to

-Subject: [PATCH 028/432] 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.

-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:

-Subject: [PATCH 032/432] 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.

-Subject: [PATCH 042/432] Speed up console framebuffer imageblit function
-
-Especially on platforms with a slower CPU but a relatively high
-framebuffer fill bandwidth, like current ARM devices, the existing
-console monochrome imageblit function used to draw console text is
-suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
-code is quite general and can deal with several pixel depths. By creating
-special case functions for 16bpp and 32bpp, by far the most common pixel
-formats used on modern systems, a significant speed-up is attained
-which can be readily felt on ARM-based devices like the Raspberry Pi
-and the Allwinner platform, but should help any platform using the
-fb layer.
-
-The special case functions allow constant folding, eliminating a number
-of instructions including divide operations, and allow the use of an
-unrolled loop, eliminating instructions with a variable shift size,
-reducing source memory access instructions, and eliminating excessive
-branching. These unrolled loops also allow much better code optimization
-by the C compiler. The code that selects which optimized variant is used
-is also simplified, eliminating integer divide instructions.
-
-The speed-up, measured by timing 'cat file.txt' in the console, varies
-between 40% and 70%, when testing on the Raspberry Pi and Allwinner
-ARM-based platforms, depending on font size and the pixel depth, with
-the greater benefit for 32bpp.

-
-Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
-chancnt is already filled by dma_async_device_register, which uses the channel

-
-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.

-  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.
-

-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,
-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.
-
-Fixes https://github.com/raspberrypi/linux/issues/2056

-+* BCM2835 SMI NAND flash
-+
-+This driver is a shim between the BCM2835 SMI driver (SMI is a peripheral for
-+talking to parallel register interfaces) and Linux's MTD layer.
-+
-+Required properties:
-+- compatible: "brcm,bcm2835-smi-nand"
-+- status: "okay"
-+
-+Optional properties:
-+- partition@n, where n is an integer from a consecutive sequence starting at 0
-+	- Difficult to store partition table on NAND device - normally put it
-+	in the source code, kernel bootparams, or device tree (the best way!)
-+	- Sub-properties:
-+		- label: the partition name, as shown by mtdinfo /dev/mtd*
-+		- reg: the size and offset of this partition.
-+		- (optional) read-only: an empty property flagging as read only
-+
-+Example:
-+
-+nand: flash@0 {
-+	compatible = "brcm,bcm2835-smi-nand";
-+	status = "okay";
-+
-+	partition@0 {
-+		label = "stage2";
-+		// 128k
-+		reg = <0 0x20000>;
-+		read-only;
-+	};
-+	partition@1 {
-+		label = "firmware";
-+		// 16M
-+		reg = <0x20000 0x1000000>;
-+		read-only;
-+	};
-+	partition@2 {
-+		label = "root";
-+		// 2G
-+		reg = <0x1020000 0x80000000>;
-+	};

-Subject: [PATCH 053/432] 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.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-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 056/432] scripts: Add mkknlimg and knlinfo scripts from tools
- repo
-
-The Raspberry Pi firmware looks for a trailer on the kernel image to
-determine whether it was compiled with Device Tree support enabled.
-If the firmware finds a kernel without this trailer, or which has a
-trailer indicating that it isn't DT-capable, it disables DT support
-and reverts to using ATAGs.
-
-The mkknlimg utility adds that trailer, having first analysed the
-image to look for signs of DT support and the kernel version string.
-
-knlinfo displays the contents of the trailer in the given kernel image.
-
-scripts/mkknlimg: Add support for ARCH_BCM2835
-
-Add a new trailer field indicating whether this is an ARCH_BCM2835
-build, as opposed to MACH_BCM2708/9. If the loader finds this flag
-is set it changes the default base dtb file name from bcm270x...
-to bcm283y...
-
-Also update knlinfo to show the status of the field.
-
-scripts/mkknlimg: Improve ARCH_BCM2835 detection
-
-The board support code contains sufficient strings to be able to
-distinguish 2708 vs. 2835 builds, so remove the check for
-bcm2835-pm-wdt which could exist in either.
-
-Also, since the canned configuration is no longer built in (it's
-a module), remove the config string checking.
-
-See: https://github.com/raspberrypi/linux/issues/1157
-
-scripts: Multi-platform support for mkknlimg and knlinfo
-
-The firmware uses tags in the kernel trailer to choose which dtb file
-to load. Current firmware loads bcm2835-*.dtb if the '283x' tag is true,
-otherwise it loads bcm270*.dtb. This scheme breaks if an image supports
-multiple platforms.
-
-This patch adds '270X' and '283X' tags to indicate support for RPi and
-upstream platforms, respectively. '283x' (note lower case 'x') is left
-for old firmware, and is only set if the image only supports upstream
-builds.
-
-scripts/mkknlimg: Append a trailer for all input
-
-Now that the firmware assumes an unsigned kernel is DT-capable, it is
-helpful to be able to mark a kernel as being non-DT-capable.

-scripts/knlinfo: Decode DDTK atom
-
-Show the DDTK atom as being a boolean.

-
-mkknlimg: Retain downstream-kernel detection
-
-With the death of ARCH_BCM2708 and ARCH_BCM2709, a new way is needed to
-determine if this is a "downstream" build that wants the firmware to
-load a bcm27xx .dtb. The vc_cma driver is used downstream but not
-upstream, making vc_cma_init a suitable predicate symbol.
-
-mkknlimg: Find some more downstream-only strings
-
-See: https://github.com/raspberrypi/linux/issues/1920
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.org>
-
-scripts: Update mkknlimg, just in case
-
-With the removal of the vc_cma driver, mkknlimg lost an indication that
-the user had built a downstream kernel. Update the script, adding a few
-more key strings, in case it is still being used.
-
-Note that mkknlimg is now deprecated, except to tag kernels as upstream
-(283x), and thus requiring upstream DTBs.

-Subject: [PATCH 058/432] BCM270x_DT: Add pwr_led, and the required "input"
- trigger
-
-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 063/432] 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.
