+From eef200f75c4a6f6701f1693f8f59ab2c83d1abcd Mon Sep 17 00:00:00 2001
+From: popcornmix <popcornmix@gmail.com>

+Subject: [PATCH 002/121] Add bcm2708_gpio driver
+
+Signed-off-by: popcornmix <popcornmix@gmail.com>
+
+bcm2708: Add extension to configure internal pulls
+
+The bcm2708 gpio controller supports internal pulls to be used as pull-up,
+pull-down or being entirely disabled. As it can be useful for a driver to
+change the pull configuration from it's default pull-down state, add an
+extension which allows configuring the pull per gpio.
+
+Signed-off-by: Julian Scheel <julian@jusst.de>
+
+bcm2708-gpio: Revert the use of pinctrl_request_gpio
+
+In non-DT systems, pinctrl_request_gpio always fails causing
+"requests probe deferral" messages. In DT systems, it isn't useful
+because the reference counting is independent of the normal pinctrl
+pin reservations.
+
+gpio: Only clear the currently occurring interrupt. Avoids losing interrupts
+
+See: linux #760
+
+bcm2708_gpio: Avoid calling irq_unmask for all interrupts
+
+When setting up the interrupts, specify that the handle_simple_irq
+handler should be used. This leaves interrupt acknowledgement to
+the caller, and prevents irq_unmask from being called for all
+interrupts.
+
+Issue: linux #760

+From: Aron Szabo <aron@aron.ws>
+Date: Sat, 16 Jun 2012 12:15:55 +0200
+Subject: [PATCH 016/121] lirc: added support for RaspberryPi GPIO
+
+lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others
+See: https://github.com/raspberrypi/linux/issues/525
+
+lirc: Remove restriction on gpio pins that can be used with lirc
+
+Compute Module, for example could use different pins
+
+lirc_rpi: Add parameter to specify input pin pull
+
+Depending on the connected IR circuitry it might be desirable to change the
+gpios internal pull from it pull-down default behaviour. Add a module
+parameter to allow the user to set it explicitly.
+
+Signed-off-by: Julian Scheel <julian@jusst.de>
+
+lirc-rpi: Use the higher-level irq control functions
+
+This module used to access the irq_chip methods of the
+gpio controller directly, rather than going through the
+standard enable_irq/irq_set_irq_type functions. This
+caused problems on pinctrl-bcm2835 which only implements
+the irq_enable/disable methods and not irq_unmask/mask.
+
+lirc-rpi: Correct the interrupt usage
+
+1) Correct the use of enable_irq (i.e. don't call it so often)
+2) Correct the shutdown sequence.
+3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier
+
+lirc-rpi: use getnstimeofday instead of read_current_timer
+
+read_current_timer isn't guaranteed to return values in
+microseconds, and indeed it doesn't on a Pi2.
+
+Issue: linux#827
+
+lirc-rpi: Add device tree support, and a suitable overlay
+
+The overlay supports DT parameters that match the old module
+parameters, except that gpio_in_pull should be set using the
+strings "up", "down" or "off".
+
+lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode

+As part of migrating to use the Common Clock Framework, replace clk_enable()
+with clk_prepare_enable() and clk_disable() with clk_disable_unprepare().
+This does not affect behaviour under the current clock implementation.
+
+Also add a missing clk_disable_unprepare() in the probe error path.

+Subject: [PATCH 020/121] Add Chris Boot's i2c driver
+
+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

+From 5b2523aae9c5beb443315a7814633fc740992d07 Mon Sep 17 00:00:00 2001
+From: Phil Elwell <phil@raspberrypi.org>
+Date: Mon, 11 May 2015 09:00:42 +0100
+Subject: [PATCH 023/121] 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.

+Subject: [PATCH 029/121] 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.

+Subject: [PATCH 031/121] enabling the realtime clock 1-wire chip DS1307 and
+ 1-wire on GPIO4 (as a module)
+
+1-wire: Add support for configuring pin for w1-gpio kernel module
+See: https://github.com/raspberrypi/linux/pull/457
+
+Add bitbanging pullups, use them for w1-gpio
+
+Allows parasite power to work, uses module option pullup=1
+
+bcm2708: Ensure 1-wire pullup is disabled by default, and expose as module parameter
+
+Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
+
+w1-gpio: Add gpiopin module parameter and correctly free up gpio pull-up pin, if set
+
+Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
+
+w1-gpio: Sort out the pullup/parasitic power tangle

+Subject: [PATCH 040/121] ASoC: wm8804: Implement MCLK configuration options,
+ add 32bit support WM8804 can run with PLL frequencies of 256xfs and 128xfs
+ for most sample rates. At 192kHz only 128xfs is supported. The existing
+ driver selects 128xfs automatically for some lower samples rates. By using an
+ additional mclk_div divider, it is now possible to control the behaviour.
+ This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It
+ should allow lower jitter and better signal quality. The behavior has to be
+ controlled by the sound card driver, because some sample frequency share the
+ same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only
+ difference is the MCLK divider.
+
+This also added support for 32bit data.

+
+Signed-off-by: Daniel Matuschek <daniel@matuschek.net>
+
+Add a parameter to turn off SPDIF output if no audio is playing
+
+This patch adds the paramater auto_shutdown_output to the kernel module.
+Default behaviour of the module is the same, but when auto_shutdown_output
+is set to 1, the SPDIF oputput will shutdown if no stream is playing.
+
+bugfix for 32kHz sample rate, was missing
+
+HiFiBerry Digi: set SPDIF status bits for sample rate
+
+The HiFiBerry Digi driver did not signal the sample rate in the SPDIF status bits.
+While this is optional, some DACs and receivers do not accept this signal. This patch
+adds the sample rate bits in the SPDIF status block.

+
+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.

+Subject: [PATCH 048/121] 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.

+Subject: [PATCH 049/121] bcm2708: Allow option card devices to be configured
+ via DT
+
+If the kernel is built with Device Tree support, and if a DT blob
+is provided for the kernel at boot time, then the platform devices
+for option cards are not created. This avoids both the need to
+blacklist unwanted devices, and the need to update the board
+support code with each new device.

+Subject: [PATCH 058/121] pinctrl-bcm2835: Fix interrupt handling for GPIOs
+ 28-31 and 46-53
+
+Contrary to the documentation, the BCM2835 GPIO controller actually has
+four interrupt lines - one each for the three IRQ groups and one common. Rather
+confusingly, the GPIO interrupt groups don't correspond directly with the GPIO
+control banks. Instead, GPIOs 0-27 generate IRQ GPIO0, 28-45 GPIO1 and
+46-53 GPIO2.
+
+Awkwardly, the GPIOS for IRQ GPIO1 straddle two 32-entry GPIO banks, so it is
+cleaner to split out a function to process the interrupts for a single GPIO
+bank.
+
+This bug has only just been observed because GPIOs above 27 can only be
+accessed on an old Raspberry Pi with the optional P5 header fitted, where
+the pins are often used for I2S instead.

+Subject: [PATCH 059/121] pinctrl-bcm2835: Only request the interrupts listed
+ in the DTB
+
+Although the GPIO controller can generate three interrupts (four counting
+the common one), the device tree files currently only specify two. In the
+absence of the third, simply don't register that interrupt (as opposed to
+registering 0), which has the effect of making it impossible to generate
+interrupts for GPIOs 46-53 which, since they share pins with the SD card
+interface, is unlikely to be a problem.

+Subject: [PATCH 087/121] 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 090/121] 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.

+Subject: [PATCH 099/121] 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.
