From 48342ae751c797ac73ac9c894b3f312df18ffd21 Mon Sep 17 00:00:00 2001
From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: Wed, 15 Sep 2021 13:46:20 +0100
Subject: [PATCH] ARM: 9124/1: uncompress: Parse "linux,usable-memory-range" DT
property
Add support for parsing the "linux,usable-memory-range" DT property.
This property is used to describe the usable memory reserved for the
crash dump kernel, and thus makes the memory reservation explicit.
If present, Linux no longer needs to mask the program counter, and rely
on the "mem=" kernel parameter to obtain the start and size of usable
memory.
For backwards compatibility, the traditional method to derive the start
of memory is still used if "linux,usable-memory-range" is absent.

From b3b76fc86f0fb4d98918f48c784138bfa950dff6 Mon Sep 17 00:00:00 2001
From: Felix Fietkau <nbd@nbd.name>
Date: Wed, 15 Jun 2022 14:53:34 +0200
Subject: [PATCH] PCI: mediatek: Allow building for ARCH_AIROHA
Allow selecting the pcie-mediatek driver if ARCH_AIROHA is set, because the
Airoha EN7523 SoC uses the same controller as MT7622.
The driver itself is not modified. The PCIe controller DT node should use
mediatek,mt7622-pcie after airoha,en7523-pcie.

Subject: [PATCH] Revert "mailbox: avoid timer start from callback"
This reverts commit c7dacf5b0f32957b24ef29df1207dc2cd8307743.
The Pi 400 shutdown/poweroff mechanism relies on being able to set
a GPIO on the expander in the pm_power_off handler, something that
requires two mailbox calls - GET_GPIO_STATE and SET_GPIO_STATE. A
recent kernel change introduces a reasonable possibility that the
GET call doesn't completes, and bisecting led to a commit from
October that changes the timer usage of the mailbox.
My theory is that there is a race condition in the new code that breaks
the poll timer, but that it normally goes unnoticed because subsequent
mailbox activity wakes it up again. The power-off mailbox calls happen
at a time when other subsystems have been shut down, so if one of them
fails then there is nothing to allow it to recover.

Load driver early since at least bcm2708_fb doesn't support deferred

Support the legacy DMA API which is needed by bcm2708_fb.
Don't mask out channel 2.

Subject: [PATCH] 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.

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.

At present there is no mechanism to specify driver load order,
which can lead to deferrals and repeated retries until successful.
Since this situation is expected, reduce the dmesg level to
INFO and mention that the operation will be retried.

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] 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 driver looks for DT aliases of the form "serial<n>",
and if found uses <n> as the device ID. This can cause
/dev/ttyAMA0 to become /dev/ttyAMA1, which is confusing if the
other serial port is provided by the 8250 driver which doesn't
use the same logic.

Subject: [PATCH] amba_pl011: Round input clock up
The UART clock is initialised to be as close to the requested
frequency as possible without exceeding it. Now that there is a
clock manager that returns the actual frequencies, an expected
48MHz clock is reported as 47999625. If the requested baudrate
== requested clock/16, there is no headroom and the slight
reduction in actual clock rate results in failure.
Detect cases where it looks like a "round" clock was chosen and
adjust the reported clock to match that "round" value. As the
code comment says:
/*
* If increasing a clock by less than 0.1% changes it
* from ..999.. to ..000.., round up.

Subject: [PATCH] amba_pl011: Insert mb() for correct FIFO handling
The pl011 register accessor functions use the _relaxed versions of the
standard readl() and writel() functions, meaning that there are no
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: Make TX optimisation conditional
pl011_tx_chars takes a "from_irq" parameter to reduce the number of
register accesses. When from_irq is true the function assumes that the
FIFO is half empty and writes up to half a FIFO's worth of bytes
without polling the FIFO status register, the reasoning being that
the function is being called as a result of the TX interrupt being
raised. This logic would work were it not for the fact that
pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases
the spinlock before calling tty_flip_buffer_push.
A user thread writing to the UART claims the spinlock and ultimately
calls pl011_tx_chars with from_irq set to false. This reverts to the
older logic that polls the FIFO status register before sending every
byte. If this happen on an SMP system during the section of the IRQ
handler where the spinlock has been released, then by the time the TX
interrupt handler is called, the FIFO may already be full, and any
further writes are likely to be lost.
The fix involves adding a per-port flag that is true iff running from
within the interrupt handler and the spinlock has not yet been released.
This flag is then used as the value for the from_irq parameter of
pl011_tx_chars, causing polling to be used in the unsafe case.

Subject: [PATCH] tty: amba-pl011: Add un/throttle support
The PL011 driver lacks throttle and unthrottle methods. As a result,
sending more data to the Pi than it can immediately sink while CRTSCTS
is enabled causes a NULL pointer to be followed.
Add a throttle handler that disables the RX interrupts, and an
unthrottle handler that reenables them.

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.

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.

From cac14f80f1e41f9a977c3cd84b0b3b73740818f8 Mon Sep 17 00:00:00 2001
From: Harm Hanemaaijer <fgenfb@yahoo.com>
Date: Thu, 20 Jun 2013 20:21:39 +0200
Subject: [PATCH] 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] 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.
Signed-off-by: Florian Meier <florian.meier@koalo.de>
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: do device registration in the board file
Don't register the device in the driver. Do it in the board file.

dmaengine: bcm2708: don't restrict DT support to ARCH_BCM2835
Both ARCH_BCM2835 and ARCH_BCM270x are built with OF now.
Add Device Tree support to the non ARCH_BCM2835 case.
Use the same driver name regardless of architecture.
Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
BCM270x_DT: add bcm2835-dma entry
Add Device Tree entry for bcm2835-dma.
The entry doesn't contain any resources since they are handled
by the arch/arm/mach-bcm270x/dma.c driver.
In non-DT mode, don't add the device in the board file.
Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
bcm2708-dmaengine: Add debug options
BCM270x: Add memory and irq resources to dmaengine device and DT
Prepare for merging of the legacy DMA API arch driver dma.c
with bcm2708-dmaengine by adding memory and irq resources both
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
Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
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
https://github.com/raspberrypi/linux/issues/1108
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.
Fixes https://github.com/raspberrypi/linux/issues/2056

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.

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.
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] 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.

Subject: [PATCH] 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] 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.
