The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Pull ARM SoC driver updates from Arnd Bergmann:
"The main change this time was the introduction of the drivers/genpd
subsystem that gets split out from drivers/soc to keep common
functionality together.
The SCMI driver subsystem gets an update to version 3.2 of the

firmware drivers.
On the soc driver side, the updates are mostly cleanups across a
number of Arm platforms. On driver for loongarch adds power management
for DT based systems, another driver is for HiSilicon's Arm server
chips with their HCCS system health interface.
The remaining updates for the most part add support for additional
hardware in existing drivers or contain minor cleanups. Most of these

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Record SCU wakeup interrupt in /sys/power/pm_wakeup_irq
The user can further identify the exact wakeup source by using the
following interface:
cat /sys/firmware/scu_wakeup_source/wakeup_src
The above will print the wake groups and the irqs that could have
contributed to waking up the kernel. For example if ON/OFF button was the
wakeup source:
cat /sys/firmware/scu_wakeup_source/wakeup_src
Wakeup source group = 3, irq = 0x1
The user can refer to the SCFW API documentation to identify all the

In order to save power, we only need to request a channel
when the communication with the DSP active.
For this we export the following functions:
- imx_dsp_request_channel, gets a channel with a given index
- imx_dsp_free_channel, frees a channel with a given index
Notice that we still request channels at probe to support devices
that do not have PM callbacks implemented.
More explanations about why requesting a channel has an effect
on power savings:
- requesting an mailbox channel will call mailbox's startup
function.
- startup function calls pm_runtime_get_sync which increments device
usage count and will keep the device active. Specifically, mailbox
clock will be always ON when a mailbox channel is requested.

The header of the message to send can be changed if the
response is longer than the request:
- 1st word, the header is sent
- the remaining words of the message are sent
- the response is received asynchronously during the
execution of the loop, changing the size field in
the header
- the for loop test the termination condition using
the corrupted header
It is the case for the API build_info which has just a
header as request but 3 words in response.

The imx SC api strongly assumes that messages are composed out of

This produces many oopses with CONFIG_KASAN=y.
Fix by marking with __aligned(4).
