Add support and enable decoding of H264 High 10 and 4:2:2 profiles.
Decoded CAPTURE buffer width is aligned to 64 pixels to accommodate HW

The "media: atomisp: Add support for sensors with a separate ISP
v4l2_subdev" combined with some pending drivers/media/i2c/mt9m114.c changes
makes the atomisp work nicely with the standard V4L2 mt9m114.c driver,
avoiding the need for the atomisp specific atomisp-mt9m114 driver.
The normal driver actually works better since the atomisp-mt9m114 driver
does not have working exposure control, leading to a much too dark image.
Remove the no longer necessary atomisp-mt9m114 driver.

Some sensors have an ISP inside the sensor which the sensor driver models
as a separate v4l2-subdev, like the mt9m114 sensor-driver does.
Since the atomisp driver emulates a standard /dev/video# v4l2-device
without requiring the application to be aware of media-controller centric
/dev/video# devices this requires some special handling in the driver.
Add support for this setup to the atomisp driver.

When a (sensor) v4l2_subdev has its state_lock member set to non NULL,
then all v4l2_subdev_state-s for the sensor share the same lock.
atomisp_init_sensor() calls v4l2_subdev_lock_and_get_active_state() and
then later on also tries to lock a separate v4l2_subdev_state used for try
calls (rather then changing the active state), while still holding
the active state lock.
Since this try v4l2_subdev_state shares a lock with the active state this
results in a deadlock.
Skip locking try_sd_state when sensor->state_lock is set to avoid this.

atomisp_try_fmt() is limiting the width of the requested resolution to 1920
before calling the sensor's try_fmt() method. But it is not limiting
the height. In case of the old mode-list based t4ka3 driver which has
a mode list of:
736x496
896x736
1936x1096
3280x2464
This results in 3280x2464 being selected when try_fmt is called
with a requested resolution of 3280x2464, which is not supported because
its width > 1920 .
Fix this by also limiting the height when in preview mode.

The GMIN code has support for sensors using external regulators enabled
by GPIOS, rather then using regulators build into the PMIC.
With the exception of the Trekstor ST70408-4 (1) tablet there are no known
devices which actually use external regulators for the sensors and the code
for this is using deprecated old style GPIO numbers support for which is
going away.
Remove the GPIO driven regulator support so that the gmin code no longer
depends on deprecated GPIO APIs.
1) The GMIN support itself is also deprecated and all sensor drivers still
using it are being moved over to use ACPI + runtime-pm and the ST70408-4
shipped with Android as factory OS and thus will have broken ACPI tables
for the sensors, so like other Android factory OS tablets it will need
a bespoke solution anyways.

The axis-fifo driver performs a full hardware reset (via
reset_ip_core()) in several error paths within the read and write
functions. This reset flushes both TX and RX FIFOs and resets the
AXI-Stream links.

or data loss in other FIFO paths.

Remove erroneous subtraction of 4 from the total FIFO depth read from
device tree. The stored depth is for checking against total capacity,
not initial vacancy. This prevented writes near the FIFO's full size.
The check performed just before data transfer, which uses live reads of
the TDFV register to determine current vacancy, correctly handles the
initial Depth - 4 hardware state and subsequent FIFO fullness.

The mode setting logic in ad7816_store_mode was reversed due to
incorrect handling of the strcmp return value. strcmp returns 0 on
match, so the `if (strcmp(buf, "full"))` block executed when the
input was not "full".
This resulted in "full" setting the mode to AD7816_PD (power-down) and
other inputs setting it to AD7816_FULL.
Fix this by checking it against 0 to correctly check for "full" and
"power-down", mapping them to AD7816_FULL and AD7816_PD respectively.

The VIDIOC_ENUM_FRAMESIZES ioctl should return all frame sizes (i.e.

format.
It doesn't make a lot of sense to return the frame-sizes in a stepwise
manner, which is used to enforce hardware alignments requirements for
CAPTURE buffers, for coded formats.
Instead, applications should receive an indication, about the maximum
supported frame size for that hardware decoder, via a continuous

Pull staging driver updates from Greg KH:
"Here is the big set of staging driver cleanups and updates for
6.15-rc1.
As expected, with the introduction of the gpib drivers, loads of
cleanups and fixes showed up, with the huge majority of changes being
for that chunk of drivers. This is good and shows that the community
can fix up things in public when asked to. Also included in here are:
- small sm750fb cleanups
- tiny rtl8723bs cleanups
- more vchiq_arm cleanups and changes, hopefully this will get out of
staging soon
All of these have been in linux-next for almost 2 weeks now with no
reported issues"

Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

Creating the keep-alive thread in vchiq_platform_init_state have
the following advantages:
- abort driver probe if kthread_create fails (more consistent behavior)
- make resource release process easier
Since vchiq_keepalive_thread_func is defined below
vchiq_platform_init_state, the latter must be moved.

The commit 2a4d15a4ae98 ("staging: vchiq: Refactor vchiq cdev code")
moved the debugfs directory creation before vchiq character device
registration. In case the latter fails, the debugfs directory won't
be cleaned up.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.
