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 vsp1 driver implements very partial colour space support: it
hardcodes the colorspace field on all video devices and subdevices to
V4L2_COLORSPACE_SRGB, regardless of the configured format. The
xfer_func, ycbcr_enc and quantization fields are not set (except for
hsv_enc for HSV formats on video devices). This doesn't match the
hardware configuration, which handles YUV data as encoding in BT.601
with limited range.
As a first step towards colour space configuration, keep the colour
space fields hardcoded, but set them based on the selected format type
(RGB, YUV or HSV).
While at it, remove an extra blank line.

The vsp1_dl library allows to program a display list and feed it
continuously to the VSP2. As an alternative operation mode, the library
allows to program the VSP2 in 'single shot' mode, where a display list
is submitted to the VSP on request only.
Currently the 'single shot' mode is only available when the VSP2 is
controlled by userspace, while it works in continuous mode when driven
by DRM, as frames have to be submitted to the display continuously.
For the VSPX use case, where there is no uapi support, we should however
work in single-shot mode as the ISP driver programs the VSPX on
request.
Initialize the display lists in single shot mode in case the VSP1 is
controlled by userspace or in case the pipeline features an IIF entity,
as in the VSPX case.

Some R-Car ISP instances have in addition to the channel selector (CS)
an ISP core (CORE) to perform operations on an image stream. The core
function is mapped to a different memory region and has a separate
interrupt than CS, extend the bindings to allow describing this.
On the same SoC different instances of the ISP IP may have, or not have,
the CORE functionality. The CS function on all instances on the SoC are
the same and the documentation describes the full ISP (CS + CORE) as a
single IP block. Where instances not having the CORE function simply
lack the functionality to modify the image data. There are dependencies
on the CS functionality while operating the CORE functionality.
In order for the ISP core to function in memory-to-memory mode it needs
to be feed input data from a Streaming Bridge interface. This interface
is provided thru the VSP-X device. Add an optional new property
"renesas,vspx" to provide a phandle to describe this relationship.
While adding mandatory reg-names and interrupt-names breaks existing
bindings the driver itself remains backward compatible and provides CS
functionality if a single unnamed reg and interrupt property is present.
Furthermore all existing users of the bindings are updated in following
work to add these new mandatory properties.

platform. It belongs to same iris v3 family as that of SM8550 but is a
downscaled version of SM8550. It has 2 frame processing hardware blocks
while SM8550 has 4. Thereby QCS8300 have fewer capabilities than those
of SM8550.

Add support for the SM8650 platform by re-using the SM8550
definitions and using the vpu33 ops.
Move the Sm8650 reset tables that differs in a per-SoC platform
header, that will contain mode SoC specific data when
more codecs are introduced.
The SM8650/vpu33 requires more reset lines, but the H.264
decoder capabilities are identical.

Since commit 88785982a1 ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.
Set the queue lock to &video->queue_lock, which makes it possible to drop
the wait_prepare/finish callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.
Note that the lock field of struct video_device is never set in this
driver, so the core v4l2_ioctl.c function v4l2_ioctl_get_lock() will never
take a lock.
