During initialization, the post processor allocates the same number of
buffers as the buf queue.
As the init function is called in streamon(), if an allocation fails,
streamon will return an error and streamoff() will not be called, keeping
all post processor buffers allocated.
To avoid that, all post proc buffers are freed in case of an allocation
error.

The vsp1 driver implements very partial colour space support: it

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).

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.

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.

The IRIS acceleration found in the SM8650 platforms uses the vpu33
hardware version, and requires a slighly different reset and power off
sequences in order to properly get out of runtime suspend.

The vpu33 HW is very close to vpu3, and shares most of the
operations, so rename file to vpu3x since we'll handle all vpu3

Introduce an optional controller_rst_tbl use to store reset lines
used to reset part of the controller.
This is necessary for the vpu3 support, when the xo reset line
must be asserted separately from the other reset line
on power off operation.
Factor the iris_init_resets() logic to allow requesting
multiple reset tables.

Currently, if streamon/streamoff calls are imbalanced we can either end up
with a negative ISI m2m usage_count (if streamoff() is called more times
than streamon()) in which case we'll not be able to restart the ISI pipe
next time, or the usage_count never gets to 0 and the pipe is never
switched off.
To avoid that, add a 'streaming' flag to mxc_isi_m2m_ctx_queue_data and use it
in the streamon/streamoff to avoid incrementing/decrementing the usage_count
uselessly, if called multiple times from the same context.

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.

In fimc_is_hw_change_mode(), the function changes camera modes without
waiting for hardware completion, risking corrupted data or system hangs
if subsequent operations proceed before the hardware is ready.
Add fimc_is_hw_wait_intmsr0_intmsd0() after mode configuration, ensuring
hardware state synchronization and stable interrupt handling.
