Avoid duplication of enumerated pixelformat on the bytecap
video capture device. Indeed, since the bytecap format list
contains both CSI & parallel 16bits formats, ensure that same
pixelformat are not reported twice when performing enumeration
of supported formats.

In preparation of the introduction of dcmipp csi input support, rename
the dcmipp_parallel subdev into a generic dcmipp_input which will be in
charge of handling both parallel input & csi input.
Only structures / variables / functions and file naming are changed without

There apparently is no reason to require 3 queued buffers to call
streamon() for the RkISP1 as the driver operates with a scratch buffer
where frames can be directed to if there's no available buffer provided
by userspace.
Reduce the number of required buffers to 1 to allow applications to
operate with a single queued buffer.
Tested with libcamera, by operating with a single capture request. The
same request (and associated capture buffer) gets recycled once
completed. This of course causes a frame rate drop but doesn't hinder
operations.

This commit fixes an unused value issue detected by Coverity (CID
1519008). The error condition for the invalid MIPI CSI-2 is not properly
handled as the break statement would only exit the switch block and not
the entire loop. Fix this by breaking from the look immediately after
the switch block when an error occurs.

The proble is on the first line:
if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i]))
If jpeg->pd_dev[i] is an error pointer, then passing it to
pm_runtime_suspended() will lead to an Oops. The other conditions
check for both error pointers and NULL, but it would be more clear to
use the IS_ERR_OR_NULL() check for that.

The platform compatibility checks for MT8183 and
MT8195 in mdp_cmdq_prepare() are redundant as they are
done in __get_config_offset() itself. Furthermore
there are two if-else branch in __get_config_offset()
which have similar conditions and are redundant.
To address this, remove the check in mdp_cmdq_prepare()
and combine the two if-else branch into one in
__get_config_offset().

Rearrange inst destruction. First remove the inst from the
core->instances list, second synchronize IRQ/IRQ-thread to
make sure that nothing else would see the inst while we take
it down.

We destroy mutex-es too early as they are still taken in
v4l2_fh_exit()->v4l2_event_unsubscribe()->v4l2_ctrl_find().
We should destroy mutex-es right before kfree(). Also
do not vdec_ctrl_deinit() before v4l2_fh_exit().

When using buffers from DRM, DMA-API gives a warning about: "mapping sg
segment longer than device claims to support [len=307200] [max=65536]"
Add a call to vb2_dma_contig_set_max_seg_size() to tell the DMA-API
about the supported segment size (which is UINT_MAX).

Since commit 88785982a19d ("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.
Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.

Add a 'yuv' flag to the `rzg2l_cru_ip_format` structure to indicate
whether a given format is YUV-based and update the `rzg2l_cru_ip_formats`
array with this flag appropriately. This change enables a more efficient
way to check if the input and output formats use the same colorspace.
With this change, we can eliminate the use of `v4l2_format_info()` in
`rzg2l_cru_initialize_image_conv()` as the necessary details for the source
and destination formats are already available through the `yuv` flag.

Implement the `.link_validate()` callback for the video node and move the
format checking into this function. This change allows the removal of
`rzg2l_cru_mc_validate_format()`.
Note, the fmt.format.code and fmt.format.field checks have be dropped as
the subdev .set_fmt() handler ensures that those fields always hold valid
values.
