GPIO IR receive is much rely on interrupt response, uneven interrupt
latency will lead to incorrect timing, so the decoder fails to decode
it. The issue is particularly acute on some systems which support
cpuidle, not all, dynamically disable and enable cpuidle can solve this
problem to a great extent.
However, there is a downside to this approach, the measurement of header
on the first frame may incorrect. Test on i.MX8M serials, when enable
cpuidle, interrupt latency could be about 500us.
With this patch:
1. has no side effect on non-cpuidle system, even runtime pm api won't
be invoked to avoid a bunch of pm busy work for devices that do not need
it, including spinlocks, ktime, etc.
2. latency is still much longer for the first gpio interrupt on cpuidle
system, so the first frame may not be decoded. Generally, RC would transmit
multiple frames at once press, we can sacrifice the first frame.
3. add "linux,autosuspend-period" property in device tree if you also
suffer this cpuidle issue.

Constify a number of static structs that were not modified. In order to
be able to do that, const input arguments to a couple of functions that
not modify their argument. This allows the compiler to put them in
read-only memory, resulting in about 6k memory being read-only, and the
resulting module is 400 bytes smaller.

The .suspend() and .resume() callbacks are not defined for this driver.
Thus, just the unlisting of PM pointers in the struct initializer will make
no change in its behavior. Still unlisting is necessary so as to get rid of
.suspend and .resume pointers as they are part of the legacy framework and
should not be used in the driver code explicitly.

If you do sanity checks, you should do them for both endpoints.

As per spec, the CAPTURE resolution should be automatically set based on
the OUTPUT resolution. This patch properly propagate width/height to the
capture when the OUTPUT format is set and override the user provided
width/height with configured OUTPUT resolution when the CAPTURE fmt is
updated.
This also prevents userspace from selecting a CAPTURE resolution that is
too small, avoiding kernel oops.

This patch changes the device configuration to support capture
of V4L2_PIX_FMT_GREY video. The 'write_format' field of the format
description should be planar.
Also the array 'pixm->plane_fmt' that describes the planes should
be memset to 0 before filling it since the the cb, cr planes should

src pad
Add support to more YUV encoded media bus formats on the resizer's
source pad. The patch defines an array rkisp1_rsz_yuv_formats[]
with the list of supported YUV media bus formats and their {hv}div
values. The {hv}div are used in the function 'rkisp1_rsz_config'
instead of the macros RKISP1_MBUS_FMT_(HV)DIV, and instead of
checking the capture format.

to the capture
Currently the resizer outputs the same media bus format
as the input. This is wrong since the resizer is also used
to downscale YUV formats. This patch changes the enumeration
of the supported formats. The supported formats on the sink pad
should be taken from the isp entity and the supported formats on
the source pad should be taken from the capture entity.

formats on capture
Add a function 'rkisp1_cap_enum_mbus_codes' that receive
a pointer to 'v4l2_subdev_mbus_code_enum' and returns the
next supported mbus format of the capture. The function
assumes that pixel formats with identical 'mbus' are grouped
together in the hardcoded arrays, therefore the order of the
entries in the array 'rkisp1_sp_fmts' are adjusted.
This function is a helper for the media bus enumeration of
the source pad of the resizer entity.

'rkisp1_capture_fmt_cfg' which maps the video format

According to the TRM [1], the YUV->RGB conversion outputs
RGB 888 format with 4 bytes, where the last byte is ignored,
using big endian representation:
|___X___|___R___|___G___|___B___|
31 24 16 8 0
Which matches format V4L2_PIX_FMT_XBGR32 in little endian
representation, so replace it accordingly.
"24 bit word". What it means is that 4 bytes are used with
24bit for the RGB and the last byte is ignored.
This matches format V4L2_PIX_FMT_XBGR32.

The Documentation/DMA-API-HOWTO.txt states that dma_map_sg returns the
numer of the created entries in the DMA address space. However the
subsequent calls to dma_sync_sg_for_{device,cpu} and dma_unmap_sg must be
called with the original number of entries passed to dma_map_sg. The
sg_table->nents in turn holds the result of the dma_map_sg call as stated
in include/linux/scatterlist.h. Adapt the code to obey those rules.
While touching this code, update it to use the modern DMA_FROM_DEVICE
definitions.

The suspend/resume functions have no callers depending on
configuration, so they must be marked __maybe_unused to
avoid these harmless warnings:
drivers/media/platform/marvell-ccic/mmp-driver.c:347:12: warning:
'mmpcam_resume' defined but not used [-Wunused-function]
347 | static int mmpcam_resume(struct device *dev)
| ^~~~~~~~~~~~~
drivers/media/platform/marvell-ccic/mmp-driver.c:338:12: warning:
'mmpcam_suspend' defined but not used [-Wunused-function]
338 | static int mmpcam_suspend(struct device *dev)
| ^~~~~~~~~~~~~~

tc358743_cec_isr is misnammed, it is not the main isr.
So rename it to be consistent with its siblings,
tc358743_cec_handler.
It also does not check if its input parameter 'handled' is
is non NULL like its siblings, so add a check.
