The ret variable can be returned uninitialized in the
imx_media_create_pad_vdev_lists() function is imxmd->num_vdevs is zero.
Fix it.

I ran into a rare build error during randconfig testing:
drivers/staging/media/imx/imx-media-capture.o: In function `capture_stop_streaming':
imx-media-capture.c:(.text+0x224): undefined reference to `vb2_buffer_done'
drivers/staging/media/imx/imx-media-capture.o: In function `imx_media_capture_device_register':
imx-media-capture.c:(.text+0xe60): undefined reference to `vb2_queue_init'
imx-media-capture.c:(.text+0xfa0): undefined reference to `vb2_dma_contig_memops'
While VIDEOBUF2_DMA_CONTIG was already selected by the camera driver,
it wasn't necessarily there with just the base driver enabled.
This moves the 'select' statement to the top-level option to make
sure it's always available.

These vb2_ops structures are only stored in the ops field of a
vb2_queue structure, which is declared as const. Thus the vb2_ops
structures themselves can be const.

While looking at a compiler warning, I noticed the use of
IS_ERR_OR_NULL, which is generally a sign of a bad API design
and should be avoided.
In this driver, this is fairly easy, we can simply stop storing
error pointers in persistent structures, and change the two
functions that might return either a NULL pointer or an error
code to consistently return error pointers when failing.
of_parse_subdev() now separates the error code and the pointer
it looks up, to clarify the interface. There are two cases
where this function originally returns 'NULL', and I have
changed that to '0' for success to keep the current behavior,
though returning an error would also make sense there.

For the write channels with 4:2:0 subsampled YUV formats, avoid chroma
overdraw by only writing chroma for even lines. Reduces necessary write
memory bandwidth by at least 25% (more with rotation enabled).

Calling S_STREAM OFF multiple times on a video device is valid, although
dubious, practice. Instead of warning about it and setting stream count
lower than zero, just ignore the subsequent S_STREAM calls and correct
the stream count to zero.

This patch adds a call to imx_media_fill_default_mbus_fields() in the
*_try_fmt() functions at the sink pads, to set empty field order and
colorimetry parameters.
If the field order is set to ANY, choose the currently set field order
at the sink pad. If the colorspace is set to DEFAULT, choose the
current colorspace at the sink pad. If any of xfer_func, ycbcr_enc
or quantization are set to DEFAULT, either choose the current sink pad
setting, or the default setting for the new colorspace, if non-DEFAULT
colorspace was given.
If a format is destined to be routed through the Image Converter,
fixed quantization and Y`CbCr encoding must be set.
Colorimetry is also propagated from sink to source pads anywhere
this has not already been done.

Add frame size and frame interval enumeration to CSI.
CSI can downscale the image independently horizontally and vertically by a
factor of two, which enumerates to four different frame sizes at the
output pads. The input pad supports a range of frame sizes.
CSI can also drop frames, resulting in frame rate reduction, so
enumerate the resulting possible output frame rates.

Adds MIPI CSI-2 Receiver subdev driver. This subdev is required
for sensors with a MIPI CSI2 interface.
- Switch from the v4l2_of_ APIs to the v4l2_fwnode_ APIs.
- Add the function csi2ipu_gasket_init() to initialize the gasket at
s_power(ON). The gasket needs to be programmed with the correct color
component ordering to handle UYVY vs. YUYV ordered mbus formats from
sensors. Note that the description of the CSI2IPU_GASKET register in
the i.MX6 reference manual is wrong w.r.t bit 2 (the manual refers to
this register as CSI2_SW_RST): setting bit 2 selects YUYV order, not UYVY.

This is a set of three media entity subdevice drivers for the i.MX
Image Converter:
- Pre-process Router: Takes input frames from CSI0, CSI1, or VDIC.
Two output pads enable either or both of the preprocess tasks
below. If the input is from one of the CSIs, both proprocess task
links can be enabled to process frames from that CSI simultaneously.
If the input is the VDIC, only the Pre-processing Viewfinder task
link can be enabled.
- Pre-processing Encode task: video frames are routed directly from
the CSI and can be scaled, color-space converted, and rotated.
Scaled output is limited to 1024x1024 resolution. Output frames
are routed to the prpenc capture device.
- Pre-processing Viewfinder task: this task can perform the same
conversions as the pre-process encode task, but in addition can
be used for hardware motion compensated deinterlacing. Frames can
come either directly from the CSI or from the VDIC. Scaled output
is limited to 1024x1024 resolution. Output frames are routed to
the prpvf capture device.

This is the capture device interface driver that provides the v4l2

- directly from CSI for capturing unconverted images directly from
camera sensors.
- from the IC pre-process encode task.
- from the IC pre-process viewfinder task.
