It is required by the standard that the field order is set by the
driver, default to NONE in case any is provided, but we can basically
accept any value provided by the userspace as we will anyway not
be able to do any deinterlacing.
In this patch we also make sure to pass the interlacing mode provided
by userspace from the output to the capture side of the device so
that the information is given back to userspace. This way it can
handle it and potentially deinterlace afterward.

Fixes for colorspace logic in exynos-gsc and s5p-mfc drivers
Hello,
This patchset fixes a few issues on the colorspace logic for the exynos-gsc
and s5p-mfc drivers.
We now handle the colorspace in those drivers, and make sure to respect user setting if
possible.
We also now set the 'v4l2_pix_format:field' if userspace passed ANY, and
replicate users value on the capture side.
This is the sixth version of the patch serie.
Best regards,
Thibault Saunier

- Fix a silly build error that slipped in while rebasing the patches
Series-changes: 3
- Do not check values in the g_fmt functions as Andrzej explained in previous review
Series-changes: 5
- Just adapt the field and never error out.
Series-changes: 6
- Pass user output field value to the capture as the device is not
doing any deinterlacing and thus decoded content will still be
interlaced on the output.
Use colorspace provided by the user as we are only doing scaling and
color encoding conversion, we won't be able to transform the colorspace
itself and the colorspace won't mater in that operation.
Also always use output colorspace on the capture side.
If the user does not provide a colorspace do no make it up, we might
later while processing need to figure out the colorspace, which
is possible depending on the frame size but do not ever guess and
leak that guess to the userspace.

This patch enables support for such pre-allocated block based allocator
always for MFC v6+ devices. Due to the limitations of the memory management
subsystem the largest supported size of the pre-allocated buffer when no
CMA (Contiguous Memory Allocator) is enabled is 4MiB.
This patch also removes the requirement to provide two reserved memory
regions for MFC v6+ devices in device tree. Now the driver is fully
functional without them.

Such relaxed requirements for the memory buffers can be easily fulfilled
by allocating firmware, device and per-context buffers from the probe-time
preallocated larger buffer. This patch adds support for it. This way the
driver finally works fine on ARM64 architecture. The size of the
preallocated buffer is 8 MiB, what is enough for three instances H264
decoders or encoders (other codecs have smaller memory requirements).
If one needs more for particular use case, one can use "mem" module
parameter to force larger (or smaller) buffer (for example by adding
"s5p_mfc.mem=16M" to kernel command line).

Initialize members of the internal device and context structures as early
as possible to avoid access to uninitialized objects on initialization
failures. If loading firmware or creating of the hardware instance fails,
driver will access device or context queue in error handling path, which
might not be initialized yet, what causes kernel panic. Fix this by moving
initialization of all static members as early as possible.
