Add the decoder and encoder implementing the v4l2
API. This patch also adds the Makefile and the VIDEO_WAVE_VPU config

Regarding the EOPNOTSUPP discussion: I discussed this some more with
Nicolas on irc, and we wonder if it isn't better to just drop create_bufs
support for the wave5 decoder altogether. Is there any point in supporting
it for OUTPUT but not CAPTURE?

So this would just be dropped.

This also means there is no need to document the new EOPNOTSUPP error
code in VIDIOC_CREATE_BUFS, or to modify v4l2-compliance.

You *do* need to add a comment somewhere explaining why you don't
support this ioctl. I think it would be best to do that right after
'.vidioc_reqbufs = v4l2_m2m_ioctl_reqbufs,'.

So, besides this issue would you judge the v4l2 layer of the driver to
be ready? Do you want a reviewed by tag for it or would you take it like
this as well?

No, it looks good. Please note though that patch 6/8 (dt-bindings) still
needs an Acked/Reviewed-by from the device tree maintainers.

There was a comment on it from Krzysztof.

I think, you should also set *num_buffers to be inst->fbc_buf_count for
V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE, like this:

		} else if (q->type == V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE) {
			if (*num_buffers < inst->fbc_buf_count)
				*num_buffers = inst->fbc_buf_count;

			switch (*num_planes) {
			case 1:
				...
			case 2:
				...
			case 3:
				...
			}
		}

The reason for that is if fbc_buf_count is greater than initial num_buffers,
wave5_vpu_dec_job_ready() wouldn't allow to invoke wave5_vpu_dec_device_run()

Here is a part of the log of described situation:

Altering num_buffers solves the issue for me.

BTW I'm currently tinkering with your patchset on another C&M IP and would be
gratefull if you Cc me in the future versions of the patchset, if any.

I was able to reproduce this issue by requesting a small number of buffers
on the CAPTURE queue that was less than inst→fbc_buf_count. When this happens,
wave5_vpu_dec_job_ready() fails here:
(v4l2_m2m_num_dst_bufs_ready(m2m_ctx) < (inst->fbc_buf_count - 1)

I also tested your suggestion to set the *num_buffers to  inst→fbc_buf_count
in queue_setup() and it seems to be working well, thanks for this.

I've been working on ways to improve testing for stateful decoders so
I'm curious how you found this issue?

With fluster tests that we use, gstreamer seems to be calculating correct number of
CAPTURE buffers to request, so we wouldn't see this.

Yes, sorry for missing you on v13, thanks for taking the time to review.

I use v4l2-ctl and ffmpeg for testing the decoder.

The first time I've encountered the discussed issue was when v4l2-ctl was
able to decode one file but not the other with bigger resolution.

For v4l2-ctl command line will look like this:
v4l2-ctl --stream-from src-file.h265 --stream-to out-file.yuv --stream-mmap --stream-out-mmap

For ffmpeg command line will look like this:
ffmpeg -c:v hevc_v4l2m2m -i src-file.h265 -fps_mode passthrough out-file.yuv

Also for ffmpeg there are options -num_output_buffers and -num_capture_buffers 
to set initial numbers of buffers in OUTPUT and CAPTURE queues, by
default they are set to 20 or so.
