Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Currently the encoder enables the rate control algorithms if the bitrate
control is non-zero. Implement the V4L2_CID_MPEG_VIDEO_FRAME_RC_ENABLE
and V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE controls to allow userspace to
choose frame-level or macroblock-level rate control updates, or to
explicitly disable rate control. Both controls are initially enabled to
keep the current behavior.

When decoding using the CODA internal rotator (for example NV12
capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19)
is written into the DEC_PIC_ROT_INDEX register. At least with firmware
version 3.1.1 this causes CODA hangups as soon as the register value
reaches 32. Instead, always write CODA_MAX_FRAMEBUFFERS.

If reordering is not enabled, the last decoded frame has to be the last

If there is still a buffer pending, mark it as the last buffer. It will
create a meta that is flagged as last when the buffer is copied into the
bitstream ring buffer. If there are no more buffers pending, find the
last bitstream meta and mark it as last. If there is no bitstream meta
either, wake up the capture queue as there will be no more decoded
frames.

or it might still contain unread data if the previous decoder stop

If the first buffer contains only headers, the sequence initialization
command fails. On CodaHx4 the buffer must be padded to at least 512
bytes, on CODA960 it seems to be enough to just repeat the sequence and
extension headers (MPEG-2) or the VOS and VO headers (MPEG-4) once for
for sequence initialization to succeed without further bitstream data.
On CodaHx4 the headers can be repeated multiple times until the 512 byte
mark is reached.
A similar issue was solved for h.264 by padding with a filler NAL in
commit 0eef89403ece ("[media] coda: pad first h.264 buffer to 512
bytes").

This commit clears the interrupt reason (INT_REASON) register
on the interrupt handler. Without this clearing, the CODA hardware
has been observed to get completely stalled on CODA980 variants,
requiring a pretty deep hardware reset.
The datasheet specifies that the INT_REASON register is set
by the CODA hardware, and should be cleared by the host.
While the CODA versions that are currently supported by this driver
don't seem to need this change, it's a really small change,
so it seems a wise thing to do to avoid hitting some
rare race-condition in the hardware.

The ringbuffer used to hold the bitstream is very conservatively sized,
as keyframes can get very large and still need to fit into this buffer.
This means that the buffer is way oversized for the average stream to
the extend that it will hold a few hundred frames when the video data
is compressing well.
The current strategy of queueing as much bitstream data as possible
leads to large delays when draining the decoder. In order to keep the
drain latency to a reasonable bound, try to only queue a full reorder
window of buffers. We can't always hit this low target for very well
compressible video data, as we might end up with less than the minimum
amount of data that needs to be available to the bitstream prefetcher,
so we must take this into account and allow more buffers to be queued
in this case.
