[PATCH 01/13] media: coda: move register debugging to coda_debug level 3

[Philipp Zabel]

This allows to use coda_debug level 2 for verbose but not quite as
verbose debug logging. Register access level logging is of limited
use anyway, as this includes busy polling of status bits.

[PATCH 04/13] media: coda: improve decoder job finished debug message

[Philipp Zabel]

Print a single line containing the following information:
 - which frame was decoded, including its type,
 - if no frame was decoded, the reason (code) why
 - which decoded frame was returned, copied out by either rotator or VODA,
 - if no frame was returned, the reason (code) why, and
 - the output queue sequence number, which is only useful in case
   each queued coded buffer corresponds to exactly one frame.

[PATCH 13/13] media: coda: fix unset field and fail on invalid field in buf_prepare

[Philipp Zabel]

v4l2-compliance likes to queue a buffer with field set to V4L2_FIELD_ANY
and expects it to be returned corrected to a valid field.

Follow vicodec in handling this in the buf_prepare callback.

The codec controls are grouped per codec, so it is not a good idea to add
the MPEG2-specific controls to the HEVC controls. I suggest starting a new
MPEG2 group at (V4L2_CID_MPEG_BASE + 270).

Unless you expect many more MPEG2 specific controls? The range 290-299 is
reserved for the FWHT codec, so if we start at 270, then that leaves room
for 20 controls.

Regards,

	Hans

I believe instead of this, you can just populate your buf_out_validate
like this:

static int coda_buf_out_validate(struct vb2_buffer *vb)
{
        struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb);

        vbuf->field = V4L2_FIELD_NONE;
        return 0;
}

Thanks,
Eze

This one causes a GCC error:

[PATCH v2] media: coda: add decoder MPEG-4 profile and level controls

[Philipp Zabel]

The MPEG-4 decoder firmware reports profile and level indication values
that can be used to update V4L2 MPEG-4 profile and level controls.

Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
---
Changes since v1 [1]:
 - Fix coda_decode_ctrls trying to set mpeg2_level_ctrl read-only,
   that should be mpeg4_level_ctrl.
