This should be:
depends on VIDEO_DEV && VIDEO_V4L2 && VIDEO_V4L2_SUBDEV_API
depends on SOC_DRA7XX || COMPILE_TEST

By compiling with COMPILE_TEST I found a number of compile warnings and it also
no
longer compiled due to vb2 changes. Both are fixed in the patch below.
SoB for the patch: Signed-off-by: Hans Verkuil <hans.verk...@cisco.com>
That said, I'll postpone merging this until the remainder of the vb2 split
patches
have been merged. When that's done this driver will have to be changed some
more.
BTW, I see one 'f->fmt.pix.priv = 0;' line in cal_try_fmt_vid_cap(): this can
be removed,
it's no longer needed.
Regards,
Hans
