[RESEND,media] v4l2: define V4L2_PIX_FMT_NV16M and V4L2_PIX_FMT_NV24M pixel formats
Commit Message
Define the two new V4L2_PIX_FMT_NV16M (4:2:2 two-buffers) and V4L2_PIX_FMT_NV24M (4:4:4 two-buffers)
pixel formats, the non-contiguous variants of the existing V4L2_PIX_FMT_NV16 and V4L2_PIX_FMT_NV24 formats.
Existing h/w IPs, such as decoders, operate on such separate luma and chroma buffers.

We only add new stuff at API when a driver is using, in order to avoid overriding the
Kernel with unused stuff. So, please submit this patch when you're ready to submit
the driver that is using it.
Also, in the particular case of newer pixel formats, it may make sense to submit
a patch to v4l-utils, if the new format(s) is(are) the only one(s) available for
userspace to retrieve the data.
Thanks,
Mauro

Yes indeed, that would be a second goal, as we'd need to also update
the v4l-utils libs to also recognize such formats.
