Subject: [PATCH 0/2] Improve V4L2 M2M job scheduler

From: "Hsia-Jun(Randy) Li" <randy.li@...aptics.com>

The first patch is an old patch, I resend it again.
I want to make the work thats parses the bitstream
to extract the sequence information or video resolution
as a part of V4L2 schedule. Such a work would also
consume the device's resources likes remote CPU
time.

Although reuse a flag which no current driver may
not be a good idea. I could add a new flag for that
if people like that.

The second is a patch offering a generic solution
for tracking buffers which have been pushed to
hardware(or firmware). It didn't record which buffer
that hardware(firmware) still holds for future
decoding(likes the reference buffer), while it
has been sent to the user(dequeue). We may need
a flag for this work.

  media: v4l2-mem2mem: add a list for buf used by hw

Randy Li (1):
  media: v4l2-mem2mem: allow device run without buf
