Any new feedback after the v2 for this patch? Or for the entire patch
set?

The status so far is:
Patch #1 got Reviewed-by: Paul Kocialkowski <paul.kocialkowski@bootlin.
com>
Patch #2 got no feedback.
Patch #3 got Reviewed-by: Rob Herring <robh@xxxxxxxxxx>
Patch #4 is at v2, after fixing v4l2-compliance streaming tests, thanks
Hans Verkuil for feedback. There was more feedback from Ezequiel Garcia
related to common JPEG code, I tried using Philipp Zabel's v4l2 JPEG
helpers patch, but I cannot use it "as-is", I'm expecting the next
version.
Patch #5 got no feedback

For the reference, this is the latest output from v4l2-compliance:

./v4l2-compliance --device /dev/video1 -s
v4l2-compliance SHA: 6c415a11fceb32067cdb5c2e33f90dbf018182a4, 64 bits
