Thanks Maxime for this great series !
I've tested this series successfully on STM32 platform, I had a
regression on JPEG capture linked to revisit of clocking, but easy to fix.
I had another problem claimed by v4l2-compliance on format tests:
v4l2-test-formats.cpp(961): Video Capture: S_FMT(G_FMT) != G_FMT
this was more tricky to fix, it is linked to changes around framerate
handling.
See my further comments in corresponding patchsets.
Best regards,
Hugues.
