Please reword, things seems a little reverse, say what you are doing, and then
what is used to do it. This cover should include some level of tests report,
v4l2-compliance (hopefully unchanged) and fluster results (ideally with
regression testing on lets say MT8195, since a driver rewrite is not a little
affaire).

This seems to have stalled at v2, is there an update coming ?
