Can you post the v4l2-compliance output? I gather that there is at least one
colorspace-related error that appears to be a v4l2-compliance bug, so I'd
like to see the exact error it gives. I'll see if I can fix it so this driver
has a clean compliance output.
I apologize that this driver probably won't make 4.14. Too much to review...
I hope to do the v7 review within a week.
Regards,
Hans
