Can you make a list of which sysfs properties correspond to existing V4L2
format or timing fields and which are 'new'?


On the left all the current mgb4 sysfs properties (see the admin-guide doc from the patch for description), on the right v4l2 structures where they could be mapped (may not be true for all of them in the patch, I will check it and update the code in v7)
