I volunteered to port the sensor drivers we use with the OMAP3 to v4l2_subdev, 
implementing the missing operations/helpers/whatever on the way, but it 
somehow escaped my mind at the time that it included the bus config and data 
format operations :-)

Your RFC will be used as a starting point (actually more than a starting 
point, as there has been lots of discussions around it already). My plan is to 
reuse what's available in RFCs as-is, port the drivers, see how everything 
shatters to pieces (hopefully it won't :-)), and post RFCs to fix the problems 
if required. You will of course be included in the discussion.
