Also many raw bayer formats contain padding bits to align pixels to byte boundaries. We haven't had a situation where we'd have the same amount of information per pixel on a pixel format with and without padding. The definition of those formats does not require the padding bits to be zero, but in practice they always are. How about the dm series of chips; are the bits always zero?

How about the dm series of chips; are the bits always zero? The OMAP 3 ISP spec doesn't specify that either AFAIR but in practice the ISP only writes zeros there. I agree that there are Bayer formats which require some padding in varying degrees. The bits I have observed are always zero. We could take that separately as I believe this (YDYC) is not directly connected with that. If you are wondering if D is zero, I think it depends on the implementation - it could be zero or the same C used previously. But safe to call it D-dummy. Can we have your ACK on this?
