We could use a better description of the format here. IIRC there is
10bits of actual data contained in each 16bits. So there should be a
proper comment explaning in which way the bits are stored.
It is a little hard to describe P010, which leaves a problem cpp
information in the new patches.
Also I have no idea how to draw the byte-order table the rst document
for v4l2.
