As this is the third occurrence of these 2 definitions, perhaps they
should be moved to sh_pfc.h?

This is the green channel, to augment red and blue in vin_data8*?
If yes, would it make sense to have a separate vin1_data12* section,
combining them?

    I'll look into this.

    I have no idea, even after rummaging in the BT.* specs mentioned in the 
manuals. ITU-R BT.656 only describes 8- and 10-bit interfaces. Matsuoka-san, 
any idea?

    Most probably.
