Changed it to V4L2_MBUS_FMT_UYVY8_2X8 Does this mean that the old 2X10 format code is no longer used? This change basically not just sets a new default format code but removes the old format code as well. Is that really intended? If someone else is using that old format already, then this change may well break his board.
