17  * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
18  * data format is fixed. Additionally, "2X8" means that one pixel is transferred
19  * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
20  * transferred over the bus: "LE" means that the least significant bits are
21  * transferred first, "BE" means that the most significant bits are transferred
22  * first, and "PADHI" and "PADLO" define which bits - low or high, in the
23  * incomplete high byte, are filled with padding bits.
