15 * These pixel codes uniquely identify data formats on the media bus. Mostly
16 * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
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.
