18  * These pixel codes uniquely identify data formats on the media bus. Mostly
19  * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
20  * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
21  * data format is fixed. Additionally, "2X8" means that one pixel is transferred
22  * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
23  * transferred over the bus: "LE" means that the least significant bits are
24  * transferred first, "BE" means that the most significant bits are transferred
25  * first, and "PADHI" and "PADLO" define which bits - low or high, in the
26  * incomplete high byte, are filled with padding bits.
27  *
28  * The pixel codes are grouped by type, bus_width, bits per component, samples
29  * per pixel and order of subsamples. Numerical values are sorted using generic
30  * numerical sort order (8 thus comes before 10).
31  *
32  * As their value can't change when a new pixel code is inserted in the
33  * enumeration, the pixel codes are explicitly given a numerical value. The next
34  * free values for each category are listed below, update them when inserting
35  * new pixel codes.
