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. | |

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. | |
