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. |
