| * These bus formats uniquely identify data formats on the data bus. Format 0 |
| * is reserved, MEDIA_BUS_FMT_FIXED shall be used by host-client pairs, where |
| * the data format is fixed. Additionally, "2X8" means that one pixel is |
| * transferred in two 8-bit samples, "BE" or "LE" specify in which order those |
| * samples are transferred over the bus: "LE" means that the least significant |
| * bits are transferred first, "BE" means that the most significant bits are |
| * transferred first, and "PADHI" and "PADLO" define which bits - low or high, |
| * in the incomplete high byte, are filled with padding bits. |
| * |
| * The bus formats are grouped by type, bus_width, bits per component, samples |
| * per pixel and order of subsamples. Numerical values are sorted using generic |
| * numerical sort order (8 thus comes before 10). |
| * |
| * As their value can't change when a new bus format is inserted in the |
| * enumeration, the bus formats are explicitly given a numerical value. The next |
| * free values for each category are listed below, update them when inserting |
| * new pixel codes. |
