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. | |
