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.
Laurent Pinchartdacdde72010-09-01 12:58:22 -0300[diff] [blame]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.
