018:  * These pixel codes uniquely identify data formats on the media bus. Mostly
019:  * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
020:  * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
021:  * data format is fixed. Additionally, "2X8" means that one pixel is transferred
022:  * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
023:  * transferred over the bus: "LE" means that the least significant bits are
024:  * transferred first, "BE" means that the most significant bits are transferred
025:  * first, and "PADHI" and "PADLO" define which bits - low or high, in the
026:  * incomplete high byte, are filled with padding bits.
027:  *
028:  * The pixel codes are grouped by type, bus_width, bits per component, samples
029:  * per pixel and order of subsamples. Numerical values are sorted using generic
030:  * numerical sort order (8 thus comes before 10).
031:  *
032:  * As their value can't change when a new pixel code is inserted in the
033:  * enumeration, the pixel codes are explicitly given a numerical value. The next
034:  * free values for each category are listed below, update them when inserting
035:  * new pixel codes.
