/*
* These pixel codes uniquely identify data formats on the media bus. Mostly
* they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
* reserved, V4L2_MBUS_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 pixel codes 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 pixel code is inserted in the
* enumeration, the pixel codes are explicitly given a numerical value. The next
* free values for each category are listed below, update them when inserting
* new pixel codes.
