/*
* 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.
