Should the pixel data be +transported over a serial bus, the media bus pixel code that describes a +parallel format that transfers a sample on a single clock cycle is used. For +instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used +on parallel busses for transferring an 8 bits per sample BGR data, whereas on +serial busses the data in this format is only referred to using +MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single +way to transport that format on the serial busses.
