Documentation/userspace-api/media/v4l/subdev-formats.rst states: "The media bus pixel codes document parallel formats. 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." Some MIPI CSI receivers strictly obey this definition and declare support for only *1X_* formats. Hence, complement the supported media bus formats with their 1X16 versions (currently applicable to yuyv, uyvy) to enhance interoperability with CSI receivers.
