Those pixel formats mainly comes from Gstreamer and ffmpeg. Currently, the VOP(video output mixer) found on RK3288 and future support those 10 bits pixel formats are input. Also the decoder on RK3288 could use them as output.
The fourcc is not enough to store the endian information for those pixel formats in v4l2, as it doesn't have a flag like drm does. I have not met the usage of those 16 bits per-channel format, it is a very large color range, even the DSLR only use 12 bits.
