media: v4l2: Add NV15 and NV20 pixel formats
Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for 10-bit buffers. NV15 and NV20 is 10-bit 4:2:0/4:2:2 semi-planar YUV formats similar to NV12 and NV16, using 10-bit components with no padding between each component. Instead, a group of 4 luminance/chrominance samples are stored over 5 bytes in little endian order: YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes The '15' and '20' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 8 for NV15 and 4 for NV20.
