* docs: uapi: media: Document Mediatek 10bit tiled formatsNicolas Dufresne2024-08-141-0/+129
| | | | | | | | | | Document V4L2_PIX_FMT_MT2110T and V4L2_PIX_FMT_MT2110R. These two formats are nearly identical, reusing MM21 format and expending it by inserting chunk of 16 bytes of lower 2 bit pixel data after each chunk of 64 bytes higher 8 bit of data.

| | | | | | | | | | | | P012 is a YUV format with 12-bits per component with interleaved UV, like NV12, expanded to 16 bits. Data in the 12 high bits, zeros in the 4 low bits, arranged in little endian order. And P012M has two non contiguous planes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MM21 has been documented through two software implementation [0] in libyuv and [2] GStreamer. This format is similar to other tiled format, though it uses uneven tile sizes. The luma tiles are 16x32 while the chroma tile have a subsampled size of 16x16. This is the uncompressed cousin of V4L2_PIX_FMT_MT21C and shares its tiling pattern and alignment.

* media: Clean V4L2_PIX_FMT_NV12MT documentationEzequiel Garcia2021-09-301-12/+13
| | | | | | | | | | | | | | | | | Add more information about V4L2_PIX_FMT_NV12MT and V4L2_PIX_FMT_NV12M_16X16, so it's clearer for driver authors and users. Also, group the two pixel formats with the other tiled formats, for clarity. Unlike the recently introduced tiled formats (V4L2_PIX_FMT_NV12_4L4, etc) these formats have remained Samsung-specific until now. Therefore, and although the NV12MT and NV12MT_16X16 nomenclatures are less clear, we are keeping them as-is.

| | | | | | | | | | | | | | This format is produced by VeriSilicon Hantro G2 and VC8000D cores. It is a simple 4x4 tiling layout in a linear way. The pixel format was introduced by GStreamer using FourCC VT12, so let's stick to it.
