``V4L2_PIX_FMT_NV12_10BE_8L128`` is similar to ``V4L2_PIX_FMT_NV12M_10BE_8L128`` but stores
two planes in one memory.
-``V4L2_PIX_FMT_MM21`` store luma pixel in 16x32 tiles, and chroma pixels
-in 16x16 tiles. The line stride must be aligned to a multiple of 16 and the
-image height must be aligned to a multiple of 32. The number of luma and chroma
-tiles are identical, even though the tile size differ. The image is formed of
-two non-contiguous planes.

+``V4L2_PIX_FMT_MT2110T`` is one of Mediatek packed 10bit YUV 4:2:0 formats.
+It is fully packed 10bit 4:2:0 format like NV15 (15 bits per pixel), except
+that the lower two bits data is stored in separate partitions. The format is
+composed of 16x32 luma tiles, and 16x16 chroma tiles. Each tiles is 640 bytes
+long, divided into 8 partitions of 80 bytes. The first 16 bytes of the
+partition represent the 2 least significant bits of pixel data. The remaining
+64 bytes represent the 8 most significant bits of pixel data.

+Filtering out the upper part of each partitions results in a valid
+``V4L2_PIX_FMT_MM21`` frame. A partition is a sub-tile of size 16 x 4. The
+lower two bits is said to be tiled since each bytes contains the lower two
+bits of the column of for pixel matching the same index. The chroma tiles
+only have 4 partitions.
