+12-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 12 bits per
+colour. Each colour component is stored in a 16-bit word, with 4 unused
+high bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes
+are stored in memory in little endian order. They are conventionally
+described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
+of a small V4L2_PIX_FMT_SBGGR12 image:
+
+**Byte Order.**
+Each cell is one byte, the 4 most significant bits in the high bytes are
+0.
