12-bit packed Bayer formats

Description

These four pixel formats are packed raw sRGB / Bayer formats with 12 bits per colour. Every two consecutive samples are packed into three bytes. Each of the first two bytes contain the 8 high order bits of the pixels, and the third byte contains the four least significants bits of each pixel, in the same order.

Each n-pixel row contains n/2 green samples and n/2 blue or red samples, with alternating green-red and green-blue rows. They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR12P image:

Byte Order. Each cell is one byte.
