These formats are compressed 14-bit raw bayer formats with four different
pixel orders. They are similar to 10-bit variants. The formats added by
this patch are
V4L2_PIX_FMT_SBGGR14P
V4L2_PIX_FMT_SGBRG14P
V4L2_PIX_FMT_SGRBG14P
V4L2_PIX_FMT_SRGGB14P

+ <title>Description</title>
+
+ <para>These four pixel formats are packed raw sRGB / Bayer
+ formats with 14 bits per colour. Every four consecutive colour
+ components are packed into 7 bytes. Each of the first 4 bytes
+ contain the 8 high order bits of the pixels, and the fifth, sixth
+ and seventh bytes contains the six least significant bits of each
+ pixel, in the same order.</para>
+
+ <para>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 one of these
+ formats:</para>

+ <title>Byte Order.</title>
+ <para>Each cell is one byte. The bits in subscript denote bits
+ of the sample. The bits of the cell byte can be found in
+ parentheses.
