These formats are compressed 12-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_SBGGR12P V4L2_PIX_FMT_SGBRG12P V4L2_PIX_FMT_SGRBG12P V4L2_PIX_FMT_SRGGB12P Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

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.
|
