Each sample is stored in a 16-bit word, with two 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_SBGGR14 image: ++ ++**Byte Order.** ++Each cell is one byte, the two most significant bits in the high bytes are ++zero. ++ ++ ++ ++.. flat-table:: ++ :header-rows: 0 ++ :stub-columns: 0 ++ :widths: 2 1 1 1 1 1 1 1 1 ++ ++ ++ * - start + 0: ++ - B\ :sub:`00low` ++ - B\ :sub:`00high` ++ - G\ :sub:`01low` ++ - G\ :sub:`01high` ++ - B\ :sub:`02low` ++ - B\ :sub:`02high` ++ - G\ :sub:`03low` ++ - G\ :sub:`03high` ++ * - start + 8: ++ - G\ :sub:`10low` ++ - G\ :sub:`10high` ++ - R\ :sub:`11low` ++ - R\ :sub:`11high` ++ - G\ :sub:`12low` ++ - G\ :sub:`12high` ++ - R\ :sub:`13low` ++ - R\ :sub:`13high` ++ * - start + 16: ++ - B\ :sub:`20low` ++ - B\ :sub:`20high` ++ - G\ :sub:`21low` ++ - G\ :sub:`21high` ++ - B\ :sub:`22low` ++ - B\ :sub:`22high` ++ - G\ :sub:`23low` ++ - G\ :sub:`23high` ++ * - start + 24: ++ - G\ :sub:`30low` ++ - G\ :sub:`30high` ++ - R\ :sub:`31low` ++ - R\ :sub:`31high` ++ - G\ :sub:`32low` ++ - G\ :sub:`32high` ++ - R\ :sub:`33low` ++ - R\ :sub:`33high` +--- a/drivers/media/v4l2-core/v4l2-ioctl.c ++++ b/drivers/media/v4l2-core/v4l2-ioctl.c +@@ -1298,6 +1298,10 @@ static void v4l_fill_fmtdesc(struct v4l2 + case V4L2_PIX_FMT_SGBRG12P: descr = "12-bit Bayer GBGB/RGRG Packed"; break; + case V4L2_PIX_FMT_SGRBG12P: descr = "12-bit Bayer GRGR/BGBG Packed"; break; + case V4L2_PIX_FMT_SRGGB12P: descr = "12-bit Bayer RGRG/GBGB Packed"; break; ++ case V4L2_PIX_FMT_SBGGR14: descr = "14-bit Bayer BGBG/GRGR"; break; ++ case V4L2_PIX_FMT_SGBRG14: descr = "14-bit Bayer GBGB/RGRG"; break; ++ case V4L2_PIX_FMT_SGRBG14: descr = "14-bit Bayer GRGR/BGBG"; break; ++ case V4L2_PIX_FMT_SRGGB14: descr = "14-bit Bayer RGRG/GBGB"; break; + case V4L2_PIX_FMT_SBGGR14P: descr = "14-bit Bayer BGBG/GRGR Packed"; break; + case V4L2_PIX_FMT_SGBRG14P: descr = "14-bit Bayer GBGB/RGRG Packed"; break; + case V4L2_PIX_FMT_SGRBG14P: descr = "14-bit Bayer GRGR/BGBG Packed"; break; +--- a/include/uapi/linux/videodev2.h ++++ b/include/uapi/linux/videodev2.h +@@ -666,6 +666,10 @@ struct v4l2_pix_format { + #define V4L2_PIX_FMT_SGBRG12P v4l2_fourcc('p', 'G', 'C', 'C') + #define V4L2_PIX_FMT_SGRBG12P v4l2_fourcc('p', 'g', 'C', 'C') + #define V4L2_PIX_FMT_SRGGB12P v4l2_fourcc('p', 'R', 'C', 'C') ++#define V4L2_PIX_FMT_SBGGR14 v4l2_fourcc('B', 'G', '1', '4') /* 14 BGBG..
