Thanks for the review.
I'll send a new patch with the proper names:
include/uapi/linux/videodev2.h:#define V4L2_PIX_FMT_SBGGR12P
v4l2_fourcc('p', 'B', 'C', 'C')
include/uapi/linux/videodev2.h:#define V4L2_PIX_FMT_SGBRG12P
v4l2_fourcc('p', 'G', 'C', 'C')
include/uapi/linux/videodev2.h:#define V4L2_PIX_FMT_SGRBG12P
v4l2_fourcc('p', 'g', 'C', 'C')
include/uapi/linux/videodev2.h:#define V4L2_PIX_FMT_SRGGB12P
v4l2_fourcc('p', 'R', 'C', 'C')
