For both BT.656 and BT.1120 video, the pixel format used by VPIF is Y/CbCr 4:2:2 in semi-planar format (Luma in one plane and Chroma in another). This corresponds to NV16 pixel format. This is documented in section 36.2.3 of OMAP-L138 Technical Reference Manual, SPRUH77A. The VPIF driver incorrectly sets the default format to V4L2_PIX_FMT_YUV422P. Fix it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
