The VOP in Rockchip SoCs that support YUV planes also support swapping of the U and V elements. Supporting the swapped variants, especially NV21, would be beneficial for multimedia applications, as the hardware video decoders only output NV21, and supporting this pixel format in the display pipeline would allow the decoded video frames to be output directly. Add support for this to support the various formats that have U/V swapped.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
