Add a V4L2 mem-to-mem driver for Allegro DVT video IP cores as found in the EV family of the Xilinx ZynqMP SoC. The Zynq UltraScale+ Device Technical Reference Manual uses the term VCU (Video Codec Unit) for the encoder, decoder and system integration block. This driver takes care of interacting with the MicroBlaze MCU that controls the actual IP cores. The IP cores and MCU are integrated in the FPGA. The xlnx_vcu driver is responsible for configuring the clocks and providing information about the codec configuration. The driver currently only supports the H.264 video encoder.

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.
