Dave Stevenson ec848ec081 drm/vc4: hdmi: Add CSC for BT601/709/2020 limited and full range output
The HVS always composes in the RGB domain, but there is a colourspace
conversion block on the output to allow for sending YCbCr over the
HDMI interface.
The colourspace on that link is configurable via the "Colorspace"
property on the connector, and that updates the infoframes. There
is also selection of limited or full range based on the mode selected
or an override.

Add code to update the CSC as well so that the metadata matches the
image data.

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.
