[WHY] The source device outputs a full RGB signal, but TV may be set to use limited RGB. The mismatch in color range leads to a degradation in image quality. Display driver should have the ability to switch between the full and limited RGB to match TV's settings. [HOW] Add support of the linux DRM "Broadcast RGB" property, which indicates the Quantization Range (Full vs Limited) used. User space can set this property to be "Automatic", "Full" or "Limited 16:235" to adjust the output color range.

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 reStructuredText 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.
