HDMI 2.0 monitors may not support SCDC and still be able to accept VICs above 63. Use multiple EDID capbilities to determine if the SINK is actually an HDMI 2.0 device. The QD980B HDMI 2.0 Analyzer generates unique EDIDs during CTS tests that don't contain a HDMI Forum VSDB if the block is not used during the test. The current HDMI AVI infoframe code only uses the SCDC supported information in the HDMI Forum VSDB to determine if the sink is HDMI 2.0. This patch adds a check for YCbCr420 present in the EDID supported formats as well as the existing SCDC supported check. HDMI 2.0 CTS HF1-51 test fails on the QD980B.

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.
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.
