Fangzhi Zuo 5759f38a63 drm/amd/display: HDMI remote sink need mode validation for Linux
[ Upstream commit 95d620adb48f7728e67d82f56f756e8d451cf8d2 ]

[Why]
Currently mode validation is bypassed if remote sink exists. That
leads to mode set issue when a BW bottle neck exists in the link path,
e.g., a DP-to-HDMI converter that only supports HDMI 1.4.

Any invalid mode passed to Linux user space will cause the modeset
failure due to limitation of Linux user space implementation.

[How]
Mode validation is skipped only if in edid override. For real remote
sink, clock limit check should be done for HDMI remote sink.

Have HDMI related remote sink going through mode validation to
elimiate modes which pixel clock exceeds BW limitation.

README

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.
