Nicholas Kazlauskas 6c0984d53b drm/amd/display: Raise dispclk value for dce_update_clocks
[Why]

The DISPCLK value was previously requested to be 15% higher for all
ASICS that went through the dce110 bandwidth code path. As part of a
refactoring of dce_clocks and dce110 set_bandwidth this was removed
for power saving considerations.

This changed caused corruption under certain display configurations.
Originally thought to be Vega specific, it was also observed on Polaris.

[How]

The 15% is brought back but its placement differs from the original
patch. This boost should only be enable while DFS bypass is inactive.

This (like the Vega patch) is also a workaround that should be
removed after the root cause is identified.

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.
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.
