Tony Cheng 26eae6def7 drm/amd/display: fix workaround for incorrect double buffer register for DLG ADL and TTU
[ Upstream commit 85e148fb963d27152a14e6d399a47aed9bc99c15 ]

[Why]
these registers should have been double buffered. SW workaround we will have SW program the more aggressive (lower) values
whenever we are upating this register, so we will not have underflow at expense of less optimzal request pattern.

[How]
there is a driver bug where we don't check for 0, which is uninitialzed HW default.  since 0 is smaller than any value we need to program,
driver end up with not programming these registers

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.
