From da883123b037dd41697058ef97df57cbe1a11643 Mon Sep 17 00:00:00 2001
From: Jun Lei <Jun.Lei@amd.com>

Subject: [PATCH 0326/2940] drm/amd/display: Add driver-side parsing for CM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Although 4 unique register values exist for gamma modes, two are
actually the same (the two RAMs) It’s not possible for caller to
understand this HW specific behavior, so some parsing is necessary
in driver
