+From 88bab55da9ecb7c77f35110a623f2c1dcd80b774 Mon Sep 17 00:00:00 2001
+From: Josip Pavic <Josip.Pavic@amd.com>

+Subject: [PATCH 3826/4256] drm/amd/display: define parameters for abm 2.3
+
+[Why]
+Current configuration 0 is just a placeholder, and final parameters needed.
+Also, configuration 1 is expected to emulate ABM 2.1 but is too aggressive.
+
+[How]
+Redefine configuration 0 with the finalized parameters, and increase the
+contrast gain of configuration 1 so that it properly emulates ABM 2.1.
