From 21e8331c687fcd73a65ed60a848eaa1e6dc3b157 Mon Sep 17 00:00:00 2001
From: Andrew Jiang <Andrew.Jiang@amd.com>
Date: Mon, 6 Nov 2017 15:53:36 -0500
Subject: [PATCH 2740/4131] drm/amd/display: Loosen plane_info and scaling_info
checks
Make it so that differing dcc and plane size fields don't necessarily
result in a full update, along with upscaling modes. This allows us to
save some unnecessary full updates.
