From a017530921908bd4200e6162ed0129ceb49f98fa Mon Sep 17 00:00:00 2001
From: Andrew Jiang <Andrew.Jiang@amd.com>
Date: Wed, 6 Sep 2017 18:56:46 -0400
Subject: [PATCH 2466/4131] drm/amd/display: Force always scale chroma, set
always_scaled to false
This allows us to not always have scaling on, which causes issues with
validation and causes the text to blur slightly.
