From 4b90aaeb56103bf80223315964d1ce1b79422a9c Mon Sep 17 00:00:00 2001 From: Nikola Cornij Date: Tue, 23 Jul 2019 16:38:02 -0400 Subject: [PATCH 3425/4256] drm/amd/display: Remove 4:2:2 DSC support [why] If DSC is available, a higher picture quality is achieved by using DSC with 4:4:4 format. Using 4:2:2 instead does not offer any benefit and would only introduce loss of quality. Removing it reduces maintenance and testing effort.
