From 16a29dd3bb18ea23d9676e6a3b1c6464dba620c3 Mon Sep 17 00:00:00 2001 From: Andrew Jiang Date: Tue, 21 Nov 2017 15:59:42 -0500 Subject: [PATCH] drm/amd/display: Refine update flags usage in update_dchubp_dpp - Only update DPP clock if it's a full update. - Program viewport on position change. This caused SLS regressions.
