From a9e23519f99948f545d6a48a8f594a8773f36696 Mon Sep 17 00:00:00 2001 From: Yongqiang Sun Date: Fri, 17 Nov 2017 10:44:15 -0500 Subject: [PATCH 2899/4131] drm/amd/display: Disable plane right after disconnected HDR display playing video underflow is observed when switching to full screen due to program a lower watermark right after unlock otg. Instead of disable plane in next flip coming, if there is a plane disconnected, after otg unlock wait for mpcc idle and disable the plane, then program watermark. So there is enough warter mark to make sure current frame data pass through.
