+Subject: [PATCH 3/3] drm: xilinx: Fix DPMS transition to on
+
+Fix the issues where the VTC is reset (losing its timing config).
+
+Also fix the issue where the plane destroys its DMA descriptors and
+marks the DMA channels as inactive but never recreates the descriptors
+and never updates the active state when turning DPMS back on.

+Upstream-Status: Pending [This is a workaround]
