+From 30dd82d785715b2ed52a5079595ffcd2ec1f728d Mon Sep 17 00:00:00 2001
+From: Eric Anholt <eric@anholt.net>
+Date: Mon, 14 Jan 2019 14:47:57 -0800
+Subject: [PATCH] drm/v3d: Hook up the runtime PM ops.
+
+In translating the runtime PM code from vc4, I missed the ".pm"
+assignment to actually connect them up. Fixes missing MMU setup if
+runtime PM resets V3D.
+
+Signed-off-by: Eric Anholt <eric@anholt.net>
+(cherry picked from commit ca197699af29baa8236c74c53d4904ca8957ee06)
