-Subject: [PATCH] drm: vc4: Fix pixel-wrap issue with DVP teardown
-
-Adjust the DVP enable/disable sequence to avoid a pixel getting stuck
-in an internal, non resettable FIFO within PixelValve when changing
-HDMI resolution.
-
-The blank pixels features of the DVP can prevent signals back to
-pixelvalve causing it to not clear the FIFO. Adjust the ordering
-and timing of operations to ensure the clear signal makes it through to
-pixelvalve.
