+Subject: [PATCH] drm/vc4: Attach margin props to the HDMI connector
+
+Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
+
+Now that the plane code takes the margins setup into account, we can
+safely attach margin props to the HDMI connector.
+
+We also take care of filling AVI infoframes correctly to expose the
+top/botton/left/right bar.
+
+Note that those margin props match pretty well the
+overscan_{left,right,top,bottom} properties defined in config.txt and
+parsed by the VC4 firmware.
