+Subject: [PATCH] drm/connector: Allow creation of margin props alone
+
+Commit 6c4f52dca36f5e3e2354c30591d38e92f4657ed9 upstream.
+
+TV margins properties can only be added as part of the SDTV TV
+connector properties creation, but we might need those props for HDMI
+TVs too, so let's move the margins props creation in a separate
+function and expose it to drivers.
+
+We also add an helper to attach margins props to a connector.
