From 8b45330ad30193a6e4925ae4d36565fb817533fc Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 1 May 2017 15:37:56 +0200 Subject: [PATCH] drm/i915: Use per-connector scaling mode property None of the intel connectors can use all types of scaling modes, so only try the ones that are possible. This is another preparation for connectors towards conversion to atomic.
