From 10603caacf599297c7da0c4f4db440d015b8131a Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 26 Aug 2013 19:51:06 -0300 Subject: [PATCH] drm/i915: Apply the force-detect VGA w/a to Valleyview It appears that Valleyview shares its VGA encoder with more recent siblings and requires the same forced detection cycle after a hardware reset before we can rely on hotplugging.
