Subject: [PATCH 6/7] drm/i915: turn on the power well before suspending
Date: Fri, 25 Jan 2013 16:59:15 -0200 [thread overview]
Message-ID: <1359140356-4050-7-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1359140356-4050-1-git-send-email-przanoni@gmail.com>
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
Our suspend code touches a lot of registers all over the place, so we
need to enable the power well before suspending.
