Subject: [PATCH 21/22] drm/i915: add media well to VLV force wake routines
Date: Sat, 2 Feb 2013 13:56:25 +0100 [thread overview]
Message-ID: <1359809786-26434-22-git-send-email-jbarnes@virtuousgeek.org> (raw)
In-Reply-To: <1359809786-26434-1-git-send-email-jbarnes@virtuousgeek.org>
We could split this out into a separate routine at some point as an
optimization.
