Message-Id: <1316557787-14935-1-git-send-email-ben@bwidawsk.net> Date: Tue, 20 Sep 2011 15:29:47 -0700 From: Ben Widawsky <ben@...dawsk.net> To: intel-gfx@...ts.freedesktop.org Cc: Ben Widawsky <ben@...dawsk.net>, linux-kernel@...r.kernel.org, Dave Airlie <airlied@...hat.com>, Keith Packard <keithp@...thp.com> Subject: [PATCH 1/2] drm: Add Panel Self Refresh DP addresses Add the addresses and definitions I care about for Panel Self Refresh, as documented in the eDP spec. I'm sending these out before some other patches because this should be a fairly simple one to get upstream and not require too much fuss (where the others may have some fuss). This file is a mess with white spacing. I tried to stay consistent with the surrounding code.
