Subject: [PATCH v3 2/3] omap3: beaglexm: fix DVI reset GPIO
Date: Thu, 6 Jan 2011 13:54:38 -0600 [thread overview]
Message-ID: <1294343679-10605-3-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1294343679-10605-1-git-send-email-nm@ti.com>
From: Koen Kooi <koen@beagleboard.org>
GPIO reset line for Beagle XM is different from vanilla beagle
so we populate it as part of gpio update routine.
