From e1dd1afba99853083da545f632a1f7c6899ae379 Mon Sep 17 00:00:00 2001 From: Koen Kooi Date: Tue, 11 Jan 2011 17:13:36 +0000 Subject: [PATCH 02/28] omap3: beaglexm: fix DVI reset GPIO GPIO reset line for Beagle XM is different from vanilla beagle so we populate it as part of gpio update routine. This in part fixes the issue of display not functioning on beagle XM platform.
