From 8d1b18d569d59c8aa95964e2e5e4c5d544928258 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 17 Jan 2012 11:05:32 +0200 Subject: OMAP: 4430SDP/Panda: add HDMI HPD gpio commit aa74274b464d4aa24703963ac89a0ee942d5d267 upstream. Both Panda and 4430SDP use GPIO 63 as HDMI hot-plug-detect. Configure this GPIO in the board files.
