From 07bd1a6cc7cbb3f373fbe49b204c6cde5e9155fc Mon Sep 17 00:00:00 2001 From: Juergen Beisert Date: Sat, 5 Jul 2008 10:02:49 +0200 Subject: MXC arch: Add gpio support for the whole platform This patch bases on the one from Daniel Mack. The most important change to Daniel's patch is to be more generic. This gpio routine supports at least the i.MX27 and i.MX31 processors.
