Subject: [RFC PATCH 2/2] AM33XX: pcm051: Create custom mux file
Date: Tue, 12 Mar 2013 15:04:13 +0100	[thread overview]
Message-ID: <1363097053-25784-2-git-send-email-t.gamez@phytec.de> (raw)
In-Reply-To: <1363097053-25784-1-git-send-email-t.gamez@phytec.de>

The pcm051 has no MMC WP pin. This pin is used for a gpio and
needs to be muxed different. Created a custom mux file for
this case.
