From d736ebea1cc335e89643656c3db33f5df55ffb16 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 25 Oct 2011 03:14:00 +0000 Subject: [PATCH] mx51evk: Use GPIO API for configuring the IOMUX GPIO API provides mxc_request_iomux function for setting the IOMUX mode. Use this function instead of directly writing to the IOMUX register.
