From 57b9daa0e18167e8ba449bc236c3f4a755dd1833 Mon Sep 17 00:00:00 2001 From: Vikram Pandita Date: Fri, 28 Aug 2009 11:24:11 -0700 Subject: [PATCH] OMAP3: MMC: Add mux for pins For OMAP3 add MMC1 MMC2 pin mux MMC3 mux is not added as there are multiple configurations possible, so the muxing is left to be done in board file.
