From 7324907082b94679fe57ba0067c1079a03cbfd89 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Tue, 3 Sep 2013 14:57:52 +0200 Subject: [PATCH] arm:mmc:goni/exynos: Fix wrong mmc base register devices offset. On s5pc1xx mmc devices offset is multiply of 0x100000, wrong value was 0x10000. Register offset always points to mmc 0 before this change. Add macro definition of mmc dev register offset to s5pc1xx and exynos mmc.
