From ce48affb85601b440394e2268bec47e9e6c9e513 Mon Sep 17 00:00:00 2001
From: Sascha Hauer <s.hauer@pengutronix.de>
Date: Fri, 14 Dec 2012 10:29:36 +0100
Subject: [PATCH] ARM omap hsmmc: Fix register offset
The hsmmc module has a 0x100 offset in its register space. The real
register space size for the module is 4K, so when we register the
device with the size 4k, we have to account for the offset in the
driver, not in the resource allocation.
