From 64e8867ba8098b69889c1af94997a5ba2348fb26 Mon Sep 17 00:00:00 2001 From: Ian Molton Date: Wed, 6 Jan 2010 13:51:48 +0100 Subject: mfd: tmio_mmc hardware abstraction for CNF area This patch abstracts out the CNF area code from tmio_mmc which is not present in all hardware that can use this driver. This is required so that we can support non-toshiba based hardware.
