From 9e6c82cd3e1a739ef48bf8c1decc8e7a7d8de3ac Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 14 Sep 2009 12:57:11 +0100 Subject: ARM: 5698/1: MMCI pass capabilities in platform data This makes it possible to pass down the host controller capabilities for the MMCI driver using the platform data. It also provides the capabilties for the U300 implementation as an example, and makes sure the 4bit wide mode is set if this is requested by the ios() now that we can actually set that capability for a platform.
