From 11347c2a116f36b95d6cc3b315a1f269da6d42a0 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Mon, 17 Feb 2014 17:20:21 +0100
Subject: [PATCH] ARM: sun4i: dt: Fixup mmc bindings
1) Now that we're no longer overriding the caps set by mmc_of_parse we need
to set cd-inverted for our card detection to work.
2) Now that we no longer claim UHS modes support we will never use any DDR
modes, so drive-strength 2 is enough for the mmc data pins.
