@ -9,18 +9,22 @@ This patch was originally submitted by Jelle van der Waa. Martin Kelly
modified it to compile on the latest kernel, fixed up some review
comments from Maxime Ripard, and re-tested the patch.
The patch has been reworked to add back eMMC support which has been left
out at the last backport.
