From 95c7348d948dc4832434ddfaeba804ac14732f02 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Tue, 21 Jun 2011 08:00:08 +0900 Subject: [PATCH] mmc: tmio: name 0xd8 as CTL_DMA_ENABLE This reflects at least the current usage of this register and I think it improves the readability of the code ever so slightly.
