Subject: [PATCH 1/5] mmc: tmio: name 0xd8 as CTL_DMA_ENABLE
Date: Mon, 20 Jun 2011 23:00:08 +0000	[thread overview]
Message-ID: <1308610812-3479-2-git-send-email-horms@verge.net.au> (raw)
In-Reply-To: <1308610812-3479-1-git-send-email-horms@verge.net.au>

This reflects at least the current usage of this register
and I think it improves the readability of the code ever so slightly.
