Subject: [PATCH 10/17] mmc: tmio: add .enable_dma on tmio_mmc_data
Date: Tue, 13 Jan 2015 04:59:05 +0000 [thread overview]
Message-ID: <87fvbfuvgd.wl%kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87twzvuvl1.wl%kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Some controllers need DMA special register/setting.
This patch adds new .enable_dma callback for it.
