Subject: [PATCH] ARM: shmobile: r8a7778: add USB Func DMAEngine support
Date: Wed, 11 Dec 2013 00:51:04 +0000 [thread overview]
Message-ID: <87txegnrbf.wl%kuninori.morimoto.gx@gmail.com> (raw)
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
HPB-DMAC has 2 channel for USB Func (= D0/D1)
D0 is used as Tx, D1 is used as Rx on this patch
Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

BockW board will use this patch, but it needs
HPB-DMAC fixup patches merge.
I will send it when merged, but this patch
itself doesn't depend on HPB-DMAC fixup branch.
