Subject: [PATCH 4/4 v2] ARM: mach-shmobile: add SCIFA and SCIFB DMA slave
Date: Sun, 23 May 2010 16:39:24 +0000	[thread overview]
Message-ID: <Pine.LNX.4.64.1005231836090.3571@axis700.grange> (raw)
In-Reply-To: <Pine.LNX.4.64.1005231820190.3571@axis700.grange>

SH7372 can use DMA with the SCI serial driver. Add required slave IDs and slave
descriptors.
