Subject: [PATCH 4/7] ARM: SAMSUNG: Update to use PL330-DMA driver
Date: Mon,  4 Jul 2011 21:18:32 +0900	[thread overview]
Message-ID: <1309781915-31549-5-git-send-email-kgene.kim@samsung.com> (raw)
In-Reply-To: <1309781915-31549-1-git-send-email-kgene.kim@samsung.com>

From: Boojin Kim <boojin.kim@samsung.com>

This patch adds to support PL330-DMA driver on DMADEVICE. Currently
S3C-DMA(PL080) is used for S3C24XX and S3C64XX and S3C-PL330-DMA has
been used for S5P SoCs. So this patch changes S3C-PL330-DMA to just
PL330-DMA for use generic DMA driver for S5P SoCs.
