From f6281dbe4a92fe7d6758853d8db5f53a67bc9709 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 4 Apr 2013 14:37:57 +0900 Subject: [PATCH] ARM: S3C64XX: Clear DMA flags on channel request This patch clears the DMA flags when a DMA channel is requested. This is necessary because otherwise the channel may inherit incompatible settings from its last usage.
