Subject: [PATCH] ARM: S3C64XX: Clear DMA flags on channel request
Date: Fri, 8 Mar 2013 15:53:04 +0000 [thread overview]
Message-ID: <1362757984-19249-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
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.
