Date: Sat, 15 Jun 2013 12:51:47 +0800 From: Qiao Zhou <zhouqiao@...vell.com> To: <djbw@...com>, <vinod.koul@...el.com>, <zhangfei.gao@...il.com>, <linux-kernel@...r.kernel.org> CC: Qiao Zhou <zhouqiao@...vell.com> Subject: [PATCH V2] dma: mmp_tdma: disable irq when disabling dma channel V2 -> V1: 1, mask dma interrupt when disable DMA channel. 2, remove patch v1. if the dma channel is disabled without interrupt masked, the interrupt status may still be set. next time when dma channel is enabled again, the old interrupt status may trigger the interrupt wrongly. we need to mask the interrupt when dma channel is disabled.
