From d03e119c08359f9217154d6a4201689639fe29c8 Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Mon, 3 Jan 2011 19:36:25 +0900 Subject: [PATCH] ARM: S3C64XX: Clear DMA_HALT upon start The stop function sets the DMA_HALT bit, which prevents the DMA transfer to resume after stop, for example during audio PAUSE/PLAY cycle. Clear the HALT bit during start.
