From 5d9df8eeacec943c9599f1cfd1069bc8cced3de6 Mon Sep 17 00:00:00 2001 From: Adrian McMenamin Date: Mon, 8 Oct 2007 05:19:36 +0900 Subject: [PATCH] sh: Fix SH-4 DMAC CHCR masking. This patch fixes the DMA cascade by masking the correct bits. Tested and working with Dreamcast PVR2 DMA. With this patch applied the existing mainline code in arch/sh/drivers/dma/dma-sh.c works, whereas before I was patching that to get round this problem.
