From f301c062dcdd113bc977ae1ebc8c12232f8531a9 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Fri, 21 Jan 2011 14:11:53 +0000 Subject: dmaengine/dw_dmac: allow src/dst masters to be configured at runtime Some platforms have flexible mastering capabilities and this needs to be selected at runtime. If the platform has specified private data in the form of the dw_dma_slave then fetch the source and destination masters from here. If this isn't present, default to the previous of 0 and 1. v2: cleanup whitespace Acked-by: Hans-Christian Egtvedt Signed-off-by: Jamie Iles Signed-off-by: Dan Williams --- include/linux/dw_dmac.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/linux') diff --git a/include/linux/dw_dmac.h b/include/linux/dw_dmac.h index c8aad713a04..8014eb81054 100644 --- a/include/linux/dw_dmac.h +++ b/include/linux/dw_dmac.h @@ -52,6 +52,8 @@ struct dw_dma_slave { enum dw_dma_slave_width reg_width; u32 cfg_hi; u32 cfg_lo; + int src_master; + int dst_master; }; /* Platform-configurable bits in CFG_HI */ -- cgit v1.2.3-70-g09d2
