Subject: [PATCH] spi: Compatibility with direction which is used in samsung DMA operation
Date: Sat, 10 Mar 2012 09:48:46 +0900 [thread overview]
Message-ID: <003801ccfe57$8ccff2f0$a66fd8d0$%kim@samsung.com> (raw)
I found that there are two kind of direction type.
First one is dma_data_direction defined in include/linux/dma-direction.h.
It is used for parameter of dma_map/unmap_single in spi-s3c64xx.
The other one is dma_transter_direction defined in include/linux/dmaengine.h.
It is used for direction of samsung DMA operation
(arch/arm/plat-samsung/dma-ops.c).
This patch is just some changes to use direction defines
which is used in samsung DMA operation.
