[RFC][PATCH 1/2] dma: imx-sdma: Add device to device support

2014-06-13 Thread Nicolin Chen
This patch adds DEV_TO_DEV support for i.MX SDMA driver to support data tranfer between two peripheral FIFOs. The per_2_per script requires two peripheral addresses and two DMA requests. So this patch also adds them into private structure. Signed-off-by: Nicolin Chen --- drivers/dma/imx-sdma.c
