* dmaengine: Add driver for TI DMA crossbar on DRA7xPeter Ujfalusi2015-05-141-0/+188
The DRA7x has more peripherals with DMA requests than the sDMA can handle: 205 vs 127. All DMA requests are routed through the DMA crossbar, which can be configured to route selected incoming DMA requests to specific sDMA request.
