* dmaengine: xgene-dma: Fix the resource map to handle overlappingRameshwar Prasad Sahu2015-07-311-1/+1
| | | | | | | | | There is an overlap in dma ring cmd csr region due to sharing of ethernet ring cmd csr region. This patch fix the resource overlapping by mapping the entire dma ring cmd csr region.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 request line of the DMA controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DMA routers are transparent devices used to mux DMA requests from peripherals to DMA controllers. They are used when the SoC integrates more devices with DMA requests then their controller can handle. DRA7x is one example of such SoC, where the sDMA can hanlde 128 DMA request lines, but in SoC level it has 205 DMA requests. The of_dma_router will be registered as of_dma_controller with special xlate function and additional parameters. The driver for the router is responsible to craft the dma_spec (in the of_dma_route_allocate callback) which can be used to requests a DMA channel from the real DMA controller. This way the router can be transparent for the system while remaining generic enough to be used in different environments.

| * | dmaengine: mv_xor: add support for a38x command in descriptor modeLior Amsalem2015-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Marvell Armada 38x SoC introduce new features to the XOR engine, especially the fact that the engine mode (MEMCPY/XOR/PQ/etc) can be part of the descriptor and not set through the controller registers. This new feature allows mixing of different commands (even PQ) on the same channel/chain without the need to stop the engine to reconfigure the engine mode. Refactor the driver to be able to use that new feature on the Armada 38x, while keeping the old behaviour on the older SoCs.

| | * dmaengine: remove Renesas Audio DMAC peri periKuninori Morimoto2015-03-181-29/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. Audio DMAC peri peri on DMAEngine is no longer needed. remove it.
