dmaengine: Driver for Topcliff PCH DMA controller
Topcliff PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platforms. This adds the driver for Topcliff PCH DMA controller. The DMA channels are strictly for device to host or host to device transfers and cannot be used for generic memcpy.
