The client would set the xfer_direction and dmac would interpret as

enum xfer_direction {
MEM_TO_MEM, -> Async/Memcpy mode
MEM_TO_DEV, -> Slave mode & From Memory to Device
DEV_TO_MEM, -> Slave mode & From Device to Memory
DEV_TO_DEV, -> Slave mode & From Device to Device
How could it get any cleaner?
