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?
