    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?
