Note that DMA engine drivers are not responsible for unmapping the buffers when the transfer completes - that is the responsibility of the caller. The automatic buffer unmapping is required for the async_tx APIs and offload APIs.
In dw_dmac, it is only done for slave transfers. Is this Okay ?? -- viresh
