mmp-pcm handle audio dma based on soc-dmaengine
Support mmp and pxa910

See soc-dmaengine.c. You sneed to use the library to use dmaengine.

Thanks Vinod for kind review.

Some confusion, only find sound/soc/soc-dmaengine-pcm.c.
So the driver base on the library, snd_dmaengine_pcm_open/close etc.
Replacing dma_request_channel etc.

Is it right direction?

Yes your driver should use it. See examples in other soc drivers
