dmaengine: dw-dmac: Custom cyclic API (Why?)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,


I am going to work with dw-dmac AHB controller and I wanted to
use SND_DMAENGINE_PCM. In order to use this, a standard DMA
driver with cyclic support is needed. I found out that dw-dmac is
capable of cyclic transfers but instead of using the DMA engine
standard cyclic API it uses a custom API. Is there any specific
reason for this? What is the effort to change the custom API to a
standard DMA engine cyclic API?


Best regards,

Jose Miguel Abreu
