The DMA chip has a fixed number of requestor lines used for flow control. This number is platform dependent. The pxa_dma dma driver will use this value to activate or not the flow control. There won't be any impact on mmp_pdma driver.
Haojian, Even if mmp_pdma will not be impacted, it would be good to have have your ack on this trivial patch. Cheers. -- Robert [1] The patch
