Subject: dmaengine: mmp-pdma: add number of requestors
From: Robert Jarzmik <[email protected]>
commit c283e41ef32442f41e7180f9bb1c5aedf9255bfe upstream.
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.
