+Subject: dmaengine: mmp-pdma: add number of requestors
+
+From: Robert Jarzmik <robert.jarzmik@free.fr>
+
+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.
