From c283e41ef32442f41e7180f9bb1c5aedf9255bfe Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Mon, 15 Feb 2016 21:57:46 +0100 Subject: [PATCH] dmaengine: mmp-pdma: add number of requestors 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.
