From 4ab014655ebad342c6e7beae427c5cc0f8141d2b Mon Sep 17 00:00:00 2001

Subject: dmaengine: mmp-pdma: add number of requestors
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.
