4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Jarzmik <robert.jarzmik@xxxxxxx>
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.
