Subject: [PATCH 4.4 36/41] dmaengine: mmp-pdma: add number of requestors
Date: Tue, 3 Oct 2017 14:21:37 +0200 [thread overview]
Message-ID: <20171003114222.537674588@linuxfoundation.org> (raw)
In-Reply-To: <20171003114219.900672076@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
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.
