Subject: [PATCH v2 1/4] dma: mmp_pdma: Add the #dma-requests DT property documentation
Date: Mon, 15 Feb 2016 21:27:44 +0100 [thread overview]
Message-ID: <1455568067-20203-1-git-send-email-robert.jarzmik@free.fr> (raw)
For pxa based platforms, the number of requestor lines should be
specified, so that the driver can check if the flow control should be
activated (when a requestor line is asked for) or not.
Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
---
Since v1: rename of property to #dma-requests
modify default value to 32 as suggested by Vinod
