Subject: [PATCH 1/4] dma: mmp_pdma: Add the #requestors DT property documentation
Date: Thu, 11 Feb 2016 22:23:15 +0100 [thread overview]
Message-ID: <1455225798-9510-2-git-send-email-robert.jarzmik@free.fr> (raw)
In-Reply-To: <1455225798-9510-1-git-send-email-robert.jarzmik@free.fr>
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.
