Subject: [PATCH v3 01/15] dmaengine: omap: Support for element mode in cyclic DMA
Date: Fri, 14 Sep 2012 15:05:44 +0300 [thread overview]
Message-ID: <1347624358-25582-2-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1347624358-25582-1-git-send-email-peter.ujfalusi@ti.com>
When src_maxburst/dst_maxburst is set to 0 by the users of cyclic DMA
(mostly audio) indicates that we should configure the omap DMA to element
sync mode instead of packet mode.
