Subject: [PATCH 2/3] ASoC: imx: fix burstsize for DMA
Date: Fri, 25 Mar 2011 16:51:45 +0100 [thread overview]
Message-ID: <1301068306-11997-3-git-send-email-w.sang@pengutronix.de> (raw)
In-Reply-To: <1301068306-11997-1-git-send-email-w.sang@pengutronix.de>
SSI counts in words, the DMA engine in bytes. (Wrong) factor got removed
in bf974a0 (ASoC i.MX: switch to new DMA api).
