Subject: [PATCH v7 2/4] dma: imx-sdma: Add new dma type for ssi dual fifo script
Date: Wed, 13 Nov 2013 22:55:25 +0800 [thread overview]
Message-ID: <5dde8bd3ac0ff25335d896fd617429aa75d0dcd6.1384352281.git.b42378@freescale.com> (raw)
In-Reply-To: <cover.1384352281.git.b42378@freescale.com>
This patch adds a new DMA_TYPE for SSI dual FIFO script, included
in SDMA firmware version 2. This script would allow SSI use dual
fifo mode to transimit/receive data without occasional hardware
underrun/overrun.
