Subject: [PATCH v2 2/9] ARM: OMAP: mcbsp: Enable FIFO use for OMAP2430
Date: Mon, 13 Aug 2012 17:22:41 +0300	[thread overview]
Message-ID: <1344867768-26335-3-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1344867768-26335-1-git-send-email-peter.ujfalusi@ti.com>

On OMAP2430 all McBSP ports have 128 word long buffer, enable the use of
the FIFO for the audio stack.
