Subject: [RFC 07/12] omap: mcbsp: Get rid of remaining is_omap tests
Date: Fri,  1 Jul 2011 11:52:31 +0300	[thread overview]
Message-ID: <1309510356-27147-8-git-send-email-jhnikula@gmail.com> (raw)
In-Reply-To: <1309510356-27147-1-git-send-email-jhnikula@gmail.com>

We can get rid of remaining is_omap tests in the driver by using
mcbsp_config_type that is set in omap hwmod data for 2430, 34xx and 44xx.
