Subject: [PATCH v2 10/10] ASoC: mrst_machine: add initial config to machine driver
Date: Fri, 06 May 2011 13:46:49 +0800 [thread overview]
Message-ID: <20110506054649.26312.81715.stgit@localhost> (raw)
In-Reply-To: <20110506053852.26312.79083.stgit@localhost>
On Moorestown, DMIC's output is set to PCM2 mono.
And the Moorestown uses MIC2 pseudo-differential configuration.
