Subject: [PATCH 1/2] ASoC: tlv320aic32x4: always enable dividers
Date: Wed, 18 Jan 2012 11:48:58 +0100	[thread overview]
Message-ID: <1326883739-8148-1-git-send-email-w.sang@pengutronix.de> (raw)

Dividers (such as MDAC) are always needed, independent of the codec
being I2S master or slave. Needed on a custom board where the codec has
to be slave.
