Subject: [PATCH] ASoC: omap-mcbsp: Support SND_SOC_DAIFMT_CBM_CFS for omap3/4
Date: Sun, 21 Jul 2013 18:24:01 +0200 [thread overview]
Message-ID: <20130721162400.GA17491@panicking> (raw)
Add SND_SOC_DAIFMT_CBM_CFS support for omap3/omap4. The patch was tested on
a pandaboard-es board connected to the pcm1792a codec. mcbspx_fsx must
configured as output and mcbspx_clkx must be configured as input.
