Re: [alsa-devel] [PATCH] ASoC: omap-mcbsp: Support SND_SOC_DAIFMT_CBM_CFS for omap3/4

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.
