Subject: ASoC: omap-mcbsp: Support SND_SOC_DAIFMT_CBM_CFS for omap3/4
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6e20b0d760759fd8c90a7b6ccfd6662e3edb94ed;p=linux-beck.git

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.
