Maybe we should also rewrite that code a little and not use

 163 +                       omap_mux_set_gpio(OMAP_MUX_MODE7, 154);

because it assumes that the twl is connected in a specific way.

AFAIK, any OMAP McBSP [DAI] exports a function to High-Z the interface
which is intended by this code line.

It is

int snd_soc_dai_set_tristate(struct snd_soc_dai *dai, int tristate);

defined in linux/sound/soc-dai.h

But I know how to access the relevant DAI interface at this code location...
