AFAIK TWL4030 is used also in other EVMs as well so those boards can be supported also by just adding own ASoC machine drivers for them. Currently ASoC for OMAP doesn't support yet OMAP3 but it's not very big issue to add it after low-level McBSP driver supports it.

E.g config SND_OMAP_SOC_N810 tristate "SoC Audio support for Nokia N810" depends on SND_OMAP_SOC && MACH_NOKIA_N810 select SND_OMAP_SOC_MCBSP select SND_SOC_TLV320AIC3X help Say Y if you want to add support for SoC audio on Nokia N810.

ALSA SoC for TWL4030
I'm thinking of tackling audio support for the OMAP3 EVM next. I'd like to make sure that I'm not duplicating work :-) Is anyone aware of any existing efforts to support the TWL4030 audio functionality? I've seen the TI work in the 2.6.22 kernel, but it is not an SoC driver and seems to use a different mcbsp implementation than is in the current linux-omap tree.
