It would be great to get ASoC driver for TWL4030 since it's the biggest
task to get ASoC audio on OMAP3 EVM. 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. Eduardo
Valentin is currently updating it.

Convention in ASoC is that only machines are shown and their entries
will then select the codec and link drivers. 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.
