After a quick check: it needs some modification for the
New struct for the twl4030_codec, adding that to the existing
Than modification to drivers/mfd/twl4030-core.c:
Adding the audio codec as new child.
Modifying the arch/arm/mach-omap*/ board files to fill up the new audio codec
struct and include it to their twl4030_platform_data.
Than some modification to the twl4030.c codec in sound/soc/codec/
Or something along these lines...
I'll keep this in mind and try to prepare for it in the near future.
Thanks for the clarification,
