I'm trying to add support for the tlv320aic3104a present on a
custom board using an am335x.

I see that Benoit seemed to have been successful when using the
tlv320aic3x driver with minor modifications.

On the other hand, in the past, I've used a tlv320aic3100 with the
tlv320aic31xx driver.

My plan for now is to use the tlv320aic3x driver with snd-soc-evm as
this is the one it is using (it is using .codec_dai_name =

I had no luck until now but I still have to review my pinmuxing. But
before I investigate to much, can you confirm what codecs are supported
by which driver? I'm pretty sure that would be a nice addition to the
documentation too.
