Hi,

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.
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-January/058966.html

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 =
"tlv320aic3x-hifi").

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.

Hi Alexandre,
Based on a brief look at the data sheet I am afraid you will not have any luck using tlv320aic3x driver with tlv320aic3104. tlv320aic31xx is a better match, but sill not close enough.

Based on the register map you may have a change to get the codec working using tlv320aic32x4 driver. At least the register map appears to be a pretty good match. However, I have no experience either with the driver or the codec.

Best regards,
Jyri
