AIC32x4 Codec on AM335x

Dear Support,

   I am trying to port the AIC32x4 driver on the AM335x SoC. The driver is already available and I followed the TI Wiki to port the codec driver.

I would ask what are exactly the steps to have the audio card registered, since the  "ALSA device list" is always "no soundcard found".

During the boot the audio codec is registered and the mcasp too.


Oddly, in the snd_soc_card, I had to increase the .num_links since with a value of 1 the boot crashed in thesoc-core.c in the snd_soc_register_dais function, here:

list_add(&dai->list, &dai_list);

Below the dmesg I had, I put some extra printk to debug.

Thank you in advance.
