[alsa-devel] Where can I find some info about the DAI?

Hi,

I am trying to write a DAI. I am working with a wolfson wm8731 and an atmel at91sam9g20. Basically I had a look at the file eti_b1_wm8731.c, but I would like to use another ssc archi(atmel_ssc instead of at91_ssc). So I would like to know where should I find some info concerning the DAI.

Regards, Sedji
