[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

Have you looked in Documentation/sound/alsa/soc ?

Yes, but I can't find anything regarding the cpu_dai. There some documentation about the codeac DAI, but nothing about the cpu one. I was wondering if there is any update concerning this documentation?

It's the same thing (struct) now. Documentation probably needs updated to reflect this.
If you are starting a DAI driver from scratch then it's best to look at the other CPU dai drivers as examples.

There is some documentation in Documentation/sound/alsa/soc which may be helpful. It should also be useful to refer to existing drivers for examples of how to do things - the PXA and S3C24xx architectures get much of the attention here so are among the best places to look.
If you run into trouble please just ask here.
