CS42L52 codec

[Anna White]

Hello,

I am working with CS42L52 codec under Linux.
I have CS42L52 driver code, but I need ALSA configuration files. 
Does somebody have ALSA configuration files ?
Or recomendation how to write them ?

Thanks for responces.

P.S.

I guess you're referring to a driver, right? Don't know what an 'ALSA
configuration file' should be?

It's actually all said in this thread. You need a driver as .c and .h
file in sound/soc/codecs and modify the Makefile and Kconfig there.

Don't know how far the original poster actually got - the thread seems
to have died before any code was exposed.

If you're ending up writing the driver yourself, have a look at the
others you find in the same folder. I think the cs4270 whould be a good
thing to base your code on.
