Hi Mark,
I have been trying to test the AIC3x and the Voice Codec in the same kernel,
however only the AIC3x is working, I'm having problem when I try to use the
Voice Codec, I already have verified that the Voice Codec works since I tested
alone.
Please check the following output:

The following is the patch to the davinci-evm.c please check it if you see
something wrong there:
