Hi,
I am working on adding audio support to mx6qsabresd board, which
contains a wm8962 codec.
Here is the log with debug information turned on that I am getting so far:

Any idea of why register 4 and 42 read fails?

Any suggestion is appreciated.
Thanks,

Without seeing your code or knowing which kernel version you're running
it's a bit hard to comment...

This suggests that physical I/O to the device isn't working. Is it
clocked and powered?

You've not enabled any of the debug in the driver... it might give you
some hints.

Fabio,
FSL internal development team has got it work on kernel 3.5. You can
talk to Gary (Cc-ed) for details and upstreaming plan.
