Hi,

as mentioned before it should be using the gpiolib.h to get the right
gpios from ACPI space, right??
I am looking how this would be done in this case, hope to understand
and get it today working with gpiolib

By the way I have restest (with a lot more local debugs) and I know
now that the function arizona_dev_init()
wrongly calls the arizona_of_get_core_pdata() which could not work here...

so these two open issues I have to resolve yet before I can have fun
with the new alsa sound device

cheers
