Hmm... the version of the AOA driver in -current changed the way the
mixer is detected: it now attaches a real I2C device driver to the
mixer device node.

It seems that in this case the device node properties are different to
what the driver knows, so it fails to match.

Could you send the output of the 'i2c' OF device tree? Something like
the following, from FreeBSD -current:

% ofwdump -pr mac-io/i2c

Thanks
