There's about half a dozen versions of those :-) I assume the older
PowerMac7,2 ? It's the one that tends to have missing bits in the
device-tree. In that case, I think we still have one of these working at
work, I can have a look when I'm back.

But where is the deq node ? Under i2c or under sound ? If not under i2c
then we need to do something else entirely.

For modalias I'm thinking best might be to have the platform code create
a platform device for sound and have aoa core match on that ;-)
