It doesn't make any difference to me which one we pick. I'm just
listing all of the possible combinations. I just want to pick a model
so that we can write the code.

I see your point about putting the child node onto the control bus.
ac97 is both a control and data bus. For the i2s case the child should
go onto the i2c bus.
