   Shouldn't the PHYs be *under* the usb0/1 device nodes in the hierarchy?
They're not on the same bus as the MUSB controllers for sure.

   Same here.

   I don't think you need index in the name since you have the address as a 
part of the name anyway. That way it's closer to the ePAPR spec.

   The above lines are indented with spaces, the below one with tabs. Use 
tabs please.
