This is only half of the problem unfortunately :). The reason the
existence of an interrupt pin is a problem is that OpenBIOS
automatically generates an interrupt property in the device tree for the
macio device.

Please mention this in the patch description as well. Also, please make
sure to CC address@hidden on v2 :).


Thanks!
