That would explain why I see an "irq but nobody cared" message when
booting the original system.

This isn't the problem I meant though. When adding interrupt-parent =
<&pcawan>; interrupts = <7 IRQ_TYPE_LEVEL_LOW>; to the phy node I get an
error saying that there is no irq domain associated with this device.

CZ11NIC12 is indicated on my board.
