19 The "interrupt-parent" property is used to specify the controller to which
22 interrupt client node or in any of its parent nodes. Interrupts listed in the
23 "interrupts" property are always in reference to the node's interrupt parent.
25 The "interrupts-extended" property is a special form; useful when a node needs
26 to reference multiple interrupt parents or a different interrupt parent than
