+3) Interrupt wakeup parent
+--------------------------
+
+Some interrupt controllers in a SoC, are always powered on and have a select
+interrupts routed to them, so that they can wakeup the SoC from suspend. These
+interrupt controllers do not fall into the category of a parent interrupt
+controller and can be specified by the "wakeup-parent" property and contain a
+single phandle referring to the wakeup capable interrupt controller.
+
+ Example:
+ wakeup-parent = <&pdc_intc>;
