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. Add wakeup-parent DT property to refer to these interrupt
controllers.

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>;
