To what tree should this patch go? My wireless-drivers-next tree doesn't
even have this file.

v1 -> v2: Replace interrupts and interrupt-parent with interrupts-extended.
v2 -> v3: Move the pinctrl-0 = <_pins> to the wlcore node.
v3 -> v4: replace interrupts-extended with interrupts and interrupt-parent. 
(revert v2 modification).
   According to Rob Herring and 
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt,
  interrupts-extended should only be used when a device has multiple 
interrupt parents.

v1 -> v2: Replace interrupts and interrupt-parent with interrupts-extended.
v2 -> v3: Move the pinctrl-0 = <_pins> to the wlcore node.
v3 -> v4: replace interrupts-extended with interrupts and interrupt-parent. 
(revert v2 modification).
  According to Rob Herring and 
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt,
  interrupts-extended should only be used when a device has multiple 
interrupt parents.
