12*a241f1a1SRob Herring (Arm)description:
13*a241f1a1SRob Herring (Arm)  This binding specifies what properties must be available in the device tree
14*a241f1a1SRob Herring (Arm)  representation of an Open PIC compliant interrupt controller.  This binding is
15*a241f1a1SRob Herring (Arm)  based on the binding defined for Open PIC in [1] and is a superset of that
16*a241f1a1SRob Herring (Arm)  binding.
