   1 Cirrus Logic CLPS711X Interrupt Controller
   2
   3 Required properties:
   4
   5 - compatible: Should be "cirrus,ep7209-intc".
   6 - reg: Specifies base physical address of the registers set.
   7 - interrupt-controller: Identifies the node as an interrupt controller.
   8 - #interrupt-cells: Specifies the number of cells needed to encode an
   9   interrupt source. The value shall be 1.

  37                 compatible = "cirrus,ep7312-intc", "cirrus,ep7209-intc";
  38                 reg = <0x80000000 0x4000>;
  39                 interrupt-controller;
  40                 #interrupt-cells = <1>;
  41         };
