+Android Goldfish PIC

+Android Goldfish programmable interrupt device used by Android

+
+Required properties:
+
+- compatible : should contain "google,goldfish-pic"
+- reg : <registers mapping>
+- interrupts : <interrupt mapping>
+
+Example for mips when used in cascade mode:
+
+ cpuintc {
+ #interrupt-cells = <0x1>;
+ #address-cells = <0>;
+ interrupt-controller;
+ compatible = "mti,cpu-interrupt-controller";

+ #interrupt-cells = <0x1>;
+
+ interrupt-parent = <&cpuintc>;
