+Android Goldfish PIC
+
+Android Goldfish programmable interrupt device used by Android
+emulator.
+
+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-controller@1f000000 {
+                compatible = "google,goldfish-pic";
+                reg = <0x1f000000 0x1000>;
+
+                interrupt-controller;
+                #interrupt-cells = <0x1>;
+
+                interrupt-parent = <&cpuintc>;
+                interrupts = <0x2>;
+        };
