+Loongson ls1x Interrupt Controller
+
+Required properties:
+
+- compatible : should be "loongson,ls1x-intc". Valid strings are:
+
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 2.
+- interrupts : Specifies the CPU interrupt the controller is connected to.
+
+Example:
+
+intc: interrupt-controller@1fd01040 {
+ compatible = "loongson,ls1x-intc";
+ reg = <0x1fd01040 0x18>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+
+ interrupt-parent = <&cpu_intc>;
+ interrupts = <2>;
+};
