-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@...01040 {
-	compatible = "loongson,ls1x-intc";
-	reg = <0x1fd01040 0x18>;
-
-	interrupt-controller;
-	#interrupt-cells = <2>;
-
-	interrupt-parent = <&cpu_intc>;
-	interrupts = <2>;
