[PATCH v3 1/2] dt-bindings: interrupt-controller: Add binding for the Microsemi Ocelot interrupt controller

[Alexandre Belloni <alexandre.belloni@bootlin.com>]

Add the Device Tree binding documentation for the Microsemi Ocelot
interrupt controller that is part of the ICPU. It is connected directly to
the MIPS core interrupt controller.

+Microsemi Ocelot SoC ICPU Interrupt Controller
+
+Required properties:
+
+- compatible : should be "mscc,ocelot-icpu-intr"
+- 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 1.
+- interrupt-parent : phandle of the CPU interrupt controller.
+- interrupts : Specifies the CPU interrupt the controller is connected to.
+
+Example:
+
+		intc: interrupt-controller@70000070 {
+			compatible = "mscc,ocelot-icpu-intr";
+			reg = <0x70000070 0x70>;
+			#interrupt-cells = <1>;
+			interrupt-controller;
+			interrupt-parent = <&cpuintc>;
+			interrupts = <2>;
+		};
