+Realtek RTD129x IRQ Interrupt Controller
+=======================================
+
+Required properties:
+
+- compatible           :  Should be one of the following:
+                          - "realtek,rtd129x-intc-misc"
+                          - "realtek,rtd129x-intc-iso"
+- reg                  :  Specifies the address of the ISR, IER and Unmask
+                          register in couples of "address length".
+- interrupts           :  Specifies the interrupt line which is mux'ed.
+- interrupt-controller :  Presence indicates the node as interrupt controller.
+- #interrupt-cells     :  Shall be 1. See common bindings in interrupt.txt.
+
+
+Example:
+
+	interrupt-controller@98007000 {
+		compatible = "realtek,rtd129x-iso-irq-mux";
+		reg = <0x98007000 0x4 0x98007040 0x4 0x98007004 0x4>;
+		interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-controller;
+		#interrupt-cells = <1>;
+	};
