+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>;
+ };
