+Richtek RT1711H TypeC PD Controller.
+
+Required properties:
+ - compatible : Must be "richtek,rt1711h".
+ - reg : Must be 0x4e, it's slave address of RT1711H.
+
+Recommended properties :
+ - interrupt-parent : the phandle for the interrupt controller that
+   provides interrupts for this device.
+ - interrupts : <a b> where a is the interrupt number and b represents an
+   encoding of the sense and level information for the interrupt.
+
+Optional properties :
+ - rt,intr-gpios : IRQ GPIO pin that's connected to RT1711H interrupt.
+   if interrupt-parent & interrupts are not defined, use this property instead.
+
+Example :
+rt1711h@4e {
+	compatible = "richtek,rt1711h";
+	reg = <0x4e>;
+	interrupt-parent = <&gpio26>;
+	interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
+};
+
+Example using rt,intr-gpios :
+rt1711h@4e {
+	compatible = "richtek,rt1711h";
+	reg = <0x4e>;
+	rt,intr-gpios = <&gpio26 0 0x0>;
+};
