+Realtek Clock/Reset Controller
+==============================
+
+Realtek CRT/ISO controller device-tree binding for Realtek Platforms.
+
+This binding uses the common clock binding[1].
+
+The controller node should be the child of a syscon node with the required
+propertise:
+
+- compatible :
+	should contain only one of the following:
+		"realtek,rtd1619-cc" for RTD1619 CRT clock controller,
+		"realtek,rtd1619-ic" for RTD1619 ISO clock controller,
+
+- #clock-cells : should be 1.
+
+- #reset-cells : should be 1.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Example:
+
+	crt@98000000 {
+		compatible = "realtek,rtd1619-crt", "simple-mfd", "syscon";
+		reg = <0x98000000 0x1000>;
+
+		cc: cc@98000000 {
+			compatible = "realtek,rtd1619-cc";
+			#clock-cells = <1>;
+			#reset-cells = <1>;
+		};
+	};
+
+	consumer {
+		clocks = <&cc CC_CKE_GSPI>;
+	};
