+Qualcomm Technologies, Inc. Display Clock Controller Binding
+------------------------------------------------------------
+
+Required properties :
+
+- compatible : shall contain "qcom,sdm845-dispcc"
+- reg : shall contain base register location and length.
+- #clock-cells : from common clock binding, shall contain 1.
+- #reset-cells : from common reset binding, shall contain 1.
+- #power-domain-cells : from generic power domain binding, shall contain 1.
+
+Example:
+	dispcc: clock-controller@...0000 {
+		compatible = "qcom,sdm845-dispcc";
+		reg = <0xaf00000 0x100000>;
+		#clock-cells = <1>;
+		#reset-cells = <1>;
+		#power-domain-cells = <1>;
+	};
