Required properties :

- compatible : shall contain "qcom,dispcc-sdm845".

- reg : shall contain base register location and length.

- reg-names: names of registers listed in the same order as in

	     the reg property.

- #clock-cells : shall contain 1.

- #reset-cells : shall contain 1.



Optional properties :

- vdd_<rail>-supply: The logic rail supply.



Example:

	clock_dispcc: qcom,dispcc@af00000 {

		compatible = "qcom,dispcc-sdm845";

		reg = <0xaf00000 0x100000>;

		reg-names = "cc_base";

		vdd_cx-supply = <&pm8998_s9_level>;

		#clock-cells = <1>;

		#reset-cells = <1>;
