		Qualcomm Technologies, Inc. NPU Clock & Reset Controller Binding
		----------------------------------------------------------------

		Required properties :
		- compatible : must contain "qcom,npucc-sdm855".
		- 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_npucc: qcom,npucc {
		compatible = "qcom,npucc-sdm855";
		reg = <0x9910000 0x10000>;
		reg-names = "cc_base";
		vdd_cx-supply = <&pm855l_s6_level>;
		#clock-cells = <1>;
		#reset-cells = <1>;
		};
