+Qualcomm Graphics Clock & Reset Controller Binding
+--------------------------------------------------
+
+Required properties :
+- compatible : shall contain "qcom,sdm845-gpucc".
+- 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:
+ gpucc: clock-controller@5090000 {
+ compatible = "qcom,sdm845-gpucc";
+ reg = <0x5090000 0x9000>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ #power-domain-cells = <1>;
+ };
