+* Mediatek Cache Coherent Interconnect(CCI) frequency device
+
+Required properties:
+- compatible: should contain "mediatek,mt8183-cci" for frequency scaling of CCI
+- clocks: for frequency scaling of CCI
+- clock-names: for frequency scaling of CCI driver to reference
+- regulator: for voltage scaling of CCI
+- operating-points-v2: for frequency scaling of CCI opp table
+
+Example:
+ cci: cci {
+ compatible = "mediatek,cci";
+ clocks = <&apmixedsys CLK_APMIXED_CCIPLL>;
+ clock-names = "cci_clock";
+ operating-points-v2 = <&cci_opp>;
+ };
+
+ &cci {
+ proc-supply = <&mt6358_vproc12_reg>;
+ };
