+ - Andrew-sh.Cheng <andrew-sh.cheng@mediatek.com>
+
+description: |
+ This module is used to create CCI DEVFREQ.
+ The performance will depend on both CCI frequency and CPU frequency.
+ For MT8183, CCI co-buck with Little core.
+ Contain CCI opp table for voltage and frequency scaling.
+
+properties:
+ compatible:
+ const: "mediatek,mt8183-cci"
+
+ clocks:
+ maxItems: 1
+
+ clock-names:
+ const: "cci"
+
+ operating-points-v2: true
+ opp-table: true
+
+ proc-supply:
+ description:
+ Phandle of the regulator that provides the supply voltage.
+
+required:
+ - compatible
+ - clocks
+ - clock-names
+ - proc-supply
+
+examples:

+ #include <dt-bindings/clock/mt8183-clk.h>
+ cci: cci {
+ compatible = "mediatek,mt8183-cci";
+ clocks = <&apmixedsys CLK_APMIXED_CCIPLL>;
+ clock-names = "cci";
