+MediaTek DVFSRC
+
+The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
+HW module which is used to collect all the requests from both software and
+hardware and turn into the decision of minimum operating voltage and minimum
+DRAM frequency to fulfill those requests.
+
+Required Properties:
+- compatible: Should be one of the following
+ - "mediatek,mt8183-dvfsrc": For MT8183 SoC
+- reg: Address range of the DVFSRC unit
+- clock-names: Must include the following entries:
+ "dvfsrc": DVFSRC module clock
+- clocks: Must contain an entry for each entry in clock-names.
+
+Example:
+
+ dvfsrc@10012000 {
+ compatible = "mediatek,mt8183-dvfsrc";
+ reg = <0 0x10012000 0 0x1000>;
+ clocks = <&infracfg CLK_INFRA_DVFSRC>;
+ clock-names = "dvfsrc";
+ };
