Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

Hi Rob,

I'm sorry for the mistake. I stand corrected, and will add tags on next
version.

+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";
+	};
