+Regulator cooling device.
+
+The regulator cooling device, will be used to place a voltage floor
+restriction on a rail.
+
+Properties:
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: shall be "qcom,regulator-cooling-device"
+
+- cdev-supply:
+	Usage: required
+	Value type: <phandle>
+	Definition: phandle to the regulator to which the cooling device will
+			place a floor mitigation.
+
+- regulator-levels:
+	Usage: required
+	Value type: <U32 array>
+	Definition: Array of regulator voltages the cooling device should
+			use to place a floor restriction. The voltages should
+			be specified in ascending order.
+
+- #cooling-cells: Must be 2. Please refer to
+			<devicetree/bindings/thermal/thermal.txt> for more
+			details.
+
+Example:
+
+	mv_cdev: mx-cdev-lvl {
+		compatible = "qcom,regulator-cooling-device";
+		cdev-supply = <&regulator-cdev-supply>;
+		regulator-levels = <RPMH_REGULATOR_LEVEL_OFF
+			RPMH_REGULATOR_LEVEL_NOM>;
+		#cooling-cells = <2>;
+	};
