+* Generic power domain based thermal warming device.
+
+This binding describes the power domains that can be used as a
+thermal warming device.
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be "thermal-power-domain-wdev"
+
+- #temp-reg-cells:
+	Usage: required
+	Value type: <u32>
+	Definition: Must be 2
+
+- power-domains:
+	Usage: required
+	Value type: <phandle>
+	Definition: reference to power-domains that match power-domain-names
+
+- power-domain-names:
+	Usage: required
+	Value type: <stringlist>
+	Definition: The power-domains that can behave as warming devices
+
+Example 1
+thermal_wdev: rpmhpd_mx_wdev {
+		compatible = "thermal-power-domain-wdev";
+		#cooling-cells = <2>;
+		power-domains =  <&rpmhpd SDM845_MX>;
+		power-domain-names = "mx";
