+* 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";
+ };
