+* Broadcom Northstar Thermal
+
+This binding describes thermal sensor that is part of Northstar's DMU (Device
+Management Unit).
+
+Required properties:
+- compatible : Must be "brcm,ns-thermal"
+- reg : iomem address range of PVTMON registers
+- #thermal-sensor-cells : Should be <0>
+
+Example:
+
+thermal: thermal@1800c2c0 {
+       compatible = "brcm,ns-thermal";
+       reg = <0x1800c2c0 0x10>;
+       #thermal-sensor-cells = <0>;
+};
