-* 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>;
-};
-
-thermal-zones {
-	cpu_thermal: cpu-thermal {
-		polling-delay-passive = <0>;
-		polling-delay = <1000>;
-		coefficients = <(-556) 418000>;
-		thermal-sensors = <&thermal>;
-
-		trips {
-			cpu-crit {
-				temperature	= <125000>;
-				hysteresis	= <0>;
-				type		= "critical";
-			};
-		};
