* 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";
			};
		};

		cooling-maps {
		};
	};
};
