Binding for Thermal Sensor driver for BCM2835 SoCs.

Required parameters:
-------------------

compatible: 		should be one of: "brcm,bcm2835-thermal",
			"brcm,bcm2836-thermal" or "brcm,bcm2837-thermal"
reg:			Address range of the thermal registers.
clocks: 		Phandle of the clock used by the thermal sensor.
#thermal-sensor-cells:	should be 0 (see thermal.txt)

Example:

thermal-zones {
	cpu_thermal: cpu-thermal {
		polling-delay-passive = <0>;
		polling-delay = <1000>;

		thermal-sensors = <&thermal>;

		trips {
			cpu-crit {
				temperature	= <80000>;
				hysteresis	= <0>;
				type		= "critical";
			};
		};

		coefficients = <(-538)	407000>;

		cooling-maps {
		};
	};
};

thermal: thermal@7e212000 {
	compatible = "brcm,bcm2835-thermal";
	reg = <0x7e212000 0x8>;
	clocks = <&clocks BCM2835_CLOCK_TSENS>;
	#thermal-sensor-cells = <0>;
};
