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 Documentation/devicetree/bindings/thermal/thermal-sensor.yaml)



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>;
