     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>;
    };
