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 {
|
|
