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>;
};
