Amazon's Annapurna Labs Thermal Sensor
Simple thermal device that allows temperature reading by a single MMIO
transaction.
Required properties:
- compatible: "amazon,al-thermal".
- reg: The physical base address and length of the sensor's registers.
- #thermal-sensor-cells: Must be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
Example:
thermal: thermal {
compatible = "amazon,al-thermal";
reg = <0x0 0x05002860 0x0 0x1>;
#thermal-sensor-cells = <0x1>;
};
thermal-zones {
thermal-z0 {
polling-delay-passive = <250>;
polling-delay = <1000>;
thermal-sensors = <&thermal 0>;
trips {
critical {
temperature = <105000>;
hysteresis = <2000>;
type = "critical";
};
};
};
};
