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";
|
};
|
};
|
|
};
|
};
