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