1Amazon's Annapurna Labs Thermal Sensor
2
3Simple thermal device that allows temperature reading by a single MMIO
4transaction.

6Required properties:
7- compatible: "amazon,al-thermal".
8- reg: The physical base address and length of the sensor's registers.
9- #thermal-sensor-cells: Must be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
