0001 Amazon's Annapurna Labs Thermal Sensor
0002
0003 Simple thermal device that allows temperature reading by a single MMIO
0004 transaction.
0005
0006 Required properties:
0007 - compatible: "amazon,al-thermal".
0008 - reg: The physical base address and length of the sensor's registers.
0009 - #thermal-sensor-cells: Must be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.

0011 Example:
0012 thermal: thermal {
0013 compatible = "amazon,al-thermal";
0014 reg = <0x0 0x05002860 0x0 0x1>;
0015 #thermal-sensor-cells = <0x1>;
0016 };
