+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 ./thermal.txt 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";
+ };
+ };
