+Binding for Thermal Sensor of Allwinner SOC.
+
+This describes the device tree binding for the Allwinner thermal controller
+which measures the on-SoC temperatures.
+
+Required properties:
+- compatible:
+ - "allwinner,sun50i-h6-ths" : For H6
+- reg: Address range of the thermal controller
+- clocks, clock-names: Clocks needed for the thermal controller.
+ The required clocks for h6 are: "bus".
+- resets, reset-names: Reference to the reset controller controlling
+ the thermal controller.
+- nvmem-cells: A phandle to the calibration data provided by a nvmem device. If
+ unspecified default values shall be used.
+- nvmem-cell-names: Should be "calib"
+- #thermal-sensor-cells : For H6 Should be 1.
+ See ./thermal.txt for a description.
+
+Example:
+
+ ths: ths@1c25000 {
+ compatible = "allwinner,sun50i-h6-ths";
+ reg = <0x05070400 0x100>;
+ clocks = <&ccu CLK_BUS_THS>;
+ clock-names = "bus";
+ resets = <&ccu RST_BUS_THS>;
+ reset-names = "bus";
+ nvmem-cells = <&tsen_calib>;
+ nvmem-cell-names = "calib";
+ #thermal-sensor-cells = <1>;
+ };
