+* Allwinner Thermal
+
+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: Reference to the reset controller controlling the thermal controller.
+- interrupts: IRQ for the thermal controller
+- #thermal-sensor-cells : For H6 Should be 1.
+			  See ./thermal.txt for a description.
+
+Optional properties:
+- 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".
+
+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>;
+		interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
+		nvmem-cells = <&tsen_calib>;
+		nvmem-cell-names = "calib";
+		#thermal-sensor-cells = <1>;
+	};
