+* Thermal Sensor Controller on Allwinner SoCs
+
+Required properties:
+- compatible : should be "allwinner,<name>-ths"
+   "allwinner,sun8i-h3-ths": found on H3 and H2+ SoCs
+   "allwinner,sun50i-h5-ths": found on H5 SoC
+   "allwinner,sun50i-a64-ths": found on H5 SoC
+- reg : physical base address of the controller and length of memory mapped
+	region.
+- interrupts : The interrupt number to the cpu. The interrupt specifier format
+	       depends on the interrupt controller.
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Shall be "apb" for the bus, and "ths" for
+		the peripheral clock.
+- resets : Must contain an entry for each entry in reset-names.
+	   See ../reset/reset.txt for details.
+- reset-names : Must be "apb".
+- #thermal-sensor-cells : Depend on the SoC
+   For H3 should be 0
+   For H5 should be 1
+   For A64 should be 2
+   See ./thermal.txt for a description.
+- nvmem-cells : Phandle to the calibration data
+- nvmem-cell-names = Should be "ths-calib"
+
+Example:
+
+ths: thermal_sensor@1c25000 {
+	compatible = "allwinner,sun8i-h3-ths";
+	reg = <0x01c25000 0x100>;
+	interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+	clocks = <&ccu CLK_BUS_THS>, <&ccu CLK_THS>;
+	clock-names = "apb", "ths";
+	resets = <&ccu RST_BUS_THS>;
+	reset-names = "apb";
+	#thermal-sensor-cells = <0>;
+	status = "disabled";
+
+	nvmem-cells = <&ths_calib>;
+	nvmem-cell-names = "ths-calib";
+};
