+* 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 at 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";
+};
