+* Temperature Sensor on hisilicon SoC
+
+** Required properties :
+
+- compatible: "hisilicon,thermal-tsensor".
+- reg: physical base address of thermal sensor and length of memory mapped
+  region.
+- offset: reg offset of each sensor.
+- coefficients:	An array of integers (one signed cell) containing
+		coefficients to turn adc value to temperture.
+- hisi,adc-range: adc value range, minimum value is followed by maximum value.
+- #thermal-sensor-cells: Should be 1. See ./thermal.txt for a description.
+
+Example :
+
+tsensor: tsensor@FFF3000 {
+	compatible = "hisilicon,tsensor";
+	reg = <0x0 0xfff30000 0x0 0x1000>;
+	offset = <0x1c 0x5c 0x9c>;
+	coefficients = <165000 (-40000)>;
+	hisi,adc-range = <0x74 0x39A>;
+	#thermal-sensor-cells = <1>;
+};
