+Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
+
+Required parameters:
+-------------------
+
+compatible : 	st,<SoC>-<module>-thermal; should be one of:
+		  "st,stih415-sas-thermal",
+		  "st,stih415-mpe-thermal",
+		  "st,stih416-sas-thermal"
+		  "st,stih416-mpe-thermal"
+		  "st,stid127-thermal" or
+		  "st,stih407-thermal"
+		according to the SoC type (stih415, stih416, stid127, stih407)
+		and module type (sas or mpe). On stid127 & stih407 there is only
+		one die/module, so there is no module type in the compatible
+		string.
+clock-names : 	Should be "thermal".
+		  See: Documentation/devicetree/bindings/resource-names.txt
+clocks : 	Phandle of the clock used by the thermal sensor.
+		  See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Optional parameters:
+-------------------
+
+reg : 		For non-sysconf based sensors, this should be the physical base
+		address and length of the sensor's registers.
+interrupts :	Standard way to define interrupt number.
+		Interrupt is mandatory to be defined when compatible is
+		"stih416-mpe-thermal".
+		  NB: For thermal sensor's for which no interrupt has been
+		  defined, a polling delay of 1000ms will be used to read the
+		  temperature from device.
+
+Example:
+
+	temp1@fdfe8000 {
+		compatible	= "st,stih416-mpe-thermal";
+		reg		= <0xfdfe8000 0x10>;
+		clock-names	= "thermal";
+		clocks		= <&clk_m_mpethsens>;
+		interrupts	= <GIC_SPI 23 IRQ_TYPE_NONE>;
+	};
