- reg : Address range of the thermal registers.
The 1st reg will be recognized as common register
if it has "interrupts".

+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>;
+ };
