I'm re-sending this set, as one of the maintainers' email addresses
is incorrect in the MAINTAINERS file.
This patchset adds full support for 2 types of Thermal Controllers
produced by STMicroelectronics. One is a more traditional memory
mapped variant, the other is controlled solely by system configuration
registers.

+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>;
+ };

1.8.3.2
This is the traditional way of obtaining a device driver's register
address space. The aim of this driver is to supply controller specific
information to the ST Thermal Core.

We supply two of these. The first is controlled by the System Configuration
registers and the second one provided is a more traditional 'memory mapped'
variant. Each are handled by they own sub-driver.
