1Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
2
3Required parameters:
4-------------------
5
6compatible : st,<SoC>-<module>-thermal; should be one of:
7 "st,stih415-sas-thermal",
8 "st,stih415-mpe-thermal",
9 "st,stih416-sas-thermal"
10 "st,stih416-mpe-thermal"
11 "st,stid127-thermal" or
12 "st,stih407-thermal"
13 according to the SoC type (stih415, stih416, stid127, stih407)
14 and module type (sas or mpe). On stid127 & stih407 there is only
15 one die/module, so there is no module type in the compatible
16 string.
17clock-names : Should be "thermal".
18 See: Documentation/devicetree/bindings/resource-names.txt
19clocks : Phandle of the clock used by the thermal sensor.
20 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
21
22Optional parameters:
23-------------------
24
25reg : For non-sysconf based sensors, this should be the physical base
26 address and length of the sensor's registers.
27interrupts : Standard way to define interrupt number.
28 Interrupt is mandatory to be defined when compatible is
29 "stih416-mpe-thermal".
30 NB: For thermal sensor's for which no interrupt has been
31 defined, a polling delay of 1000ms will be used to read the
32 temperature from device.

34Example:
35
36 temp1@fdfe8000 {
37 compatible = "st,stih416-mpe-thermal";
38 reg = <0xfdfe8000 0x10>;
39 clock-names = "thermal";
40 clocks = <&clk_m_mpethsens>;
41 interrupts = <GIC_SPI 23 IRQ_TYPE_NONE>;
42 };
