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>;
};
