-Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
-
-Required parameters:
--------------------
-
-compatible : Should be "st,stih407-thermal"
-
-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.
- 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:
-
- temp0@91a0000 {
- compatible = "st,stih407-thermal";
- reg = <0x91a0000 0x28>;
- clock-names = "thermal";
- clocks = <&CLK_SYSIN>;
- interrupts = <GIC_SPI 205 IRQ_TYPE_EDGE_RISING>;
- st,passive_cooling_temp = <110>;
