1 Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
2
3 Required parameters:
4 -------------------
5
6 compatible :    Should be "st,stih407-thermal"
7
8 clock-names :   Should be "thermal".
9                   See: Documentation/devicetree/bindings/resource-names.txt
10 clocks :        Phandle of the clock used by the thermal sensor.
11                   See: Documentation/devicetree/bindings/clock/clock-bindings.txt
12
13 Optional parameters:
14 -------------------
15
16 reg :           For non-sysconf based sensors, this should be the physical base
17                 address and length of the sensor's registers.
18 interrupts :    Standard way to define interrupt number.
19                   NB: For thermal sensor's for which no interrupt has been
20                   defined, a polling delay of 1000ms will be used to read the
21                   temperature from device.

25         temp0@91a0000 {
26                 compatible = "st,stih407-thermal";
27                 reg = <0x91a0000 0x28>;
28                 clock-names = "thermal";
29                 clocks = <&CLK_SYSIN>;
30                 interrupts = <GIC_SPI 205 IRQ_TYPE_EDGE_RISING>;
31                 st,passive_cooling_temp = <110>;
