st,stm32-temp
Vendor: STMicroelectronics
Note
An implementation of a driver matching this compatible is available in drivers/sensor/st/stm32_temp/stm32_temp.c.
Description
STM32 family TEMP node
Properties
Properties not inherited from the base binding file.

|---|---|---|
|
|
Voltage of temperature sensor at 25°C (in mV), found in MCU datasheet
chapters "Electrical characteristics" or "Operating conditions"
This property is required. |
|
|
Average slope of T-V chart (in mV/°C), found in MCU datasheet
chapters "Electrical characteristics" or "Operating conditions"
This property is required. |
|
|
Negative Temperature Coefficient
Set when the sensor's value is inversely proportional to temperature
(i.e., the sensor's value decreases as the temperature increases).
This is visible in the formula used for temperature calculation, which has the
form "Calibration_Value - ADC_Value" rather than "ADC_Value - Calibration_Value".
|
|
|
Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.
This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32-temp” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
