st,stm32-temp-cal
Vendor: STMicroelectronics N.V.
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 for production calibrated sensors with two calibration temperatures.
Properties
Node specific properties
Properties not inherited from the base binding file.

|
|
Address of TS_CAL2 calibration parameter
This property is required. |
|
|
Temperature at which TS_CAL2 has been measured (TS_CAL2_TEMP)
This property is required. |
|
|
Address of TS_CAL1 calibration parameter
This property is required. |
|
|
Temperature at which TS_CAL1 has been measured (TS_CAL2_TEMP)
This property is required. |
|
|
Analog voltage reference (Vref+) voltage with which
temperature sensor calibration parameters have been
measured
This property is required. |
|
|
ADC resolution used for measuring calibration data
This is usually equal to the ADC's native resolution.
Most series have a 12-bit ADC, but 14-bit and 16-bit
also exists on e.g., STM32U5 and STM32H7 (16) series.
Default value: Legal values: |
|
|
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 node specific properties
Deprecated properties not inherited from the base binding file.
(None)
Base properties
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-cal” 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.
