st,lis2ds12 (on i2c bus)

Vendor: STMicroelectronics

Note

An implementation of a driver matching this compatible is available in drivers/sensor/st/lis2ds12/lis2ds12.c.

Description

STMicroelectronics LIS2DS12 3-axis accelerometer

Properties

Properties not inherited from the base binding file.

Name

Type

Details

supply-gpios

phandle-array

 
GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

 
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

irq-gpios

phandle-array

 
DRDY pin

This pin defaults to active high when produced by the sensor.
The property value should ensure the flags properly describe
the signal that is presented to the driver.

range

int

 
Range in g. Default is power-up configuration.

- 16 # 16g (0.488 mg/LSB)
- 8  #  8g (0.244 mg/LSB)
- 4  #  4g (0.122 mg/LSB)
- 2  #  2g (0.061 mg/LSB)

Default value: 2

Legal values: 16, 8, 4, 2

power-mode

int

 
Specify the sensor power mode. Default is power-down mode

- 0 # LIS2DS12_DT_POWER_DOWN
- 1 # LIS2DS12_DT_LOW_POWER
- 2 # LIS2DS12_DT_HIGH_RESOLUTION
- 3 # LIS2DS12_DT_HIGH_FREQUENCY

Legal values: 0, 1, 2, 3

odr

int

 
Specify the default output data rate expressed in samples per second (Hz).
Default is power-down mode

- 0  # LIS2DS12_DT_ODR_OFF
- 1  # LIS2DS12_DT_ODR_1Hz_LP
- 2  # LIS2DS12_DT_ODR_12Hz5
- 3  # LIS2DS12_DT_ODR_25Hz
- 4  # LIS2DS12_DT_ODR_50Hz
- 5  # LIS2DS12_DT_ODR_100Hz
- 6  # LIS2DS12_DT_ODR_200Hz
- 7  # LIS2DS12_DT_ODR_400Hz
- 8  # LIS2DS12_DT_ODR_800Hz
- 9  # LIS2DS12_DT_ODR_1600Hz
- 10 # LIS2DS12_DT_ODR_3200Hz_HF
- 11 # LIS2DS12_DT_ODR_6400Hz_HF

Legal values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

friendly-name

string

 
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).
