st,iis328dq (on i2c bus)

Vendor: STMicroelectronics

Description

STMicroelectronics IIS328DQ accelerometer accessed through I2C bus

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.

int1-gpios

phandle-array

INT_1 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.

int2-gpios

phandle-array

INT_2 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.

drdy-int-pad

int

Select DRDY pin number (1 or 2).

This number represents which of the two interrupt pins (INT_1 or INT_2), if any, the DRDY
interrupt should be generated from. If this property is not specified, no data ready
interrupts can be registered.

- 1 # drdy is generated on INT1
- 2 # drdy is generated on INT2

Legal values: 1, 2

threshold-int-pad

int

Select threshold interrupt pin number (1 or 2).

This number represents which of the two interrupt pins (INT_1 or INT_2), if any, the threshold
interrupt should be generated from. If this property is not specified, no threshold interrupts
can be registered.

- 1 # threshold interrupt is generated on INT1
- 2 # threshold interrupt is generated on INT2

Legal values: 1, 2

range

int

Range in g. Default is power-up configuration.

- 16 # 16g (1.952 mg/LSB)
- 8  #  8g (0.976 mg/LSB)
- 4  #  4g (0.488 mg/LSB)
- 2  #  2g (0.244 mg/LSB)

Default value: 2

Legal values: 16, 8, 4, 2

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).
