st,lsm6dso32 (on spi bus)

Vendor: STMicroelectronics

Description

STMicroelectronics LSM6DSO32 6-axis IMU (Inertial Measurement Unit) sensor
accessed through SPI bus

Properties

Properties not inherited from the base binding file.

Name

Type

Details

spi-max-frequency

int

Maximum clock frequency of device's SPI interface in Hz

This property is required.

duplex

int

Duplex mode, full or half. By default it's always full duplex thus 0
as this is, by far, the most common mode.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0    SPI_FULL_DUPLEX
  2048 SPI_HALF_DUPLEX

Legal values: 0, 2048

frame-format

int

Motorola or TI frame format. By default it's always Motorola's,
thus 0 as this is, by far, the most common format.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0     SPI_FRAME_FORMAT_MOTOROLA
  32768 SPI_FRAME_FORMAT_TI

Legal values: 0, 32768

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.

int-pin

int

Select DRDY pin number (1 or 2).

This number represents which of the two interrupt pins
(INT1 or INT2) the drdy line is attached to. This property is not
mandatory and if not present it defaults to 1 which is the
configuration at power-up.

Default value: 1

Legal values: 1, 2

accel-pm

int

Specify the accelerometer power mode.
Default is power-up configuration.

Legal values: 0, 1, 2

accel-range

int

Range in g. Default is power-up configuration.

Legal values: 0, 1, 2, 3

accel-odr

int

Specify the default accelerometer output data rate expressed in samples per second (Hz).
Default is power-up configuration.

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

gyro-pm

int

Specify the gyrometer power mode.
Default is power-up configuration.

Legal values: 0, 1

gyro-range

int

Range in dps. Default is power-up configuration.

Legal values: 0, 1, 2, 4, 6

gyro-odr

int

Specify the default gyro output data rate expressed in samples per second (Hz).
Default is power-up configuration.

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

drdy-pulsed

boolean

Selects the pulsed mode for data-ready interrupt when enabled,
and the latched mode when disabled.

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).
