BMI08X Accel inertial measurement unit

Properties

Properties not inherited from the base binding file.

Name

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.

int-gpios

phandle-array

 
This property specifies the connection for INT, because the
Zephyr driver maps all interrupts to INT.  The signal defaults
to output low when produced by the sensor.

int1-map-io

int

 
Bit[0]: Map Interrupt A to INT1, Accel Data Ready
Bit[1]: Map Interrupt B to INT1
Bit[2]: Map Interrupt C to INT1

int2-map-io

int

 
Bit[0]: Map Interrupt A to INT2, Accel Data Ready
Bit[1]: Map Interrupt B to INT2
Bit[2]: Map Interrupt C to INT2

int1-conf-io

int

 
Bit[0]: reserved
Bit[1]: if set to 1, INT1 is active high, otherwise it's active low
Bit[2]: if set to 1, INT1 is open-drain, otherwise it's push-pull
Bit[3]: if set to 1, enable INT1 as an output pin
Bit[4]: if set to 1, enable INT1 as an input pin
Bit[7:5] : reserved

int2-conf-io

int

 
Bit[0]: reserved
Bit[1]: if set to 1, INT2 is active high, otherwise it's active low
Bit[2]: if set to 1, INT2 is open-drain, otherwise it's push-pull
Bit[3]: if set to 1, enable INT2 as an output pin
Bit[4]: if set to 1, enable INT2 as an input pin
Bit[7:5] : reserved

accel-hz

string

 
Default frequency of accelerometer. (Unit - Hz)

This property is required.

Legal values: '12.5', '25', '50', '100', '200', '400', '800', '1600'

accel-fs

int

 
Default full scale of accelerometer. (Unit - g)

This property is required.

Legal values: 2, 3, 4, 6, 8, 12, 16, 24

data-sync

phandle

 
Enables data sync if defined. This is to point to the bmi08x-gyro definition
that is within the same IC as the bmi08x-accel.

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).
