Description

BMI08X Accel inertial measurement unit

Properties

Node specific 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.

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).

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 “bosch,bmi08x-accel” compatible.

Name

Type

Details

reg

array

 
device address on i2c bus

This property is required.

See Important properties for more information.

status

string

 
indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

 
compatible strings

This property is required.

See Important properties for more information.

reg-names

string-array

 
name of each register space

interrupts

array

 
interrupts for device

See Important properties for more information.

interrupts-extended

compound

 
extended interrupt specifier for device

interrupt-names

string-array

 
name of each interrupt

interrupt-parent

phandle

 
phandle to interrupt controller node

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

This property is deprecated.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

io-channels

phandle-array

 
IO channels specifiers

io-channel-names

int

 
Number of cells in power-domains property

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

wakeup-source

boolean

 
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.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.
