Properties
Properties not inherited from the base binding file.

|
The INT signal default configuration is active-high. The
property value should ensure the flags properly describe the
signal that is presented to the driver.
This property is required when the trigger mode is used.
|
|
|
Default gyrscope sample rate divider. This divider is only effective
when gyro-dlpf is in range 5-184.
rate = sample_rate / (1 + gyro-sr-div)
Valid range: 0 - 255
This property is required. |
|
|
Default digital low pass filter frequency of gyroscope.
Maps to DLPF_CFG field in Configuration setting.
This property is required. Legal values: |
|
|
Default full scale of gyroscope. (Unit - DPS).
Maps to GYRO_FS_SEL field in Gyroscope Configuration setting.
This property is required. Legal values: |
|
|
Default full scale of accelerometer. (Unit - g)
Maps to ACCEL_FS_SEL field in Accelerometer Configuration setting
This property is required. Legal values: |
|
|
Default digital low pass filter frequency of accelerometer.
Maps to DLPF_CFG field in Accelerometer Configuration 2 setting.
This property is required. Legal values: |
|
|
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.
|
|
|
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.
|
Deprecated properties not inherited from the base binding file.
(None)
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 “invensense,mpu9250” compatible.

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.
