Vendor: NXP Semiconductors
Note
An implementation of a driver matching this compatible is available in drivers/sensor/nxp/fxos8700/fxos8700.c.
Description

Properties
Properties not inherited from the base binding file.

|
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.

|
RST pin
This pin defaults to active high when consumed by the sensor.
The property value should ensure the flags properly describe
the signal that is presented to the driver.
|
|
|
INT1 pin
This pin defaults to active low when produced by the sensor.
The property value should ensure the flags properly describe
the signal that is presented to the driver.
|
|
|
INT2 pin
This pin defaults to active low when produced by the sensor.
The property value should ensure the flags properly describe
the signal that is presented to the driver.

Pulse configuration register
Default value: |
|
|
Pulse X-axis threshold
Threshold to start the pulse-event detection procedure on the X-axis.
Threshold values for each axis are unsigned 7-bit numbers with a fixed
resolution of 0.063 g/LSB, corresponding to an 8g acceleration
full-scale range.
Default value: |
|
|
Pulse Y-axis threshold
Threshold to start the pulse-event detection procedure on the Y-axis.
Threshold values for each axis are unsigned 7-bit numbers with a fixed
resolution of 0.063 g/LSB, corresponding to an 8g acceleration
full-scale range.
Default value: |
|
|
Pulse Z-axis threshold
Threshold to start the pulse-event detection procedure on the Z-axis.
Threshold values for each axis are unsigned 7-bit numbers with a fixed
resolution of 0.063 g/LSB, corresponding to an 8g acceleration
full-scale range.
Default value: |
|
|
Pulse time limit
The maximum time interval that can elapse between the start of the
acceleration on the selected channel exceeding the specified threshold
and the end when the channel acceleration goes back below the specified
threshold. The resolution depends upon the sample rate (ODR) and the
high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For
ODR=800 Hz and pls_hpf_en=0, the resolution is 0.625 ms/LSB.
Default value: |
|
|
Pulse latency
The time interval that starts after the first pulse detection where the
pulse-detection function ignores the start of a new pulse. The
resolution depends upon the sample rate (ODR) and the high-pass filter
configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and
pls_hpf_en=0, the resolution is 1.25 ms/LSB.
Default value: |
|
|
Pulse window
The maximum interval of time that can elapse after the end of the
latency interval in which the start of the second pulse event must be
detected provided the device has been configured for double pulse
detection. The detected second pulse width must be shorter than the
time limit constraint specified by the PULSE_TMLT register, but the end
of the double pulse need not finish within the time specified by the
PULSE_WIND register. The resolution depends upon the sample rate (ODR)
and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]).
For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
Default value: |
|
|
Magnetic vector-magnitude configuration register
Default value: |
|
|
Magnetic vector-magnitude threshold most significant byte.
Resolution is 0.1 uT/LSB.
|
|
|
Magnetic vector-magnitude threshold least significant byte.
Resolution is 0.1 uT/LSB.
Default value: |
|
|
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 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 “nxp,fxos8700” compatible.

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

|
|
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.

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