|
Mode of operation.
- "auto": the sensor performs sampling continuously,
- "force": the sampling is performed on every fetch command.
Defaults to sensor reset value.
Note: "force"-mode only available if low-power mode inactive.
Default value: Legal values: |
|
|
Measurement period of the sensors in ms.
Higher values yield lower power consumption.
Note:
- [10, 80] ms only if low power mode is inactive
- [80, 320] ms only in low power mode
Defaults to 40 ms which is supported in both normal and low-power mode.
Default value: Legal values: |
|
|
Proximity integration time in T.
Defaults to sensor reset value.
Default value: Legal values: |
|
|
Duration of the proximity integration time T in us.
Defaults to sensor reset value.
Default value: Legal values: |
|
|
Number of pulses per single measurement.
Higher values increase accuracy and power consumption.
Defaults to sensor reset value.
Default value: Legal values: |
|
|
Current used by the laser during measurement periods.
Defaults to minimum allowed value.
Default value: Legal values: |
|
|
Activate low power mode.
This allows to increase the measurement period up to 320 ms.
|
|
|
Activate the high gain mode.
|
|
|
Activate sunlight cancellation.
|
|
|
Activate 16bit high dynamic output mode.
Cannot be used with threshold interrupt.
|
|
|
The INT signal connection.
The signal is active-low as produced by the sensor.
|
|
|
Specifies the interrupt behavior.
- "normal": signal if exceeds high or falls below lower threshold
and proximity count is reached.
- "first high": signal if exceeds high threshold first time and signal again
if falls below lower threshold, and proximity count is reached.
Do not trigger if high threshold was never exceeded.
- "logic high / low": signal if high threshold is exceeded and proximity counts is reached,
deactivate if falls below lower threshold.
Defaults to "normal" as this is the easiest configurable mode.
Default value: Legal values: |
|
|
Number of consecutive measurements above/below threshold to signal an interrupt.
Defaults to sensor reset value
Default value: Legal values: |
|
|
Activates "smart persistence" feature, aimed to reduce total reaction time
until an interrupt is issued.
|
|
|
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).
|
|
|
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 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 “vishay,vcnl36825t” 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.
