vishay,vcnl36825t (on i2c bus)

Vendor: Vishay Intertechnology, Inc

Description

VCNL36825T proximity and ambient light sensor.  See datasheet at
https://www.vishay.com/docs/84274/vcnl36825t.pdf

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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).

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.

operation-mode

string

 
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: auto

Legal values: 'auto', 'force'

measurement-period

int

 
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: 40

Legal values: 10, 20, 40, 80, 160, 320

proximity-it

string

 
Proximity integration time in T.
Defaults to sensor reset value.

Default value: 1

Legal values: '1', '2', '4', '8'

proximity-itb

int

 
Duration of the proximity integration time T in us.
Defaults to sensor reset value.

Default value: 25

Legal values: 25, 50

multi-pulse

int

 
Number of pulses per single measurement.
Higher values increase accuracy and power consumption.
Defaults to sensor reset value.

Default value: 1

Legal values: 1, 2, 4, 8

laser-current

int

 
Current used by the laser during measurement periods.
Defaults to minimum allowed value.

Default value: 10

Legal values: 10, 12, 14, 16, 18, 20

low-power

boolean

 
Activate low power mode.
This allows to increase the measurement period up to 320 ms.

high-gain

boolean

 
Activate the high gain mode.

sunlight-cancellation

boolean

 
Activate sunlight cancellation.

high-dynamic-output

boolean

 
Activate 16bit high dynamic output mode.
Cannot be used with threshold interrupt.
