vishay,vcnl4040 (on i2c bus)

Vendor: Vishay Intertechnology, Inc

Note

An implementation of a driver matching this compatible is available in drivers/sensor/vishay/vcnl4040/vcnl4040.c.

Description

VCNL4040 proximity and ambient light sensor.  See datasheet at
https://www.vishay.com/docs/84274/vcnl4040.pdf

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

 
The INT pin signals that a programmable interrupt function
for ALS and PS with upper and lower thresholds has been
triggered. The sensor generates an active-low level signal
which remains asserted until the data is read.

led-current

int

 
LED current in mA

Default value: 50

Legal values: 50, 75, 100, 120, 140, 160, 180, 200

led-duty-cycle

int

 
LED duty cycle in Hz

Default value: 40

Legal values: 40, 80, 160, 320

proximity-it

string

 
Proximity integration time in T

Default value: 1

Legal values: '1', '1.5', '2', '2.5', '3', '3.5', '4', '8'

proximity-trigger

string

 
Proximity trigger type

Default value: disabled

Legal values: 'disabled', 'close', 'away', 'close-away'

als-it

int

 
ALS integration time in ms

Default value: 80

Legal values: 80, 160, 320, 640

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.
