ams,tsl2540 (on i2c bus)

Vendor: AMS AG

Description

TSL2540 series ambient light sensor.  See datasheet at
https://ams.com/documents/20143/36005/TSL2540_DS000564_4-00.pdf/39728ac4-098c-9eca-b5ca-61d9c6f3a588

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

Identifies the interrupt pin

glass-attenuation

int

Visible light attenuation.
Integer value for a representation with 5 decimal points.
This default value (1.00000) is chosen for free open space (no glass).
Example: 1.2 would be 120000

Default value: 100000

glass-ir-attenuation

int

Infa-red light attenuation.
Integer value for a representation with 5 decimal points.
This default value (1.00000) is chosen for free open space (no glass).
Example: 1.2 would be 120000

Default value: 100000

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.
