microchip,cap12xx (on i2c bus)

Vendor: Microchip Technology Inc.

Note

An implementation of a driver matching this compatible is available in drivers/input/input_cap12xx.c.

Description

Microchip CAP12xx family of 3, 6 and 8-channel capacitive touch sensors.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

Interrupt GPIO when not using polling mode.

repeat

boolean

Property to enable the interrupt repeat mode for prolonged touch events.

poll-interval-ms

int

Polling interval in ms when not using interrupt mode.

input-codes

array

Array of input event key codes (INPUT_KEY_* or INPUT_BTN_*).

This property is required.

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.
