pixart,pat912x (on i2c bus)

Vendor: PixArt Imaging Inc.

Description

PAT9125EL Miniature Optical Navigation Chip

Properties

Properties not inherited from the base binding file.

Name

Type

Details

motion-gpios

phandle-array

GPIO connected to the motion pin, active low.

This property is required.

zephyr,axis-x

int

The input code for the X axis to report for the device, typically any of
INPUT_REL_*. No report produced for the device X axis if unspecified.

zephyr,axis-y

int

The input code for the Y axis to report for the device, typically any of
INPUT_REL_*. No report produced for the device Y axis if unspecified.

res-x-cpi

int

CPI resolution for the X axis, range 0 to 1275, rounded down to the
closest supported value in increments of 5.

res-y-cpi

int

CPI resolution for the Y axis, range 0 to 1275, rounded down to the
closest supported value in increments of 5.

invert-x

boolean

Invert X axis values.

invert-y

boolean

Invert Y axis values.

sleep1-enable

boolean

Enable sleep1 mode.

sleep2-enable

boolean

Enable sleep2 mode, only valid if sleep1 is also enabled.

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.
