|
|
GPIO connected to the motion pin, active low.
This property is required. |
|
|
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.
|
|
|
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.
|
|
|
CPI resolution for the X axis, range 0 to 1275, rounded down to the
closest supported value in increments of 5.
|
|
|
CPI resolution for the Y axis, range 0 to 1275, rounded down to the
closest supported value in increments of 5.
|
|
|
Invert X axis values.
|
|
|
Invert Y axis values.
|
|
|
Enable sleep1 mode.
|
|
|
Enable sleep2 mode, only valid if sleep1 is also enabled.
|
|
|
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.
|
|
|
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.
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “pixart,pat912x” compatible.

|
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
