Defines the poll period in msecs between between matrix scans, set to 0
to never exit poll mode. Defaults to 5ms if unspecified.
Default value: |
|
|
Defines the poll period in msecs between matrix scans when the matrix is
stable, defaults to poll-period-ms value if unspecified.
|
|
|
How long to wait before going from polling back to idle state. Defaults
to 100ms if unspecified.
Default value: |
|
|

|
|
|
Ignore the ghost key checking in the driver if the diodes are used
in the matrix hardware.
|

|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|

|
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.
