- wakeup-source: Boolean, button can wake-up the system.
(Legacy property supported: "gpio-key,wakeup")
+ - wakeup-event-action: Specifies whether the key should wake the
+ system when asserted, when deasserted, or both. This property is
+ only valid for keys that wake up the system (e.g., when the
+ "wakeup-source" property is also provided).
+ Supported values are defined in linux-event-codes.h:
+ EV_ACT_ASSERTED - asserted
+ EV_ACT_DEASSERTED - deasserted
+ EV_ACT_ANY - both asserted and deasserted
- linux,can-disable: Boolean, indicates that button is connected
to dedicated (not shared) interrupt which can be disabled to
suppress events from the button.
