85 wakeup-event-action:
87 Specifies whether the key should wake the system when asserted, when
88 deasserted, or both. This property is only valid for keys that wake up the
89 system (e.g., when the "wakeup-source" property is also provided).
91 Supported values are defined in linux-event-codes.h:
93 EV_ACT_ANY - both asserted and deasserted
94 EV_ACT_ASSERTED - asserted
95 EV_ACT_DEASSERTED - deasserted
