+          value is sent for events this button generates when pressed.
+          EV_ABS/EV_REL axis will generate an event with a value of 0
+          when all buttons with linux,input-type == type and
+          linux,code == axis are released. This value is interpreted
+          as a signed 32 bit value, e.g. to make a button generate a
+          value of -1 use:

+          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).
+
