Acquire a wake lock in the Sensors 2.0 Default implementation whenever there are outstanding WAKE_UP events. Release the wake lock whenever the number of oustanding WAKE_UP events is zero or at least SensorTimeout::WAKE_LOCK_SECONDS seconds have elapsed since the previous WAKE_UP event was written to the Event FMQ. Bug: 111070257 Test: Builds, wake lock is acquired and released as expected. Change-Id: I7c57724430144fd4022646d1fef1b1fa8bc4235d
