If userspace requests current KEY-state, they very likely assume that no such events are pending in the output queue of the evdev device. Otherwise, they will parse events which they already handled via EVIOCGKEY(). For XKB applications this can cause irreversible keyboard states if a modifier is locked multiple times because a CTRL-DOWN event is handled once via EVIOCGKEY() and once from the queue via read(), even though it should handle it only once. Therefore, lets do the only logical thing and flush the evdev queue atomically during this ioctl. We only flush events that are affected by the given ioctl. This only affects boolean events like KEY, SND, SW and LED. ABS, REL and others are not affected as duplicate events can be handled gracefully by user-space. Note: This actually breaks semantics of the evdev ABI. However, investigations showed that userspace already expects the new semantics and we end up fixing at least all XKB applications. All applications that are aware of this race-condition mirror the KEY state for each open-file and detect/drop duplicate events. Hence, they do not care whether duplicates are posted or not and work fine with this fix. Also note that we need proper locking to guarantee atomicity and avoid dead-locks. event_lock must be locked before queue_lock (see input-core). However, we can safely release event_lock while flushing the queue. This allows the input-core to proceed with pending events and only stop if it needs our queue_lock to post new events. This should guarantee that we don't block event-dispatching for too long while flushing a single event queue.

Attempt to reboot the system gracefully when a key combo is detected. If the reste combination is pressed the 2nd time we assume that graceful reboot failed and perform emergency reboot. This fucntionality is useful when UI is stuck but the system is otherwise working fine.

If pdata is NULL, atmel_tsadcc_probe() will release all the resources and return 0, but we need a error code is returned in this case. Fix to return -EINVAL and move the check for pdata to the begin of this function.

There is an embedded PWRC(power controller) in SiRFprimaII and SiRFatlasVI, we have an ONKEY button which can generate interrupt to IRQ controller. In a typical user scenarios, at the runtime, if users touch the key, we put system to s2ram status.
