Hi Thomas,
Ingo suggested [1] to keep CLOCK_EVT_STATE_* symbols somewhere in kernel/time/. We couldn't do it as bL_switcher code was using it earlier. But that's fixed now. And so the first patch moves these symbols to tick-internal.h.
Some of the drivers [2] need to verify state of the clockevent device from their callbacks or interrupt handlers.
Because these symbols (defined by 'enum clock_event_state') will now be internal to the core, we need some helpers to verify state of a clockevent device.
One way out was to maintain the state in drivers as well, but that would be unnecessary burden on them. And so the second patch introduces helpers for these states.
Rebased-over: tip/timers/core (dependency on 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state"))
