Merge branch 'ARM/clkevt/set-state-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/linux into next/cleanup

Merge "ARM: clockevents: Migrate to 'set-state' callbacks" from Viresh Kumar:

This series migrates ARM clockevent drivers (present in arch/arm/
directory), to the new set-state interface. This would enable these
drivers to use new states (like: ONESHOT_STOPPED, etc.) of a clockevent
device (if required), as the set-mode interface is marked obsolete now
and wouldn't be expanded to handle new states.
