From: Viresh Kumar <[email protected]> Migrate powerpc driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now.
This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We weren't doing anything in ->set_mode(ONSHOT) and so set_state_oneshot() isn't implemented.
