Although implementing this is optional, it still affects things like power management for the extra timer interrupt. For more information, please see commit 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state") and commit cf8c5009ee37 ("clockevents/drivers/arm_arch_timer: Implement ->set_state_oneshot_stopped()").
