clocksource/drivers/timer-ti-dm: Add missing set_state_oneshot_stopped
To avoid spurious timer interrupts when KTIME_MAX is used, we need to configure set_state_oneshot_stopped(). 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()"). Fixes: 52762fbd1c47 ("clocksource/drivers/timer-ti-dm: Add clockevent and clocksource support") Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20210304072135.52712-4-tony@atomide.com
