clocksource/drivers/timer-ti-dm: Do not update counter on updating the period commit aff7665dc64b60c1f93d6e52fde297ae6b8999ae upstream. Write to trigger register(OMAP_TIMER_TRIGGER_REG) will load the value in Load register(OMAP_TIMER_LOAD_REG) into Counter register (OMAP_TIMER_COUNTER_REG). omap_dm_timer_set_load() writes into trigger register every time load register is updated. When timer is configured in pwm mode, this causes disruption in current pwm cycle, which is not expected especially when pwm is used as PPS signal for synchronized PTP clocks. So do not write into trigger register on updating the period.
