modify this driver's behavior.
Thanks
Lee, Zhuo-hao
design the
driver to reduce this periodic interrupt.
The following call path enable hpet timer when system go to suspend, just for
you reference :)
alarmtimer_suspend
--rtc_timer_start
rtc_timer_enqueue
--__rtc_set_alarm
----cmos_set_alarm
--cmos_irq_enable
hpet_s
will trigger hpet_rtc_interrupt continuously until timer
timeout.
This patch only fixed (1). Fixing (1) can avoid (2).
However, The (2) is another story which it is not covered by this patch.
Thanks
Lee, Zhuo-hao
