Hi, Andrew. Thanks for comment. "Issue" is that alarmtimer won't be registered
if tps6586x is the only wakeup compatible rtc in the system.

from kernel/time/alarmtimer.c:

static int alarmtimer_rtc_add_device(struct device *dev,
struct class_interface *class_intf)
{
...
if (!device_may_wakeup(rtc->dev.parent)) // dev.parent = tps6586x rtc
return -1;

I've sent V2 with changed description.
