Just an FYI this worked for me on a BBG 4.4.68-ti-r108
$ sudo su
$ echo 0 > /sys/class/rtc/rtc0/wakealarm
$ echo `date '+%s' -d '+ 1 minutes'` > /sys/class/rtc/rtc0/wakealarm
$ echo standby > /sys/power/state
(shutsdown to 0.02A then wakesup on deadline or any other event…)

I discovered that a fix for the rtc-omap driver is missing in the 3.14.x-ti
code. This was preventing alarmtimer and other devices from detecting
rtc-omap as a valid wake-capable RTC... applying this patch fixed the issue
for me.

Sorry, I missed that the first time I read your post.

I can tell you that using kernel 4.1.x
https://www.linux.com/learn/wake-linux-rtc-alarm-clock works. I'm not sure
that rtc wake timer is related to the one you're asking. However, I can

I am trying to use power management (sleep mode) in a way that is similar
to how Android does it with timerfd and epoll. I want to enable autosleep
and use RTC wake timers (created using timerfd) that wake the system back
up and prevent sleep mode (using epoll mechanism) until the timer event
