AM335X can not power off



Hi,

I am developing a board using the AM335X chip and power ic tps65910a3. I want to power off the target. But I

failed to get that.  rtc_power_off is called ,but I  can't find the alarm2 works. It doesnt raise any interrupt.

The RTC is working using the internal  clock.Please give me some advise. Many thanks!
