is this power-off feature "RTC-only mode" ?

Yes, I believe so, at least as long as RTC power is maintained. The
pmic_power_en pin can otherwise still be used to power off. 

On the BeagleBone the PMIC can be configured to enter OFF or SLEEP mode
on power off, where the latter (and default) mode keeps the RTC power
supply enabled.

Thanks for the fast review, Felipe.

Great :) I assume adding the regulator support to this driver should
also help in the 35xx case?

If I remember correctly both OMAP and Sitara 35xx have no on-chip RTC so
they won't be using this driver.

Sorry I made a typo.. I meanto to ask if adding the regulator
helps in your 335x case (not 35xx case)?

Ah, sorry, that's what I first read before I noticed you wrote "35xx"
twice. :)

Yes, RTC power can be configured as a regulator on am33xx (e.g. provided
by LDO1 of the PMIC on BBB). I guess you would still need to configure
it as always-on to be able to use the RTC-only mode, though.
