Why pass in parent instead of the rtc?

Either way, this is likely not an acceptable interface for this as
Alexandre already mentioned.
As I already suggested, I think you submit this as part of the PM work
adding support for entering the TI RTC-only mode. That will hopefully
provide enough context to be able to determine the right interface.
Note that this also means that we shouldn't split the current rtc-omap
power-off handler before this has been settled (i.e. patches 2/4 and 4/4
should not be applied before then).
Thanks,
Johan
