I had troubles to follow the rtc_wakeup initialization cleanup but it
seems OK.

Probably, once we have complete PM support ready then it would be
easier to understand. I think as of now lets have this minimal code for
rtc_wakeup.

However, I'm wondering why you are adding DT support as this
will always be probed from the MFD driver which pass the platform_data
and avoids that allocation.

You are right.

Originally, it was cleanup patch,

  - remove pm80x_pdata
  - Add check for pdata and np
  - and around rtc_wakeup

While doing that I added this nice to have allocation.

Thanks,
