Right - I know - but none of the subdevs are currently using this
functionality.

Right - and I didn't say that I'm not going to add this functionality
later.
All the ADP5520 subdevs already merged in 2.6.32 - the MFD core is the
only remaining part.
Time is running short and major changes are going to require another
round of full testing.
