How does one do these things in a non-dt context? Platform data? I'd let
the MFD select the 'mode'. Maybe being backwards compatible isn't
possible in any case. Is there a rule somewhere that we guarantee you'll
never have to change your CONFIG_FOO options?

I suck at communicating these days. But yeah. That was basically my
concern when I split it up into 'Fixes' and 'Rework'.

Mostly since the rework might take a couple of rounds of review, while the
fix can unbrick stuff (might still need review of course)
