I'm not sure this rename is a good idea (or the original wild
card was for that matter).
For example, just a quick look at the xpowers website shows there is a AXP228
which just got swept up by the name change.
Best plan, in my view, is to always name a driver after an individual part it
supports and rely on Kconfig description to say what else is supported.
Bit late here, but perhaps best not to make things worse!
