Hi Kevin,

I've made the argument that to me this is conceptually a black box
handling regulators, clocks and other stuff; hence similar to a PMIC,
which would fit nicely into drivers/mfd.

I still think this is the case and now that I look back I didn't get
any pushback from Lee Jones so maybe the move was premature?

Regards,
Bjorn
