I'm sorry, you did a great job on this PMIC driver, but this is just wrong. I'm completely fine with the names. What I'm not fine with is all this "one common DT representation across all boards". Pretty much all the boards are wired differently when it comes to regulators. Why do you want to just do some copy pasting without any checking on the schematics side if not just for the joy of duplicating code? > > I guess you need some more refining on this patch. > > Ok, I'll submit a v6 only for this patch. Please, please, *please* make sure that the informations you put in there are actually accurate.
