Thanks, Hans. I really should have figured that out on my own!

Do you think it's worth asking PeterR if he will change the default
Fedora armv7 config to CONFIG_REGULATOR_AXP20X=y rather than the
current CONFIG_REGULATOR_AXP20X=m? (I suspect that request might
carry more weight if it comes from you rather than me. ;)

Hans,

Do you have an opinion, (or anyone else for that matter), on what would be the upstream preferred way of getting the axp20x regulator driver to auto-load, from a DT reference, assuming it is built as a module? Something like the attached patch? (Not tested, just thinking out loud.)

Regards
