Perhaps gpio-keys could come before the fixed regulators to keep it a bit more sane/sorted?

Are you sure you can't get USB3 in host mode? Perhaps it's not worth discarding it upfront, as some boards can do that, definitely do check!

Please add a newline.


The DTS files look correct, but don't you need at least one of msm-id, board-id, pmic-id? I'm not exactly sure what OnePlus does, but I can imagine they would require such properties..
