I'll split up the patches so that reviewing is easier. For the base
patch, would you prefer that I remove *all* mode support (handled by
generic regulator framework DT properties) or only remove the special
purpose drms mode handling support (i.e. qcom,regulator-drms-modes and
qcom,drms-mode-max-microamps)?

Thanks,
David
