The last sentence tries to say this but it should be stated more clearly. - Clarify which "gpio settings" must be the same, e.g. polarity I guess. Yours, Linus Walleij

At the gpio-based regulator enable/disable documentation. This property can be applied to each subnode within the 'regulators' node so each regulator can be configured differently.
