A sub node within the + device node descrbe the properties of these regulators. The sub-node + names must be as follows: + -For regulator outp, the sub node name should be "outp". + -For regulator outn, the sub node name should be "outn". + +-ti,enable-gpio: Regulators are controlled by the input pins.
