27 description: GPIO to use to enable/disable the regulator.
28 Warning, the GPIO phandle flags are ignored and the GPIO polarity is
29 controlled solely by the presence of "enable-active-high" DT property.

39 gpios-states:
41 On operating systems, that don't support reading back gpio values in
42 output mode (most notably linux), this array provides the state of GPIO
43 pins set when requesting them from the gpio controller. Systems, that are

58 no states in the "states" array, use a fixed regulator instead.
