23   In the above example, three GPIO pins are used for controlling the regulator:
25     * third for enabling/disabling the regulator.

42   regulator-name:
46     type: phandle-array
49       GPIO to use to switch voltage.
54       Selection of available voltages provided by this regulator and matching
55       GPIO configurations to achieve them. If there are no states in the
56       "states" array, use a fixed regulator instead. First value in an array
57       item is voltage in microvolts and the second is GPIO group state value.
59   enable-gpios:
60     type: phandle-array
62       GPIO to use to enable/disable the regulator.
64       Unlike the gpio property in the Linux bindings this array must provide
65       the GPIO polarity and open-drain status in the phandle selector. The
66       Linux enable-active-high and gpio-open-drain properties are not valid
68       working with more than one GPIO and this property does not have a state
69       array. The driver simply sets or clears the appropriate GPIO bit when
70       it is requested to enable or disable the regulator.
73         enable-gpios = <&gpio5 2 GPIO_ACTIVE_HIGH>;
