6 - compatible : must be "vctrl-regulator".
7 - regulator-min-microvolt : smallest voltage consumers may set
8 - regulator-max-microvolt : largest voltage consumers may set
9 - ctrl-supply : The regulator supplying the control voltage.
10 - ctrl-voltage-range : an array of two integer values describing the range
11 (min/max) of the control voltage. The values specify
12 the control voltage needed to generate the corresponding
13 regulator-min/max-microvolt output voltage.
