   1 Fixed Voltage regulators

   3 Required properties:
   4 - compatible: Must be "regulator-fixed";
   5
   6 Optional properties:
   7 - gpio: gpio to use for enable control
   8 - startup-delay-us: startup time in microseconds
   9 - enable-active-high: Polarity of GPIO is Active high
  10 If this property is missing, the default assumed is Active low.
  11 - gpio-open-drain: GPIO is open drain type.
  12   If this property is missing then default assumption is false.
  13
  14 Any property defined as part of the core regulator
  15 binding, defined in regulator.txt, can also be used.
  16 However a fixed voltage regulator is expected to have the
  17 regulator-min-microvolt and regulator-max-microvolt
  18 to be the same.

  20 Example:
  21
  22         abc: fixedregulator@0 {
  23                 compatible = "regulator-fixed";
  24                 regulator-name = "fixed-supply";
  25                 regulator-min-microvolt = <1800000>;
  26                 regulator-max-microvolt = <1800000>;
  27                 gpio = <&gpio1 16 0>;
  28                 startup-delay-us = <70000>;
  29                 enable-active-high;
  30                 regulator-boot-on;
  31                 gpio-open-drain;
  32         };
