   1 * Maxim MAX8973 Voltage Regulator
   2
   3 Required properties:
   4
   5 - compatible:   must be one of following:
   6                         "maxim,max8973"
   7                         "maxim,max77621".
   8 - reg:          the i2c slave address of the regulator. It should be 0x1b.
   9
  10 Any standard regulator properties can be used to configure the single max8973
  11 DCDC.
  12
  13 Optional properties:
  14
  15 -maxim,externally-enable: boolean, externally control the regulator output
  16                 enable/disable.
  17 -maxim,enable-gpio: GPIO for enable control. If the valid GPIO is provided
  18                 then externally enable control will be considered.
  19 -maxim,dvs-gpio: GPIO which is connected to DVS pin of device.
  20 -maxim,dvs-default-state: Default state of GPIO during initialisation.
  21                 1 for HIGH and 0 for LOW.
  22 -maxim,enable-remote-sense: boolean, enable reote sense.
  23 -maxim,enable-falling-slew-rate: boolean, enable falling slew rate.
  24 -maxim,enable-active-discharge: boolean: enable active discharge.
  25 -maxim,enable-frequency-shift: boolean, enable 9% frequency shift.
  26 -maxim,enable-bias-control: boolean, enable bias control. By enabling this
  27                 startup delay can be reduce to 20us from 220us.

  29 Example:
  30
  31         max8973@1b {
  32                 compatible = "maxim,max8973";
  33                 reg = <0x1b>;
  34
  35                 regulator-min-microvolt = <935000>;
  36                 regulator-max-microvolt = <1200000>;
  37                 regulator-boot-on;
  38                 regulator-always-on;
  39         };
