   1TPS51632 Voltage regulators
   2
   3Required properties:
   4- compatible: Must be "ti,tps51632"
   5- reg: I2C slave address
   6
   7Optional properties:
   8- ti,enable-pwm-dvfs: Enable the DVFS voltage control through the PWM interface.
   9- ti,dvfs-step-20mV: The 20mV step voltage when PWM DVFS enabled. Missing this
  10        will set 10mV step voltage in PWM DVFS mode. In normal mode, the voltage
  11        step is 10mV as per datasheet.

  13Any property defined as part of the core regulator binding, defined in
  14regulator.txt, can also be used.

  16Example:
  17
  18        tps51632 {
  19                compatible = "ti,tps51632";
  20                reg =  <0x43>;
  21                regulator-name = "tps51632-vout";
  22                regulator-min-microvolt = <500000>;
  23                regulator-max-microvolt = <1500000>;
  24                regulator-boot-on;
  25                ti,enable-pwm-dvfs;
  26                ti,dvfs-step-20mV;
  27        };
