description:
  This is a device tree bindings for S2DOS family of Power Management IC (PMIC).

  The S2DOS05 is a companion power management IC for the panel and touchscreen
  in smart phones. Provides voltage regulators and
  ADC for power/current measurements.

  Regulator section has 4 LDO and 1 BUCK regulators and also
  provides ELVDD, ELVSS, AVDD lines.
