  13   This is a part of device tree bindings for S2M and S5M family of Power
  14   Management IC (PMIC).
  15
  16   The S2MPA01 provides buck and LDO regulators.
  17
  18   See also Documentation/devicetree/bindings/mfd/samsung,s2mpa01.yaml for
  19   additional information and example.

  48           In the absence of the regulator-ramp-delay property, the default ramp
  49           delay will be used.

  51           Note: Some bucks share the ramp rate setting i.e. same ramp value
  52           will be set for a particular group of bucks so provide the same
  53           regulator-ramp-delay value for them.
