   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.
   50 
   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.
   54           Groups sharing ramp rate:
   55             * buck{1,6},
   56             * buck{2,4},
   57             * buck{8,9,10}.
