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.

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.
54          Groups sharing ramp rate:
55            * buck{1,6},
