description: |
This is a part of device tree bindings for S2M and S5M family of Power
Management IC (PMIC).
The S2MPA01 provides buck and LDO regulators.
See also Documentation/devicetree/bindings/mfd/samsung,s2mpa01.yaml for
additional information and example.

enum: [0, 6250, 12500, 25000, 50000]
default: 12500
description: |
May be 0 for disabling the ramp delay on BUCK{1,2,3,4}.
In the absence of the regulator-ramp-delay property, the default ramp
delay will be used.
Note: Some bucks share the ramp rate setting i.e. same ramp value
will be set for a particular group of bucks so provide the same
regulator-ramp-delay value for them.
Groups sharing ramp rate:
* buck{1,6},
* buck{2,4},
* buck{8,9,10}.
