| 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. |

| 46 | May be 0 for disabling the ramp delay on BUCK{1,2,3,4}. |
| 47 | |
| 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}. |
