| The S2MPA01 provides buck and LDO regulators. |

| 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}. |
