| 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}. |
