| 13 | + Regulator nodes should be named to BUCK_<number> and LDO_<number>. The |
| 14 | + definition for each of these nodes is defined using the standard |
| 15 | + binding for regulators at |
| 16 | + Documentation/devicetree/bindings/regulator/regulator.txt. |
| 17 | + Datasheet is available at |

| 22 | +#LDO1, LDO2, LDO3, LDO4, LDO5 |
| 23 | +#Note: Buck3 removed on PCA9450B and connect with Buck1 on PCA9450C. |
