| Regulator nodes should be named to BUCK_<number> and LDO_<number>. The |
| definition for each of these nodes is defined using the standard |
| binding for regulators at |
| Documentation/devicetree/bindings/regulator/regulator.txt. |
| Datasheet is available at |
| https://www.nxp.com/docs/en/data-sheet/PCA9450DS.pdf |

| # The valid names for PCA9450 regulator nodes are: |
| # BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, |
| # LDO1, LDO2, LDO3, LDO4, LDO5 |
| # Note: Buck3 removed on PCA9450B and connect with Buck1 on PCA9450C. |
