| 13 | This module is part of the ROHM BD71828 MFD device. For more details |
| 14 | see Documentation/devicetree/bindings/mfd/rohm,bd71828-pmic.yaml. |
| 15 | |
| 16 | The regulator controller is represented as a sub-node of the PMIC node |
| 17 | on the device tree. |
| 18 | |
| 19 | Regulator nodes should be named to BUCK_<number> and LDO_<number>. |
| 20 | The valid names for BD71828 regulator nodes are |
| 21 | BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7 |
| 22 | LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7 |
