description: |
  This module is part of the ROHM BD72720 MFD device. For more details
  see Documentation/devicetree/bindings/mfd/rohm,bd72720-pmic.yaml.

  The regulator controller is represented as a sub-node of the PMIC node
  on the device tree.

  Regulator nodes should be named to BUCK_<number> and LDO_<number>.
  The valid names for BD72720 regulator nodes are
  buck1, buck2, buck3, buck4, buck5, buck6, buck7, buck8, buck9, buck10
  ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10, ldo11

          with the offset voltage given here. This will improve the LDO efficiency.
