This module is part of the ROHM BD71828 MFD device. For more details
see Documentation/devicetree/bindings/mfd/rohm,bd71828-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 BD71828 regulator nodes are
BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7
LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7
