 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
