+ This module is part of the ROHM BD96801 MFD device. For more details
+ see Documentation/devicetree/bindings/mfd/rohm,bd96801-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 BD96801 regulator nodes are
+ BUCK1, BUCK2, BUCK3, BUCK4, LDO5, LDO6, LDO7
