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

# 3, 4, and 5 | supported (**)

#(*) LPSR and SUSPEND states use same voltage but both states have own
# enable /
# disable settings. Voltage 0 can be specified for a state to make
# regulator disabled on that state.
#
#(**) All states use same voltage but have own enable / disable
# settings. Voltage 0 can be specified for a state to make
# regulator disabled on that state.
