13  List of regulators provided by this controller. BD71847 regulators node
14  should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at
15  Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml
16  Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
17  definition for each of these nodes is defined using the standard
18  binding for regulators at
19  Documentation/devicetree/bindings/regulator/regulator.txt.
20  Note that if BD71847 starts at RUN state you probably want to use
21  regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must
22  not be disabled by driver at startup. If BUCK5 is disabled at startup the
23  voltage monitoring for LDO5/LDO6 can cause PMIC to reset.
24
25#The valid names for BD71847 regulator nodes are:
26#BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6
27#LDO1, LDO2, LDO3, LDO4, LDO5, LDO6
