13 List of regulators provided by this controller. BD71837 regulators node
14 should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at
15 Documentation/devicetree/bindings/mfd/rohm,bd71837-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 BD71837 starts at RUN state you probably want to use
21 regulator-boot-on at least for BUCK6 and BUCK7 so that those are not
22 disabled by driver at startup. LDO5 and LDO6 are supplied by those and
23 if they are disabled at startup the voltage monitoring for LDO5/LDO6 will

27 #BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8
28 #LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7
