1ROHM BD71837 Power Management Integrated Circuit (PMIC) regulator bindings
2
3Required properties:
4 - regulator-name: should be "buck1", ..., "buck8" and "ldo1", ..., "ldo7"
5
6List of regulators provided by this controller. BD71837 regulators node
7should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at
8Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.txt
9Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
10definition for each of these nodes is defined using the standard
11binding for regulators at
12Documentation/devicetree/bindings/regulator/regulator.txt.
13Note that if BD71837 starts at RUN state you probably want to use
14regulator-boot-on at least for BUCK6 and BUCK7 so that those are not
15disabled by driver at startup. LDO5 and LDO6 are supplied by those and
16if they are disabled at startup the voltage monitoring for LDO5/LDO6 will
17cause PMIC to reset.

19The valid names for regulator nodes are:
20BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8
21LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7
