   3 Required properties:
   4  - regulator-name: should be "buck1", ..., "buck8" and "ldo1", ..., "ldo7" for
   5                    BD71837. For BD71847 names should be "buck1", ..., "buck6"
   6                    and "ldo1", ..., "ldo6"
   7
   8 List of regulators provided by this controller. BD71837 regulators node
   9 should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at
  10 Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.txt
  11 Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
  12 definition for each of these nodes is defined using the standard
  13 binding for regulators at
  14 Documentation/devicetree/bindings/regulator/regulator.txt.
  15 Note that if BD71837 starts at RUN state you probably want to use
  16 regulator-boot-on at least for BUCK6 and BUCK7 so that those are not
  17 disabled by driver at startup. LDO5 and LDO6 are supplied by those and
  18 if they are disabled at startup the voltage monitoring for LDO5/LDO6 will
  19 cause PMIC to reset.
  20
  21 The valid names for BD71837 regulator nodes are:
  22 BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8
  23 LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7
  24
  25 The valid names for BD71847 regulator nodes are:
  26 BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6
  27 LDO1, LDO2, LDO3, LDO4, LDO5, LDO6
