   1 ROHM BD71837 Power Management Integrated Circuit (PMIC) regulator bindings

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