-ROHM BD71837 and BD71847 Power Management Integrated Circuit regulator bindings
-
-Required properties:
- - regulator-name: should be "buck1", ..., "buck8" and "ldo1", ..., "ldo7" for
-                   BD71837. For BD71847 names should be "buck1", ..., "buck6"
-		   and "ldo1", ..., "ldo6"
-
-List of regulators provided by this controller. BD71837 regulators node
-should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at
-Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.txt
-Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
-definition for each of these nodes is defined using the standard
-binding for regulators at
-Documentation/devicetree/bindings/regulator/regulator.txt.
-Note that if BD71837 starts at RUN state you probably want to use
-regulator-boot-on at least for BUCK6 and BUCK7 so that those are not
-disabled by driver at startup. LDO5 and LDO6 are supplied by those and
-if they are disabled at startup the voltage monitoring for LDO5/LDO6 will
-cause PMIC to reset.
-
-The valid names for BD71837 regulator nodes are:
-BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8
-LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7
-
-The valid names for BD71847 regulator nodes are:
-BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6
-LDO1, LDO2, LDO3, LDO4, LDO5, LDO6
-
-Optional properties:
-- rohm,dvs-run-voltage		: PMIC default "RUN" state voltage in uV.
-				  See below table for bucks which support this.
-- rohm,dvs-idle-voltage		: PMIC default "IDLE" state voltage in uV.
-				  See below table for bucks which support this.
-- rohm,dvs-suspend-voltage	: PMIC default "SUSPEND" state voltage in uV.
-				  See below table for bucks which support this.
-- Any optional property defined in bindings/regulator/regulator.txt
