ROHM BD70528 Power Management Integrated Circuit regulator bindings
Required properties:
- regulator-name: should be "buck1", "buck2", "buck3", "ldo1", "ldo2", "ldo3",
"led_ldo1", "led_ldo2"
List of regulators provided by this controller. BD70528 regulators node
should be sub node of the BD70528 MFD node. See BD70528 MFD bindings at
Documentation/devicetree/bindings/mfd/rohm,bd70528-pmic.txt
The valid names for BD70528 regulator nodes are:
BUCK1, BUCK2, BUCK3, LDO1, LDO2, LDO3, LED_LDO1, LED_LDO2
