It is optimized +for low BOM cost and compact solution footprint. It +integrates 8 Buck regulators and 7 LDO’s to provide all +the power rails required by the SoC and the commonly +used peripherals. + +Required properties: + - compatible: should be "rohm,bd71837-pmic". + - regulator-name: should be "buck1", ..., "buck8" and "ldo1", ..., "ldo7" + +List of regulators provided by this controller.
