mfd: bd71828: Support ROHM BD71828 PMIC - core
BD71828GW is a single-chip power management IC for battery-powered portable devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA single-cell linear charger. Also included is a Coulomb counter, a real-time clock (RTC), 3 GPO/regulator control pins, HALL input and a 32.768 kHz clock gate. Add MFD core driver providing interrupt controller facilities and i2c access to sub device drivers.
