mfd: rohm-bd71828: Support ROHM BD72720

Browse source

The ROHM BD72720 is a power management IC which continues the BD71828
family of PMICs. Similarly to the BD71815 and BD71828, the BD72720
integrates regulators, charger, RTC, clock gate and GPIOs.

The main difference to the earlier PMICs is that the BD72720 has two
different I2C slave addresses. In addition to the registers behind the
'main I2C address', most of the charger (and to some extent LED) control
is done via registers behind a 'secondary I2C slave address', 0x4c.
