title: Maxim MAX8998, National/TI LP3974 Power Management IC
maintainers:
- Krzysztof Kozlowski <krzk@kernel.org>
description:
The Maxim MAX8998 is a Power Management IC which includes voltage/current
regulators, real time clock, battery charging controller and several other
sub-blocks. It is interfaced using an I2C interface. Each sub-block is
addressed by the host system using different i2c slave address.
