Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This patch adds voltage regulator driver for Maxim 8998 chip. This chip
is used on Samsung Aquila and GONI boards and provides following
functionalities:
- 4 BUCK voltage converters, 17 LDO power regulators and 5 other power
  controllers
- battery charger

This patch adds basic driver for voltage regulators and MAX 8998 MFD core.
