The max8998 has a current regulator for charging control. The charger driver in drivers/power/supply/max8998_charger.c has a comment in it stating that 'charger control is done by a current regulator "CHARGER"', but this regulator was never added until now. The current values have been extracted from a downstream driver for the SGH-T959V.
