Say Y here to enable RT9467 Battery Charger.
RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger
for portable applications. It integrates a synchronous PWM controller,
power MOSFETs, input current sensing and regulation, high-accuracy
voltage regulation, and charge termination. The charge current is
regulated through integrated sensing resistors. It also features
USB On-The-Go (OTG) support and integrates D+/D- pin for USB
host/charging port detection.
This driver can also be built as a module. If so, the module
will be called "rt9467-charger".

help
Battery monitor driver for the uPI uG3105 battery monitor.
Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead
it is expected to be use in combination with some always on
microcontroller reading its coulomb-counter before it can wrap
(it must be read every 400 seconds!).
Since Linux does not monitor coulomb-counter changes while the
device is off or suspended, the functionality of this driver is
limited to reporting capacity only.
