There are charger and battery measurement feature for 88pm860x PMIC.

For charger, it can support pre-charge with small current when battery is
nearly exausted and then changed into fast-charge with CC&CV mode.

For battery monitor, it can support battery measurement such as
vbat,vsys,vchg and ibat etc,it can aslo accumulating the Coulomb value
charged or discharged from battery based on Conlomb Counter, we use it
to estimate battery capacity.

TI LP8788 PMU supports regulators, battery charger, RTC, ADC, backlight
driver and current sinks.

This patch supports the charger operations including the charger
interrupt handling.

The LP8788 charger driver provides configurable platform data.  The
charger platform data includes ADC input ID, maximum battery voltage,
charging parameters and etc.

The ADC input is used for getting the battery voltage and temperature.
Charging parameters are used for updating the charger operations such
like setting charging current and setting End-of-charge conditions.

When the charging interrupt occurs, power supply uevents are generated
in order to update the user-space information.  For platform specific
charger action, the charger_event() function can be used in the
platform side.

The build is controlled by the following Kconfig options:
 . CONFIG_POWER_AVS: general knob for Adaptive Voltage Scaling support,
 . CONFIG_POWER_AVS_OMAP: AVS(Adaptive Voltage Scaling)
   support on OMAP containing the version 1 or version 2 of the SmartReflex IP,

Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide

This patch allows to monitor battery health in-suspend state.

Add support for the Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC.

It was suggested to combine this functionality with the current ds2782
driver.  Unfortunately, I'm unable to commit the time to refactoring this
driver to that extent and I don't have a platform with the ds2782 part to
validate that there are no regression issues by adding this functionality.

The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.

This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.

This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
The hardware functions largely autonomously, with minimal software
control required to initiate fast charging.

Support for configuration of the USB supply is not yet implemented.
This means that the hardware will remain in the mode configured at
startup, by default limiting the current drawn from USB to 100mA.
