ded7fc7b05 power_supply: Add DA9052 battery driver
Driver for DA9052 battery charger. This driver depends on DA9052 MFD core
dirver for definitions and methods.

This patch is functionally tested on Samsung SMDKV6410.

c78f2b6496 bq20z75: Rename to sbs-battery
This driver for the bq20z75 implemented the register spec defined
by the SBS standard. As this is not unique to this the TI part this
was originally written for, we can generalize this driver to
show its support for any SBS compliant battery.

3bb3dbbd56 power_supply: Add initial Charger-Manager driver
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
in-suspend monitoring.

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

275ac74629 w1: add Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC support
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.

359ab9f5b1 power_supply: Add MAX17042 Fuel Gauge Driver
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.

14431aa0c5 power_supply: Add support for WM8350 PMU
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.

This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.
