Driver to allow use of the ADC drivers supported by the IIO
subsystem for battery status monitoring. Connecting this
driver to the relevant IIO device requires registration of
the appropriate iio_map structure array by the IIO device
driver (usually from platform data). If specified the driver
will also make use of a gpio to provide interrupt driven
notification that the battery is fully charged.
In last version:
Addressed concerns raised by lars:
a. made the adc_bat per device.
b. get the IIO channel using hardcoded channel names.
c. Minor issues related to gpio_is_valid and some code
refactoring.

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.

all pretty straightforward, except one thing.
One of our patches added thermal support for power supply class, but
thermal/ subsystem changed under our feet. We (well, Stephen, that is)
caught the issue and it was decided[1] that I'd just delay the battery
pull request, and then will fix it up by merging upstream back into
battery tree at the specific commit.
That's not all though: another[2] small fixup for thermal subsystem was
needed to get rid of a warning in power supply subsystem (the warning
was not drivers/power's "fault", the thermal registration function just
needed a proper const annotation, which is also done by a small commit
on top of the merge.
So, to sum this up:
- The 'master' branch of the battery tree was in the -next tree for
weeks, was never rebased, altered etc. It should be all OK;
- Although, for-v3.6 tag contains the 'master' branch + merge + the
warning fix.

max17047 is improved version of max17042 chip. It has few HW bug
fixes with minor changes in register set.
max17050 is same as max17047 chip except its silicon packging. So from

This patch adds the support to dynamically detect the chip type and

The smb347-charger driver does a lot of read-modify-write to the device
registers. Instead of open-coding everything we can take advantage of
regmap API which provides nice functions to do this kind of things.
In addition there is no need for custom debugfs file for dumping
registers as this is already provided by the regmap API.

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.

This patch adds support for the bq27000 battery to the bq27x00 driver.
The bq27000 is similar to the bq27200 except that it uses the HDQ bus
instead of I2C to communicate with the host system.
The driver is implemented as a platform driver. The driver expects to be
provided with a read callback function through its platform data. The read
function is assumed to do the lowlevel HDQ handling and read out the value
of a certain register.

The MAX17042 is a fuel gauge with an I2C interface for lithium-ion

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.

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
