      Fix build errors in lp8788-charger by making it depend on IIO.
Fixes errors when CONFIG_IIO=m and CHARGER_LP8788=y.

      power_supply: Add support for tps65090-charger · 6f8da5df
      由 Rhyland Klein 提交于 
      This patch adds support for the tps65090 charger driver. This driver is
responsible for controlling the charger aspect of the tps65090 mfd.
Currently, this mainly consists of turning on and off the charger, but
some features of the charger can be supported through this driver
including:

- Enable Auto Recharge based on Battery voltage
- Fast Charge Safety Timer
- Maximum battery discharge current
- Maximum battery adapter current
- Enable External Charge
- Disable charging termination based on low charger current (supported)

Once the driver is accepted, later patches can add support for the
features above which are not yet supported.

      power: battery: Generic battery driver using IIO · e60fea79
      由 anish kumar 提交于 
      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.

In V1:
Addressed concerns raised by Anton:
a. changed the struct name to gab(generic adc battery).
b. Added some functions to neaten the code.
c. Some minor coding guidelines changes.
d. Used the latest function introduce by lars:
   iio_read_channel_processed to streamline the code.

In V2:
Addressed concerns by lars:
a. No need of allocating memory for channels.Make it array.
b. Code restructring, coding style and following kernel guidelines changes
   suggested by him.

In V3:
Addressed conerns by Anton:
a. Added the copyright.
b. Coding guidelines changes suggested by him.
c. Added Makefile and Kconfig

      power_supply: Enable battery-charger for 88pm860x · a830d28b
      由 Jett.Zhou 提交于 
      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.

      power_supply: Add new lp8788 charger driver · 98a27664
      由 Kim, Milo 提交于 
      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.

      smb347-charger: Convert to regmap API · 34298d40
      由 Mika Westerberg 提交于 
      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.

      There are some problems with MFD part of this driver, so the

drivers/power/da9052-battery.c:293:2: error: implicit declaration of function 'da9052_adc_manual_read' [-Werror=implicit-function-declaration]

drivers/power/da9052-battery.c:348:1: warning: control reaches end of non-void function [-Wreturn-type]
cc1: some warnings being treated as errors

The fix for MFD part will probably go post -rc1 (or in the next merge
window), so let's disable the driver for now.

      bq27x00: Add bq27000 support · 7fb7ba58
      由 Lars-Peter Clausen 提交于 
      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.
