      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

      pda_power: Remove ac_draw_failed goto and label · c10a002a
      由 Paul Parsons 提交于 
      A previous patch added the ac_draw_failed goto and label to
pda_power_probe(). The goto would be invoked after a failed call to
regulator_get().

However the way ac_draw is used - always after a check for NULL - suggests
that a failed call to regulator_get() was not fatal.

This patch removes the ac_draw_failed goto and label, partly reverting the
previous patch.

This patch also removes the assignment of an error code to ret after a
failed call to regulator_get(), since the error code is now never used.

      charger-manager: Add support sysfs entry for charger · 3950c786
      由 Chanwoo Choi 提交于 
      This patch add support sysfs entry for each charger(regulator).
Charger-manager use one or more chargers for charging battery but some
charger isn't necessary on specific scenario. So, if some charger isn't
needed, can disable specific charger through 'externally_control' entry
while system is on state and confirm the information(name, state) of
charger.

The list of added sysfs entry
- /sys/class/power_supply/battery/chargers/charger.[index]/name
  show name of charger(regulator)
- /sys/class/power_supply/battery/chargers/charger.[index]/state
  show either enabled or disabled state of charger
- /sys/class/power_supply/battery/chargers/charger.[index]/externally_control

If 'externally_control' of specific charger is 1, Charger-manager cannot
enable regulator for charging when charger cable is attached and charger
must be maintained with disabled state. If 'externally_control' is zero,
Charger-manager usually can control to enable/disable regulator.
