This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.Signed-off-by: Sebastian Reichel

This adds a driver for the usb power_supply bits of the axp20x PMICs.
I initially started writing my own driver, before coming aware of
Bruno Prémont's excellent earlier RFC with a driver for this.My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's
drvier has, so I've copied the code for those from his driver.Note that the AC-power-supply and battery charger bits will need separate
drivers. Each one needs its own devictree child-node so that other
devicetree nodes can reference the right power-supply, and thus each one
will get its own mfd-cell / platform_device and platform-driver.Cc: Bruno Prémont

LTC2941 instead of LTC294X.v2: Fix units of measurement: uV, uA and centidegrees.

Add driver support for the Texas Instruments BQ24190 battery charger.
Some of the information provided by the device is about the charger and
other information is about the battery so create two power_supply objects
(one for each) and provide the appropriate information for each one.The device has many fields that go beyond what is reasonable to report or
modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver
exports the register fields via sysfs. They are prefixed by 'f_' (for
'field') to make it easier to distinguish between a register field and a
"normal" sysfs file exported by the power_supply infrastructure.Signed-off-by: Mark A. Greer

Driver to allow use of the ADC drivers supported by the IIO

driver to the relevant IIO device requires registration of

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:

charger platform data includes ADC input ID, maximum battery voltage,

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.Signed-off-by: Milo(Woogyom) Kim
