All avs drivers have now been moved to their corresponding soc specific
directories. Additionally, they don't depend on the POWER_AVS Kconfig
anymore. Therefore, let's simply drop the drivers/power/avs directory

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

let's move them to udc-core and export them with
EXPORT_SYMBOL_GPL, that way we can make sure that

Currently the reset/power off handlers (POWER_RESET) and Adaptive Voltage
Scaling class (POWER_AVS) are not built when POWER_SUPPLY is disabled.
The POWER_RESET is also not visible in drivers main section of config.However they do not really depend on power supply so they can be built
always. The objects for power supply drivers already depend on
particular Kconfig symbols so there is no need for any changes in
drivers/power/Makefile.This allows selecting POWER_RESET from main drivers config section and
fixes following build warning (encountered on ARM exynos defconfig when
POWER_SUPPLY is disabled manually):warning: (ARCH_HISI && ARCH_INTEGRATOR && ARCH_EXYNOS && ARCH_VEXPRESS && REALVIEW_DT) selects POWER_RESET which has unmet direct dependencies (POWER_SUPPLY)

This patch adds basic support for bq24250 and bq24251 which are very
similar to the bq24257 the driver was originally written for. Basic
support means the ability to select a device through Kconfig, DT and
ACPI, an instance variable allowing to check which chip is active, and
the reporting back of the selected device through the model_name power
supply sysfs property.This patch by itself is not sufficient to actually use those two added
devices in a real-world setting due to some feature differences which
are addressed by other patches in this series.Signed-off-by: Andreas Dannenberg

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
