5789451713 power_supply: Makefile cleanup
Replace EXTRA_CFLAGS with ccflags-y; remove if-statements and replace
with lists using the kbuild idiom.

None of the dependencies are modified.

a wall supply, USB and a battery with integrated charger. They also
provide an additional backup supply with integrated for maintaining

switches.

After some initial configuration at startup the device operates
autonomously, the driver simply provides reporting of the current
state.

14431aa0c5 power_supply: Add support for WM8350 PMU
This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
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
startup, by default limiting the current drawn from USB to 100mA.

This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.

b2998049cf [BATTERY] pda_power platform driver
Common power driver for PDAs and phones with one or two external
power supplies (AC/USB) connected to main and backup batteries,
and optional builtin charger.

It's used to stop logic duplication through different embedded
devices. So, power supply *logic* is here. pda_power register
power supplies, and will take care about notifying batteries
about power changes through external power interface.

Currently, power consumption legal limits (including USB power
consumption) should be handled by platform code, inside set_charge
function.
