This patch adds driver for Zipit Z2 battery chip called AER915. No
details are known about the chip. The chip is available through I2C bus
at address 0x55 and it's register 0x02 contains battery voltage.

BQ27500 is newer fuel gauge chip from TI with slightly changed
register layout and some different register semantics. Add new i2c
ID for it and handle differences where needed. Also rename bq27200
functions to bq27x00, as they are no longer bq27200 specific.

This driver is based on tosa_battery.c.

The backup battery on WM831x is a separate IP block to the main PMU
and is largely unrelated to the main supply functionality. Factor it
out into a separate driver in order to reflect this and better support
future hardware versions.

The WM831x PMICs provide power path management from three sources:
a wall supply, USB and a battery with integrated charger. They also
provide an additional backup supply with integrated for maintaining
always on functionality such as the RTC and monitoring of power
switches.

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

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.

It needs the WM97xx touchscreen driver to be compiled in, not as a

These battery managers came in two different packages: one for I2C
busses (BQ27200) and one for HDQ busses (BQ27000).

This driver currently supports only the I2C chip version but the code
is designed in order to easily allow the HDQ chip version integration.

As reported by Stephen Rothwell, an allmodconfig build on 64-bit
PowerPC reports these errors:

ERROR: "pmu_batteries" [drivers/power/pmu_battery.ko] undefined!
ERROR: "pmu_battery_count" [drivers/power/pmu_battery.ko] undefined!
ERROR: "pmu_power_flags" [drivers/power/pmu_battery.ko] undefined!

This fixes the problem by not building pmu_battery.ko on ppc64.  There
are no battery-powered ppc64 machines with an Apple PMU, and we can be
reasonably confident there never will be.

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.
