359ab9f5b1 power_supply: Add MAX17042 Fuel Gauge Driver
The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.

This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.

bf542a4e7b olpc_battery: Fix up XO-1.5 properties list
The patches adding support for CURRENT_NOW, VOLTAGE_NOW, CHARGE_NOW and
CHARGE_FULL_DESIGN were based on a tree not including c566d299
("olpc_battery: Ambient temperature is not available on XO-1.5") and
therefore only modified the then-common, now-XO-1 properties list. This
patch adds the new properties to XO-1.5 as well.

{CURRENT,VOLTAGE}_AVG are actually {CURRENT,VOLTAGE}_NOW (the EC code

20fd9830cc olpc_battery: Add support for CHARGE_NOW
CHARGE_NOW is needed by some user space software (read: UPower) for
internal calculations.

This patch violates the power supply class definition (as we already
do for CAPACITY though it isn't as obvious there), but this is the best
we can do without adding rather sophisticated algorithms to either the EC
or UPower.

f3dcab70e1 jz4740-battery: Should include linux/io.h
During test-build (with disabled 'depends on') I found that
jz4740-battery driver lacks linux/io.h, which makes build break
like this (on x86):

  CC [M]  drivers/power/isp1704_charger.o
jz4740-battery.c: In function 'jz_battery_read_voltage':
jz4740-battery.c:84: error: implicit declaration of function 'readw’

This patch fixes the issues, and thus makes it easier to build-test
the driver for me.

26eb387265 gpio-charger: Fix potential race between irq handler and probe/remove
This patch fixes a potential race between the irq handler and the probe
and remove functions.

The irq should not be requested before the chargers power_supply has been
registered and has to be freed before the power_supply is unregistered,
otherwise it is possible that the irq fires while the power_supply is not
initialized yet or has already been freed.

While we are at it replace request_irq with request_any_context_irq.

bac43b2050 isp1704_charger: Detect HUB/Host chargers
To avoid breaking high speed chirp handshaking with CDP
chargers, no more then 500mA should be drawn. To make sure
of this, utilizing current_max property. After the device
has enumerated, it's safe to draw the maximum 1800mA as
defined in the Battery Charging Specification. This can be
also used with normal USB connection if the controller sends
ENUMERATED notification with the milliamps as data.

From now on the online property indicates VBUS, present
property if there is a charger and current_max the milliamps
possible to draw from VBUS.

86af95039b ds2760_battery: Fix calculation of time_to_empty_now
A check against division by zero was modified in commit b0525b48.
Since this change time_to_empty_now is always reported as zero
while the battery is discharging and as a negative value while
the battery is charging. This is because current is negative while
the battery is discharging.

Fix the check introduced by commit b0525b48 so that time_to_empty_now
is reported correctly during discharge and as zero while charging.
