Rhyland Klein bb87910160 bq20z75: Add optional battery detect gpio
Adding support for an optional gpio for battery detection. This is
passed in through the i2c platform data. It also accepts another
field, battery_detect_present to signify the gpio state which means
the battery is present, either 0 (low) or 1 (high).

Lars-Peter Clausen 7fb7ba588c bq27x00: Add bq27000 support
This patch adds support for the bq27000 battery to the bq27x00 driver.
The bq27000 is similar to the bq27200 except that it uses the HDQ bus
instead of I2C to communicate with the host system.

The driver is implemented as a platform driver. The driver expects to be
provided with a read callback function through its platform data. The read
function is assumed to do the lowlevel HDQ handling and read out the value
of a certain register.

MyungJoo Ham 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.
