X-Power AXP288 PMIC Fuel Gauge Driver

2015-03-07T19:08:58+00:00

New power_supply driver at driver/power which interfaces with the
axp20x mfd driver as a cell. Provides battery info, monitors for
changes, and generates alerts on temperature and capacity issues

Add LTC2941/LTC2943 Battery Gauge Driver

2015-01-22T02:23:07+00:00

Both the LTC2941 and LTC2943 measure battery capacity.
The LTC2943 is compatible with the LTC2941, it adds voltage and
temperature monitoring, and uses a slightly different conversion
formula for the charge counter.

To avoid confusion with e.g. the LTC2945, the driver is called
LTC2941 instead of LTC294X.

v2: Fix units of measurement: uV, uA and centidegrees.
v3: Correctly set configuration register. Allow negative values
    for the sense resistor.
v4: Run checkpatch.pl and fix all errors and warnings.
v5: Prefix "lltc," to devicetree properties.

power: charger-manager: Use alarmtimer for battery monitoring in suspend.

2015-01-21T19:52:07+00:00

To guerantee proper charing and managing batteries even in suspend,
charger-manager has used rtc device with rtc framework interface.
However, it is better to use alarmtimer for cleaner and more appropriate
operation.
This patch makes driver to use alarmtimer for polling work in suspend and
removes all deprecated codes related with using rtc interface.

power: max14577: Remove SYSFS dependency from Kconfig

2015-01-21T18:36:57+00:00

This is only a small clean-up. The driver can be built without SYSFS
as there exist stubs for used functions.

power: max77693: Add charger driver for Maxim 77693

2015-01-20T13:04:12+00:00

Add new driver for Maxim 77693 switch-mode charger (part of max77693
MFD driver) providing power supply class information to userspace.

The charger has +20V tolerant input. Current input can be set from 0 to
2.58 A. The charger can deliver up to 2.1 A to the battery or 3.5 A to
the system (when supplying additional current from battery to system).

The driver is configured through DTS (battery and system related
settings) and sysfs entries (timers and top-off charging threshold).

power: rt5033_battery: Add RT5033 Fuel gauge device driver

2015-01-20T12:58:31+00:00

This patch adds device driver of Richtek PMIC.
The driver support battery fuel gauge. Fuel gauge calculates and determines the
battery state of charge (SOC) according to battery open circuit voltage (OCV).
Also, this driver provides battery average voltage, voltage and battery present
property.

power: max14577: Fix circular config SYSFS dependency

2014-09-25T14:05:50+00:00

Make the max14577 charger driver depending on SYSFS instead selecting
it. This fixes warning on x86_64 with allmodconfig:

charger: max14577: Configure battery-dependent settings from DTS and sysfs

2014-09-24T14:25:49+00:00

Remove hard-coded values for:
 - Fast Charge current,
 - End Of Charge current,
 - Fast Charge timer,
 - Overvoltage Protection Threshold,
 - Battery Constant Voltage,
and use DTS or sysfs to configure them. This allows using the max14577 charger
driver with different batteries.

Now the charger driver requires valid configuration data from DTS. In
case of wrong configuration data it fails during probe.

The fast charge timer is configured through sysfs entry.

charger: max14577: Add support for MAX77836 charger

2014-09-24T14:25:44+00:00

Add support for MAX77836 charger to the max14577 driver. The MAX77836
charger is almost the same as 14577 model except:
 - No dead-battery detection;
 - Support for special charger (like in MAX77693);
 - Support for DX over-voltage protection (like in MAX77693);
 - Lower values of charging current (two times lower current for
   slow/fast charge, much lower EOC current);
 - Slightly different values in ChgTyp field of STATUS2 register. On
   MAX14577 0x6 is reserved and 0x7 dead battery. On the MAX77836 the
   0x6 means special charger and 0x7 is reserved. Regardless of these
   differences the driver maps them to one enum max14577_muic_charger_type.
