Pull a huge ab8500/pm2301 pile of changes from Lee Jones. Lee did an
awesome job cleaning this stuff up and thus brought ab8500 Stericsson's
development tree much closer to the mainline. Even more changes to come,
though.
Conflicts:
drivers/power/Kconfig
Power supply subsystem creates thermal zone device for the property
'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready
before 'ab8500 battery temperature monitor' driver is initialized. ab8500
btemp driver is initialized with subsys_initcall whereas thermal subsystem
is initialized with fs_initcall which causes
thermal_zone_device_register(...) to crash since the required structure
'thermal_class' is not initialized yet:

If charging is started before USB enumeration of an Accessory
Charger Adapter has finished, the AB8500 will generate a
VBUS_ERROR. This in turn results in timeouts and delays the
enumeration with around 15 seconds. This patch delays the
charging and then ramps currents slowly to avoid VBUS errors.
The delay allows the enumeration to have finished before
charging is turned on.

Today the battery recharge is determined with a voltage threshold. This
voltage threshold is only valid when the battery is relaxed. In charging
algorithm the voltage read is the loaded battery voltage and no
compensation is done to get the relaxed voltage. When maintenance
charging is not selected, this makes the recharging condition to almost
immediately activate when there is a discharge present on the battery.
Depending on which vendor the battery comes from this behavior can wear
out the battery much faster than normal.
The fuelgauge driver is responsible to monitor the actual battery
capacity and is able to estimate the remaining capacity. It is better to
use the remaining capacity as a limit to determine when battery should
be recharged.
