2013-03-18test_power: Fix a bug in setting module parameter valuesAndrey Gelman
When the kernel loads a module, module params are processed prior to calling module_init. As a result, setting module param value should not have side effects, at least as long as the module has not been initialized.

2013-03-18power_supply: Add support for tps65090-chargerRhyland Klein
This patch adds support for the tps65090 charger driver. This driver is responsible for controlling the charger aspect of the tps65090 mfd. Currently, this mainly consists of turning on and off the charger, but some features of the charger can be supported through this driver including: - Enable Auto Recharge based on Battery voltage - Fast Charge Safety Timer - Maximum battery discharge current - Maximum battery adapter current - Enable External Charge - Disable charging termination based on low charger current (supported) Once the driver is accepted, later patches can add support for the features above which are not yet supported.

2013-03-07ab8500-chargalg: Use hrtimerLee Jones
Timers used for charging safety and maintenance must work even when CPU power has collapsed. By using hrtimers with the realtime clock the system is able to trigger an alarm that wakes-up the CPU and makes it possible to handle events. Allow a little slack time of 5 minutes for the hrtimers to allow CPU to be woken-up in a more optimal power saving way. A 5 minute delay to time-out timers relative to hours does not impact on safety. Signed-off-by: Lee Jones <lee.jones@linaro.org>
