2011-04-07power: ab8500_bm: Removal of maintenance chargingKalle Komierowski
This patch makes it possible to remove the maintenance A and B charging states and replaces them with a state that restarts the charging when the battery voltage level dropped below a certain level. The maintenance charging can now be turned of by setting a flag in the board configuration.

Four drivers has been developed: ab8500_charger: driver for controlling the AC and USB charger blocks in the AB8500 ab8500_btemp: in charge of identifying the battery and measuring the battery temperature. ab8500_fg: driver for calculating remaining capacity as well as providing the charging algorithm with battery data. ab8500_chargalg: the charging algorithm is implemented here.

2010-12-20[ANDROID] ab8500_bm: Always kick watchdog to avoid power off in ABB rev1.1Johan Palsson
There is a bug in rev1.1 of AB8500 which means that we have to continously kick the charger watchdog every 60 seconds or else it will power off. This error only occurs when you connect and then disconnect the DCIO charger. The solution is to wake up periodically on the FG IRQ and kick the charger watchdog. This is only done for ABB rev1.1 and when the DCIO charger has been enabled. We also take a wakelock when a DCIO charger is connected to be able to control algorithm execution. This is a battery safety issue. Also small changes is introduced to allow USB charging with ABB rev 1.1.
