2012-08-15power: tps80031: charger: handle re-charge eventXin Xie
After the charging completed, TPS80031 can re-enable the charging if it sense the voltage dropping (120mV below target). Current drive does not handle this event and causing the charging forever stopped. This patch will check the above re-charging happens in the charging WDT handler, and will ack WDT in order to continue charging.

2012-08-13power: smb349: correct charger statusAllen Yu
When tegra-otg suspends with charger cable connected, the charger state and type should not be changed, neither should the charger callback be executed. SMB349 has a debounce delay of ~20ms +/- 3 after cable is unpluged and will stop all I2C functions for 2.3ms when getting reset to POR. Add 50ms' delay before reading charger status to avoid I2C error and make sure we get the right charger state.
