This patchset add new feature related to charging battery to complement necessary feature for charging. This patchset include following new feature for charging battery.
Explain implemented feature of this patchset: - Code clean on first and second patch. - Add support sysfs entry for charger(regulator) to control charger from user-space. If some development board use one more chargers(regulator) for charging but only need one charger on specific case which is dependent on user scenario or hardware restrictions, the user enter 1 or 0(zero) to "/sys/class/power_supply /battery/charger.[index]/externally_control". For example, if user enter 1 to "/sys/.../charger.[index]/externally_control", this charger isn't controlled from charger-manager and always stay off state of regulator. - Check fully charged state of battery periodically to prevent overcharging. - Limit maximum possible duration of charging to prevent overcharging, also check discharging duration to maintain fully charged state of battery and to prevent much drop voltage than given data through platform data of charger_desc.
Chanwoo Choi (5): charger-manager: Disable battery charging when charger cable is detached charger-manager: Use replacement variable to check state of battery charger-manager: Add support sysfs entry for charger charger-manager: Check fully charged state of battery periodically charger-manager: Support limit of maximum possible duration for charging/discharging
