* power: supply: sc27xx: Save last battery capacityYuanjiang Yu2018-12-061-1/+134
| | | | | | | | | | | Our charger manager can optimize the battery capacity periodically, so we can save last battery capacity into registers. Then next system power-on, we can read the last saved battery capacity as the initial battery capacity, which can make the battery capacity more accurate.
