Up to now, power supply subsystem assumes that battery's charartric data is static and also often left as fuelgauge's role. However, fuelgauge driver or any power_supply driver can be worked with different battery with different implementation and battery also can be changed even in runtime. If so, it needs to notify its change to all related power_supply drivers not let them notice all with private way. Thus, it tries to introduce generic interface for management of the battery specification. In addition to, for the smart battery, this'll help to abstract battery interface which can be varied with different batteries. (SDQ, MIPI BIF..)
