Subject: [RFC PATCH 0/3] power: Generic interface to get battery specification.

This patches contains supporting generic interface to get battery specification
and of-based battery driver which use the interface.

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..)

Jonghwa Lee (3):
  power: core: Add generic interface to get battery specification.
  power: core: Add variables related temperature to power_supply_info.
  power: of_battery: Initial support for of-based battery specification
    driver.
