Merge tag 'for-v3.7' of git://git.infradead.org/battery-2.6

Pull battery updates from Anton Vorontsov:
 "1. New drivers:
     - Marvell 88pm860x charger and battery drivers;
     - Texas Instruments LP8788 charger driver;
  2. Two new power supply properties: whether a battery is authentic,
     and chargers' maximal currents and voltages;
  3. A lot of TI LP8727 Charger cleanups;
  4. New features for Charger Manager, mainly now we can disable
     specific regulators;
  5. Random fixes and cleanups for other drivers."

Fix up trivial conflicts in <linux/mfd/88pm860x.h>
