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."
