Merge tag 'for-v3.9' of git://git.infradead.org/battery-2.6

Pull battery updates from Anton Vorontsov:
 "Four new drivers:

   - goldfish_battery:

     This is Android Emulator battery driver.  Originally from Google,
     but Intel folks reshaped it for mainline

   - pm2301_charger:

     A new driver for ST-Ericsson 2301 Power Management chip, uses
     AB8500 battery management core

   - qnap-poweroff:

     The driver adds poweroff functionality for QNAP NAS boxes

   - restart-poweroff:

     A generic driver that implements 'power off by restarting'.  The
     actual poweroff functionality is implemented through a bootloader,
     so Linux' task is just to restart the box.  The driver is useful on
     Buffalo Linkstation LS-XHL and LS-CHLv2 boards.  Andrew Lunn worked
     on submitting the driver (as well as qnap-poweroff above).

  Additionally:

   - A lot of fixes for ab8500 drivers.  This is a part of efforts of
     syncing internal ST-Ericsson development tree with the mainline.
     Lee Jones @ Linaro worked on compilation and reshaping these
     series.

   - New health properties for the power supplies: "Watchdog timer
     expire" and "Safety timer expire"

   - As usual, a bunch of fixes/cleanups here and there"

  bq2415x_charger: Add support for offline and 100mA mode
  generic-adc-battery: Fix forever loop in gab_remove()
  goldfish_battery: Add missing GENERIC_HARDIRQS dependency
  da9030_battery: Include notifier.h
  bq27x00_battery: Fix reporting battery temperature
  power/reset: Remove newly introduced __dev* annotations
  lp8727_charger: Small cleanup in naming
  ab8500_btemp: Demote initcall sequence
  ds2782_battery: Add power_supply_changed() calls for proper uevent support
  power: Add battery driver for goldfish emulator
  u8500-charger: Delay for USB enumeration
  ab8500-bm: Remove individual [charger|btemp|fg|chargalg] pdata structures
  ab8500-charger: Do not touch VBUSOVV bits
  ab8500-fg: Use correct battery charge full design
  pm2301: LPN mode control support
  pm2301: Enable vbat low monitoring
  ab8500-bm: Flush all work queues before suspending
  ab8500-fg: Go to INIT_RECOVERY when charger removed
  ab8500-charger: Add support for autopower on AB8505 and AB9540
  abx500-chargalg: Add new sysfs interface to get current charge status
  ...

Fix up fairly straightforward conflicts in the ab8500 driver.  But since
it seems to be ARM-specific, I can't even compile-test the result..
