Merge tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFS update from Samuel Ortiz:
 "This is the MFD patch set for the 3.8 merge window.

  We have several new drivers, most of the time coming with their sub
  devices drivers:

   - Austria Microsystem's AS3711
   - Nano River's viperboard
   - TI's TPS80031, AM335x TS/ADC,
   - Realtek's MMC/memstick card reader
   - Nokia's retu

  We also got some notable cleanups and improvements:

   - tps6586x got converted to IRQ domains.
   - tps65910 and tps65090 moved to the regmap IRQ API.
   - STMPE is now Device Tree aware.
   - A general twl6040 and twl-core cleanup, with moves to the regmap
     I/O and IRQ APIs and a conversion to the recently added PWM
     framework.
   - sta2x11 gained regmap support.

  Then the rest is mostly tiny cleanups and fixes, among which we have
  Mark's wm5xxx and wm8xxx patchset."

Far amount of annoying but largely trivial conflicts.  Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.
