Merge tag 'mfd-3.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 "Besides the usual cleanups, this one brings:

   * Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton,
     ST-E's STAX211, Samsung's MAX77693 and TI's LM3533.

   * Device tree support for the twl6040, tps65910, da9502 and ab8500
     drivers.

   * Fairly big tps56910, ab8500 and db8500 updates.

   * i2c support for mc13xxx.

   * Our regular update for the wm8xxx driver from Mark."

Fix up various conflicts with other trees, largely due to ab5500 removal
etc.
