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.
