Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
   TI's TPS65090 and TPS65217.
 - New variants support (8420, 8520 ab9540), cleanups and bug fixes for
   the abx500 and db8500 ST-E chipsets.
 - Some minor fixes and update for the wm8994 from Mark.
 - The beginning of a long term TWL cleanup effort coming from the TI
   folks.
 - Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997
   drivers.

Fix up trivial conflicts due to duplicate patches and header file
cleanups (<linux/device.h> removal etc).
