Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 "MFD bits for the 3.7 merge window.

  As usual we have a few new drivers:

   - TI LP8788
   - TI OMAP USB TLL
   - Maxim MAX8907
   - SMSC ECE1099
   - Dialog Semiconductor DA9055
   - A simpler syscon driver that allow us to get rid of the anatop one.

  Drivers are also gradually getting Device Tree and IRQ domain support.

  The following drivers got DT support:
   - palmas, 88pm860x, tc3589x and twl4030-audio

  And those ones now use the IRQ domain APIs:
   - 88pm860x, tc3589x, db8500_prcmu

  Also some other interesting changes:
   - Intel's ICH LPC now supports Lynx Point
   - TI's twl4030-audio added a GPO child
   - tps6527 enabled its backlight subdevice
   - The twl6030 pwm driver moved to the new PWM subsystem

  And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
  palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."

Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.

Guys, DON'T REBASE!
