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!
