Merge tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFS updates from Samuel Ortiz:
 "This is the MFD pull request for the 3.9 merge window.

  No new drivers this time, but a bunch of fairly big cleanups:

   - Roger Quadros worked on a OMAP USBHS and TLL platform data
     consolidation, OMAP5 support and clock management code cleanup.

   - The first step of a major sync for the ab8500 driver from Lee
     Jones.  In particular, the debugfs and the sysct interfaces got
     extended and improved.

   - Peter Ujfalusi sent a nice patchset for cleaning and fixing the
     twl-core driver, with a much needed module id lookup code
     improvement.

   - The regular wm5102 and arizona cleanups and fixes from Mark Brown.

   - Laxman Dewangan extended the palmas APIs in order to implement the
     palmas GPIO and rt drivers.

   - Laxman also added DT support for the tps65090 driver.

   - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra
     and Darren Hart.

   - Linus Walleij patchset for the ab8500 driver allowed ab8500 and
     ab9540 based devices to switch to the new abx500 pin-ctrl driver.

   - The max8925 now has device tree and irqdomain support thanks to
     Qing Xu.

   - The recently added rtsx driver got a few cleanups and fixes for a
     better card detection code path and now also supports the RTS5227
     chipset, thanks to Wei Wang and Roger Tseng."

+- reg: I2C slave address
+- interrupts: the interrupt outputs of the controller
+- regulators: A node that houses a sub-node for each regulator within the
