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."
