Merge tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD update from Samuel Ortiz:
 "For the 3.11 merge we only have one new MFD driver for the Kontron
  PLD.

  But we also have:
   - Support for the TPS659038 PMIC from the palmas driver.
   - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich
     driver.
   - RTL8411B support from the rtsx driver.
   - More DT support for the Arizona, max8998, twl4030-power and the
     ti_am335x_tsadc drivers.
   - The SSBI driver move under MFD.
   - A conversion to the devm_* API for most of the MFD drivers.
   - The twl4030-power got split from twl-core into its own module.
   - A major ti_am335x_adc cleanup, leading to a proper DT support.
   - Our regular arizona and wm* updates and cleanups from the Wolfson
     folks.
   - A better error handling and initialization, and a regulator
     subdevice addition for the 88pm80x driver.
   - A bulk platform_set_drvdata() call removal that's no longer need
     since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when
     no driver is bound")
