Merge tag 'mfd-3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD updates from Samuel Ortiz:
 "For the 3.13 merge window we have a couple of new drivers for the AMS
  AS3722 PMIC and for STMicroelectronics STw481x PMIC.

  Although this is a smaller update than usual, we also have:

   - Device tree support for the max77693 driver

   - linux/of.h inclusion for all DT compatible MFD drivers, to avoid
     build breakage in the future

   - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver

   - A small arizona update for new wm5110 DSP registers and a few fixes

   - A small palmas update as well, including an of_device table
     addition and a few minor fixes

   - Two small mfd-core changes, one including a memory leak fix for
     when mfd_add_device() fails

   - Our usual round of minor cleanups and janitorial fixes"
