Merge tag 'mfd-3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD (multi-function device) updates from Samuel Ortiz:
 "For the 3.12 merge window we have one new driver for the DA9063 PMIC
  from Dialog Semiconductor.

  Besides that driver we also have:

   - Device tree support for the s2mps11 driver

   - More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
     wl1273 and pcf50633-adc drivers.

   - A conversion to threaded IRQ and IRQ domain for the twl6030 driver.

   - A fairly big update for the rtsx driver: Better power saving
     support, better vendor settings handling, and a few fixes.

   - Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
     Kontron driver.

   - A conversion to the dev_get_platdata() API for all MFD drivers.

   - A removal of non-DT (legacy) support for the twl6040 driver.

   - A few fixes and additions (Mic detect level) to the wm5110 register
     tables.

   - Regmap support for the davinci_voicecodec driver.

   - The usual bunch of minor cleanups and janitorial fixes"
