Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux

Pull embedded i2c changes from Wolfram Sang:
 "Changes for the "embedded" part of the I2C subsystem:

   - lots of devicetree conversions of drivers (and preparations for
     that)
   - big cleanups for drivers for OMAP, Tegra, Nomadik, Blackfin
   - Rafael's struct dev_pm_ops conversion patches for I2C
   - usual driver cleanups and fixes

  All patches have been in linux-next for an apropriate time and all
  patches touching files outside of i2c-folders should have proper acks
  from the maintainers."

* 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (60 commits)
