Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Highlights:

   - OF and ACPI helpers are now included in the core, and not in
     external files anymore.  This removes dependency problems for
     modules and is cleaner, in general.
   - mv64xxx-driver gains fifo usage to support mv78230
   - imx-driver overhaul to support VF610
   - various cleanups, most notably related to devm_* and CONFIG_PM
     usage
   - driver bugfixes and smaller feature additions"
