Merge branch 'i2c/for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Highlights:

   - new drivers for Mediatek I2C, APM X-Gene, Broadcom Settop
   - major updates to at91, davinci
   - bugfixes to the mux infrastructure when dealing with the new quirk
     mechanism
   - more users for the bus recovery feature
   - further improvements to the slave framework

  Plus the usual bunch of smaller driver and core improvements and
  fixes.

  There is one patch removing old code from an ARM platform.  This has
  been acked by the sh_mobile maintainer Simon Horman"
