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

Pull embedded i2c update from Wolfram Sang:
 "This only contains one new driver which had multiple dependencies
  (pinctrl, i2c-mux-rework, new devm_* functions), so I decided to wait
  for rc1.  Plus, it had to wait a little for the ack of a devicetree
  maintainer since the bindings were not trivial enough for me to pass
  through.

  So, given that, I hope there is still something like the "new driver
  rule", so we could have the driver in 3.5 and people can start using
  it.  That would make merging support for some boards easier for 3.6
  since the dependency on this driver is gone then."
