Merge branch 'for-next' of git://gitorious.org/kernel-hsi/kernel-hsi

Pull HSI (High Speed Synchronous Serial Interface) framework from Carlos Chinea:
 "The High Speed Synchronous Serial Interface (HSI) is a serial
  interface mainly used for connecting application engines (APE) with
  cellular modem engines (CMT) in cellular handsets.

  The framework is currently being used for some people and we would
  like to see it integrated into the kernel for 3.3.  There is no HW
  controller drivers in this pull, but some people have already some of
  them pending which they would like to push as soon as this integrated.
  I am also working on the acceptance for an TI OMAP one, based on a
  compatible legacy version of the interface called SSI."

Ok, so it didn't get into 3.3, but here it is pulled into 3.4.

Several people piped up to say "yeah, we want this".
