Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Arnd Bergmann:
 "This is a rather large set of bugfixes, as we just returned from the
  Christmas break. Most of these are relatively unimportant fixes for
  regressions introduced during the merge window, and about half of the
  changes are for mach-omap2.

  A couple of patches are just cleanups and dead code removal that I
  would not normally have considered for merging after -rc2, but I
  decided to take them along with the fixes this time.

  Notable fixes include:

   - removing the skeleton.dtsi include broke a number of machines, and
     we have to put empty /chosen nodes back to be able to pass kernel
     command lines as before

   - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as
     it had been for no good reason for a long time"
