Merge tag 'at91-cleanup-for-linus' of git://git./linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
 "On Atmel AT91, the conversion to device tree is now considered
  complete, and all machines that were not already converted in 3.18 are
  assumed to be unused and dropped by the maintainer.

  All remaining board files that were written in C are dropped, and the
  ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
  altogether.  Cleaning up the last pieces was great fun, so I took the
  time to do some of the coding myself and removed several hundred code
  lines that ended up unused after the board files were done.

  There are still a couple of AT91 specific device drivers that are not
  converted to DT (CF, USB-OTG) and currently not working, and the
  platform itself is not "multiplatform"-enabled, but both issues are
  going to be taken care of in the 3.20 cycle.

  This is split out from the other cleanups purely based on the size of
  the branch"
