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

Pull ARM SoC platform updates from Arnd Bergmann:
 "The main change this time around is a cleanup of some of the oldest
  platforms based on the XScale and ARM9 CPU cores, which are between 10
  and 20 years old.

  The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
  IOP33x/IOP13xx platforms are removed after we determined that nobody
  is using them any more.

  The TI Davinci and NXP LPC32xx platforms on the other hand are still
  in active use and are converted to the ARCH_MULTIPLATFORM build,
  meaning that we can compile a kernel that works on these along with
  most other ARMv5 platforms. Changes toward that goal are also merged
  for IOP32x, but additional work is needed to complete this. Patches
  for the remaining ARMv5 platforms have started but need more work and
  some testing.

  Support for the new ASpeed AST2600 gets added, this is based on the
  Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
  ARMv6 chips in the same family.

  Other changes include a cleanup of the ST-Ericsson ux500 platform and
  the move of the TI Davinci platform to a new clocksource driver"

[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
  buildable on other platforms through COMPILE_TEST, but that causes new
  warnings that I most definitely do not want to see during the merge
  window as that could hide other issues.

  So the COMPILE_TEST option got disabled for them again   - Linus ]
