Merge tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/socHEADmaster

Pull ARM SoC platform updates from Arnd Bergmann:
 "The 32-bit Arm platforms are a bit more interesting this time: I
  refreshed an earlier series to mark code as deprecated that does have
  the tendency of getting in the way of cleanups and new features but
  has close to zero users. Among these are:

   - 22 of the remaining 28 legacy board files that predate the current
     devicetree based descriptions, using old chips from Intel and
     Marvell. The remaining six board files are for TI OMAP1 and Samsung
     s3c64xx chips and all still have known users.

   - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
     machines based on these. These all use devicetree but the CPU
     support causes disproportional work. Most of them are just
     reference boards, the notable exceptions being the Nokia N800/N810
     tablet and the Buglabs BUG platform.

   - be8, be32, oabi and iwmmxt userspace binaries, which were mostly
     associated with the platforms now scheduled for removal and are
     increasingly problematic to support with modern toolchains.

  Nothing is actually removed at this point, to ensure that any
  remaining users continue to have the 7.3-LTS for a while longer.
  Patches for removal are currently being tested.

  Other updates include a continued work to convert GPIO number based
  interfaces to descriptors, a patch to restore little-endian mode on
  the one Arm platform (ixp4xx) that only worked in big-endian mode
  recently, and some minor cleanups and bugfixes"
