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

Pull ARM SoC platform updates from Arnd Bergmann:
 "These are mostly minor bugfixes, cleanup and many defconfig updates to
  support added drivers. In particular OMAP and PXA keep cleaning up the
  legacy code base, as usual.

  Nvidia adds some more SoC support code for Tegra 186.

  For the first time on years, we are actually adding a non-DT platform
  for the EP93xx based Liebherr controller BK3.1. It's a minor variation
  of the EP93xx reference design and in active use, while EP93xx
  apparently doesn't have enough new development to have any device tree
  support"
