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 comes a bit later than I planned, and as a consequence is a
  larger than it should be.

  Most of the changes are devicetree fixes, across lots of platforms:
  Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic
  Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci.

  Also across many platforms, I applied an older series of simple
  randconfig build fixes. This includes making the CONFIG_MTD_XIP option
  compile again, which had been broken for many years and probably has
  not been missed, but it felt wrong to just remove it completely.

  The only other changes are:

   - We enable HWSPINLOCK in defconfig to get some Qualcomm boards to
     work out of the box.

   - A few regression fixes for Texas Instruments OMAP2+.

   - A boot regression fix for the Renesas regulator quirk.

   - A suspend/resume fix for Uniphier SoCs, fixing the resume of the
     system bus"
