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

Pull ARM SoC non-urgent fixes from Arnd Bergmann:
 "As usual, we queue up a few fixes that don't seem urgent enough to go
  in through -rc, or that just came a little too late given their size.

  The zx fixes make the platform finally boot on real hardware, the
  davinci and imx31 get the DT support working better for some of the
  machines that are still normally used with classic board files. One
  tegra fix is important for new bootloader versions, but the bug has
  been around for a while without anyone noticing.

  The other changes are mostly cosmetic"
