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

Pull ARM SoC fixes from Olof Johansson:
 "Here's our last set of fixes for 3.17.  Most of these are for TI
  platforms, fixing some noisy Kconfig issues, runtime clock and power
  issues on several platforms and NAND timings on DRA7.

  There are also a couple of bug fixes for i.MX, one for QCOM and a
 small fix to avoid section mismatch noise on PXA.

  Diffstat looks large, partially due to some tables being updated and
  thus touching many lines.  The qcom gsbi change also restructures
  clock management a bit and thus touches a bunch of lines.

  All in all, a bit more changes than we'd like at this point, but
  nothing stands out as risky either so it seems like the right thing to
  send it up now instead of holding it to the merge window"
