Merge tag 'drivers2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: More SoC driver updates" from Olof Johansson:
 "This branch contains a handful of driver updates, mostly to the
  LPC32xx platform but also for Samsung EXYNOS and Davinci.

  It had a few context conflicts against patches already merged through
  fixes-non-critical.  We should have resolved this early during the
  development cycle by pulling them in as a dependency, instead I did it
  after the fact this time."
