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

Pull ARM SoC fixes from Olof Johansson:
 "A handful of fixes. I've been queuing them up a bit too long so the
  list is longer than it otherwise would have been spread out across a
  few -rcs.

  In general, it's a scattering of fixes across several platforms,
  nothing truly serious enough to point out.

  There's a slightly larger batch of them for the Davinci platforms due
  to work to bring them back to life after some time, so there's a
  handful of regressions, some of them going back very far, others more
  recent.

  There's also a few patches fixing DT on Renesas platforms since they
  changed some bindings without remaining backwards compatible,
  splitting up describing LVDS as a proper bridge instead of having it
  as part of the display unit.

  We could push for them to be backwards compatible with old device
  trees, but it's likely to regress eventually if nobody's actually
  using said compatibility"
