Merge tag 'devicetree-for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull second batch of devicetree updates from Rob Herring:
 "As Grant mentioned in the first devicetree pull request, here is the
  2nd batch of DT changes for 4.1.  The main remaining item here is the
  endianness bindings and related 8250 driver support.

   - DT endianness specification bindings

   - big-endian 8250 serial support

   - DT overlay unittest updates

   - various DT doc updates

   - compile fixes for OF_IRQ=n"
