Merge tag 'devicetree-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:
 "A fairly large (by DT standards) pull request this time with the
  majority being some overdue moving DT binding docs around to
  consolidate similar bindings.

   - DT binding doc consolidation moving similar bindings to common
     locations.  The majority of these are display related which were
     scattered in video/, fb/, drm/, gpu/, and panel/ directories.

   - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all
     dtbs in the tree for most arches with dts files (except powerpc for
     now).

   - OF_IRQ=n fixes for user enabled CONFIG_OF.

   - of_node_put ref counting fixes from Julia Lawall.

   - Common DT binding for wakeup-source and deprecation of all similar
     bindings.

   - DT binding for PXA LCD controller.

   - Allow ignoring failed PCI resource translations in order to ignore
     64-bit addresses on non-LPAE 32-bit kernels.

   - Support setting the NUMA node from DT instead of only from parent
     device.

   - Couple of earlycon DT parsing fixes for address and options"
