Merge tag 'dt-for-3.7' of git://sources.calxeda.com/kernel/linux

Pull devicetree updates from Rob Herring:
 - Import of latest upstream device tree compiler (dtc)
 - New function of_get_child_by_name
 - Support for #size-cells of 0 and #addr-cells of >2
 - Couple of DT binding documentation updates

Fix up trivial conflicts due to of_get_child_by_name() having been added
next to the new of_get_next_available_child().
