Merge tag 'devicetree-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux into next
Pull DeviceTree updates from Rob Herring: - Another round of clean-up of FDT related code in architecture code. This removes knowledge of internal FDT details from most architectures except powerpc. - Conversion of kernel's custom FDT parsing code to use libfdt. - DT based initialization for generic serial earlycon. The introduction of generic serial earlycon support went in through the tty tree. - Improve the platform device naming for DT probed devices to ensure unique naming and use parent names instead of a global index. - Fix a race condition in of_update_property. - Unify the various linker section OF match tables and fix several function prototype errors. - Update platform_get_irq_byname to work in deferred probe cases. - 2 binding doc updates * tag 'devicetree-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (58 commits) of: handle NULL node in next_child iterators of/irq: provide more wrappers for !CONFIG_OF devicetree: bindings: Document micrel vendor prefix dt: bindings: dwc2: fix required value for the phy-names property of_pci_irq: kill useless variable in of_irq_parse_pci() of/irq: do irq resolution in platform_get_irq_byname() of: Add a testcase for of_find_node_by_path() of: Make of_find_node_by_path() handle /aliases of: Create unlocked version of for_each_child_of_node() lib: add glibc style strchrnul() variant of: Handle memory@0 node on PPC32 only pci/of: Remove dead code of: fix race between search and remove in of_update_property() of: Use NULL for pointers of: Stop naming platform_device using dcr address of: Ensure unique names without sacrificing determinism tty/serial: pl011: add DT based earlycon support of/fdt: add FDT serial scanning for earlycon of/fdt: add FDT address translation support serial: earlycon: add DT support ...
