Merge tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: "DeviceTree updates for 3.13. This is a bit larger pull request than usual for this cycle with lots of clean-up. - Cross arch clean-up and consolidation of early DT scanning code. - Clean-up and removal of arch prom.h headers. Makes arch specific prom.h optional on all but Sparc. - Addition of interrupts-extended property for devices connected to multiple interrupt controllers. - Refactoring of DT interrupt parsing code in preparation for deferred probe of interrupts. - ARM cpu and cpu topology bindings documentation. - Various DT vendor binding documentation updates" * tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (82 commits) powerpc: add missing explicit OF includes for ppc dt/irq: add empty of_irq_count for !OF_IRQ dt: disable self-tests for !OF_IRQ of: irq: Fix interrupt-map entry matching MIPS: Netlogic: replace early_init_devtree() call of: Add Panasonic Corporation vendor prefix of: Add Chunghwa Picture Tubes Ltd. vendor prefix of: Add AU Optronics Corporation vendor prefix of/irq: Fix potential buffer overflow of/irq: Fix bug in interrupt parsing refactor. of: set dma_mask to point to coherent_dma_mask of: add vendor prefix for PHYTEC Messtechnik GmbH DT: sort vendor-prefixes.txt of: Add vendor prefix for Cadence of: Add empty for_each_available_child_of_node() macro definition arm/versatile: Fix versatile irq specifications. of/irq: create interrupts-extended property microblaze/pci: Drop PowerPC-ism from irq parsing of/irq: Create of_irq_parse_and_map_pci() to consolidate arch code. of/irq: Use irq_of_parse_and_map() ...
