Merge branch 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6
* 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6: (63 commits) of/platform: Register of_platform_drivers with an "of:" prefix of/address: Clean up function declarations of/spi: call of_register_spi_devices() from spi core code of: Provide default of_node_to_nid() implementation. of/device: Make of_device_make_bus_id() usable by other code. of/irq: Fix endian issues in parsing interrupt specifiers of: Fix phandle endian issues of/flattree: fix of_flat_dt_is_compatible() to match the full compatible string of: remove of_default_bus_ids of: make of_find_device_by_node generic microblaze: remove references to of_device and to_of_device sparc: remove references to of_device and to_of_device powerpc: remove references to of_device and to_of_device of/device: Replace of_device with platform_device in includes and core code of/device: Protect against binding of_platform_drivers to non-OF devices of: remove asm/of_device.h of: remove asm/of_platform.h of/platform: remove all of_bus_type and of_platform_bus_type references of: Merge of_platform_bus_type with platform_bus_type drivercore/of: Add OF style matching to platform bus ... Fix up trivial conflicts in arch/microblaze/kernel/Makefile due to just some obj-y removals by the devicetree branch, while the microblaze updates added a new file.
