Merge branch 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6
* 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6: mtd/m25p80: add support to parse the partitions by OF node of/irq: of_irq.c needs to include linux/irq.h of/mips: Cleanup some include directives/files. of/mips: Add device tree support to MIPS of/flattree: Eliminate need to provide early_init_dt_scan_chosen_arch of/device: Rework to use common platform_device_alloc() for allocating devices of/xsysace: Fix OF probing on little-endian systems of: use __be32 types for big-endian device tree data of/irq: remove references to NO_IRQ in drivers/of/platform.c of/promtree: add package-to-path support to pdt of/promtree: add of_pdt namespace to pdt code of/promtree: no longer call prom_ functions directly; use an ops structure of/promtree: make drivers/of/pdt.c no longer sparc-only sparc: break out some PROM device-tree building code out into drivers/of of/sparc: convert various prom_* functions to use phandle sparc: stop exporting openprom.h header powerpc, of_serial: Endianness issues setting up the serial ports of: MTD: Fix OF probing on little-endian systems of: GPIO: Fix OF probing on little-endian systems
