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
