Merge tag 'boards-3.12' of git://git.infradead.org/linux-mvebu into next/boards

From Jason Cooper:
mvebu boards changes for v3.12

 - convert kirkwood, dove, orion5x to DT init of mv643xx_eth
    - _lots_ of board code removal :)
 - convert kirkwood, dove and orion5x to DT init of clocksource and irqchip

* tag 'boards-3.12' of git://git.infradead.org/linux-mvebu:
  ARM: plat-orion: add reg offset to DT irq driver stub

  ARM: kirkwood: convert to DT irqchip and clocksource
  ARM: dove: convert to DT irqchip and clocksource
  ARM: orion5x: update intc device tree node to new reg layout
  ARM: kirkwood: move device tree nodes to DT irqchip and clocksource
  ARM: dove: move device tree nodes to DT irqchip and clocksource
  ARM: orion5x: remove legacy mv643xx_eth board setup
  ARM: kirkwood: remove legacy clk alias for mv643xx_eth
  ARM: kirkwood: remove redundant DT board files
  ARM: dove: remove legacy mv643xx_eth setup
  ARM: orion5x: add gigabit ethernet and mvmdio device tree nodes
