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: remove obsolete SDIO clock gate workaround 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 ARM: kirkwood: add gigabit ethernet and mvmdio device tree nodes ARM: dove: add gigabit ethernet and mvmdio device tree nodes + Linux 3.11-rc2 Signed-off-by: Olof Johansson <olof@lixom.net>
