Merge tag 'boards-3.12-2' of git://git.infradead.org/linux-mvebu into next/boards
From Jason Cooper, mvebu boards changes for v3.12:
- kirkwood
- convert Dockstar, Guruplug, mv88f6281gtw_ge to DT
- remove legacy boards (which have DT support) sheevaplug, lacie boards
- ARRAY_AND_SIZE() cleanup
- dove
- some DT node updates (depends on irqchip/clocksource DT changes earlier)
- add the D2Plug board
* tag 'boards-3.12-2' of git://git.infradead.org/linux-mvebu:
ARM: dove: add initial DT file for Globalscale D2Plug
ARM: dove: add GPIO IR receiver node to SolidRun CuBox
ARM: dove: add common pinmux functions to DT
ARM: dove: add cpu device tree node
arch/arm/mach-kirkwood: Avoid using ARRAY_AND_SIZE(e) as a function argument
ARM: kirkwood: fix DT building and update defconfig
ARM: kirkwood: Remove all remaining trace of DNS-320/325 platform code
ARM: kirkwood: use dts pre-processor for mv88f6281gtw-ge
ARM: kirkwood: convert the mv88f6281gtw_ge board to DT
ARM: kirkwood: remove LaCie boards that are supported through DT
ARM: kirkwood: remove support for legacy booting of Sheevaplug
ARM: kirkwood: remove support for legacy booting of Guruplug
ARM: kirkwood: remove support for legacy booting of Dockstar

- This option enables build of the LED TPU platform driver,
