Merge branch 'dt-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
* 'dt-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
arm/dts: mt_ventoux: very basic support for TeeJet Mt.Ventoux board
ARM: OMAP2+: Remove extra ifdefs for board-generic
ARM: OMAP2+: Fix build error when only ARCH_OMAP2/3 or 4 is selected
ARM: OMAP2+: board-generic: Use of_irq_init API
arm/dts: OMAP3: Add interrupt-controller bindings for INTC
ARM: OMAP2/3: intc: Add DT support for TI interrupt controller
