Merge branch 'next/cleanup2' of git://git.linaro.org/people/arnd/arm-soc
* 'next/cleanup2' of git://git.linaro.org/people/arnd/arm-soc: (31 commits) ARM: OMAP: Warn if omap_ioremap is called before SoC detection ARM: OMAP: Move set_globals initialization to happen in init_early ARM: OMAP: Map SRAM later on with ioremap_exec() ARM: OMAP: Remove calls to SRAM allocations for framebuffer ARM: OMAP: Avoid cpu_is_omapxxxx usage until map_io is done ARM: OMAP1: Use generic map_io, init_early and init_irq arm/dts: OMAP3+: Add mpu, dsp and iva nodes arm/dts: OMAP4: Add a main ocp entry bound to l3-noc driver ARM: OMAP2+: l3-noc: Add support for device-tree ARM: OMAP2+: board-generic: Add i2c static init ARM: OMAP2+: board-generic: Add DT support to generic board arm/dts: Add support for OMAP3 Beagle board arm/dts: Add initial device tree support for OMAP3 SoC arm/dts: Add support for OMAP4 SDP board arm/dts: Add support for OMAP4 PandaBoard arm/dts: Add initial device tree support for OMAP4 SoC ARM: OMAP: omap_device: Add a method to build an omap_device from a DT node ARM: OMAP: omap_device: Add omap_device_[alloc|delete] for DT integration of: Add helpers to get one string in multiple strings property ARM: OMAP2+: devices: Remove all omap_device_pm_latency structures ... Fix up trivial header file conflicts in arch/arm/mach-omap2/board-generic.c
