Merge branch 'next/dt' of git://git.linaro.org/people/arnd/arm-soc
* 'next/dt' of git://git.linaro.org/people/arnd/arm-soc: ARM: gic: use module.h instead of export.h ARM: gic: fix irq_alloc_descs handling for sparse irq ARM: gic: add OF based initialization ARM: gic: add irq_domain support irq: support domains with non-zero hwirq base of/irq: introduce of_irq_init ARM: at91: add at91sam9g20 and Calao USB A9G20 DT support ARM: at91: dt: at91sam9g45 family and board device tree files arm/mx5: add device tree support for imx51 babbage arm/mx5: add device tree support for imx53 boards ARM: msm: Add devicetree support for msm8660-surf msm_serial: Add devicetree support msm_serial: Use relative resources for iomem Fix up conflicts in arch/arm/mach-at91/{at91sam9260.c,at91sam9g45.c}
