Merge tag 'irqchip-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip updates for 4.14 from Marc Zyngier: - irqchip-specific part of the monster GICv4 series - new UniPhier AIDET irqchip driver - new variants of some Freescale MSI widget - blanket removal of of_node->full_name in printk - random collection of fixes
