Merge tag 'irqchip-core-4.1-3' of git://git.infradead.org/users/jcooper/linux into irq/core
irqchip core change for v4.1 (round 3) from Jason Cooper Purge the gic_arch_extn hacks and abuse by using the new stacked domains NOTE: Due to the nature of these changes, patches crossing subsystems have been kept together in their own branches. - tegra - Handle the LIC properly - omap - Convert crossbar to stacked domains - kill arm,routable-irqs in GIC binding - exynos - Convert PMU wakeup to stacked domains - shmobile, ux500, zynq (irq_set_wake branch) - Switch from abusing gic_arch_extn to using gic_set_irqchip_flags
