Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "The irq department delivers: - new core infrastructure to allow better management of multi-queue devices (interrupt spreading, node aware descriptor allocation ...) - a new interrupt flow handler to support the new fangled Intel VMD devices. - yet another new interrupt controller driver. - a series of fixes which addresses sparse warnings, missing includes, missing static declarations etc from Ben Dooks. - a fix for the error handling in the hierarchical domain allocation code. - the usual pile of small updates to core and driver code" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (46 commits) genirq: Fix missing irq allocation affinity hint irqdomain: Fix irq_domain_alloc_irqs_recursive() error handling irq/Documentation: Correct result of echnoing 5 to smp_affinity MAINTAINERS: Remove Jiang Liu from irq domains genirq/msi: Fix broken debug output genirq: Add a helper to spread an affinity mask for MSI/MSI-X vectors genirq/msi: Make use of affinity aware allocations genirq: Use affinity hint in irqdesc allocation genirq: Add affinity hint to irq allocation genirq: Introduce IRQD_AFFINITY_MANAGED flag genirq/msi: Remove unused MSI_FLAG_IDENTITY_MAP irqchip/s3c24xx: Fixup IO accessors for big endian irqchip/exynos-combiner: Fix usage of __raw IO irqdomain: Fix disposal of mappings for interrupt hierarchies irqchip/aspeed-vic: Add irq controller for Aspeed doc/devicetree: Add Aspeed VIC bindings x86/PCI/VMD: Use untracked irq handler genirq: Add untracked irq handler irqchip/mips-gic: Populate irq_domain names irqchip/gicv3-its: Implement two-level(indirect) device table support ...

+Aspeed Vectored Interrupt Controller
+
+These bindings are for the Aspeed AST2400 interrupt controller register layout.
+The SoC has an legacy register layout, but this driver does not support that
+mode of operation.
+
+Required properties:
+
+- compatible : should be "aspeed,ast2400-vic".
+
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 1.
+
+Example:
+
+ vic: interrupt-controller@1e6c0080 {
+ compatible = "aspeed,ast2400-vic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x1e6c0080 0x80>;
+ };
