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 departement provides the usual mixed bag: Core: - Further improvements to the irq timings code which aims to predict the next interrupt for power state selection to achieve better latency/power balance - Add interrupt statistics to the core NMI handlers - The usual small fixes and cleanups Drivers: - Support for Renesas RZ/A1, Annapurna Labs FIC, Meson-G12A SoC and Amazon Gravition AMR/GIC interrupt controllers. - Rework of the Renesas INTC controller driver - ACPI support for Socionext SoCs - Enhancements to the CSKY interrupt controller - The usual small fixes and cleanups" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits) irq/irqdomain: Fix comment typo genirq: Update irq stats from NMI handlers irqchip/gic-pm: Remove PM_CLK dependency irqchip/al-fic: Introduce Amazon's Annapurna Labs Fabric Interrupt Controller Driver dt-bindings: interrupt-controller: Add Amazon's Annapurna Labs FIC softirq: Use __this_cpu_write() in takeover_tasklets() irqchip/mbigen: Stop printing kernel addresses irqchip/gic: Add dependency for ARM_GIC_MAX_NR genirq/affinity: Remove unused argument from [__]irq_build_affinity_masks() genirq/timings: Add selftest for next event computation genirq/timings: Add selftest for irqs circular buffer genirq/timings: Add selftest for circular array genirq/timings: Encapsulate storing function genirq/timings: Encapsulate timings push genirq/timings: Optimize the period detection speed genirq/timings: Fix timings buffer inspection genirq/timings: Fix next event index function irqchip/qcom: Use struct_size() in devm_kzalloc() irqchip/irq-csky-mpintc: Remove unnecessary loop in interrupt handler dt-bindings: interrupt-controller: Update csky mpintc ...
