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 interrupt department provides: Core updates: - Better spreading to NUMA nodes in the affinity management - Support for more than one set of interrupts to spread out to allow separate queues for separate functionality of a single device. - Decouple the non queue interrupts from being managed. Those are usually general interrupts for error handling etc. and those should never be shut down. This also a preparation to utilize the spreading mechanism for initial spreading of non-managed interrupts later. - Make the single CPU target selection in the matrix allocator more balanced so interrupts won't accumulate on single CPUs in certain situations. - A large spell checking patch so we don't end up fixing single typos over and over. Driver updates: - A bunch of new irqchip drivers (RDA8810PL, Madera, imx-irqsteer) - Updates for the 8MQ, F1C100s platform drivers - A number of SPDX cleanups - A workaround for a very broken GICv3 implementation on msm8996 which sports a botched register set. - A platform-msi fix to prevent memory leakage - Various cleanups" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) genirq/affinity: Add is_managed to struct irq_affinity_desc genirq/core: Introduce struct irq_affinity_desc genirq/affinity: Remove excess indentation irqchip/stm32: protect configuration registers with hwspinlock dt-bindings: interrupt-controller: stm32: Document hwlock properties irqchip: Add driver for imx-irqsteer controller dt-bindings/irq: Add binding for Freescale IRQSTEER multiplexer irqchip: Add driver for Cirrus Logic Madera codecs genirq: Fix various typos in comments irqchip/irq-imx-gpcv2: Add IRQCHIP_DECLARE for i.MX8MQ compatible irqchip/irq-rda-intc: Fix return value check in rda8810_intc_init() irqchip/irq-imx-gpcv2: Silence "fall through" warning irqchip/gic-v3: Add quirk for msm8996 broken registers irqchip/gic: Add support to device tree based quirks dt-bindings/gic-v3: Add msm8996 compatible string irqchip/sun4i: Add support for Allwinner ARMv5 F1C100s irqchip/sun4i: Move IC specific register offsets to struct irqchip/sun4i: Add a struct to hold global variables dt-bindings: interrupt-controller: Add suniv interrupt-controller irqchip: Add RDA8810PL interrupt driver ...
