Merge tag 'irq-core-2020-12-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "Generic interrupt and irqchips subsystem updates. Unusually, there is not a single completely new irq chip driver, just new DT bindings and extensions of existing drivers to accomodate new variants! Core: - Consolidation and robustness changes for irq time accounting - Cleanup and consolidation of irq stats - Remove the fasteoi IPI flow which has been proved useless - Provide an interface for converting legacy interrupt mechanism into irqdomains Drivers: - Preliminary support for managed interrupts on platform devices - Correctly identify allocation of MSIs proxyied by another device - Generalise the Ocelot support to new SoCs - Improve GICv4.1 vcpu entry, matching the corresponding KVM optimisation - Work around spurious interrupts on Qualcomm PDC - Random fixes and cleanups" * tag 'irq-core-2020-12-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (54 commits) irqchip/qcom-pdc: Fix phantom irq when changing between rising/falling driver core: platform: Add devm_platform_get_irqs_affinity() ACPI: Drop acpi_dev_irqresource_disabled() resource: Add irqresource_disabled() genirq/affinity: Add irq_update_affinity_desc() irqchip/gic-v3-its: Flag device allocation as proxied if behind a PCI bridge irqchip/gic-v3-its: Tag ITS device as shared if allocating for a proxy device platform-msi: Track shared domain allocation irqchip/ti-sci-intr: Fix freeing of irqs irqchip/ti-sci-inta: Fix printing of inta id on probe success drivers/irqchip: Remove EZChip NPS interrupt controller Revert "genirq: Add fasteoi IPI flow" irqchip/hip04: Make IPIs use handle_percpu_devid_irq() irqchip/bcm2836: Make IPIs use handle_percpu_devid_irq() irqchip/armada-370-xp: Make IPIs use handle_percpu_devid_irq() irqchip/gic, gic-v3: Make SGIs use handle_percpu_devid_irq() irqchip/ocelot: Add support for Jaguar2 platforms irqchip/ocelot: Add support for Serval platforms irqchip/ocelot: Add support for Luton platforms irqchip/ocelot: prepare to support more SoC ...
