Merge tag 'irq-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt handling updates from Thomas Gleixner: "Core code: - Make the managed interrupts more robust by shutting them down in the core code when the assigned affinity mask does not contain online CPUs. - Make the irq simulator chip work on RT - A small set of cpumask and power manageent cleanups Drivers: - A set of changes which mark GPIO interrupt chips immutable to prevent the GPIO subsystem from modifying it under the hood. This provides the necessary infrastructure and converts a set of GPIO and pinctrl drivers over. - A set of changes to make the pseudo-NMI handling for GICv3 more robust: a missing barrier and consistent handling of the priority mask. - Another set of GICv3 improvements and fixes, but nothing outstanding - The usual set of improvements and cleanups all over the place - No new irqchip drivers and not even a new device tree binding! 100+ interrupt chips are truly enough" * tag 'irq-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits) irqchip: Add Kconfig symbols for sunxi drivers irqchip/gic-v3: Fix priority mask handling irqchip/gic-v3: Refactor ISB + EOIR at ack time irqchip/gic-v3: Ensure pseudo-NMIs have an ISB between ack and handling genirq/irq_sim: Make the irq_work always run in hard irq context irqchip/armada-370-xp: Do not touch Performance Counter Overflow on A375, A38x, A39x irqchip/gic: Improved warning about incorrect type irqchip/csky: Return true/false (not 1/0) from bool functions irqchip/imx-irqsteer: Add runtime PM support irqchip/imx-irqsteer: Constify irq_chip struct irqchip/armada-370-xp: Enable MSI affinity configuration irqchip/aspeed-scu-ic: Fix irq_of_parse_and_map() return value irqchip/aspeed-i2c-ic: Fix irq_of_parse_and_map() return value irqchip/sun6i-r: Use NULL for chip_data irqchip/xtensa-mx: Fix initial IRQ affinity in non-SMP setup irqchip/exiu: Fix acknowledgment of edge triggered interrupts irqchip/gic-v3: Claim iomem resources dt-bindings: interrupt-controller: arm,gic-v3: Make the v2 compat requirements explicit irqchip/gic-v3: Relax polling of GIC{R,D}_CTLR.RWP irqchip/gic-v3: Detect LPI invalidation MMIO registers ...
