Merge tag 'irq-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "Updates to the interrupt core and driver subsystems: Core changes: - The usual set of small fixes and improvements all over the place, but nothing stands out MSI changes: - Further consolidation of the PCI/MSI interrupt chip code - Make MSI sysfs code independent of PCI/MSI and expose the MSI interrupts of platform devices in the same way as PCI exposes them. Driver changes: - Support for ARM GICv3 EPPI partitions - Treewide conversion to generic_handle_domain_irq() for all chained interrupt controllers - Conversion to bitmap_zalloc() throughout the irq chip drivers - The usual set of small fixes and improvements" * tag 'irq-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (57 commits) platform-msi: Add ABI to show msi_irqs of platform devices genirq/msi: Move MSI sysfs handling from PCI to MSI core genirq/cpuhotplug: Demote debug printk to KERN_DEBUG irqchip/qcom-pdc: Trim unused levels of the interrupt hierarchy irqdomain: Export irq_domain_disconnect_hierarchy() irqchip/gic-v3: Fix priority comparison when non-secure priorities are used irqchip/apple-aic: Fix irq_disable from within irq handlers pinctrl/rockchip: drop the gpio related codes gpio/rockchip: drop irq_gc_lock/irq_gc_unlock for irq set type gpio/rockchip: support next version gpio controller gpio/rockchip: use struct rockchip_gpio_regs for gpio controller gpio/rockchip: add driver for rockchip gpio dt-bindings: gpio: change items restriction of clock for rockchip,gpio-bank pinctrl/rockchip: add pinctrl device to gpio bank struct pinctrl/rockchip: separate struct rockchip_pin_bank to a head file pinctrl/rockchip: always enable clock for gpio controller genirq: Fix kernel doc indentation EDAC/altera: Convert to generic_handle_domain_irq() powerpc: Bulk conversion to generic_handle_domain_irq() nios2: Bulk conversion to generic_handle_domain_irq() ...
