Merge tag 'irqchip-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip/genirq updates from Marc Zyngier: * Core code update: - Non-SMP IRQ affinity fixes, allowing UP kernel to behave similarly to SMP ones for the purpose of interrupt affinity - Let irq_set_chip_handler_name_locked() take a const struct irq_chip * - Tidy-up the NOMAP irqdomain API variant - Teach action_show() to use for_each_action_of_desc() - Make irq_chip_request_resources_parent() allow the parent callback to be optional - Remove dynamic allocations from populate_parent_alloc_arg() * New drivers: - Merge the long awaited IRQ support for the LoongArch architecture, with the provisional ACPICA update (to be reverted once the official support lands) - New Renesas RZ/G2L IRQC driver, equipped with its companion GPIO driver * Driver updates - Optimise the hot path operations for the SiFive PLIC, trading the locking for per-CPU priority masking masking operations which are apparently faster - Work around broken PLIC implementations that deal pretty badly with edge-triggered interrupts. Flag two implementations as affected. - Simplify the irq-stm32-exti driver, particularly the table that remaps the interrupts from exti to the GIC, reducing the memory usage - Convert the ocelot irq_chip to being immutable - Check ioremap() return value in the MIPS GIC driver - Move MMP driver init function declarations into the common .h - The obligatory typo fixes Link: https://lore.kernel.org/all/20220727192356.1860546-1-maz@kernel.org
