Merge tag 'irqchip-fixes-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier: - More compatible strings for the Ingenic irqchip (introducing the JZ4760B SoC) - Select GENERIC_IRQ_MULTI_HANDLER on the ARM ep93xx platform - Drop all GENERIC_IRQ_MULTI_HANDLER selections from the irqchip Kconfig, now relying on the architecture to get it right - Drop the debugfs_file field from struct irq_domain, now that debugfs can track things on its own
