Merge tag 'irqchip-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip updates from Marc Zyngier:

 - Add infrastructure to allow DT irqchip platform drivers to
   be built as modules
 - Allow qcom-pdc, mtk-cirq and mtk-sysirq to be built as module
 - Fix ACPI probing to avoid abusing function pointer casting
 - Allow bcm7120-l2 and brcmstb-l2 to be used as wake-up sources
 - Teach NXP's IMX INTMUX some power management
 - Allow stm32-exti to be used as a hierarchical irqchip
 - Let stm32-exti use the hw spinlock API in its full glory
 - A couple of GICv4.1 fixes
 - Tons of cleanups (mtk-sysirq, aic5, bcm7038-l1, imx-intmux,
   brcmstb-l2, ativic32, ti-sci-inta, lonsoon, MIPS GIC, GICv3)
