Merge tag 'irqchip-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip and irqdomain updates from Marc Zyngier:
New HW support:
- New driver for the Nuvoton WPCM450 interrupt controller
- New driver for the IDT 79rc3243x interrupt controller
- Add support for interrupt trigger configuration to the MStar irqchip
- Add more external interrupt support to the STM32 irqchip
- Add new compatible strings for QCOM SC7280 to the qcom-pdc binding
Fixes and cleanups:
- Drop irq_create_strict_mappings() and irq_create_identity_mapping()
from the irqdomain API, with cleanups in a couple of drivers
- Fix nested NMI issue with spurious interrupts on GICv3
- Don't allow GICv4.1 vSGIs when the CPU doesn't support them
- Various cleanups and minor fixes
