Merge tag 'irqchip-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip updates from Marc Zyngier:

- API updates:

  - Treewide conversion to generic_handle_domain_irq() for anything
    that looks like a chained interrupt controller

  - Update the irqdomain documentation

  - Use of bitmap_zalloc() throughout the tree

- New functionalities:

  - Support for GICv3 EPPI partitions

- Fixes:

  - Qualcomm PDC hierarchy fixes

  - Yet another priority decoding fix for the GICv3 pseudo-NMIs

  - Fix the apple-aic driver irq_eoi() callback to always unmask
    the interrupt

  - Properly handle edge interrupts on loongson-pch-pic

  - Let the mtk-sysirq driver advertise IRQCHIP_SKIP_SET_WAKE
