- Make of_phandle_args_to_fwspec() generally available (Marc Zyngier)

- Allow matching of interrupt-maps local to interrupt controller or PCI
  device (Marc Zyngier)

- Add Apple SoC (e.g., M1) PCIe host controller driver, which enables

- Configure apple Requester-ID-to-Stream-ID mapper for IOMMU (DART) support
  (Marc Zyngier)
