Merge branch 'pci/host/apple'

- 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
  access to USB type-A, Ethernet, Wi-Fi, Bluetooth devices; these require
  additional drivers of their own (Alyssa Rosenzweig)

- Add apple INTx, per-port, and MSI interrupt support (Marc Zyngier)

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

* pci/host/apple:
  PCI: apple: Configure RID to SID mapper on device addition
  iommu/dart: Exclude MSI doorbell from PCIe device IOVA range
  PCI: apple: Implement MSI support
  PCI: apple: Add INTx and per-port interrupt support
  PCI: apple: Set up reference clocks when probing
  PCI: apple: Add initial hardware bring-up
  PCI: of: Allow matching of an interrupt-map local to a PCI device
  of/irq: Allow matching of an interrupt-map local to an interrupt controller
  irqdomain: Make of_phandle_args_to_fwspec() generally available
