#      - Revert emulation of Marvell Armada A3720 expansion ROM because it
#        doesn't work as expected (Marek Behún)
#     
#      - Assert PERST# in Apple M1 driver to fix initialization when booting
#        from bootloaders using PCIe, such as U-Boot (Marc Zyngier)
#     
#      - Describe PERST# as active low in Apple T8103 DT and update driver to
#        match (Marc Zyngier)
#     
#     * tag 'pci-v5.16-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
#       PCI: apple: Fix PERST# polarity
#       arm64: dts: apple: t8103: Mark PCIe PERST# polarity active low in DT
#       PCI: apple: Follow the PCIe specifications when resetting the port
#       Revert "PCI: aardvark: Fix support for PCI_ROM_ADDRESS1 on emulated bridge"
