Merge branch 'pci/controller/apple'

- Skip ports disabled in DT when setting up ports (Janne Grunau)

- Add t6020 compatible string (Alyssa Rosenzweig)

- Extract ECAM bridge creation helper from pci_host_common_probe() to
  separate driver-specific things like MSI from PCI things (Marc Zyngier)

- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with varying
  capabilities (Marc Zyngier)

- Directly set/clear INTx mask bits because T602x dropped the accessors
  that could do this without locking (Marc Zyngier)

- Move port PHY registers to their own reg items to accommodate T602x,
  which moves them around; retain default offsets for existing DTs that
  lack phy%d entries with the reg offsets (Hector Martin)

- Stop polling for core refclk, which doesn't work on T602x and the
  bootloader has already done anyway (Hector Martin)

- Use gpiod_set_value_cansleep() when asserting PERST# in probe because
  we're allowed to sleep there (Hector Martin)

- Move register offsets into SoC-specific structure (Hector Martin)

- Add T602x PCIe support (Hector Martin)
