Merge branch 'remotes/lorenzo/pci/cadence'

- Convert cadence to use standard "dma-ranges" DT property instead of its
  own "cdns,no-bar-match-nbits" (Kishon Vijay Abraham I)

- Fix pm_runtime_put_sync() issues in cadence error paths (Kishon Vijay
  Abraham I)

- Add PTR_ALIGN_DOWN macro (Kishon Vijay Abraham I)

- Convert cadence r/w accessors to only 32-bit accesses (Kishon Vijay
  Abraham I)

- Add cadence support to start Link and check Link status (Kishon Vijay
  Abraham I)

- Allow custom PCI ops for cadence-based drivers (Kishon Vijay Abraham I)

- Remove "mem" from cadence reg binding since it's not memory and it
  overlaps the PCIe config and memory region (Kishon Vijay Abraham I)

- Add cadence ->cpu_addr_fixup() for platforms that require absolute
  addresses in the ATU, not just offsets (Kishon Vijay Abraham I)

- Update cadence Vendor IDs using local management registers, not
  architected config space (Kishon Vijay Abraham I)

- Add cadence endpoint driver MSI-X support (Kishon Vijay Abraham I)

- Add bindings and driver for TI J721E SoC, supporting both host and
  endpoint mode (Kishon Vijay Abraham I)
