This series aims at providing support for Raspberry Pi 4's PCIe
controller, which is also shared with the Broadcom STB family of
devices.

There was a previous attempt to upstream this some years ago[1] but was
blocked as most STB PCIe integrations have a sparse DMA mapping[2] which
is something currently not supported by the kernel.  Luckily this is not
the case for the Raspberry Pi 4.

Note that the driver code is to be based on top of Rob Herring's series
simplifying inbound and outbound range parsing.

Changes since v2:
  - Redo register access in driver avoiding indirection while keeping
    the naming intact
  - Add patch editing ARM64's config
  - Last MSI cleanups, notably removing MSIX flag
  - Got rid of all _RB writes
  - Got rid of all of_data
  - Overall churn removal
  - Address the rest of Andrew's comments

Changes since v1:
  - add generic rounddown/roundup_pow_two64() patch
  - Add MAINTAINERS patch
  - Fix Kconfig
  - Cleanup probe, use up to date APIs, exit on MSI failure
  - Get rid of linux,pci-domain and other unused constructs
  - Use edge triggered setup for MSI
  - Cleanup MSI implementation
  - Fix multiple cosmetic issues
  - Remove supend/resume code
