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.

Thanks for picking up on this Nicolas. Can you amend the MAINTAINERS
file with something along those lines such that PCIe binding and driver
changes are picked up by both the BCM2835 and BCM7XXX entries?
