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.
