[PATCH v4 0/9] USB host support for Raspberry Pi 4 board (64-bit)

[Sylwester Nawrocki]

Hi all,

This patch series adds USB host support for Raspberry Pi 4 board. 
It includes the Broadcom STB PCIe controller driver ported from Linux 
kernel, a memory mapping update for the xHCI controller on PCIe bus
for 64-bit builds and some related fixes and updates in the usb/xhci 
and the pci driver core code.

The 32-bit ARM part has be excluded from the series and will be posted
separately.

The difference comparing to previous version is only in the config update
patch "configs: Enable support for the XHCI controller on RPI4 board (ARM
 64-bit)".

The patch series is based on v2020.07-rc1 tree.

Thanks,
Sylwester

  usb: xhci: Add missing cache flush in the scratchpad array
    initialization
  usb: xhci: Use only 32-bit accesses in xhci_writeq/xhci_readq
  pci: Move some PCIe register offset definitions to a common header
  pci: Add some PCI Express capability register offset definitions
  pci: Add driver for Broadcom BCM2711 SoC PCIe controller
