[PATCH v2 00/10] USB host support for Raspberry Pi 4 board

[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 32-bit and 64-bit system builds and some related fixes and updates
in the usb/xhci and the pci driver core code.

This iteration includes minor corrections in patches 7, 9, 10 addressing
review comments.

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 STB PCIe controller
