Subject: [PATCH 0/6] Enhancements for PCIe Cadence Controllers

Enhances the exiting Cadence PCIe controller drivers to support second
generation PCIe controller also referred as HPA(High Performance
Architecture) controllers.

Comments from the earlier patch submission on the same enhancements are
taken into consideration. The previous submitted patch links is

The changes are tested on 2 platforms. The legacy controller changes are
tested on an TI J7200 EVM and HPA changes are tested on an FPGA platform
available within Cadence.

Manikandan K Pillai (6):
  dt-bindings: pci: cadence: Add property "hpa" for PCIe controllers
  PCI: cadence: Add header support for PCIe next generation controllers
  PCI: cadence: Add architecture information for PCIe controller
  PCI: cadence: Add support for PCIe Endpoint HPA controller
  PCI: cadence: Add callback functions for Root Port and EP controllers
  PCI: cadence:  Update support for TI J721e boards
