From: Vidya Sagar
Date: Thu Oct 13 2022 - 14:44:39 EST


This patch series contains enhancements to the pcie-tegra194.c driver
that works for both Tegra194 and Tegra234 SoCs and for both RootPort
and Endpoint modes.

This patch series depends on the following series in the same order

PCI: designware-ep: Fix DBI access before core init
https://patchwork.ozlabs.org/project/linux-pci/list/?series=322681

PCI: endpoint: Rework the EPC to EPF notification
https://patchwork.kernel.org/project/linux-pci/list/?series=683493

Add DeInit support in the PCIe Endpoint framework
https://patchwork.kernel.org/project/linux-pci/list/?series=685157

V3:
* Addressed review comments from Bjorn
* Added new patches to the series

V2:
* Addressed review comments from test bot and Vinod
