[PATCH 0/5] PCI: endpoint: Add EPC 'deinit' event and dw_pcie_ep_linkdown() API

From: Manivannan Sadhasivam
Date: Thu Jun 06 2024 - 03:27:25 EST


Hi,

This series includes patches that were left over from previous series [1] for
making the host reboot handling robust in endpoint framework.

When the above mentioned series got merged to pci/endpoint, we got a bug report
from LKP bot [2] and due to that the offending patches were dropped.

This series addressed the issue reported by the bot by adding the stub APIs in
include/pci/pci-epc.h and also removed the unused dwc wrapper as concluded in
[3].

Testing
=======

This series is tested on Qcom SM8450 based development board with 2 SM8450 SoCs
connected over PCIe.
