[PATCH 0/2] PCI: {qcom-ep/tegra194}: Move endpoint cleanups to PERST# deassert handler

[Manivannan Sadhasivam via B4 Relay]

Hi,

This series moves the call to endpoint cleanup functions (dw_pcie_ep_cleanup()
pci_epc_deinit_notify()) to PERST# deassert handler in qcom-ep and tegra194
drivers. It aims to fix a crash that is seen with Qcom endpoint SoCs when host
asserts PERST# and the cleanup functions are called without refclk.

During the review of v1 [1], Bjorn suggested fixing up tegra194 driver as well
as both drivers share the same design and require refclk from host for
operation.

Testing
=======

The Qcom patch is tested on SM8450 development board. For tegra194, I'm
expecting someone in the Cc list or the community will do the testing.
