This is the prerequisite series:
https://lore.kernel.org/linux-pci/20250508-pcie-reset-slot-v4-0-7050093e2b50@linaro.org/

However, Bjorn gave some comments on it, and Manivannan has said that he
will send a new version.



That said, if you have problems with suspend/resume, perhaps you want to
try this patch instead:
https://lore.kernel.org/linux-pci/1744940759-23823-1-git-send-email-shawn.lin@rock-chips.com/

I don't know if Shawn intends to send a new version or not.


Kind regards,
Niklas
