It would be good to merge the driver with > no known regressions. I don't know yet, I managed to get the icicle 5.6 up to 5.9 to allow mering this series on. However it does not get to detect a PCIe card. I can try and get some dmesg logs if that would be useful. The root port seems to get seen and shows up in lspci. I can't currently get to the boards physically due to the lockdown and issues with getting to our offices. -- Ben Dooks http://www.codethink.co.uk/ Senior Engineer Codethink - Providing Genius https://www.codethink.co.uk/privacy.html
