Another issue that is affecting current mainline for kevin is fixed
with [1]. As usual, I have a tracking branch for 5.5 for different
Chromebooks with some not yet merged patches that makes things work
while are not fixed [2]. For kevin only the mentioned ASoC patch [1]
and the pcie fix [3] should be needed. Other than that display is
working for me on Kevin.



It's likely that any PCI driver that uses PCI IO with that controller will
suffer the same fate.

Vicente - can you try the patch that has been proposed and verify it fixes
the issue for you?

Thanks, ...

Hi Robin, Andrew and Enric,
thank you all for the quick responses!
I can confirm that patch [3] fixes the issue reported in this email and
that [1] fixes the other issue reported on the other email.

Pleased to hear this is working for you now.

Are you happy to give a tested-by tag for [3]?

Yes, feel free to apply this tag.
Using it just now and the wlan at the other side of the PCIe bus is detected.
