Do you use the mainline DTS or the vendor DTS to see this issue?
For (open)SUSE we use downstream DTS.
This is popular and bad at the same time. We as the mainline kernel
developer cannot guarantee that this works as expected. A lot of issues are
caused by mixing vendor DTS with mainline kernel, so in general (not for
this specific issue) you are on your own with this approach.
Yep, I am aware of that. I am still trying to recover after recent
gpio-ranges fiasco, also still working on fixing non-exported firmware
clocks, which break HDMI output on some of the devices.
I guess, these firmware clock issues are only reproducible with vendor DTS?
I know this is a little bit off topic but except from overlay support, can
you provide a list of most missing features of the mainline kernel / DTS?
Well, 260+ overlays for free is not insignificant benefit. Beside few
breakages from time to time using downstream device tree works fine.
I think the better approach is to add the missing steps for overlay
support in mainline.
Best regards
Regards,
Ivan
