Hi Ezequiel,
The fix is just re-organizing the code a bit. Just pushed a possible fix for that (following the IPU handling by Paul Cercueil), please feel free to test this:
https://gitlab.collabora.com/linux/0day/-/commits/jz4780-drm-hdmi-module-fix...
Works well (after doing a minor fix to the CI20 defconfig)!
FWIW, my test setup uses mainline vanilla U-Boot v2020.07. The kernel is loaded via TFTP. Debian mipsel is mounted via NFS (which means dm9000 works). I'm testing with weston and modetest.
Note that enabling DRM_INGENIC_IPU will make the driver fail to load, as the IPU is not optional (and not present on ci20.dts). A minor thing to fix.
Cheers, Ezequiel
And it seems to differ significantly from what Paul has developed recently to make it work. It seems to be quite lucky that we have a working setup now :)
Nikolaus, Paul: Do you have plans to submit these?
Yes, as soon as we are sure that it works (and when it doesn't).
But thanks to your work it is now much easier to improve things, since we are no longer looking for a break-through but just have to avoid regressions.
If not, I'll be happy to get them out the door for review.
Let it mature a little first and have it tested on more setups and rebased to mainline v5.9-rc2 :)

DRM drivers follow their own schedule, you should rebase to drm-misc-next instead.
With the comment from Paul, I think it is best if you push them for review.
My patch set based on v5.9-rc2 is here (including one EFUSE patch which I have included only for making my Ethernet interface work for testing):

Please take it, do the required squashes and rebasing and post them for discussion to the appropriate lists.
I hope you are well. Do you plan to do the squash and rebase and posts?
BR and thanks, Nikolaus
