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-v5.9-rc2 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.
