Noralf - you had analyzed what drivers are (yet) to migrate to to the common fbdev emulation. Link: https://lore.kernel.org/dri-devel/34e654ae-0cc9-e393-ac02-e4ac6eda60f6@tronnes.org/ rmada gma500 amd omapdrm nouveau i915 msm tegra exynos radeon rockchip Maybe add this list to todo.rst - and if someone knows about it we could have a small description what is required before a driver can migrate. I can cook up the patch if anyone thinks this is useful.
