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.
