I just noticed that I based this version on top of a local branch that
will cause conflicts if you apply this to either 5.3 or linux-next. I'll
resend this later rebased onto drm/tegra/for-next, so it should apply
cleanly on at least linux-next. drm/tegra/for-next also contains this:

drm/tegra: Fix ordering of cleanup code
Commit Fixes: b9f8b09ce256 ("drm/tegra: Setup shared IOMMU domain after
initialization") changed the initialization order of the IOMMU related
bits but didn't update the cleanup path accordingly. This asymmetry can
cause failures during error recovery.

which will conflict with the ->load() and ->unload() removal patch.
If for some reason you can't use linux-next, it shouldn't be terribly
complicated to backport this to v5.3, though.
