  gpu: host1x: Add context bus (2022-06-01 11:50:42 +0200)

I realize that this is quite late, but as mentioned in the tag
description, this doesn't actually add anything new and is only
to simplify dependency handling for a new feature that we have
planned for v5.20, so it'd be great if we can still get this
in.

Thanks,
Thierry

drm/tegra: Preparatory work for v5.19

This contains a single patch from a series that's ready to go for v5.10
but is also a shared build-time dependency for an IOMMU series that is
planned for v5.20. The idea is to take this into v5.19 to fulfill that
dependency and remove the need for close coordination for the two
series.
