[PATCH 0/8] gpu: nova-core: convert registers to use the kernel register macro

[Alexandre Courbot]

nova-core carried its own helper macro to declare register types. Its
purpose was to be temporary since the beginning, and to serve as a
testbed to develop an equivalent that could be used kernel-wide.

That equivalent has now been merged, so it is time to retire the
nova-core local version.

The kernel register macro has evolved into something significantly
different from the one in nova-core, so it cannot be used as a drop-in
replacement. All declarations and sites using registers need to be
updated. No semantic change should happen as a result.

All the patches in this series could also be squashed into a single one
without altering their reviewability significantly. Actually I am
leaning towards that option since it doesn't make much sense to
partially convert the driver anyway. I'm leaving it in split state for
now in case this drives more people towards review. :)

I hope to be able to merge this quickly so we can rebase in-flight
series to use the updated register syntax.

This series is based on drm-rust-next as of 2026-03-18.
