This series adds Rust abstractions for the auxiliary bus.
It implements the required abstractions to write auxiliary drivers and create
auxiliary device registrations. A driver sample illustrates how the
corresponding abstractions work.
The auxiliary abstractions are required for the Nova driver project, in order to
connect nova-core with the nova-drm driver.
This patch series depends on [1] (taken through the nova tree for v6.15); a
branch containing the patches, including the dependency can be found in [2].
