This usually needs to be accompanied by a corresponding addition to the
memory controller driver. Unfortunately it seems like the changes
targetted at v5.17-rc1 never made it upstream, so I've queued them up
again for v5.18-rc1. They should show up in today's linux-next. When
they do, can you please follow up with a patch to the memory controller
driver that adds the various registers for these clients?

Thanks,
Thierry
