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
