I can only pick the last commit. I have sent my PR for v6.9 already and was deferring this to v6.10 The changes look good to me. If it doesn't conflict much with -next SCMI content, then I am happy to ack and you can take all of them together. Otherwise we can revisit strategy at -rc1. Thoughts ? -- Regards, Sudeep
