SCMI patches in these series are all reviewed (all but one even by Sudeep)
so it is really up to Sudeep preference...(who is travelling now so it could
take a bit to reply)...moreover I am not sure if the SCMI patches in this
series could end up with wome trivial conflicts against the scmi patches
already queued at

	sudeep/for-next/scmi/updates

(at least the perf related ones 2 and 3 probably not)
