Mark and I can queue PSCI patches as we usually do, we agreed they would go via Rafael's tree (thanks) because of dependencies with the PM tree (that did not turn out to be there so we could have sent them to arm-soc just as well as we usually do), next cycle if and when there are patches to be queued we will queue them up and send them upstream ourselves.
