So only patches [2/5] and [3/5] of this series would have to be upstreamed in case you're still interested in pursuing them. Note that a related DT property was introduced with 103dcf2ea2df. Also note that you got some review comments on this series that may still need to be addressed. Just thought I'd let you know as I rediscovered this thread today when flushing out old e-mails from my inbox. Thanks, Lukas
