ICYMI, patch [1/5] of this series got accepted back in the day
and patches [4/5] and [5/5] appeared in slightly modified form in v5.19
(commits b54f7a922d33 and 5ff33917faca).

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
