Nothing prevents it from being used (if you are referring to our
previous conversations) besides this information not being available in
public DTS (I simply did not know) and the fact that all these many
fixes - however necessary they are - distract from the main topic of
this series: bringing INTF TE support to DPU1.

I'll fit in that patch though, as I have to send v4 anyway.
