I'm missing the big picture here, and i don't see an example of these
properties being used. However, since you reference an old networking
example, for RGMII delays....

adi,rx-internal-delay-ps should be deprecated, we now have the generic
rx-internal-delay-ps. The point about using -ps is however still
valid.

However, i would not like to see pinctl DT properties used in place of
rx-internal-delay-ps. How the Ethernet MAC driver implements
rx-internal-delay-ps is left open, so calling a pinctl API to set the
skew is fine by me. And if the real use case has nothing to do with
networking, then i don't care.
