So, I actually agree that in the long term getting resource names in
the DT would be a generally good thing.

But doing so is a *huge* change in one of the very core semantics of
all the DT bindings.  It's not something that should be done lightly
or quickly.  It absolutely should not be tied to how this is handled

the longer you take to change, the more complex will it be to
change.

No, not really.

The longer we spend discussing the validity of _byname(), more
boards/archs/whatnot will be converted to DT without _byname() and after
a certain amount of them are converted, noone will be willing to change
and validate everything again.

I'm not discussing the validity of _byname (Russell King is, but
that's not an argument I have a position of).  What I'm saying is that
the kernel internal use of byname, and named resources in the DT are
different things which should be approached independently.
