Which predated FDT support in Linux by more than a decade, with the
latter predating even p1275?

While I see merit in compatibility with other existing OSes, I prefer not
to deviate from standard DT bindings, if they exist.

Over time, we've even migrated from Renesas-specific DT bindings to
standard DT bindings, in already upstreamed SoC support.

If needed, I guess a script can be written to convert DTS files from the
old to the new syntax?

Thanks!
