Maybe Bjorn can pitch in with his thoughts here.

Maybe Bjorn can pitch in with his thoughts here as he may have more
historical context, but I personally think that since the mapping
between the pin controller local number space and the pins in the
GPIO controller local number space is 1:1 (same) here, adding
gpio-ranges property here is optional (as it provides little
additional information).
But I might have missed something here, so I will wait for more
thoughts from Bjorn.
Thanks,
