How about introducing an rs485 generic gpios property instead of xlnx
private one? See also rs485-term-gpios and rs485-rx-during-tx-gpios.
Also note that every kernel driver expects to use RTS for this
purpose.
So why not give this driver the option to choose a gpio instead of its
native RTS? And from there on use the rts route?
What if someone wants to use normal (non-rs485) RTS on a GPIO instead
of the native pin?
@Rob Herring
I am curious to know how the rs485 maintainers look at this.
Ask them.
Funny, your name is the only one listed under the maintainers in
Documentation/devicetree/bindings/serial/rs485.yaml
And there is no mention of (RS-)485 in MAINTAINERS.
We already have 'rts-gpios'. If that's what's always used, then perhaps
we should use that in the RS485 case too?

Sounds like a good idea.
