Dear Rob, and other DT maintainers, (apologies, fixed typos in earlier mail)

Some controllers have dedicated R/B pin (Ready/Busy) while others may use GPIO instead. It's the way a hardware controller is designed.
Request you to please consider Ack from MTD Maintainers 'at-least' for generic NAND DT bindings. There is already a discussion going in a separate thread for which there are still no replies [1].
