You don't have to submit a driver to submit a binding.
Examples of bindings that are not supported by any upstream driver:
Documentation/devicetree/bindings/net/wireless/esp,esp8089.txt
Documentation/devicetree/bindings/gpu/arm,mali-utgard.txt
Documentation/devicetree/bindings/gpu/arm,mali-midgard.txt
and there are probably more.
Best regards,
Thomas
