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
