Do you mean I should remove the '|' please ? (I didn't find examples of use of
dt-preserve-formatting in Documentation/devicetree/bindings/)

I'm happy to replace the instance ID with  another solution.
In our case the remoteproc instance does not have a base address

What do you recommend in this case please ?
