That's why I sent this as an RFC. I thought about this too but have no good idea how to represent this in DT while keeping the existing bindings.  So I just thought this small driver would be the easier way, possibly being useful for other potential usecases. But sure, if this is the only way to go I'll have to RFC this at the SFP driver side asking for any ideas how this could be achieved. > I have also doubts we actually want it in DT, because we tie the > limitation of Linux drivers to bindings. > > > Best regards, > Krzysztof Best regards, Jonas
