Although I didn't find an example, I am quite sure YAML format can have exclusive properties. If not, it should be added ;) I'll try again to get some information from people more experienced with YAML. But we don't depend on it. > Regarding the device tree changes: I am not very familiar with the > needed documentation changes, YAML bindings or what needs to be done > for new bindings in general.

No need to. Luckily, the I2C main bindings file is still text, so it is easy to modify. I will send a patch out in a few minutes, so you can base your driver code on that. Converting to YAML is a completely different step, not related to your patch here. (Sidenote: I am looking for volunteers to do that) I think this covers it?
