Drop it. It is trivial and it is not needed to illustrate your device bindings. All clock bindings use it...I'm fine with that. I don't know if Jerome agrees with that. Wait for him. See what he says.This is a simple change related to your binding example. Krzysztof is one of the DT maintainer. Please follow his recommendation.
Okay. Got it.
