Hmm, I am not sure what can be elaborated further than what's already
there. The driver is written to be instantiated via DT and there's no
code that tries to do that via board code or anything like that. I am
guessing you maybe read the description differently. Can you help me
by giving an example of what you think needs clarifying?

Thanks,
