Typo: describes.

No, this binding describes PTN5110, not generic TCPCI. This is not
accurate commit description.

Sorry, cannot parse it. Please run it through native speaker, Google
grammar check, ChatGPT or some other way.

I don't think this is correct. First, this is binding for NXP chip, so
why generic implementation should be here? I would expect it in its own
dedicated binding.

Second, we rarely want generic compatibles. Care to share more details?
Are all details expected to follow spec, without need of quirks?

Best regards,
