Looks like you have 4 or 6 entries, not 1. Need to define what each one is.

This defines a single entry. I believe you want:
items: - const: tx - const: rx

No need for this. Tools add pinctrl properties.

Doesn't match the schema.

Is it 4 or 6 entries?

Not documented.

This is a clock provider too?
