OK, your argument is valid and I would be better on the safer side.
I will remove the binding for the Type-C controller from this series
and post it a bit later including the driver.

I will reduce this series to just add basic support for the board.
Can I keep your R-b tag for the Type-C dt-binding for the future
submission or should I better remove it?
