Toshiba TC9564 bindings and DTS should be posted completely. We spent
great amount of time on discussing already and I pointed more than once
that big picture is missing.

You are not describing here parts of a SoC.

You are describing one, single device how the host sees it and DT
maintainers (and writing bindings) ask for complete picture in such cases.
