This is my plan ;) In fact, "berlin4ct" related binding is also missing.
I want to convert Documentation/devicetree/bindings/arm/syna.txt
to yaml, then add missing bindings. But it's too late for 5.15,

If it's fine to keep as370.dtsi without board user(s), we can drop
this patch. I will solve this issue in next development window.

Thanks
