Warning squiggles "Unknown node type" in DTS overlay with custom DTS binding

[lexologe]

Hello,

my project has custom DTS bindings in ./dts/bindings and it compiles and works fine. If I open the DTS overlay file that uses the custom DTS bindings, the compatible node is marked as a warning. See my attached screenshot.

I already tried to add 

"devicetree.modules": [

]

to my .vscode/settings.json but I do not know exactly what to add there.
