RE: Custom DTS child node unknown node type

Thanks, the missing /dts/ did the trick. It's the little things like this that waste a lot of time when you're trying to learn a new system, dealing with the "unknown unknowns" 😞

Hello,

It is explained here where the build system will look for bindings: https://docs.zephyrproject.org/latest/build/dts/bindings-intro.html#where-bindings-are-located.

[quote user=""]in my board or board/bindings directories[/quote]

I haven't tried placing it in the boards directory, but I believe it should still be boards/dts/bindings/gpio/<your binding>.yaml

If you just need to control some pins directly from the application without using a driver that follows the zephyr driver model, you may also consider just using the /zephyr,user node. Then you will not have to define a custom binding.

Best regards,

Vidar
