Thank you for your patch. There is something to discuss/improve.

Instead: "Top Level Mode Multiplexer pin controller node in Qualcomm
MDM9615 SoC."

I see this pattern is coming from other file, so I will fix all of them.

Drop it, it's included from tlmm-common

No sd-like functions? If so, then drop oneOf

Add example of -state with and without -pins node.

You dropped it with conversion.
