If it is too specific, some other similar drivers won't perfectly match
thus they will be placed again under dt-bindings/soc.

I was thinking about name "socinfo", but on the other hand why limiting
to SoC? I think there are many more devices which provide some kind of
read-only hardware information (type, revision, product ID, model etc),
therefore - hwinfo.

Thanks for the feedback.
