1. No such vendor. You need to test against entire bindings.
2. Looks heavily incomplete - no resources. Compatible and hardware
description looks also incomplete - what is osf? It's exactly ONE
device? Why do you use bus suffix? Please start with writing bindings or
DTS101 slides.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
If you cannot find a name matching your device, please check in kernel
sources for similar cases or you can grow the spec (via pull request to
DT spec repo).
