Don't need 'oneOf' for 1 entry.

No need for generic descriptions. That's all 'reg-names'...

Why not 'tsn' as above instead of reg? In any case, the correct form is:

items:
  - const: reg
  - const: ptp

Use the preferred 'ethernet-ports'.

Add:

unevaluatedProperties: false

Don't show status in examples.
