Parade PS5511 is USB hub with 4 USB 3.2 compliant 5Gbps downstream(DS)
ports, and 1 extra USB 2.0 downstream port. The hub has one reset pin
control and two power supplies (3V3 and 1V1).

Changes in v2:
- Inherit usb-hub.yaml
- Fix bindings to reject port@5/device@5 for 3.0 hub correctly
- Minor string fixes

I would do this instead:
ports:
$ref: /schemas/graph.yaml#/properties/ports
patternProperties:
'^port@':
$ref: /schemas/graph.yaml#/properties/port
properties:
reg:
minimum: 1
maximum: 5

And here:
additionalProperties: true
properties:
reg:
minimum: 1
maximum: 5

> + - compatible
> + - reg
Already required by usb-hub.yaml.

Use unevaluatedProperties instead.
