[PATCH v2 0/4] Introduce usb-hub.yaml binding and add support for Parade PS5511

[Pin-yen Lin]

This series introduces usb-hub.yaml for on-board USB hubs, and use it for
the newly-added Parade PS5511 binding and the existing Realtek RTS5411
hub controller.

Also add support for Parade PS5511 in onboard_usb_dev.c

Patch 1 introduces usb-hub.yaml as the bindings for on-board USB hubs
Patch 2 adds the binding for Parade PS5511
Patch 3 modifies realtek,rts5411.yaml to adapt usb-hub.yaml
Patch 4 adds the support for Parade PS5511 in onboard_usb_dev.c

Link to v1: https://lore.kernel.org/all/20250328082950.1473406-1-treapking@chromium.org/


Changes in v2:
- Introduce usb-hub.yaml
- Modify parade,ps5511 and realtek,rts5411 to use usb-hub.yaml
- Minor fixes on parade,ps5511.yaml

[PATCH v2 2/4] dt-bindings: usb: Add binding for PS5511 hub controller

[Pin-yen Lin]

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).

Signed-off-by: Pin-yen Lin <treapking@chromium.org>

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

Drop these 3.

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

Already required by usb-hub.yaml.

Use unevaluatedProperties instead.
