[PATCH v2 0/2] usb: misc: Add Terminus FE1.1 USB2.0 Hub support

[Yixun Lan]

This series try to add support for Terminus FE1.1 USB2.0 Hub.

The FE1.1 Hub provide interesting choice of selecting power supply from
either 3.3V or 5V, if need to use integrated 5V to 3.3v regulator, the 5V
supply should be used. Otherwise, 5V pin can be set to NO-Connection,
and use the 3.3v external supply source.

Changes in v2:
- drop patch 1, not add Terminus vendor prefix
- reuse compatible data, no introduce new one
- fix binding
- Link to v1: https://lore.kernel.org/r/20260317-03-usb-hub-fe1-v1-0-71ec3989f5be@kernel.org

[PATCH v2 1/2] dt-bindings: usb: Add support for Terminus FE1.1s USB2.0 Hub controller

[Yixun Lan]

Terminus FE1.1s is USB2.0 protocol compliant 4-port USB HUB, It support
MTT (Multiple Transaction Translator) mode, the upstream port supports
high-speed 480MHz and full-speed 12MHz modes, also has integrated 5V to
3.3V, 1.8V regulator and Power-On-Reset circuit.

Introduce the DT binding for it.
