Please describe the hardware in details. Above sentences don't help me
to understand this.

You are using usb-switch.yaml properties in phy node, which raises
questions whether this is actually complete. It might be, but commit msg
is so vague that I have doubts.

Also, why only one port?

Or wait... you already have ports! two of them. This needs to stop, why
are you adding more?

Best regards,
Krzysztof
