The ports definition currently defined in the usb-switch.yaml fits standards devices which are either recipient of altmode muxing and orientation switching events or an element of the USB Super Speed data lanes. This doesn't necessarely fit combo PHYs like the Qualcomm USB3/DP Combo which has a different ports representation. Move the ports definition to a separate usb-switch-ports.yaml and reference it next to the usb-switch.yaml, except for the Qualcomm USB3/DP Combo PHY bindings.

Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a
|
|
functionally separate USB SubSystem for Altmode/Analog Audio Switch
|
|
accessible over an I2C interface.
|
|
The Audio Headphone and Microphone data path between the Codec and the
|
|
USB-C Mux subsystems are external to the IC, thus requiring DT port-endpoint
|
|
graph description to handle USB-C altmode & orientation switching for Audio
|
|
Accessory Mode.
