Similar to the QCP, the EVK does not use Parade PS8830 retimers on the
SS0. Instead, each port uses an FSUSB42 USB switch to handle orientation
switching for the SBU lines.

> Could you please point out, why?
According to the schematic, there is a regulator and a retimer (PS8830).
However, as mentioned above, the retimer is not connected to USB 0 and
is therefore not used in the EVK. As a result, the regulator is left
unused in this context.

It is used to switch data lines between USB Type-C orientation detection
and DisplayPort AUX channels. When this GPIO is high, USB0 operates in
orientation detection mode.

This pin functions similarly to usb-1-ss0-sbu-state; it controls the
data switch between signals from the USB connector and WLAN data.
