Add a binding for the USB type-c switch controls found on some ChromeOS
Embedded Controllers (ECs). When this device is a mode switch, it takes
one DisplayPort (DP) port as input and some number (possibly zero) of
USB SuperSpeed ports (bundles of USB SS lanes) as input, and muxes those
lanes into USB type-c SuperSpeed lanes suitable for the SSTRX1/2 pins on
a usb-c-connector. When this device is an orientation switch, it
redirects the DP lanes to the proper USB type-c SSTRX lanes.

Ah, and wrong placement. There is no hardware called "chrome", please
don't stuff things there. USB switches go to other USB switches (git
grep usb-switch.yaml will give you hints).

Best regards,
Krzysztof
