Subject[PATCH 1/2] dt-bindings: chrome: Add cros-ec-typec mux props
Date
Add properties for mode, orientation and USB data role switches for
Type C connectors. When available, these will allow the Type C connector
class port driver to configure the various switches according to USB PD
information (like orientation, alt mode etc.) provided by the Chrome OS
EC controller.
