4 tristate "USB Type-C Connector System Software Interface driver"
9 USB Type-C Connector System Software Interface (UCSI) is a
10 specification for an interface that allows the operating system to
11 control the USB Type-C ports. On UCSI system the USB Type-C ports
15 that are equipped with Embedded Controller and USB Type-C ports.
17 UCSI specification does not define the interface method, so depending
