  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
 12	  function autonomously by default, but in order to get the status of
 13	  the ports and support basic operations like role swapping, the driver
 14	  is required. UCSI is available on most of the new Intel based systems
 15	  that are equipped with Embedded Controller and USB Type-C ports.
 16
 17	  UCSI specification does not define the interface method, so depending
 18	  on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this
 19	  driver only provides the core part, and separate drivers are needed
 20	  for every supported interface method.
 21
 22	  The UCSI specification can be downloaded from:
 23	  https://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html
