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

24	  called typec_ucsi.
