   5           USB Type-C Specification defines a cable and connector for USB where
   6           only one type of plug is supported on both ends, i.e. there will not
   7           be Type-A plug on one end of the cable and Type-B plug on the other.
   8           Determination of the host-to-device relationship happens through a
   9           specific Configuration Channel (CC) which goes through the USB Type-C
  10           cable. The Configuration Channel may also be used to detect optional
  11           Accessory Modes - Analog Audio and Debug - and if USB Power Delivery
  12           is supported, the Alternate Modes, where the connector is used for
  13           something else then USB communication.
  14
  15           USB Power Delivery Specification defines a protocol that can be used
  16           to negotiate the voltage and current levels with the connected
  17           partners. USB Power Delivery allows higher voltages then the normal
  18           5V, up to 20V, and current up to 5A over the cable. The USB Power
  19           Delivery protocol is also used to negotiate the optional Alternate
  20           Modes when they are supported. USB Power Delivery does not depend on
  21           USB Type-C connector, however it is mostly used together with USB
  22           Type-C connectors.
  23
  24           USB Type-C and USB Power Delivery Specifications define a set of state
  25           machines that need to be implemented in either software or firmware.
  26           Simple USB Type-C PHYs, for example USB Type-C Port Controller
  27           Interface Specification compliant "Port Controllers" need the state
  28           machines to be handled in the OS, but stand-alone USB Type-C and Power
  29           Delivery controllers handle the state machines inside their firmware.
  30           The USB Type-C and Power Delivery controllers usually function
  31           autonomously, and do not necessarily require drivers.
  32
  33           Enable this configurations option if you have USB Type-C connectors on
  34           your system and 1) you know your USB Type-C hardware requires OS
  35           control (a driver) to function, or 2) if you need to be able to read
  36           the status of the USB Type-C ports in your system, or 3) if you need
  37           to be able to swap the power role (decide are you supplying or
  38           consuming power over the cable) or data role (host or device) when
  39           both roles are supported.
