It is more clear from user perspective to wrap the whole USB Type-C support under a single option that the user can select, then it is to always ask the user for every USB Type-C and USB Power Delivery driver separately.

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