USB Type-C Port Controller (TCPC) #################################
Overview
TCPC <tcpc-specification_>_ (USB Type-C Port Controller)
The TCPC is a device used to simplify the implementation of a USB-C system
by providing the following three function:
VBUS and VCONN control USB Type-C <usb-type-c-specification_>_:
The TCPC may provide a Source device, the mechanism to control VBUS sourcing,
and a Sink device, the mechanism to control VBUS sinking. A similar mechanism
is provided for the control of VCONN.
CC control and sensing: The TCPC implements logic for controlling the CC pin pull-up and pull-down resistors. It also provides a way to sense and report what resistors are present on the CC pin.
Power Delivery message reception and transmission USB Power Delivery <usb-pd-specification_>_:
The TCPC sends and receives messages constructed in the TCPM and places them
on the CC lines.
.. _tcpc-api:
The TCPC device driver functions as the liaison between the TCPC device and the application software; this is accomplished by the Zephyr's API provided by the device driver that's used to communicate with and control the TCPC device.
