staging: typec: USB Type-C Port Manager (tcpm)
This driver implements the USB Type-C Power Delivery state machine
for both source and sink ports. Alternate mode support is not
fully implemented.
The driver attaches to the USB Type-C class code implemented in
the following patches.
usb: typec: add driver for Intel Whiskey Cove PMIC USB Type-C PHY
usb: USB Type-C connector class
This driver only implements the state machine. Lower level drivers are
responsible for
- Reporting VBUS status and activating VBUS
- Setting CC lines and providing CC line status
- Setting line polarity
- Activating and deactivating VCONN
- Setting the current limit
- Activating and deactivating PD message transfers
- Sending and receiving PD messages
The driver provides both a functional API as well as callbacks for
lower level drivers.
