    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.
