From: Guenter Roeck <groeck@xxxxxxxxxxxx> 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.
Open question, since this still requires some work: Would the code, in its current form, be acceptable in -staging ? [ ... ]
