From: Cristian Birsan <cristian.birsan@microchip.com> This patch set adds initial driver support for Microchip USB Type-C Port Controller (TCPC) embedded in sama7g5 SoC. The controller does not implement power delivery and the driver uses dummy functions to register the port with TCPM. The current silicon version is not able to trigger interrupts so the driver will poll for changes on CC1/CC2 lines. Support for sink is implemented and tested with an USB device. The plan is to extend the driver and add source support.
