Hi Heikki, This patch series expands support for partner and cable discover in the UCSI driver. There are a few pieces here. 1. Some cleanup of the GET_CABLE_PROP definitions in ucsi.h. 2. Cable discovery and registration with the USB Type-C connector class. 3. Partner/Cable identity registration with the USB Type-C connector class. 4. SOP' alternate mode registration with the USB-C connector class using a cable plug. These have been tested on a v6.6 kernel build running a usermode ppm with a Realtek EVB. Let me know if you have any questions.
