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 the usb-testing branch merged with a chromeOS 6.8-rc2 kernel. Let me know if you have any questions. Thanks, Jameson Changes in v3: - Fixed CC stable. Changes in v2: - Re-ordered memset call and null assignment when unregistering partners and cables. - Supports registering partner and cable identity with UCSI versions before v2.0. - Shortened lines to within 80 characters with the exception of two error log lines with three indentations. - Tested on usb-testing branch merged with chromeOS 6.8-rc2 kernel.
