This patch series introduces a mechanism for setting USB Type-C alternate mode priorities. It allows the user to specify their preferred order for mode selection, such as USB4, Thunderbolt, or DisplayPort. A new sysfs attribute named 'priority' is exposed to provide user-space control over the mode selection process. This series was tested on a Android OS device running kernel 6.16.
