Maybe you found the root cause and fix already, but > investigating with my T14s Gen6 Snapdragon is on my TODO list. The T14s Gen6 Snapdragon has ps8830 redrivers, your patch works with them. Probably because they register as retimer-switch which takes a different path then mode-switch. I observed the issues with models that don't have the redriver chip, like Ideapad 5 14Q8X9 and Thinkbook 16 G7 QOY. They have a separate gpio-sbu-mux which don't get the mode-switch call when the patch is in. I could test on sc8280xp which also has separate gpio-sbu-mux switches if that brings some light to the issue. with best regards Jens
