I have switched to usb role switch framework instead of extcon and sent V2 based on the below feedback. https://patchwork.kernel.org/patch/10840659/ On V2, I have sent a patch series which uses " usb-connector " binding [1] and "usb-role-switch" property[2] [1] https://patchwork.kernel.org/patch/10852495/ [2] https://patchwork.kernel.org/patch/10852497/ Support for "usb-role-switch" compatible can be found in the below patch set https://patchwork.kernel.org/project/linux-usb/list/?series=97707 Please can you comment, is this approach is acceptable or not?
