Hi Hans, These have been in my queue for a while now. For some reason I've been under the impression that there was still an issue with them, but that was a misunderstanding. Saranya and Balaji, I'm really sorry about that. Hans, I don't know if you remember these, but they address an issue where the device mode does not work (I think on APL). I believe static mode is used always except on Cherrytrail. You had reported that using the static mode creates a conflict on some CHT boards that have ACPI tables that also write to the mux registers. To prevent the use of the static mode on Cherrytrail the property is used.
I've given this a test-run on a Cherry Trail device which used ACPI _AEI handlers to do the mux switching as well as on 2 models (1 with micro-usb id-pin, one with a Type-C fusb302 controller) where the kernel does the switching. I can confirm that with these patches applied things still work fine on all 3 models. With that said I do have some review remarks on the second patch I will reply to that patch with my remarks. Regards, Hans
