DSI code for VBT has a set of ugly GPIO hacks, one of which is direct talking to GPIO IP behind the actual driver's back. An attempt to fix that is here. If I understood correctly, my approach should work in the similar way as the current IOSF GPIO. Hans, I believe you have some devices that use this piece of code, is it possible to give a test run on (one of) them?
