I doubt this is "GPIO". General Purpose? I think not. It seems to be about boot mode. If you need a userspace ABI, then add sysfs files to this firmware driver instead of bridging it to the GPIO subsystem. However I can be argued down from usecases etc that it is used as GPIO but I need to push back on this. Yours, Linus Walleij
