The actual code is all obviously out of tree, I'd expect any Android BSP to contain at least some usage of it (though often just the basic GPIO one for CPU vendor ones).

I'd not characterise it as a massive problem (and wakelocks won't hold back anything that doesn't have other problems). I suspect that the code for a Samsung phone with the 30 pin connector will show something interesting, though I can't say I've actually looked. For things like headset detection there's already ways to support things in mainline and we should just end up hooking extcon into the central support for these things.
