The driver will go upstream eventually, but there are a quite a few infrastructure dependencies, both in IIO and other parts of the kernel, that need to go upstream first. Sometimes it makes sense to split things into smaller parts and submit those things that are simple and ready rather than accumulating a patch-bomb of 50+ patches. > > It does make any sense to expose an ABI if no one is using it. I'm using it :)
