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.
