Do you think it would help to split the iio codebase into a smaller part
for the relatively clean drivers that can be put into shape for
drivers/iio, and the bulk of the code that stays in staging for a bit
longer, until it gets converted to the new one in small chunks?

That may be less frustrating than trying to do it all at once. In particular,
you could do major internal rewrites much faster if you don't have
to immediately worry about breaking dozens of drivers in the process.
