For these two can we refactor in place? That's pretty much what seems

These sound like something that can be added incrementally?

I guess the big question is then if we can live with that.

In tree there's a few auxadc and comparator drivers in drivers/mfd, plus
things like arch/arm/plat-samsung/adc.c in the arch direcories. These
are all broadly similar to the at91 code that's been sent to IIO
