Well, we tried to make it without an explicit config option but it does not hurt to have one. Your proposal works fine for 3 out of the 4 possible combinations. I think it is unlikely that the combination TOUCHSCREEN_TSC2007=y IIO=m is needed at all (we configure as much as possible as =m in our kernel). Patch v9 will come next (where I have also moved this iio driver patch to be 8/8).
