Is it generic naming?
Also.. why we support two types of GPIO functions?
If you want to support generic GPIO, you should be replaced new gpio functions completely.

should be moved to upper line.
And need the brace at this else state.

- We can do it, we can have only 1 set of gpio functions.

Yes it is exynos5 specific as in EXYNOS5 the gpio banks are not
continuous and the number of pins are also not uniform across the gpio
banks hence the exsistting funcion gives us wrong values. Hence this
calculation will change for Exynos5 and we need to a dedicated
function, do suggest me if you have any other idea.
