In most devices, the button ladder is not actually derived from VDDIO but from a constant voltage source, making it very easy to read it. However on some devices like ther ZEN X-Fi Style, the ladder is wired to VDDIO we can be changed so it's crucial that the button driver correctly scales the values wrt VDDIO.
