Style is good, code looks clean

One big thing that needs fixing here is the function names. If the driver gets linked into the kernel then the symbols become global - and names like enableGPIO are asking for clashes. The viafb code is fine as it uses viafb_ as the function names. Possibly the helper functions should doo something similar.

We also have a generic i2c layer that might be usable but that is something that could be addressed in the future and isn't really an important detail.
