Hi Bart!

This is my first time writing a driver in general, so the only reason is
that the drivers I used as a reference (gpio-it87 and gpio-winbond) look
more or less like this. I used those because they are fairly simple and
also use fixed x86 ports for control.

I see now on gpio-f7188x that it is possible to detect if the SoC matches
using platform_driver and platform_device. I guess that is what you were
referring to? Should I thus make a V2 patch using those facilities? 

Thanks,
Marcos
