The GPIOLIB allows the specification of a base gpio number for a

In order to allow static, predefined gpio numbers, a base property in
the gpio controller node specifies the first gpio number.
See my latest mail.
I don't think it's enough to say which pin the GPIOs exposed
start at; you need some sort of mask, or array of applicable
GPIOs so that GPIOLIB can check which perhaps 3 pins out of a
possible 32 are allocated to a controller and usable (these
may be pin 5, pin 9 and pin 20, so a "base" of pin 5 would be
outrageously inadequate).
