The existing address space, and the patches Anton etc. just submitted
which I started this discussion to address, don't fulfil certain needs.

You could do better than call it insane, by describing how you would
define a gpio bank that used 3 seperate pins which are NOT together
in a register, using a base address (reg) and base property (offset
of first pin) with the current system?
