Technically you can also select GPIOLIB, because it is available on
all platforms, so it may be easier for users, but then you never know
which GPIOs you get in practice.
Yours,

Now that I think of it, wouldn't that be the better solution? I opted for
"depends on" only because Arnd did the same in his KTD2692 patch, but if
select is better (and it seems to be for users) then I'd go for that in both
patches.
