>
> After commit da5dd31efd24 ("gpio: vf610: Switch to gpio-mmio"), the vf610
> GPIO driver no longer uses the static number 32 for
> gc->ngpio. This allows users to configure the number of GPIOs
> per port.
>
> And some gpio controllers did have less pads. So add 'ngpios' here, this can save
> some memory when request bitmap, and also show user more accurate
> information when use gpio tools.
>
> Besides, some gpio controllers have hole in the gpio ranges, so use
> 'gpio-reserved-ranges' to cover that, then the gpioinfo tool show the correct
> result.
