14     description: Number of items to expect in a GPIO specifier
19         This property indicates the number of in-use slots of available slots
20         for GPIOs. The typical example is something like this: the hardware
23         be used, but the IP block is reused in a lot of designs, some using
24         all 32 bits, some using 18 and some using 12. In this case, setting
25         "ngpios = <18>;" informs the driver that only the first 18 GPIOs, at
26         local offset 0 .. 17, are in use.  For cases in which there might be
27         holes in the slot range, this value should be the max slot number+1.
28   gpio-reserved-ranges:
31         If not all the GPIOs at offsets 0...N-1 are usable for ngpios = <N>, then
32         this property contains an additional set of tuples which specify which GPIOs
33         are unusable. This property indicates the start and size of the GPIOs
36         For example, setting "gpio-reserved-ranges = <3 2>, <10 1>;" means that
