18 Inside a GPIO driver, individual GPIOs are identified by their hardware number,
19 which is a unique number between 0 and n, n being the number of GPIOs managed by
30 So for example one platform could use numbers 32-159 for GPIOs, with a
31 controller defining 128 GPIOs at a "base" of 32 ; while another platform uses
32 numbers 0..63 with one set of GPIO controllers, 64-79 with another type of GPIO
33 controller, and on one particular board 80-95 with an FPGA. The numbers need not
34 be contiguous; either of those platforms could also use numbers 2000-2063 to
