Vendor: Digilent, Inc.

Description

GPIO pins exposed on a Digilent Pmod interface.

This binding provides a nexus mapping for 8 pins where parent pins 0
through 3 correspond to IO1 through IO4, and parent pins 4 through 7
correspond to IO5 through IO8, as depicted below for a 12-pin connector.

12-pin Pmod interface:

    0 IO1                    IO5   4
    1 IO2                    IO6   5
    2 IO3                    IO7   6
    3 IO4                    IO8   7
    - GND                    GND   -
    - VDD                    VDD   -

This binding can also be used with the 6-pin Pmod connector variant which
is a proper subset of the 12-pin connector. In that case parent pins 4
through 7 are omitted from the GPIO nexus node, resulting in a mapping
as depicted below.

6-pin Pmod interface:

    0 IO1
    1 IO2
    2 IO3
    3 IO4
    - GND
    - VDD
