DESCRIPTION

     View SoC family.

     The Cherry View SoC has 5 banks of GPIO pins, NORTH, EAST, SOUTHEAST,
     SOUTHWEST and VIRTUAL.  All but VIRTUAL are exposed to userland as
     /dev/gpiocN, where N is 0-3.  Pins in each bank are pre-named to match
     names in the Intel(R) Atomtm Z8000 Processor Series Vol 2
