DESCRIPTION

     The bytgpio is a driver for GPIO controller that can be found in Intel's Bay Trail SoC
     family.

     Bay Trail SoC has three banks of GPIO pins exposed to userland as /dev/gpiocN, where N is 0,
     1, and 2. Pins in each bank are pre-named to match names on boards schematics: GPIO_S0_SCnn,
     GPIO_S0_NCnn, and GPIO_S5_nn.
