bcmgpio driver supports up to two instances. Access to the pins is provided by the 
gpio(4) interface. The 
bcmgpio unitnumber argument selects the pin range. Unit 0 covers GPIO pins 0 through 31 and unit 1 covers pins 32 through 53. GPIO pins being used in alternate configurations are not available for GPIO operations.
