The 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 configura-
tions are not available for GPIO operations.
The bcmgpio driver first appeared in NetBSD 7.0.
The bcmgpio driver was written by Frank Kardel <kardel@NetBSD.org>.
