bcmgpio — driver
for BCM2835 onboard gpio
bcmgpio0 at obio?
bcmgpio1 at obio?
gpio* at gpiobus?
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 configurations
are not available for GPIO operations.
The bcmgpio driver first appeared in
NetBSD 7.0.
The bcmgpio driver was written by
