c4839d320a Use GPIOTOGGLE to toggle the pin state instead of read, modify and write. 2016-04-19 15:18:31 +00:00

d752f0f69d Add a new ioctl to allow the setting of GPIO pin names.
When a gpiobus child is added, use its name to identify the mapped pin
names.

Make the respective changes to libgpio.

Add a new '-n' flag to gpioctl(8) to set the pin name.

f12128e4df Import libgpio.
This is a thin wrapper around the kernel interface which should make
it easier to write GPIO applications.  gpioctl(8) will be converted to
use this library in a separate commit.
