* Add a new ioctl to allow the setting of GPIO pin names.loos2015-03-081-0/+5
| | | | | | | | | | | | | 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. Differential Revision: https://reviews.freebsd.org/D2002 Reviewed by: rpaulo Requested by: many

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.
