Module Name:    src
Committed By:   mbalmer
Date:           Sat Jul 25 16:17:10 UTC 2009

Modified Files:
        src/sys/dev/gpio: files.gpio gpio.c gpioow.c gpiovar.h
        src/sys/sys: gpio.h
Added Files:
        src/sys/dev/gpio: gpiosim.c

Log Message:
Rework the GPIO framework.  Tie it to the kauth(9) framework to control
access to the GPIO pins.  Device drivers using GPIO pins can now be
attached and detached at runtime.  GPIO pins can be named for easier
reference from userland programs.  Introduce a new gpiosim(4) driver,
which is used for development.
