Module Name:    src
Committed By:   mbalmer
Date:           Sun Aug 28 07:48:51 UTC 2011

Modified Files:
        src/share/man/man4: gpio.4
        src/sys/dev/gpio: gpio.c gpiovar.h
        src/sys/sys: gpio.h
        src/usr.sbin/gpioctl: gpioctl.8 gpioctl.c

Log Message:
Add a new ioctl, GPIOPULSE to gpio(4) to allow for pulsing a pin.
If a pin can pulse in hardware, that will be used, else it will
be pulsed in software.  There is no way yet to set the pulse frequency
for pins that pulse in hardware.  While here, make the code mpsafe and
allow more than one thread in the driver (access to ioctl is serialized).
