PWM Weekly report

Hi all!
here is the weekly report

* Added more ioctl() calls to query the status of the PWM.
* Added some sample code to make using the driver easier.
* Still reading up on ALSA. I now think that I will have to write an
ALSA driver to access the PCM data being sent out to the soundcard and
convert it over to PWM to output sound on the beagle's PWM pins.
Should have something up next week

* A simple ALSA module should be working by next week.
