PWM week 12 report

I was busy this week with some urgent college work, so could not put
in as much time.

* Improved the documentation on the elinux wiki page.

* Made a patch and submitted it to the linux-omap mailing list for
review. I sent in the patch this morning so am still waiting for some
opinions about it. I am hoping I have got the basics right.

* I will try and put some more time into testing the pwm speaker
