High level interface to exploit the Pulse Width Modulation abilities of the BeagleBoard

by neo01124 for BeagleBoard.org

The main aim of this project will be to provide a high level interface for the Pulse Width Modulation output pins of the OMAP3 found on the BeagleBoard. Another aim will be to push this driver upstream(the Linux-OMAP tree). Two applications will be developed to demonstrate the use of this driver: 1) Motor control using PWM signals generated by the BeagleBoard using the PWM driver. 2) Writing a glue layer for ALSA to communicate with the PWM driver and output sound from the PWM output pins.
