I posted a generic PWM API on linux-embedded, after posting an initial
version here for review.  The architecture is very similar to the gpio
approach: a common frontend that binds to device-specific drivers.
Might consider checking that out.

The code I posted contained an example driver for the Atmel PWMC
peripheral, and I also have a pseudo-device implementation that uses
gpio plus an hrtimer.  Supporting the TC peripheral found in the
RM9200 wouldn't be a big deal, especially after you see the code.
