Hi! I don't know much about the sysfs PWM capabilities. But I know a bit about the AM335x CPU. It has three PWMSS subsystems, each has a PWM module, each has two outputs (A and B). So there're six PWM outputs in total. I guess this is what sysfs supports.
Additionaly you can generate PWM pulse trains by the eCAP modules (also integrated in each PWMSS). AFAIK this isn't supported by sysfs (but libpruio <http://beagleboard.org/project/libpruio/> can handle that). Only two eCAP output pins are available on the BBB headers (P9_28 and P9_42). So you can have a maximum of eight PWM outputs at a time.
