Is there a reason you decided to not put this driver in IIO? IMHO, it
would be more appropriate to make your PWM device an MFD that can either
bind to the PWM or the capture driver.
And BTW, IIO already has a sysfs interface (you may have to extend the
API to support your type of capture though).

Best Regards,

Boris
