The first part of this set extends the current PWM API to allow external code to request a PWM Capture. Subsequent patches then make use of the new API by providing a userspace offering via /sysfs. The final part of the set supplies PWM Capture functionality into the already existing STi PWM driver. This patch-set has been tested end to end via /sysfs.
