An example use case is a mobile phone OEM that wishes to set a period of 5 seconds or more for, say, a low battery slow blinking indication - currently this is not possible. The PWM framework not having direct support for blinking should not be a concern if the PWM peripheral being controlled supports it via register writes.

Will upload a new patchset adding more details in the summary patch.
Thank you.
