Hi Arun,
Because you have Bill Gatliff on Cc, I'm guessing you've already looked
at his RFC for a generic PWM framework?
There's recently been a proposal on DaVinci that is similar to yours
that enables multiple PWM drivers, but it would be nice to have a common
framework for this, and what Bill has proposed seems to be a good
solution.
