I'd say let's go forward with your framework. The two patches currently
because they both add Makefile/Kconfig files in drivers/pwm.

Maybe you can add Viresh's patch to your series, and wait for him
to follow up with a patch to convert it?

I've tried to blindly do the conversion myself, but got stuck with the
definition of the platform device that has multiple pwms in it.
I wonder if it would be better to change the st-pwm platform
interface to define one platform_device for each of them.
