Cover letter [PATCH 0/3] SPEAr320: Add pwm support

Sascha sent a patchset for something similar earlier. But don't know what happened to it.
Nothing yet, unfortunately. It was a straight forward implementation which basically implements the existing pwm functions and adds register/unregister functions.
Bill Gatliff posts a pwm framework since 2008. I wasn't aware of his patches by the time I wrote my pwm layer. Bills patches target more the motor controller use case and are (in my opinion) too complicated. I can't agree on his approach, but didn't want to go with competing patches either.

As Bills patches still didn't make it into the kernel Maybe it's time to respin my version.
Yes, I think that would be good, then we can add the new SPEAr320 pwm driver to the new subsystem as a first example, and move the other drivers over after that.
