[[RFC] 0/5] Generic PWM API Proposal

This patch series extends the existing PWM API into something more generic, and adds support for hotplugging. A driver for the Atmel SAM9263 PWMC peripheral is provided, as well as a leds-pwm wedge and an led-dim trigger that allow the LED API to take advantage of this new API. The code has
