The EP93xx features two PWMs (one on the EP9307) with the following features: * Configurable dual output * Separate input clocks for each PWM output * 16-bit resolution * Programmable pulse width (duty cycle), interval (frequency), and polarity This adds the necessary core support as well as the driver. A sysfs interface is provided to control the PWM outputs.
