From ef12379f205bed7e92434e12ddd44e62d13bebe1 Mon Sep 17 00:00:00 2001 From: Hartley Sweeten Date: Wed, 29 Jul 2009 22:41:06 +0100 Subject: ARM: 5628/1: ep93xx: Introduce Pulse Width Modulator (PWM) driver 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.
