-          You only need to enable this, if you also want to enable
-          one or more of the PWM drivers below.
+          In Pulse-Width Modulation, a variation of the width of pulses
+          in a rectangular pulse signal is used as a means to alter the
-          If unsure, say N.
+          average power of the signal. Applications include efficient
+          power delivery and voltage regulation. In computer systems,
+          PWMs are commonly used to control fans or the brightness of
+          display backlights.
+          This framework provides a generic interface to PWM devices
+          within the Linux kernel. On the driver side it provides an API
+          to register and unregister a PWM chip, an abstraction of a PWM
+          controller, that supports one or more PWM devices. Client
+          drivers can request PWM devices and use the generic framework
+          to configure as well as enable and disable them.
+          This generic framework replaces the legacy PWM framework which
+          allows only a single driver implementing the required API. Not
+          all legacy implementations have been ported to the framework
+          yet. The framework provides an API that is backward compatible
+          with the legacy framework so that existing client drivers
+          continue to work as expected.
+          If unsure, say no.
