  	bool "Pulse-Width Modulation (PWM) Support"

  	help

  	  Generic Pulse-Width Modulation (PWM) support.

  	  In Pulse-Width Modulation, a variation of the width of pulses
  	  in a rectangular pulse signal is used as a means to alter the
  	  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.
