  3         help
  4           Generic Pulse-Width Modulation (PWM) support.
  5 
  6           In Pulse-Width Modulation, a variation of the width of pulses
  7           in a rectangular pulse signal is used as a means to alter the
  8           average power of the signal. Applications include efficient
  9           power delivery and voltage regulation. In computer systems,
 10           PWMs are commonly used to control fans or the brightness of
 11           display backlights.
 12 
 13           This framework provides a generic interface to PWM devices
 14           within the Linux kernel. On the driver side it provides an API
 15           to register and unregister a PWM chip, an abstraction of a PWM
 16           controller, that supports one or more PWM devices. Client
 17           drivers can request PWM devices and use the generic framework
 18           to configure as well as enable and disable them.
 19 
 20           This generic framework replaces the legacy PWM framework which
 21           allows only a single driver implementing the required API. Not
 22           all legacy implementations have been ported to the framework
 23           yet. The framework provides an API that is backward compatible
 24           with the legacy framework so that existing client drivers
 25           continue to work as expected.

 27           If unsure, say no.
