  3	bool "Pulse-Width Modulation (PWM) Support"
  4	help
  5	  Generic Pulse-Width Modulation (PWM) support.
  6
  7	  In Pulse-Width Modulation, a variation of the width of pulses
  8	  in a rectangular pulse signal is used as a means to alter the
  9	  average power of the signal. Applications include efficient
 10	  power delivery and voltage regulation. In computer systems,
 11	  PWMs are commonly used to control fans or the brightness of
 12	  display backlights.
 13
 14	  This framework provides a generic interface to PWM devices
 15	  within the Linux kernel. On the driver side it provides an API
 16	  to register and unregister a PWM chip, an abstraction of a PWM
 17	  controller, that supports one or more PWM devices. Client
 18	  drivers can request PWM devices and use the generic framework
 19	  to configure as well as enable and disable them.
 20
 21	  This generic framework replaces the legacy PWM framework which
 22	  allows only a single driver implementing the required API. Not
 23	  all legacy implementations have been ported to the framework
 24	  yet. The framework provides an API that is backward compatible
 25	  with the legacy framework so that existing client drivers
 26	  continue to work as expected.
 27
 28	  If unsure, say no.

  3	bool "Pulse-Width Modulation (PWM) Support"
  4	help
  5	  Generic Pulse-Width Modulation (PWM) support.
  6
  7	  In Pulse-Width Modulation, a variation of the width of pulses
  8	  in a rectangular pulse signal is used as a means to alter the
  9	  average power of the signal. Applications include efficient
 10	  power delivery and voltage regulation. In computer systems,
 11	  PWMs are commonly used to control fans or the brightness of
 12	  display backlights.
 13
 14	  This framework provides a generic interface to PWM devices
 15	  within the Linux kernel. On the driver side it provides an API
 16	  to register and unregister a PWM chip, an abstraction of a PWM
 17	  controller, that supports one or more PWM devices. Client
 18	  drivers can request PWM devices and use the generic framework
 19	  to configure as well as enable and disable them.
 20
 21	  This generic framework replaces the legacy PWM framework which
 22	  allows only a single driver implementing the required API. Not
 23	  all legacy implementations have been ported to the framework
 24	  yet. The framework provides an API that is backward compatible
 25	  with the legacy framework so that existing client drivers
 26	  continue to work as expected.
 27
 28	  If unsure, say no.
