  4. help
  5. Generic Pulse-Width Modulation (PWM) support.
  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. This framework provides a generic interface to PWM devices
  13. within the Linux kernel. On the driver side it provides an API
  14. to register and unregister a PWM chip, an abstraction of a PWM
  15. controller, that supports one or more PWM devices. Client
  16. drivers can request PWM devices and use the generic framework
  17. to configure as well as enable and disable them.
  18. This generic framework replaces the legacy PWM framework which
  19. allows only a single driver implementing the required API. Not
  20. all legacy implementations have been ported to the framework
  21. yet. The framework provides an API that is backward compatible
  22. with the legacy framework so that existing client drivers
  23. continue to work as expected.
