| 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. |
