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.
