0004 help
0005 Generic Pulse-Width Modulation (PWM) support.
0006
0007 In Pulse-Width Modulation, a variation of the width of pulses
0008 in a rectangular pulse signal is used as a means to alter the
0009 average power of the signal. Applications include efficient
0010 power delivery and voltage regulation. In computer systems,
0011 PWMs are commonly used to control fans or the brightness of
0012 display backlights.
0013
0014 This framework provides a generic interface to PWM devices
0015 within the Linux kernel. On the driver side it provides an API
0016 to register and unregister a PWM chip, an abstraction of a PWM
0017 controller, that supports one or more PWM devices. Client
0018 drivers can request PWM devices and use the generic framework
0019 to configure as well as enable and disable them.
0020
0021 This generic framework replaces the legacy PWM framework which
0022 allows only a single driver implementing the required API. Not
0023 all legacy implementations have been ported to the framework
0024 yet. The framework provides an API that is backward compatible
0025 with the legacy framework so that existing client drivers
0026 continue to work as expected.

0042 It is expected to introduce some runtime overhead and diagnostic
0043 output to the kernel log, so only enable while working on a driver.
