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.

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