4 | help | |
5 | Generic Pulse-Width Modulation (PWM) support. | |
6 | ||
7 | In Pulse-Width Modulation, a variation of the width of pulses | |
8 | in a rectangular pulse signal is used as a means to alter the | |
9 | average power of the signal. Applications include efficient | |
10 | power delivery and voltage regulation. In computer systems, | |
11 | PWMs are commonly used to control fans or the brightness of | |
12 | display backlights. | |
13 | ||
14 | This framework provides a generic interface to PWM devices | |
15 | within the Linux kernel. On the driver side it provides an API | |
16 | to register and unregister a PWM chip, an abstraction of a PWM | |
17 | controller, that supports one or more PWM devices. Client | |
18 | drivers can request PWM devices and use the generic framework | |
19 | to configure as well as enable and disable them. | |
20 | ||
21 | This generic framework replaces the legacy PWM framework which | |
22 | allows only a single driver implementing the required API. Not | |
23 | all legacy implementations have been ported to the framework | |
24 | yet. The framework provides an API that is backward compatible | |
25 | with the legacy framework so that existing client drivers | |
26 | continue to work as expected. | |

42 | It is expected to introduce some runtime overhead and diagnostic | |
