2 bool "Pulse-Width Modulation (PWM) Support"
3 depends on !MACH_JZ4740 && !PUV3_PWM
5 Generic Pulse-Width Modulation (PWM) support.
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
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.
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.
