# SPDX-License-Identifier: GPL-2.0-only menuconfig PWM bool "Pulse-Width Modulation (PWM) Support" help 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. if PWM config PWM_SYSFS bool default y if SYSFS config PWM_DEBUG bool "PWM lowlevel drivers additional checks and debug messages" depends on DEBUG_KERNEL help This option enables some additional checks to help lowlevel driver authors to get their callbacks implemented correctly.
