Applications include efficient10 power delivery and voltage regulation. In computer systems,11 PWMs are commonly used to control fans or the brightness of12 display backlights.13 14 This framework provides a generic interface to PWM devices15 within the Linux kernel. On the driver side it provides an API16 to register and unregister a PWM chip, an abstraction of a PWM17 controller, that supports one or more PWM devices. Client18 drivers can request PWM devices and use the generic framework19 to configure as well as enable and disable them.20 21 This generic framework replaces the legacy PWM framework which22 allows only a single driver implementing the required API. Not23 all legacy implementations have been ported to the framework24 yet. The framework provides an API that is backward compatible25 with the legacy framework so that existing client drivers26 continue to work as expected.27 28 If unsure, say no.29 30if PWM31 32config PWM_DEBUG33 bool "PWM lowlevel drivers additional checks and debug messages"34 depends on DEBUG_KERNEL35 help36 This option enables some additional checks to help lowlevel driver37 authors to get their callbacks implemented correctly.38 It is expected to introduce some runtime overhead and diagnostic39 output to the kernel log, so only enable while working on a driver.40 41config PWM_AB850042 tristate "AB8500 PWM support"43 depends on AB8500_CORE && ARCH_U850044 help45 Generic PWM framework driver for Analog Baseband AB8500.46 47 To compile this driver as a module, choose M here: the module48 will be called pwm-ab8500.49 50config PWM_ADP558551 tristate "ADP5585 PWM support"52 depends on MFD_ADP558553 help54 This option enables support for the PWM function found in the Analog55 Devices ADP5585.56 57config PWM_APPLE58 tristate "Apple SoC PWM support"59 depends on ARCH_APPLE || COMPILE_TEST60 help61 Generic PWM framework driver for PWM controller present on62 Apple SoCs63 64 Say Y here if you have an ARM Apple laptop, otherwise say N65 66 To compile this driver as a module, choose M here: the module67 will be called pwm-apple.68 69config PWM_ATMEL70 tristate "Atmel PWM support"71 depends on ARCH_AT91 || COMPILE_TEST72 depends on HAS_IOMEM && OF73 help74 Generic PWM framework driver for Atmel SoC.75 76 To compile this driver as a module, choose M here: the module77 will be called pwm-atmel.78 79config PWM_ATMEL_HLCDC_PWM80 tristate "Atmel HLCDC PWM support"81 depends on MFD_ATMEL_HLCDC82 depends on HAVE_CLK83 help84 Generic PWM framework driver for the PWM output of the HLCDC85 (Atmel High-end LCD Controller).
