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. 27 28 If unsure, say no. 29 30if PWM 31 32config PWM_DEBUG 33 bool "PWM lowlevel drivers additional checks and debug messages" 34 depends on DEBUG_KERNEL 35 help 36 This option enables some additional checks to help lowlevel driver 37 authors to get their callbacks implemented correctly. 38 It is expected to introduce some runtime overhead and diagnostic 39 output to the kernel log, so only enable while working on a driver. 40 41config PWM_AB8500 42 tristate "AB8500 PWM support" 43 depends on AB8500_CORE && ARCH_U8500 44 help 45 Generic PWM framework driver for Analog Baseband AB8500. 46 47 To compile this driver as a module, choose M here: the module 48 will be called pwm-ab8500. 49 50config PWM_ADP5585 51 tristate "ADP5585 PWM support" 52 depends on MFD_ADP5585 53 help 54 This option enables support for the PWM function found in the Analog 55 Devices ADP5585. 56 57config PWM_APPLE 58 tristate "Apple SoC PWM support" 59 depends on ARCH_APPLE || COMPILE_TEST 60 help 61 Generic PWM framework driver for PWM controller present on 62 Apple SoCs 63 64 Say Y here if you have an ARM Apple laptop, otherwise say N 65 66 To compile this driver as a module, choose M here: the module 67 will be called pwm-apple. 68 69config PWM_ATMEL 70 tristate "Atmel PWM support" 71 depends on ARCH_AT91 || COMPILE_TEST 72 depends on HAS_IOMEM && OF 73 help 74 Generic PWM framework driver for Atmel SoC. 75 76 To compile this driver as a module, choose M here: the module 77 will be called pwm-atmel. 78 79config PWM_ATMEL_HLCDC_PWM 80 tristate "Atmel HLCDC PWM support" 81 depends on MFD_ATMEL_HLCDC 82 depends on HAVE_CLK 83 help 84 Generic PWM framework driver for the PWM output of the HLCDC 85 (Atmel High-end LCD Controller).
