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_SYSFS 33 bool 34 default y if SYSFS 35 36config PWM_DEBUG 37 bool "PWM lowlevel drivers additional checks and debug messages" 38 depends on DEBUG_KERNEL 39 help 40 This option enables some additional checks to help lowlevel driver 41 authors to get their callbacks implemented correctly. 42 It is expected to introduce some runtime overhead and diagnostic 43 output to the kernel log, so only enable while working on a driver. 44 45config PWM_AB8500 46 tristate "AB8500 PWM support" 47 depends on AB8500_CORE && ARCH_U8500 48 help 49 Generic PWM framework driver for Analog Baseband AB8500. 50 51 To compile this driver as a module, choose M here: the module 52 will be called pwm-ab8500. 53 54config PWM_APPLE 55 tristate "Apple SoC PWM support" 56 depends on ARCH_APPLE || COMPILE_TEST 57 help 58 Generic PWM framework driver for PWM controller present on 59 Apple SoCs 60 61 Say Y here if you have an ARM Apple laptop, otherwise say N 62 63 To compile this driver as a module, choose M here: the module 64 will be called pwm-apple. 65 66config PWM_ATMEL 67 tristate "Atmel PWM support" 68 depends on ARCH_AT91 || COMPILE_TEST 69 depends on HAS_IOMEM && OF 70 help 71 Generic PWM framework driver for Atmel SoC. 72 73 To compile this driver as a module, choose M here: the module 74 will be called pwm-atmel. 75 76config PWM_ATMEL_HLCDC_PWM 77 tristate "Atmel HLCDC PWM support" 78 depends on MFD_ATMEL_HLCDC 79 depends on HAVE_CLK 80 help 81 Generic PWM framework driver for the PWM output of the HLCDC 82 (Atmel High-end LCD Controller).
