You only need to enable this, if you also want to enable one or more of the counter device drivers below. if COUNTER config 104_QUAD_8 tristate "ACCES 104-QUAD-8 driver" depends on (PC104 && X86) || COMPILE_TEST select ISA_BUS_API help Say yes here to build support for the ACCES 104-QUAD-8 quadrature encoder counter/interface device family (104-QUAD-8, 104-QUAD-4). A counter's respective error flag may be cleared by performing a write operation on the respective count value attribute. Although the 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be set, either directly or via the counter's preset attribute. The base port addresses for the devices may be configured via the base array module parameter. The interrupt line numbers for the devices may be configured via the irq array module parameter. config INTERRUPT_CNT tristate "Interrupt counter driver" depends on GPIOLIB help Select this option to enable interrupt counter driver. Any interrupt source can be used by this driver as the event source. To compile this driver as a module, choose M here: the module will be called interrupt-cnt. config STM32_TIMER_CNT tristate "STM32 Timer encoder counter driver" depends on MFD_STM32_TIMERS || COMPILE_TEST help Select this option to enable STM32 Timer quadrature encoder and counter driver. To compile this driver as a module, choose M here: the module will be called stm32-timer-cnt. config STM32_LPTIMER_CNT tristate "STM32 LP Timer encoder counter driver" depends on MFD_STM32_LPTIMER || COMPILE_TEST help Select this option to enable STM32 Low-Power Timer quadrature encoder and counter driver. To compile this driver as a module, choose M here: the module will be called stm32-lptimer-cnt. config TI_EQEP tristate "TI eQEP counter driver" depends on (SOC_AM33XX || COMPILE_TEST) select REGMAP_MMIO help Select this option to enable the Texas Instruments Enhanced Quadrature Encoder Pulse (eQEP) counter driver. To compile this driver as a module, choose M here: the module will be called ti-eqep. config FTM_QUADDEC tristate "Flex Timer Module Quadrature decoder driver" depends on HAS_IOMEM && OF help Select this option to enable the Flex Timer Quadrature decoder driver. To compile this driver as a module, choose M here: the module will be called ftm-quaddec. config MICROCHIP_TCB_CAPTURE tristate "Microchip Timer Counter Capture driver" depends on HAS_IOMEM && OF select REGMAP_MMIO help Select this option to enable the Microchip Timer Counter Block capture driver. To compile this driver as a module, choose M here: the module will be called microchip-tcb-capture. config INTEL_QEP tristate "Intel Quadrature Encoder Peripheral driver" depends on PCI help Select this option to enable the Intel Quadrature Encoder Peripheral driver. To compile this driver as a module, choose M here: the module will be called intel-qep. config TI_ECAP_CAPTURE tristate "TI eCAP capture driver" depends on ARCH_OMAP2PLUS || ARCH_DAVINCI_DA8XX || ARCH_KEYSTONE || ARCH_K3 || COMPILE_TEST depends on HAS_IOMEM select REGMAP_MMIO help Select this option to enable the Texas Instruments Enhanced Capture (eCAP) driver in input mode. It can be used to timestamp events (falling/rising edges) detected on ECAP input signal. To compile this driver as a module, choose M here: the module will be called ti-ecap-capture. endif # COUNTER |
