7 tristate "Counter support"
9 This enables counter device support through the Generic Counter
10 interface. You only need to enable this, if you also want to enable
11 one or more of the counter device drivers below.
16 tristate "ACCES 104-QUAD-8 driver"
17 depends on (PC104 && X86) || COMPILE_TEST
20 Say yes here to build support for the ACCES 104-QUAD-8 quadrature
21 encoder counter/interface device family (104-QUAD-8, 104-QUAD-4).
23 A counter's respective error flag may be cleared by performing a write
24 operation on the respective count value attribute. Although the
25 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be
26 set, either directly or via the counter's preset attribute.
28 The base port addresses for the devices may be configured via the base
29 array module parameter. The interrupt line numbers for the devices may
30 be configured via the irq array module parameter.
33 tristate "Flex Timer Module Quadrature decoder driver"
34 depends on SOC_LS1021A || COMPILE_TEST
35 depends on HAS_IOMEM && OF
37 Select this option to enable the Flex Timer Quadrature decoder
40 To compile this driver as a module, choose M here: the
41 module will be called ftm-quaddec.
44 tristate "Intel Quadrature Encoder Peripheral driver"
48 Select this option to enable the Intel Quadrature Encoder Peripheral
51 To compile this driver as a module, choose M here: the module
52 will be called intel-qep.
55 tristate "Interrupt counter driver"
58 Select this option to enable interrupt counter driver. Any interrupt
59 source can be used by this driver as the event source.
61 To compile this driver as a module, choose M here: the
62 module will be called interrupt-cnt.
64 config MICROCHIP_TCB_CAPTURE
65 tristate "Microchip Timer Counter Capture driver"
66 depends on SOC_AT91SAM9 || SOC_SAM_V7 || COMPILE_TEST
67 depends on HAS_IOMEM && OF
70 Select this option to enable the Microchip Timer Counter Block
73 To compile this driver as a module, choose M here: the
74 module will be called microchip-tcb-capture.
77 tristate "Renesas RZ/G2L MTU3a counter driver"
78 depends on RZ_MTU3 || COMPILE_TEST
80 Enable support for MTU3a counter driver found on Renesas RZ/G2L alike
81 SoCs. This IP supports both 16-bit and 32-bit phase counting mode
84 To compile this driver as a module, choose M here: the
85 module will be called rz-mtu3-cnt.
87 config STM32_LPTIMER_CNT
88 tristate "STM32 LP Timer encoder counter driver"
89 depends on MFD_STM32_LPTIMER || COMPILE_TEST
91 Select this option to enable STM32 Low-Power Timer quadrature encoder
94 To compile this driver as a module, choose M here: the
95 module will be called stm32-lptimer-cnt.
97 config STM32_TIMER_CNT
98 tristate "STM32 Timer encoder counter driver"
99 depends on MFD_STM32_TIMERS || COMPILE_TEST
101 Select this option to enable STM32 Timer quadrature encoder
104 To compile this driver as a module, choose M here: the
105 module will be called stm32-timer-cnt.

108 tristate "TI eCAP capture driver"
109 depends on ARCH_OMAP2PLUS || ARCH_DAVINCI_DA8XX || ARCH_KEYSTONE || ARCH_K3 || COMPILE_TEST
113 Select this option to enable the Texas Instruments Enhanced Capture
114 (eCAP) driver in input mode.
