Counter devices
config I8254 tristate select COUNTER select REGMAP help Enables support for the i8254 interface library functions. The i8254 interface library provides functions to facilitate communication with interfaces compatible with the venerable Intel 8254 Programmable Interval Timer (PIT). The Intel 825x family of chips was first released in the early 1980s but compatible interfaces are nowadays typically found embedded in larger VLSI processing chips and FPGA components.
If built as a module its name will be i8254.
menuconfig COUNTER tristate "Counter support" help This enables counter device support through the Generic Counter interface. 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 depends on HAS_IOPORT_MAP select ISA_BUS_API select REGMAP_MMIO 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. The 104-QUAD-8
counters 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 FTM_QUADDEC tristate "Flex Timer Module Quadrature decoder driver" depends on SOC_LS1021A || COMPILE_TEST depends on HAS_IOMEM && OF help Select this option to enable the Flex Timer Quadrature decoder driver.
