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.
