The i825412 interface library provides functions to facilitate communication with13 interfaces compatible with the venerable Intel 8254 Programmable14 Interval Timer (PIT). The Intel 825x family of chips was first15 released in the early 1980s but compatible interfaces are nowadays16 typically found embedded in larger VLSI processing chips and FPGA17 components.18 19 If built as a module its name will be i8254.20 21menuconfig COUNTER22 tristate "Counter support"23 help24 This enables counter device support through the Generic Counter25 interface.
