7	tristate "Counter support"
8	help
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.

19	help
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).
22
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.
27
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.
