- 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.

- 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. Although the
- 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be
- set, either directly or via the counter's preset attribute. Interrupts
- are not supported by this driver.
- The base port addresses for the devices may be configured via the base
- array module parameter.

- Select this option to enable STM32 Timer quadrature encoder
- and counter driver.
- To compile this driver as a module, choose M here: the
