| D | generic-counter.rst | 4 Generic Counter Interface
10 Counter devices are prevalent among a diverse spectrum of industries.
13 resolve the issue of duplicate code found among existing counter device
14 drivers by introducing a generic counter interface for consumption. The
15 Generic Counter interface enables drivers to support and expose a common
16 set of components and functionality present in counter devices.
21 Counter devices can vary greatly in design, but regardless of whether
23 counter devices consist of a core set of components. This core set of
24 components, shared by all counter devices, is what forms the essence of
25 the Generic Counter interface.
