A defined counter_device structure may be registered to the system by
passing it to the counter_register function, and unregistered by passing
it to the counter_unregister function. Similarly, the
devm_counter_register function may be used if device memory-managed
registration is desired.
A counter_device structure is allocated using counter_alloc() and then
registered to the system by passing it to the counter_add() function, and
unregistered by passing it to the counter_unregister function. There are
device managed variants of these functions: devm_counter_alloc() and
devm_counter_add().
The struct counter_comp structure is used to define counter extensions
for Signals, Synapses, and Counts.
