various Synapses and Counts respectively.

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.
