Although this functionality is now provided by the Counter subsystem, we
should keep the IIO Counter interface for this driver intact since
existing user applications may depend on it; this is the same reason why
the IIO Counter code in the 104-QUAD-8 device driver was not removed
despite moving to the Counter subsystem.

Once user applications have had enough time to migrate to the Generic
Counter interface, we can consider removing the deprecated IIO Counter
interface.
