Counters can often have a divider applied to their input clock and
therefore run at a scaled down frequency. This is not the case in the
first SoC where the sniffer is used, so for simplicity I can modify as
you suggest and remove that field from

I was trying to be somewhat generic here and not assume that it
is necessarily the same as the 'tstamp' clock below, in which c

Hi Mark,

+- tstamp-hz : frequency of the timestamp counter
Is this the frequency the clock is running at, or a frequency that it
should be programmed to in order to be used?
The former can be queried from the common clock framework, and if you
intended

Does this counter unit need to be enabled (or have any input clocks
enabled)?
